Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
Summary 
With congressional approval, the Nixon Administration established the Environmental Protection 
Agency (EPA) in 1970 under an executive branch reorganization plan, which consolidated 
numerous federal pollution control responsibilities that had been divided among several federal 
agencies. EPA’s responsibilities grew over time as Congress enacted an increasing number of 
environmental statutes and major amendments to these statutes. EPA’s primary responsibilities 
have evolved to include the regulation of air quality, water quality, and chemicals in commerce; 
the development of regulatory criteria for the management and disposal of solid and hazardous 
wastes; and the cleanup of environmental contamination. The implementation and enforcement of 
many of these federal authorities is delegated to the states. EPA also provides financial assistance 
to states and local governments to aid them in administering pollution control programs and in 
complying with certain federal environmental requirements. Several federal statutes provide the 
legal authority for EPA’s programs and activities. The major provisions of each of the following 
statutes are summarized in this report, as laid out in existing law as of this writing. 
The Clean Air Act (CAA) authorizes EPA to set mobile source limits, ambient air quality 
standards, hazardous air pollutant emission standards, standards for new pollution sources, and 
significant deterioration requirements; to identify areas that do not attain federal ambient air 
quality standards set under the act; to administer a cap-and-trade program to reduce acid rain; and 
to phase out substances that deplete the Earth’s stratospheric ozone layer. 
The Clean Water Act (CWA) authorizes the regulation and enforcement of requirements that 
govern waste discharges into U.S. waters, and financial assistance for wastewater treatment plant 
construction and improvements. The Ocean Dumping Act focuses on the regulation of the 
intentional disposal of materials into ocean waters and authorizes related research. The Safe 
Drinking Water Act (SDWA) authorizes EPA to establish primary drinking water standards, 
regulate underground injection disposal practices, and administer a groundwater control program. 
The Solid Waste Disposal Act and Resource Conservation and Recovery Act (RCRA) govern 
the regulation of solid and hazardous wastes, and corrective actions to address improper waste 
management practices. The Comprehensive Environmental Response, Compensation, and 
Liability Act (CERCLA) focuses on the cleanup of contamination resulting from the past release 
of hazardous substances, but excludes petroleum which primarily is covered under the Oil 
Pollution Act. Amendments to the Solid Waste Disposal Act specifically address the cleanup of 
petroleum leaked from underground storage tanks that are not covered under CERCLA. 
The Toxic Substances Control Act (TSCA) and the Federal Insecticide, Fungicide, and 
Rodenticide Act (FIFRA) require regulation of commercial chemicals to reduce risks to human 
health and the environment. The Pollution Prevention Act (PPA) authorizes various mechanisms 
intended to prevent pollution by reducing the generation of pollutants at the point of origin. The 
Emergency Planning and Community Right-to-Know Act (EPCRA) requires industrial 
reporting of toxic releases and encourages chemical emergency response planning. 
Under these and other statutes, Congress has assigned EPA the administration of a considerable 
body of law and associated programs and activities. This report is not comprehensive in terms of 
summarizing all laws administered by EPA, but covers the major, basic statutory authorities 
underlying the agency’s programs and activities, and those which EPA has delegated to the states.

Introduction 
The origin of the Environmental Protection Agency (EPA) is rooted in a reorganization of the 
executive branch under the Nixon Administration. Reorganization Plan No. 3 of 1970 proposed 
the establishment of EPA to integrate the administration of numerous federal pollution control 
laws that had been carried out by several federal agencies.1 This plan was part of a broader effort 
to reorganize an array of environmental responsibilities of many federal agencies, which also 
resulted in the creation of the National Oceanic and Atmospheric Administration (NOAA).2 The 
Nixon Administration created EPA and NOAA through this reorganization with congressional 
approval under procedures established in the Reorganization Act of 1949, as amended.3 
The Reorganization Act authorizes the President to propose reorganizations to Congress that 
would promote the “better execution” of federal laws, the “more effective” management of 
individual agencies and their functions, and the “efficiency of the operations of Government to 
the fullest extent practicable.”4 President Nixon determined that the consolidation of federal 
pollution control responsibilities under one agency was necessary to meet these statutory 
objectives, and proposed a reorganization of the executive branch to establish EPA under 
Reorganization Plan No. 3. The plan was based largely on recommendations of the “Ash 
Council,” which President Nixon had formed to examine the organization of environmental 
responsibilities among federal agencies.5 The 91st Congress approved this plan, leading to the 
creation of EPA on December 2, 1970.6  
Over time, EPA’s authorities have grown as Congress has enacted an increasing number of 
environmental statutes and major amendments to these statutes. EPA’s primary responsibilities 
have evolved to include the regulation of air quality, water quality, and chemicals in commerce; 
the development of regulatory criteria for the management and disposal of solid and hazardous 
wastes; and the cleanup of environmental contamination. Although EPA sets uniform pollution 
control standards and regulations on a national level, the implementation and enforcement of 
many of these federal standards and regulations are delegated to the states. EPA also provides 
financial assistance in the form of grants to states and local governments to aid them in 
administering pollution control programs and in complying with certain federal environmental 
requirements. The states also have enacted their own pollution control authorities and programs, 
which complement the federal role of EPA in protecting human health and the environment. 
This report presents a summary of the body of federal environmental statutes that together 
constitute the main authorities of EPA, but this report is not comprehensive in terms of discussing

individual programs and activities of federal agencies transferred to EPA.

all federal statutes that may authorize certain activities of the agency.7 This report highlights 
prominent provisions of the selected statutes discussed herein, characterizes the purpose and 
scope of major programs and activities authorized in each statute, and explains the definitions of 
key statutory terms that establish the parameters of the agency’s authorities in these instances. 
Although Congress somewhat recently has renewed the authorization of appropriations for certain 
EPA programs and activities through targeted amendments to various statutes, a more 
comprehensive reauthorization of many of the statutes that EPA administers has not been enacted 
for a number of years. Even though the authorization of appropriations may expire, program 
authority (often referred to as an agency’s “enabling” authority) generally does not expire unless 
repealed, or unless there is a “sunset” date for the program authority itself. If the authorization of 
appropriations for a specific program or activity has expired, Congress still may provide funding 
through the annual appropriations process to continue that program or activity, if certain rules for 
floor consideration are not enforced or are waived. 
House and Senate rules generally do not allow the appropriation of funding for a program or 
activity that Congress has not authorized in law, but these rules are subject to points of order and 
are not self-enforcing. Congress therefore may appropriate funding for a specific program or 
activity for which the authorization of appropriations has expired, if no Member raises a point of 
order, or the rules are waived for consideration of a particular bill. Congress typically has done so 
to continue the appropriation of funding for EPA programs and activities for which the 
authorization of appropriations has expired. Once enacted, appropriations provide the legal 
authority for an agency to obligate federal funds in that particular fiscal year.8 Congress 
appropriates funding for EPA within the Interior, Environment, and Related Agencies annual 
appropriations bill.9 (For a discussion of funding for FY2012, see the “Environmental Protection 
Agency” section in CRS Report R41896, Interior, Environment, and Related Agencies: FY2012 
Appropriations, coordinated by Carol Hardy Vincent.) 
This report focuses primarily on EPA’s program authorities under the statutes discussed herein. A 
list of major amendments to the parent statute is provided at the beginning of each summary. The 
final table at the end of each summary lists the individual provisions of the statute, cross-
referencing the sections of the public laws to the sections of the United States Code where each 
provision is codified. The summaries in this report outline the major provisions of each statute, 
but are not comprehensive in terms of discussing every provision of these statutes in their 
entirety. For the purpose of brevity, the summaries omit certain details and secondary provisions 
that would necessitate a lengthier examination. Furthermore, some prominent provisions are only 
briefly mentioned, which are beyond the scope of the summaries provided herein. 
                                                                  
7 For example, the National Environmental Education Act of 1990 (P.L. 101-619) authorized EPA to award grants to 
elementary and secondary schools to support environmental education. 
8 For a discussion of these and other budgetary procedures, see CRS Report 98-721, Introduction to the Federal Budget 
Process, coordinated by Bill Heniff Jr. 
9 During the 109th Congress, EPA’s funding was moved from the jurisdiction of the House and Senate Appropriations 
Subcommittees on Veterans Affairs, Housing and Urban Development, and Independent Agencies to the Interior, 
Environment, and Related Agencies Appropriations Subcommittees, beginning with the FY2006 appropriations. This 
change resulted from the abolition of the House and Senate Appropriations Subcommittees on Veterans Affairs, 
Housing and Urban Development, and Independent Agencies. This subcommittee jurisdiction was transferred among 
the remaining subcommittees of the House and Senate Committees on Appropriations.

Moreover, this report provides an analytical summary of the major provisions of the statutes as 
laid out in existing law as of this writing. This report does not examine issues associated with 
their implementation or with regulations that EPA may have proposed or promulgated to carry out 
these statutes. Other CRS reports offer information on current developments and issues associated 
with the implementation of various statutory authorities of EPA and the agency’s regulatory role 
under these statutes. (For a discussion of certain regulatory actions that have received recent 
attention, see CRS Report R41561, EPA Regulations: Too Much, Too Little, or On Track?, by 
James E. McCarthy and Claudia Copeland.) 
Clean Air Act10 
The Clean Air Act, codified as 42 U.S.C. 7401 et seq., seeks to protect human health and the 
environment from emissions that pollute ambient, or outdoor, air. It requires the Environmental 
Protection Agency to establish minimum national standards for air quality, and assigns primary 
responsibility to the states to assure compliance with the standards. Areas not meeting the 
standards, referred to as “nonattainment areas,” are required to implement specified air pollution 
control measures. The act establishes federal standards for mobile sources of air pollution and 
their fuels and for sources of 187 hazardous air pollutants, and it establishes a cap-and-trade 
program for the emissions that cause acid rain. It establishes a comprehensive permit system for 
all major sources of air pollution. It also addresses the prevention of pollution in areas with clean 
air and protection of the stratospheric ozone layer. 
Background 
Like many other programs administered by the Environmental Protection Agency, federal efforts 
to control air pollution have gone through several phases, beginning with information collection, 
research, and technical assistance, before being strengthened to establish federal standards and 
enforcement. Federal legislation addressing air pollution was first passed in 1955, prior to which 
air pollution was the exclusive responsibility of state and local levels of government. 
The federal role was strengthened in subsequent amendments, notably the Clean Air Act 
Amendments of 1970, 1977, and 1990. The 1970 amendments established the procedures under 
which EPA sets national standards for air quality, required a 90% reduction in emissions from 
new automobiles by 1975, established a program to require the best available control technology 
at major new sources of air pollution, established a program to regulate air toxics, and greatly 
strengthened federal enforcement authority. The 1977 amendments adjusted the auto emission 
standards, extended deadlines for the attainment of air quality standards, and added the 
Prevention of Significant Deterioration program to protect air cleaner than national standards. 
Changes to the act in 1990 included provisions to (1) classify most nonattainment areas according 
to the extent to which they exceed the standard, tailoring deadlines, planning, and controls to each 
area’s status; (2) tighten auto and other mobile source emission standards; (3) require 
reformulated and alternative fuels in the most polluted areas; (4) revise the air toxics section, 
establishing a new program of technology-based standards and addressing the problem of sudden,

catastrophic releases of air toxics; (5) establish an acid rain control program, with a marketable 
allowance scheme to provide flexibility in implementation; (6) require a state-run permit program 
for the operation of major sources of air pollutants; (7) implement the Montreal Protocol to phase 
out most ozone-depleting chemicals; and (8) update the enforcement provisions so that they 
parallel those in other pollution control acts, including authority for EPA to assess administrative 
penalties.

before an appropriation bill can be considered; but this requirement can be waived and frequently 
has been. Thus, while authorization of appropriations in the Clean Air Act (and most other 
environmental statutes) has expired, programs have continued and have been funded. The act’s 
other legal authorities, to issue and enforce regulations, are, for the most part, permanent and are 
not affected by the lack of authorization. 
The remainder of this report describes major programs required by the act, with an emphasis on 
the changes established by the 1990 amendments. 
National Ambient Air Quality Standards 
In Section 109, the act requires EPA to establish National Ambient Air Quality Standards 
(NAAQS) for air pollutants that endanger public health or welfare, in the Administrator’s 
judgment, and whose presence in ambient air results from numerous or diverse sources. The 
NAAQS must be designed to protect public health and welfare with an adequate margin of safety. 
Using this authority, EPA has promulgated NAAQS for six air pollutants: sulfur dioxide (SO2), 
particulate matter (PM2.5 and PM10), nitrogen dioxide (NO2), carbon monoxide (CO), ozone,11 and 
lead. The act requires EPA to review the scientific data upon which the standards are based, and 
revise the standards, if necessary, every five years. More often than not, however, EPA has taken 
more than five years in reviewing and revising the standards. 
Originally, the act required that the NAAQS be attained by 1977 at the latest, but the states 
experienced widespread difficulty in complying with this deadline. As a result, the deadlines for 
achieving NAAQS have been extended several times. Under the 1990 amendments, most areas 
not in attainment with NAAQS must meet special compliance schedules, staggered according to 
the severity of an area’s air pollution problem. The amendments also established specific 
requirements for each nonattainment category, as described below. 
State Implementation Plans 
While the act authorizes the EPA to set NAAQS, the states are responsible for establishing 
procedures to attain and maintain the standards. Under Section 110 of the act, the states adopt 
plans, known as State Implementation Plans (SIPs), and submit them to EPA to ensure that they 
are adequate to meet statutory requirements. 
SIPs are based on emission inventories and computer models to determine whether air quality 
violations will occur. If these data show that standards would be exceeded, the state must impose 
additional controls on existing sources to ensure that emissions do not cause “exceedances” of the 
standards. Proposed new and modified sources must obtain state construction permits in which 
the applicant shows how the anticipated emissions will not exceed allowable limits. In 
nonattainment areas, emissions from new or modified sources must also be offset by reductions in 
emissions from existing sources. 
                                                                  
11 Unlike the other NAAQS pollutants, ozone is not directly emitted, but rather is formed in the atmosphere by the 
interaction of volatile organic compounds (VOCs) and nitrogen oxides (NOx) in the presence of sunlight. The control 
of ozone is, thus, based on regulating emissions of VOCs and NOx. 
Congressional Research Service

Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
The 1990 amendments require EPA to impose sanctions in areas which fail to submit a SIP, fail to 
submit an adequate SIP, or fail to implement a SIP: unless the state corrects such failures, a 2-to-1 
emissions offset for the construction of new polluting sources is imposed 18 months after 
notification to the state, and a ban on most new federal highway grants is imposed six months 
later. An additional ban on air quality grants is discretionary. Ultimately, a Federal 
Implementation Plan may be imposed if the state fails to submit or implement an adequate SIP. 
The amendments also require that, in nonattainment areas, no federal permits or financial 
assistance may be granted for activities that do not “conform” to a State Implementation Plan. 
This requirement can cause a temporary suspension in funding for most new highway and transit 
projects if an area fails to demonstrate that the emissions caused by such projects are consistent 
with attainment and maintenance of ambient air quality standards. Demonstrating conformity of 
transportation plans and SIPs is required in nonattainment areas whenever new plans are 
submitted. 
Nonattainment Requirements 
In a major departure from the prior law, the 1990 Clean Air Act Amendments grouped most 
nonattainment areas into classifications based on the extent to which the NAAQS was exceeded, 
and established specific pollution controls and attainment dates for each classification. These 
requirements are described here as spelled out in Sections 181-193 of the act.12 
Nonattainment areas are classified on the basis of a “design value,” which is derived from the 
pollutant concentration (in parts per million or micrograms per cubic meter) recorded by air 
quality monitoring devices. The design value for the 1-hour ozone standard was the fourth highest 
hourly reading measured during the most recent three-year period. Using these design values, the 
act created five classes of ozone nonattainment, as shown in Table 2. Only Los Angeles fell into 
the “extreme” class, but 97 other areas were classified in one of the other four ozone categories. A 
simpler classification system established moderate and serious nonattainment areas for carbon 
monoxide and particulate matter with correspondingly more stringent control requirements for the 
more polluted class.

12 EPA modified the ozone standard, specified in the statute as 0.12 parts per million (ppm) averaged over a 1-hour 
period, to 0.08 ppm averaged over an 8-hour period, through regulations promulgated in July 1997. In April 2004, the 
agency promulgated an implementation rule for the new 8-hour standard. Under this rule, the 1-hour standard was 
revoked as of June 15, 2005, and areas that had not yet attained it were converted to new classifications depending on 
their 8-hour concentration of ozone. As a result of court challenges, the ramifications of this conversion to the 8-hour 
standard are still unfolding, but in general the former 1-hour nonattainment areas remain subject to the controls 
specified for their 1-hour category. New nonattainment areas that did not exceed the 1-hour standard, but do violate the 
8-hour standard, in general are subject to more flexible controls under Subpart 1 (Sections 171-179B) of the act. The 
standard was revised again in March 2008, to 0.075 ppm averaged over 8 hours, but EPA subsequently agreed to 
reconsider the 2008 standard, a task it expects to complete in 2011. Nonattainment areas for the new standard would be 
designated following its promulgation.

As shown in the table, the deadlines for attainment for ozone nonattainment areas stretched from 
1993 to 2010, depending on the severity of the problem. (Under the 8-hour ozone standard, which 
replaced the 1-hour standard in 2004, these deadlines are changed to 2007 to 2021.) For carbon 
monoxide, the attainment date for moderate areas was December 31, 1995, and for serious areas, 
December 31, 2000. For particulate matter, the deadline for areas designated moderate 
nonattainment as of 1990 was December 31, 1994; for those areas subsequently designated as 
moderate, the deadline is six years after designation. For serious areas, the respective deadlines 
are December 31, 2001, or 10 years after designation. 
Requirements for Ozone Nonattainment Areas 
Although areas with more severe air pollution problems have a longer time to meet the standards, 
more stringent control requirements are imposed in areas with worse pollution. A summary of the 
primary ozone control requirements for each nonattainment category follows. 
Marginal Areas 
•  Inventory emissions sources (to be updated every three years). 
•  Require 1.1 to 1 offsets (i.e., new major emission sources of volatile organic 
compounds [VOCs] must reduce VOC emissions from existing facilities in the 
area by 10% more than the emissions of the new facility). 
•  Impose reasonably available control technology (RACT) on all major sources 
emitting more than 100 tons per year for the nine industrial categories where EPA 
had already issued control technique guidelines describing RACT prior to 1990. 
Moderate Areas 
•  Meet all requirements for marginal areas. 
•  Impose a 15% reduction in VOC emissions in six years. 
•  Adopt a basic vehicle inspection and maintenance program. 
•  Impose RACT on all major sources emitting more than 100 tons per year for all 
additional industrial categories where EPA will issue control technique guidelines 
describing RACT. 
•  Require vapor recovery at gas stations selling more than 10,000 gallons per 
month. 
•  Require 1.15 to 1 offsets. 
Serious Areas 
•  Meet all requirements for moderate areas. 
Congressional Research Service 
7 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
•  Reduce definition of a major source of VOCs from emissions of 100 tons per 
year to 50 tons per year for the purpose of imposing RACT. 
•  Reduce VOCs 3% annually for years 7 to 9 after the 15% reduction already 
required by year 6. 
•  Improve monitoring. 
•  Adopt an enhanced vehicle inspection and maintenance program. 
•  Require fleet vehicles to use clean alternative fuels. 
•  Adopt transportation control measures if the number of vehicle miles traveled in 
the area is greater than expected. 
•  Require 1.2 to 1 offsets. 
•  Adopt contingency measures if the area does not meet required VOC reductions. 
Severe Areas 
•  Meet all requirements for serious areas. 
•  Reduce definition of a major source of VOCs from emissions of 50 tons per year 
to 25 tons per year for the purpose of imposing RACT. 
•  Adopt specified transportation control measures. 
•  Implement a reformulated gasoline program. 
•  Require 1.3 to 1 offsets. 
•  Impose $5,000 per ton penalties on major sources if the area does not meet 
required reductions. 
Extreme Areas 
•  Meet all requirements for severe areas. 
•  Reduce definition of a major source of VOCs from emissions of 25 tons per year 
to 10 tons per year for the purpose of imposing RACT. 
•  Require clean fuels or advanced control technology for boilers emitting more 
than 25 tons per year of NOx. 
•  Require 1.5 to 1 offsets. 
As noted, EPA promulgated a new, 8-hour ozone standard in July 1997. Following extensive court 
challenges, the agency designated nonattainment areas for the new standard on April 30, 2004. 
State Implementation Plans were required to be submitted in 2007. 
Requirements for Carbon Monoxide Nonattainment Areas 
As with ozone nonattainment areas, carbon monoxide (CO) nonattainment areas are subjected to 
specified control requirements, with more stringent requirements in Serious nonattainment areas. 
A summary of the primary CO control requirements for each nonattainment category follows. 
Moderate Areas 
Congressional Research Service

Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
•  Conduct an inventory of emissions sources. 
•  Forecast total vehicle miles traveled in the area. 
•  Adopt an enhanced vehicle inspection and maintenance program. 
•  Demonstrate annual improvements sufficient to attain the standard. 
Serious Areas 
•  Adopt specified transportation control measures. 
•  Implement an oxygenated fuels program for all vehicles in the area. 
•  Reduce definition of a major source of CO from emissions of 100 tons per year 
to 50 tons per year if stationary sources contribute significantly to the CO 
problem. 
Serious areas failing to attain the standard by the deadline have to revise their SIP and 
demonstrate reductions of 5% per year until the standard is attained. 
Requirements for Particulate Nonattainment Areas 
Particulate (PM10) nonattainment areas are also subject to specified control requirements. These 
are: 
Moderate Areas 
•  Require permits for new and modified major stationary sources of PM10. 
•  Impose reasonably available control measures (RACM). 
Serious Areas 
•  Impose best available control measures (BACM). 
•  Reduce definition of a major source of PM10 from 100 tons per year to 70 tons 
per year. 
In July 1997, EPA promulgated new standards for fine particulates (PM2.5). The PM2.5 standards 
were also subject to court challenges. The absence of a monitoring network capable of measuring 
the pollutant delayed implementation as well. Nonattainment areas for PM2.5 were designated on 
April 14, 2005. States had three years subsequent to designation to submit State Implementation 
Plans. Revisions to the NAAQS promulgated in October 2006 strengthened the PM2.5 standard. 
Transported Air Pollution 
Meeting the nation’s clean air standards can be complicated as air pollution is no respecter of 
political boundaries or subdivisions. This problem of transported air pollutants has come into 
particular focus as states and EPA attempt to develop effective compliance strategies to achieve 
both the ozone and the PM2.5 NAAQS. Under Section 110(a)(2)(D), SIPs must include adequate 
provisions to prevent sources within that state from contributing significantly to nonattainment in 
one or more downwind states. 
Congressional Research Service

Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
If EPA finds a SIP inadequate to achieve a NAAQS, it must require the affected state to submit a 
revised SIP that includes sufficient measures to bring that state into compliance. This is known as 
a "SIP Call.” The 1990 Clean Air Act amendments provided EPA and the states with new tools to 
address the transport problem through this provision. One of those tools is Section 176A, a 
provision that permits the EPA, either on its own or by petition from any state, to establish a 
transport region to address regional pollution problems contributing to violations of a primary 
NAAQS. A commission of EPA and state officials is constituted to make recommendations to 
EPA on appropriate mitigation strategies. Based on the commission’s findings and 
recommendations, EPA is then required under Section 110(k)(5) to notify affected states of 
inadequacies in their current state implementation plans and to establish deadlines (not to exceed 
18 months) for submitting necessary revisions (i.e., a SIP call). Besides authorizing 
administratively created transport regions, the 1990 amendments statutorily created an Ozone 
Transport Region (OTR) in the Northeast. This provision (Section 184 of the act) required 
specific additional controls for all areas (not only nonattainment areas) in that region, and 
established the Ozone Transport Commission for the purpose of recommending to EPA 
regionwide controls affecting all areas in the region. 
The transport issue may also be addressed by affected downwind states through a Section 126 
petition. As amended by the 1990 Clean Air Act amendments, under Section 126(b) any state or 
political subdivision may petition EPA for a finding that a major source or group of stationary 
sources located in another state is emitting pollutants that "significantly contribute" to the 
nonattainment of a NAAQS by their state. EPA is to respond to the petition within 60 days. If the 
petition is granted, the offending sources must cease operations within three months unless the 
sources comply with emission controls and the compliance schedules as determined by EPA to 
bring them into compliance with the section. Section 126 has rarely been used, although it has 
proven useful to EPA in some cases as backup authority where there might be challenges to a SIP 
call. 
Emission Standards for Mobile Sources 
Title II of the Clean Air Act has required emission standards for automobiles since 1968. The 
1990 amendments significantly tightened these standards: for cars, the hydrocarbon standard was 
reduced by 40% and the nitrogen oxides (NOx) standard by 50%. These standards—referred to as 
“Tier 1” standards—were phased in over the 1994-1996 model years. 
The amendments envisioned a further set of reductions (“Tier 2” standards), but not before model 
year 2004. For Tier 2 standards to be promulgated, the agency was first required to report to 
Congress concerning the need for further emission reductions, the availability of technology to 
achieve such reductions, and the cost-effectiveness of such controls compared to other means of 
attaining air quality standards. EPA submitted this report to Congress in August 1998, concluding 
that further emission reductions were needed and that technology to achieve such reductions was 
available and cost-effective. Tier 2 standards, requiring emission reductions of 77% to 95% from 
cars and light trucks were promulgated in February 2000, and were phased in over the 2004-2009 
model years. To facilitate the use of more effective emission controls, the standards also require a 
more than 90% reduction in the sulfur content of gasoline, beginning in 2004. 
The 1990 amendments also required that oxygenated gasoline, designed to reduce emissions of 
carbon monoxide, be sold in the worst CO nonattainment areas and that “reformulated” gasoline 
(RFG), designed to reduce emissions of volatile organic compounds and toxic air pollutants, be 
sold in the nine worst ozone nonattainment areas (Los Angeles, San Diego, Houston, Baltimore, 
Congressional Research Service 
10 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
Philadelphia, New York, Hartford, Chicago, and Milwaukee); metropolitan Washington, DC, and 
four areas in California were added to the mandatory list later. Other ozone nonattainment areas 
can opt in to the RFG program; as of 2006, additional areas in 11 states had done so. 
The fuels provisions were modified by the Energy Policy Act of 2005 (EPACT), removing the 
requirement that RFG contain oxygenates. Instead, EPACT required the use of increasing 
amounts of renewable fuel, most likely to be ethanol, in motor fuels, beginning in 2006. The 
Energy Independence and Security Act of 2007 further strengthened the renewable fuel 
requirements. 
Use of alternative fuels and development of cleaner engines was also to be stimulated by the 
Clean-Fuel Fleet Program. In all of the most seriously polluted ozone and CO nonattainment 
areas, centrally fueled fleets of 10 or more passenger cars and light-duty trucks must purchase at 
least 30% clean-fuel vehicles when they add new vehicles to existing fleets, starting in 1999. (The 
act originally required the program to begin in 1998, but the start was delayed by a year.) The 
percentage rose to 50% in 2000 and 70% in 2001. Heavy-duty fleets are required to purchase at 
least 50% clean-fuel vehicles annually. A clean fuel vehicle is one which meets Low Emission 
Vehicle (LEV) standards and operates on reformulated gasoline, reformulated diesel, methanol, 
ethanol, natural gas, liquefied petroleum gas, hydrogen, or electricity. 
In addition to the above program, California’s Zero Emission Vehicle (ZEV) program also is 
intended to promote the development of alternative fuels and vehicles. Section 209(b) of the 
Clean Air Act allows the EPA Administrator to grant California the authority to develop its own 
vehicle emissions standards if those standards are at least as stringent as the federal standards and 
if the state demonstrates that it needs the standards to meet compelling and extraordinary 
conditions. In addition to setting more stringent standards for all vehicles, California used this 
authority to establish a program requiring auto manufacturers to sell ZEVs (electric or hydrogen 
fuel cell vehicles) in the state beginning in 2003. This program has been substantially modified 
since it was enacted, and now allows credit for hybrid and partial ZEV vehicles in addition to true 
ZEVs, but it has served as an incubator for lower emission technologies since its adoption. 
Section 177 of the act allows other states to adopt California’s stricter standards: at least 10 states 
(Connecticut, Maine, Massachusetts, New Jersey, New York, Oregon, Pennsylvania, Rhode 
Island, Vermont, and Washington) have already adopted them or are in the process of doing so. 
The 1990 amendments also imposed tighter requirements on certification (an auto’s useful life is 
defined as 100,000 miles instead of the earlier 50,000 miles), on emissions allowed during 
refueling, on low temperature CO emissions, on in-use performance over time, and on warranties 
for the most expensive emission control components (8 years/80,000 miles for the catalytic 
converter, electronic emissions control unit, and onboard emissions diagnostic unit). Regulations 
were also extended to include nonroad fuels and engines. 
Standards for trucks and buses using diesel engines were also strengthened. The 1990 
amendments required new urban buses to reduce emissions of diesel particulates 92% by 1996, 
and all other heavy-duty diesel engines to achieve an 83% reduction by the same year. NOx 
emissions must also be reduced, 33% by 1998. Authority to further strengthen these standards led 
to promulgation in January 2001 of new emission standards requiring a further 90%-95% 
reduction in emissions phased in over the 2007-2010 model years, and a reduction of 97% in the 
allowable amount of sulfur in highway diesel fuel. These regulations were followed in May 2004 
by similar requirements for nonroad diesel equipment, which will be phased in between 2007 and 
2015.

Hazardous Air Pollutants 
Completely rewritten by the Clean Air Act Amendments of 1990, Section 112 of the act 
establishes programs for protecting public health and the environment from exposure to toxic air 
pollutants. As revised by the 1990 amendments, the section contains four major provisions: 
Maximum Achievable Control Technology (MACT) requirements; health-based standards; 
standards for stationary “area sources” (small, but numerous sources, such as gas stations or dry 
cleaners, that collectively emit significant quantities of hazardous pollutants); and requirements 
for the prevention of catastrophic releases. 
First, EPA is to establish technology-based emission standards, called MACT standards, for 
sources of 187 pollutants listed in the legislation, and to specify categories of sources subject to 
the emission standards.13 EPA is to revise the standards periodically (at least every eight years). 
EPA can, on its own initiative or in response to a petition, add or delete substances or source 
categories from the lists. 
Section 112 establishes a presumption in favor of regulation for the designated chemicals; it 
requires regulation of a designated pollutant unless EPA or a petitioner is able to show “that there 
is adequate data on the health and environmental effects of the substance to determine that 
emissions, ambient concentrations, bioaccumulation or deposition of the substance may not 
reasonably be anticipated to cause any adverse effects to human health or adverse environmental 
effects.” 
EPA is required to set standards for sources of the listed pollutants that achieve “the maximum 
degree of reduction in emissions” taking into account cost and other non-air-quality factors. 
These MACT standards for new sources “shall not be less stringent than the most stringent 
emissions level that is achieved in practice by the best controlled similar source.” The standards 
for existing sources may be less stringent than those for new sources, but must be no less 
stringent than the emission limitations achieved by either the best performing 12% of existing 
sources (if there are more than 30 such sources in the category or subcategory) or the best 
performing 5 similar sources (if there are fewer than 30). Existing sources are given three years 
following promulgation of standards to achieve compliance, with a possible one-year extension; 
additional extensions may be available for special circumstances or for certain categories of 
sources. Existing sources that achieve voluntary early emissions reductions will receive a six-year 
extension for compliance with MACT. 
The second major provision of Section 112 directs EPA to set health-based standards to address 
situations in which a significant residual risk of adverse health effects or a threat of adverse 
environmental effects remains after installation of MACT. This provision requires that EPA, after 
consultation with the Surgeon General of the United States, submit a report to Congress on the 
public health significance of residual risks, and recommend legislation regarding such risks. If 
Congress does not legislate in response to EPA’s recommendations, then EPA is required to issue 
standards for categories of sources of hazardous air pollutants as necessary to protect the public 
health with an ample margin of safety or to prevent an adverse environmental effect. A residual 
risk standard is required for any source emitting a cancer-causing pollutant that poses an added 
                                                                  
13 The 1990 amendments specified 189 pollutants, but P.L. 102-187, enacted on December 4, 1991, deleted hydrogen 
sulfide from the list of toxic pollutants, leaving only 188. On December 19, 2005, EPA removed methyl ethyl ketone 
(MEK) from the list of toxic air pollutants. The total number of listed air toxics is now 187. 
Congressional Research Service 
12 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
risk to the most exposed person of more than one-in-a-million. Residual risk standards are due 
eight years after promulgation of MACT for the affected source category. Existing sources have 
90 days to comply with a residual risk standard, with a possible two-year extension. In general, 
residual risk standards do not apply to area sources. 
The law directed EPA to contract with the National Academy of Sciences (NAS) for a study of 
risk assessment methodology, and created a Risk Assessment and Management Commission to 
investigate and report on policy implications and appropriate uses of risk assessment and risk 
management. In 1994 NAS published its report, Science and Judgment in Risk Assessment. The 
Commission study, Framework for Environmental Health Risk Management, was released in 
1997. 
Third, in addition to the technology-based and health-based programs for major sources of 
hazardous air pollution, EPA is to establish standards for stationary “area sources” determined to 
present a threat of adverse effects to human health or the environment. The provision requires 
EPA to regulate the stationary area sources responsible for 90% of the emissions of the 30 
hazardous air pollutants that present the greatest risk to public health in the largest number of 
urban areas. In setting the standard, EPA can impose less stringent “generally available” control 
technologies, rather than MACT. 
Finally, Section 112 addresses prevention of sudden, catastrophic releases of air toxics by 
establishing an independent Chemical Safety and Hazard Investigation Board. The Board is 
responsible for investigating accidents involving releases of hazardous substances, conducting 
studies, and preparing reports on the handling of toxic materials and measures to reduce the risk 
of accidents. 
EPA is also directed to issue prevention, detection, and correction requirements for catastrophic 
releases of air toxics by major sources. Section 112(r) requires owners and operators to prepare 
risk management plans including hazard assessments, measures to prevent releases, and a 
response program. 
New Source Performance Standards 
Section 111 of the act requires EPA to establish nationally uniform, technology-based standards 
(called New Source Performance Standards, or NSPS) for categories of new industrial facilities. 
These standards accomplish two goals: first, they establish a consistent baseline for pollution 
control that competing firms must meet, and thereby remove any incentive for states or 
communities to weaken air pollution standards in order to attract polluting industry; and second, 
they preserve clean air to accommodate future growth, as well as for its own benefits. 
NSPS establish maximum emission levels for new major stationary sources—powerplants, steel 
mills, and smelters, for example—with the emission levels determined by the best “adequately 
demonstrated” continuous control technology available, taking costs into account. EPA must 
regularly revise and update NSPS applicable to designated sources as new technology becomes 
available, since the goal is to prevent new pollution problems from developing and to force the 
installation of new control technology. 
The standards also apply to modifications of existing facilities, through a process called New 
Source Review (NSR). The law’s ambiguity regarding what constitutes a modification (subject to 
Congressional Research Service 
13 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
NSR) as opposed to routine maintenance of a facility has led to litigation, with EPA proposing in 
recent years to modify its interpretation of the requirements of this section. 
Solid Waste Incinerators 
Prior to 1990, solid waste incinerators, which emit a wide range of pollutants, were subject to 
varying degrees of state and federal regulation depending on their size, age, and the type of waste 
burned. In a new Section 129, the 1990 amendments established more consistent federal 
requirements specifying that emissions of 10 categories of pollutants be regulated at new and 
existing incinerators burning municipal solid waste, medical waste, and commercial and 
industrial waste. The amendments also established emissions monitoring and operator training 
requirements. 
Prevention of Significant Deterioration / Regional Haze 
Sections 160-169 of the act establish requirements for the prevention of significant deterioration 
of air quality (PSD). The PSD program reflects the principle that areas where air quality is better 
than that required by NAAQS should be protected from significant new air pollution even if 
NAAQS would not be violated. 
The act divides clean air areas into three classes, and specifies the increments of SO2 and 
particulate pollution allowed in each. Class I areas include international and national parks, 
wilderness and other pristine areas; allowable increments of new pollution are very small. Class II 
areas include all attainment and not classifiable areas, not designated as Class I; allowable 
increments of new pollution are modest. Class III represents selected areas that states may 
designate for development; allowable increments of new pollution are large (but not exceeding 
NAAQS). Through an elaborate hearing and review process, a state can have regions redesignated 
from Class II to Class III (although none have yet been so redesignated). 
While the 1977 amendments only stipulated PSD standards for two pollutants, SO2 and 
particulates, EPA is supposed to establish standards for other criteria pollutants. Thus far, only 
one of the other four (NO2) has been addressed: the agency promulgated standards for NO2 in 
1988. 
Newly constructed polluting sources in PSD areas must install best available control technology 
(BACT) that may be more strict than that required by NSPS. The justifications of the policy are 
that it protects air quality, provides an added margin of health protection, preserves clean air for 
future development, and prevents firms from gaining a competitive edge by “shopping” for clean 
air to pollute. 
In Sections 169A and B, the act also sets a national goal of preventing and remedying impairment 
of visibility in national parks and wilderness areas, and requires EPA to promulgate regulations to 
assure reasonable progress toward that goal. In the 1990 Amendments, Congress strengthened 
these provisions, which had not been implemented. 
The amendments required EPA to establish a Grand Canyon Visibility Transport Commission, 
composed of governors from each state in the affected region, an EPA designee, and a 
representative of each of the national parks or wilderness areas in the region. Other visibility 
transport commissions can be established upon EPA’s discretion or upon petition from at least two 
Congressional Research Service 
14 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
states. Within 18 months of receiving a report from one of these commissions, EPA is required to 
promulgate regulations to assure reasonable progress toward the visibility goal, including 
requirements that states update their State Implementation Plans to contain emission limits, 
schedules of compliance, and other measures necessary to make reasonable progress. Specifically 
mentioned is a requirement that states impose Best Available Retrofit Technology on existing 
sources of emissions impairing visibility. 
The Grand Canyon Commission delivered a set of recommendations to EPA in June 1996, and the 
agency subsequently promulgated a “regional haze” program applicable to all 50 states under this 
authority. 
Acid Deposition Control 
The Clean Air Act Amendments of 1990 added an acid deposition control program (Title IV) to 
the act. It set goals for the year 2000 of reducing annual SO2 emissions by 10 million tons from 
1980 levels and reducing annual NOx emissions by 2 million tons, also from 1980 levels. 
The SO2 reductions were imposed in two steps. Under Phase 1, owners/operators of 111 electric 
generating facilities listed in the law that are larger than 100 megawatts had to meet tonnage 
emission limitations by January 1, 1995. This would reduce SO2 emission by about 3.5 million 
tons. Phase 2 included facilities larger than 75 megawatts, with a deadline of January 1, 2000. 
Compliance has been 100%. 
To introduce some flexibility in the distribution and timing of reductions, the act creates a 
comprehensive permit and emissions allowance system. An allowance is a limited authorization 
to emit a ton of SO2. Issued by EPA, the allowances would be allocated to Phase 1 and Phase 2 
units in accordance with baseline emissions estimates. Powerplants which commence operation 
after November 15, 1990, would not receive any allowances. These new units would have to 
obtain allowances (offsets) from holders of existing allowances. Allowances may be traded 
nationally during either phase. The law also permitted industrial sources and powerplants to sell 
allowances to utility systems under regulations developed by EPA. Allowances may be banked by 
a utility for future use or sale. 
The act provided for two types of sales to improve the liquidity of the allowance system and to 
ensure the availability of allowances for utilities and independent power producers who need 
them. First, a special reserve fund consisting of 2.8% of Phase 1 and Phase 2 allowance 
allocations has been set aside for sale. Allowances from this fund (25,000 annually from 1993-
1999 and 50,000 thereafter) are sold at a fixed price of $1,500 an allowance. Independent power 
producers have guaranteed rights to these allowances under certain conditions. Second, an annual, 
open auction sold allowances (150,000 from 1993-1995, and 250,000 from 1996-1999) with no 
minimum price. Utilities with excess allowances may have them auctioned off at this auction, and 
any person may buy allowances. 
The act essentially caps SO2 emissions at individual existing sources through a tonnage 
limitation, and at future plants through the allowance system. First, emissions from most existing 
sources are capped at a specified emission rate times an historic baseline level. Second, for plants 
commencing operation after November 15, 1990, emissions must be completely offset with 
additional reductions at existing facilities beginning after Phase 2 compliance. However, as noted 
above, the law provides some allowances to future powerplants which meet certain criteria. The 
utility SO2 emission cap was set at 8.9 million tons, with some exceptions. 
Congressional Research Service 
15 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
The act provides that if an affected unit does not have sufficient allowances to cover its 
emissions, it is subject to an excess emission penalty of $2,000 per ton of SO2 and required to 
reduce an additional ton of SO2 the next year for each ton of excess pollutant emitted. 
The act also requires EPA to inventory industrial emissions of SO2 and to report every five years, 
beginning in 1995. If the inventory shows that industrial emissions may reach levels above 5.60 
million tons per year, then EPA is to take action under the act to ensure that the 5.60 million ton 
cap is not exceeded. 
The act requires EPA to set specific NOx emission rate limitations—0.45 lb. per million Btu for 
tangentially-fired boilers and 0.50 lb. per million Btu for wall-fired boilers—unless those rates 
can not be achieved by low-NOx burner technology. Tangentially and wall-fired boilers affected 
by Phase 1 SO2 controls must also meet NOx requirements. EPA was to set emission limitations 
for other types of boilers by 1997 based on low-NOx burner costs, which EPA did. In addition, 
EPA was to propose and promulgate a revised new source performance standard for NOx from 
fossil fuel steam generating units, which EPA also did, in 1998. 
Permits 
The Clean Air Act Amendments of 1990 added a Title V to the act which requires states to 
administer a comprehensive permit program for the operation of sources emitting air pollutants. 
These requirements are modeled after similar provisions in the Clean Water Act. Previously, the 
Clean Air Act contained limited provision for permits, requiring only new or modified major 
stationary sources to obtain construction permits (under Section 165 of the act). 
Sources subject to the permit requirements generally include major sources that emit or have the 
potential to emit 100 tons per year of any regulated pollutant, plus stationary and area sources that 
emit or have potential to emit lesser specified amounts of hazardous air pollutants. However, in 
nonattainment areas, the permit requirements also include sources which emit as little as 50, 25, 
or 10 tons per year of VOCs, depending on the severity of the region’s nonattainment status 
(serious, severe, or extreme). 
States were required to develop permit programs and to submit those programs for EPA approval 
by November 15, 1993. EPA had one year to approve or disapprove a state’s submission in whole 
or in part. After the effective date of a state plan, sources had 12 months to submit an actual 
permit application. 
States are to collect annual fees from sources sufficient to cover the “reasonable costs” of 
administering the permit program, with revenues to be used to support the agency’s air pollution 
control program. The fee must be at least $25 per ton of regulated pollutants (excluding carbon 
monoxide). Permitting authorities have discretion not to collect fees on emissions in excess of 
4,000 tons per year and may collect other fee amounts, if appropriate. 
The permit states how much of which air pollutants a source is allowed to emit. As a part of the 
permit process, a source must prepare a compliance plan and certify compliance. The term of 
permits is limited to no more than five years; sources are required to renew permits at that time. 
State permit authorities must notify contiguous states of permit applications that may affect them; 
the application and any comments of contiguous states must be forwarded to EPA for review. EPA 
can veto a permit; however, this authority is essentially limited to major permit changes. EPA 
review need not include permits which simply codify elements of a state’s overall clean air plan, 
Congressional Research Service 
16 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
and EPA has discretion to not review permits for small sources. Holding a permit to some extent 
shields a source from enforcement actions: the act provides that a source cannot be held in 
violation if it is complying with explicit requirements addressed in a permit, or if the state finds 
that certain provisions do not apply to that source. 
Enforcement 
Section 113 of the act, which was also strengthened by the 1990 amendments, covers 
enforcement. The section establishes federal authority to issue agency and court orders requiring 
compliance and to impose penalties for violations of act requirements. Section 114 authorizes 
EPA to require sources to submit reports, monitor emissions, and certify compliance with the act’s 
requirements, and authorizes EPA personnel to conduct inspections. 
Like most federal environmental statutes, the Clean Air Act is enforced primarily by states or 
local governments; they issue most permits, monitor compliance, and conduct the majority of 
inspections. The federal government functions as a backstop, with authority to review state 
actions. The agency may act independently or may file its own enforcement action in cases where 
it concludes that a state’s response was inadequate. 
The act also provides for citizen suits both against persons (including corporations or government 
agencies) alleged to have violated emissions standards or permit requirements, and against EPA in 
cases where the Administrator has failed to perform an action that is not discretionary under the 
act. Citizen groups have often used the latter provision to compel the Administrator to promulgate 
regulations required by the statute. 
The 1990 Amendments elevated penalties for some knowing violations from misdemeanors to 
felonies; removed the ability of a source to avoid an enforcement order or civil penalty by ceasing 
a violation within 60 days of notice; gave authority to EPA to assess administrative penalties; and 
authorized $10,000 awards to persons supplying information leading to convictions under the act. 
Stratospheric Ozone Protection 
Title VI of the 1990 Clean Air Act Amendments represents the United States’ primary response on 
the domestic front to the ozone depletion issue. It also implements the U.S. international 
responsibilities under the Montreal Protocol on Substances that Deplete the Ozone Layer (and its 
amendments). Indeed, Section 606(a)(3) provides that the Environmental Protection Agency shall 
adjust phase-out schedules for ozone-depleting substances in accordance with any future changes 
in Montreal Protocol schedules. As a result, the phase-out schedules contained in Title VI for 
various ozone-depleting compounds have now been superseded by subsequent amendments to the 
Montreal Protocol. 
Since passage of Title VI, depleting substances such as CFCs, methyl chloroform, carbon 
tetrachloride, and halons (referred to as Class 1 substances) have been phased out by industrial 
countries, including the United States. New uses of hydrochlorofluorocarbons (HCFCs) (called 
Class 2 substances under Title VI) are banned beginning January 1, 2015, unless the HCFCs are 
recycled, used as a feedstock, or used as a refrigerant for appliances manufactured prior to 
January 1, 2020. Production of HCFCs is to be frozen January 1, 2015, and phased out by January 
1, 2030. Exemptions consistent with the Montreal Protocol are allowed. 
Congressional Research Service 
17 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
The EPA is required to add any substance with an ozone depletion potential (ODP) of 0.2 or 
greater to the list of Class 1 substances and set a phase-out schedule of no more than seven years. 
For example, methyl bromide (ODP estimated by EPA at 0.7) was added to the list in December 
1993, requiring its phaseout by January 1, 2001; this decision was altered by Congress in 1998 to 
harmonize the U.S. methyl bromide phase-out schedule with the 2005 deadline set by the parties 
to the Montreal Protocol in 1997. Also, EPA is required to add any substance that is known or 
may be reasonably anticipated to harm the stratosphere to the list of Class 2 substances and set a 
phase-out schedule of no more than 10 years. 
Title VI contains several implementing strategies to avoid releases of ozone-depleting chemicals 
to the atmosphere, including (1) for Class 1 substances used as refrigerant—lowest achievable 
level of use and emissions, maximum recycling, and safe disposal required by July 1, 1992; (2) 
for servicing or disposing refrigeration equipment containing Class 1 and 2 substances—venting 
banned as of July 1, 1992; (3) for motor vehicle air conditioners containing Class 1 or 2 
substances—recycling required by January 1, 1992 (smaller shops by January 1, 1993); (4) sale of 
small containers of class 1 and 2 substances—banned within two years of enactment; and (5) 
nonessential products—banned within two years of enactment.

Clean Water Act14 
The principal law governing pollution of the nation’s surface waters is the Federal Water 
Pollution Control Act, or Clean Water Act. Originally enacted in 1948, it was totally revised by 
amendments in 1972 that gave the act its current shape. The 1972 legislation spelled out 
ambitious programs for water quality improvement that have since been expanded and are still 
being implemented by industries and municipalities. Congress made certain fine-tuning 
amendments in 1977, revised portions of the law in 1981, and enacted further amendments in 
1987. Table 4 lists the original law and major amendments to it.

Background 
The Federal Water Pollution Control Act of 1948 was the first comprehensive statement of federal 
interest in clean water programs, and it specifically provided state and local governments with 
technical assistance funds to address water pollution problems, including research. Water 
pollution was viewed as primarily a state and local problem, hence, there were no federally 
required goals, objectives, limits, or even guidelines. When it came to enforcement, federal 
involvement was strictly limited to matters involving interstate waters and only with the consent 
of the state in which the pollution originated. 
During the latter half of the 1950s and well into the 1960s, water pollution control programs were 
shaped by four laws which amended the 1948 statute. They dealt largely with federal assistance to

municipal dischargers and with federal enforcement programs for all dischargers. During this 
period, the federal role and federal jurisdiction were gradually extended to include navigable 
intrastate, as well as interstate, waters. Water quality standards became a feature of the law in 
1965, requiring states to set standards for interstate waters that would be used to determine actual 
pollution levels. 
By the late 1960s, there was a widespread perception that existing enforcement procedures were 
too time-consuming and that the water quality standards approach was flawed because of 
difficulties in linking a particular discharger to violations of stream quality standards. 
Additionally, there was mounting frustration over the slow pace of pollution cleanup efforts and a 
suspicion that control technologies were being developed but not applied to the problems. These 
perceptions and frustrations, along with increased public interest in environmental protection, set 
the stage for the 1972 amendments. 
The 1972 statute did not continue the basic components of previous laws as much as it set up new 
ones. It set optimistic and ambitious goals, required all municipal and industrial wastewater to be 
treated before being discharged into waterways, increased federal assistance for municipal 
treatment plant construction, strengthened and streamlined enforcement, and expanded the federal 
role while retaining the responsibility of states for day-to-day implementation of the law. 
The 1972 legislation declared as its objective the restoration and maintenance of the chemical, 
physical, and biological integrity of the nation’s waters. Two goals also were established: zero 
discharge of pollutants by 1985 and, as an interim goal and where possible, water quality that is 
both “fishable” and “swimmable” by mid-1983. While those dates have passed, the goals remain, 
and efforts to attain the goals continue. 
The Clean Water Act (CWA) today consists of two major parts, one being the Title II and Title VI 
provisions which authorize federal financial assistance for municipal sewage treatment plant 
construction. The other is regulatory requirements, found throughout the act, that apply to 
industrial and municipal dischargers. 
The act has been termed a technology-forcing statute because of the rigorous demands placed on 
those who are regulated by it to achieve higher and higher levels of pollution abatement. 
Industries were given until July 1, 1977, to install “best practicable control technology” (BPT) to 
clean up waste discharges. Municipal wastewater treatment plants were required to meet an 
equivalent goal, termed “secondary treatment,” by that date. (Municipalities unable to achieve 
secondary treatment by that date were allowed to apply for case-by-case extensions up to July 1, 
1988. According to EPA, 86% of all cities met the 1988 deadline; the remainder were put under 
judicial or administrative schedules requiring compliance as soon as possible. However, many 
cities, especially smaller ones, continue to make investments in building or upgrading facilities 
needed to achieve secondary treatment.) Cities that discharge wastes into marine waters were 
eligible for case-by-case waivers of the secondary treatment requirement, where sufficient 
showing could be made that natural factors provide significant elimination of traditional forms of 
pollution and that both balanced populations of fish, shellfish, and wildlife and water quality 
standards would be protected. 
The primary focus of BPT was on controlling discharges of conventional pollutants, such as 
suspended solids, biochemical oxygen demanding material, fecal coliform and bacteria, and pH. 
These pollutants are substances that are biodegradable (i.e., bacteria can break them down), occur

naturally in the aquatic environment, and deplete the dissolved oxygen concentration in water, 
which is necessary for fish and other aquatic life. 
The act required greater pollutant cleanup than BPT by no later than March 31, 1989, generally 
demanding that industry use the “best available technology” (BAT) that is economically 
achievable. Compliance extensions of as long as two years are available for industrial sources 
utilizing innovative or alternative technology. Failure to meet statutory deadlines could lead to 
enforcement action. 
The act utilizes both water quality standards and technology-based effluent limitations to protect 
water quality. Technology-based effluent limitations are specific numerical limitations established 
by EPA and placed on certain pollutants from certain sources. They are applied to industrial and 
municipal sources through numerical effluent limitations in discharge permits. Water quality 
standards are standards for the overall quality of water. They consist of the designated beneficial 
use or uses of a waterbody (recreation, water supply, industrial, or other), plus a numerical or 
narrative statement identifying maximum concentrations of various pollutants which would not 
interfere with the designated use. The act requires each state to establish water quality standards 
for all bodies of water in the state. These standards serve as the backup to federally set 
technology-based requirements by indicating where additional pollutant controls are needed to 
achieve the overall goals of the act. In waters where industrial and municipal sources have 
achieved technology-based effluent limitations, yet water quality standards have not been met, 
dischargers may be required to meet additional pollution control requirements. For each of these 
waters, the act requires states to set a total maximum daily load (TMDL) of pollutants at a level 
that ensures that applicable water quality standards can be attained and maintained. A TMDL is 
both a planning process for attaining water quality standards and a quantitative assessment of 
pollution problems, sources, and pollutant reductions needed to restore and protect a river, stream, 
or lake. Based on state reports, EPA estimates that more than 40,000 U.S. waters are impaired and 
require preparation of TMDLs. 
Control of toxic pollutant discharges has been a key focus of water quality programs. In addition 
to the BPT and BAT national standards, states are required to implement control strategies for 
waters expected to remain polluted by toxic chemicals even after industrial dischargers have 
installed the best available cleanup technologies required under the law. Development of 
management programs for these post-BAT pollutant problems was a prominent element in the 
1987 amendments and is a key continuing aspect of CWA implementation. 
Prior to the 1987 amendments, programs in the Clean Water Act were primarily directed at point-
source pollution—wastes discharged from discrete and identifiable sources, such as pipes and 
other outfalls. In contrast, except for general planning activities, little attention had been given to 
nonpoint-source pollution (stormwater runoff from agricultural lands, forests, construction sites, 
and urban areas), despite estimates that it represents more than 50% of the nation’s remaining 
water pollution problems. As it travels across land surface towards rivers and streams, rainfall and 
snowmelt runoff picks up pollutants, including sediments, toxic materials, and conventional 
wastes (e.g., nutrients) that can degrade water quality. 
The 1987 amendments authorized measures to address such pollution by directing states to 
develop and implement nonpoint pollution management programs (Section 319 of the act). States 
were encouraged to pursue groundwater protection activities as part of their overall nonpoint 
pollution control efforts. Federal financial assistance was authorized to support demonstration

projects and actual control activities. These grants may cover up to 60% of program 
implementation costs. 
While the act imposes great technological demands, it also recognizes the need for 
comprehensive research on water quality problems. This is provided throughout the statute, on 
topics including pollution in the Great Lakes and Chesapeake Bay, in-place toxic pollutants in 
harbors and navigable waterways, and water pollution resulting from mine drainage. The act also 
authorizes support to train personnel who operate and maintain wastewater treatment facilities. 
Federal and State Responsibilities 
Under this act, federal jurisdiction is broad, particularly regarding establishment of national 
standards or effluent limitations. The Environmental Protection Agency (EPA) issues regulations 
containing the BPT and BAT effluent standards applicable to categories of industrial sources 
(such as iron and steel manufacturing, organic chemical manufacturing, petroleum refining, and 
others). Certain responsibilities are delegated to the states, and this act, like other environmental 
laws, embodies a philosophy of federal-state partnership in which the federal government sets the 
agenda and standards for pollution abatement, while states carry out day-to-day activities of 
implementation and enforcement. Delegated responsibilities under the act include authority for 
qualified states to issue discharge permits to industries and municipalities and to enforce permits 
(46 states have been delegated the permit program; EPA issues discharge permits in the remaining 
states—Idaho, Massachusetts, New Hampshire, New Mexico—and the District of Columbia.). In 
addition, as noted above, states are responsible for establishing water quality standards. 
Titles II and VI—Municipal Wastewater Treatment Construction 
Federal law has authorized grants for planning, design, and construction of municipal sewage 
treatment facilities since 1956 (Act of July 9, 1956, or P.L. 84-660). Congress greatly expanded 
this grant is program in 1972. Since that time Congress has authorized $65 billion and 
appropriated more than $85 billion in Clean Water Act funds to aid wastewater infrastructure 
plant construction (not including congressionally earmarked appropriations for specific projects). 
Grants are allocated among the states according to a complex statutory formula that combines two 
factors: state population and an estimate of municipal sewage treatment funding needs derived 
from a biennial survey conducted by EPA and the states. 
The most recent EPA-state estimate, completed in 2008, indicated that nearly $203 billion is 
needed to build and upgrade needed municipal wastewater treatment plants in the United States 
and for other types of water quality improvement projects that are eligible for funding under the 
act. In 2002, EPA released a new report called the Gap Analysis which estimated that, over the 
next two decades, the United States needs to spend nearly $390 billion to replace existing 
wastewater infrastructure systems and to build new ones. Estimates of future funding needs and 
questions about federal support continue to be prominent. 
Under the Title II construction grants program established in 1972, federal grants were made for 
several types of projects (such as secondary or more stringent treatment and associated sewers) 
based on a priority list established by the states. Grants were generally available for as much as 
55% of total project costs. For projects using innovative or alternative technology (such as reuse 
or recycling of water), as much as 75% federal funding was allowed. Recipients were responsible 
for non-federal costs but were not required to repay federal grants. 
Congressional Research Service

Policymakers have debated the tension between assisting municipal funding needs, which remain 
large, and the impact of grant programs such as the Clean Water Act’s on federal spending and 
budget deficits. In the 1987 amendments to the act, Congress attempted to deal with that apparent 
conflict by extending federal aid for wastewater treatment construction through FY1994, yet 
providing a transition towards full state and local government responsibility for financing after 
that date. Grants under the traditional Title II program were authorized through FY1990. Under 
Title VI of the act, grants to capitalize State Water Pollution Control Revolving Funds, or loan 
programs, were authorized beginning in FY1989 to replace the Title II grants. States contribute 
matching funds, and under the revolving loan fund concept, monies used for wastewater 
treatment construction will be repaid to a state, to be available for future construction in other 
communities. All states now have functioning loan programs, but the shift from federal grants to 
loans, since FY1991, has been easier for some than others. The new financing requirements have 
been a problem for cities (especially small towns) that have difficulty repaying project loans. 
Statutory authorization for grants to capitalize state loan programs expired in 1994; however, 
Congress has continued to provide annual appropriations. An issue affecting some cities is 
overflow discharges of inadequately treated wastes from municipal sewers and how cities will 
pay for costly remediation projects. In 2000, Congress amended the act to authorize a two-year 
$1.5 billion grant program to help cities reduce these wet weather flows. Authorization for that 
wet weather grant program expired at the end of FY2003 and has not been renewed. 
Permits, Regulations, and Enforcement 
To achieve its objectives, the act embodies the concept that all discharges into the nation’s waters 
are unlawful, unless specifically authorized by a permit. Thus, more than 65,000 industrial and 
municipal dischargers must obtain permits from EPA (or qualified states) under the act’s National 
Pollutant Discharge Elimination System (NPDES) program (authorized in Section 402 of the act). 
NPDES permits also are required for more than 150,000 industrial and municipal sources of 
stormwater discharges. An NPDES permit requires the discharger (source) to attain technology-
based effluent limits (BPT or BAT for industry, secondary treatment for municipalities, or more 
stringent for water quality protection). Permits specify the control technology applicable to each 
pollutant, the effluent limitations a discharger must meet, and the deadline for compliance. 
Sources are required to maintain records and to carry out effluent monitoring activities. Permits 
are issued for five-year periods and must be renewed thereafter to allow continued discharge. 
The NPDES permit incorporates numerical effluent limitations issued by EPA. The initial BPT 
limitations focused on regulating discharges of conventional pollutants, such as bacteria and 
oxygen-consuming materials. The more stringent BAT limitations emphasize controlling toxic 
pollutants—heavy metals, pesticides, and other organic chemicals. In addition to these limitations 
applicable to categories of industry, EPA has issued water quality criteria for more than 115 
pollutants, including 65 named classes or categories of toxic chemicals, or “priority pollutants.” 
These criteria recommend ambient, or overall, concentration levels for the pollutants and provide 
guidance to states for establishing water quality standards that will achieve the goals of the act. 
A separate type of permit is required to dispose of dredge or fill material in the nation’s waters, 
including wetlands. Authorized by Section 404 of the act, this permit program is administered by 
the U.S. Army Corps of Engineers, subject to and using EPA’s environmental guidance. Some 
types of activities are exempt from these permit requirements, including certain farming, 
ranching, and forestry practices which do not alter the use or character of the land; some 
construction and maintenance; and activities already regulated by states under other provisions of 
Congressional Research Service 
29 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
the act. EPA may delegate certain Section 404 permitting responsibility to qualified states and has 
done so twice (Michigan and New Jersey). For some time, the act’s wetlands permit program has 
been one of the most controversial parts of the law. Some who wish to develop wetlands maintain 
that federal regulation intrudes on and impedes private land-use decisions, while 
environmentalists seek more protection for remaining wetlands and limits on activities that take 
place in wetlands. 
Nonpoint sources of pollution, which EPA and states believe are responsible for the majority of 
water quality impairments in the nation, are not subject to CWA permits or other regulatory 
requirements under federal law. They are covered by state programs for the management of 
runoff, under Section 319 of the act. 
Other EPA regulations under the CWA include guidelines on using and disposing of sewage 
sludge and guidelines for discharging pollutants from land-based sources into the ocean. (A 
related statute, the Ocean Dumping Act, regulates the intentional disposal of wastes into ocean 
waters.) EPA also provides guidance on technologies that will achieve BPT, BAT, and other 
effluent limitations. 
The NPDES permit, containing effluent limitations on what may be discharged by a source, is the 
act’s principal enforcement tool. EPA may issue a compliance order or bring a civil suit in U.S. 
district court against persons who violate the terms of a permit. The penalty for such a violation 
can be as much as $25,000 per day. Stiffer penalties are authorized for criminal violations of the 
act—for negligent or knowing violations—of as much as $50,000 per day, three years’ 
imprisonment, or both. A fine of as much as $250,000, 15 years in prison, or both, is authorized 
for “knowing endangerment”—violations that knowingly place another person in imminent 
danger of death or serious bodily injury. Finally, EPA is authorized to assess civil penalties 
administratively for certain well-documented violations of the law. These civil and criminal 
enforcement provisions are contained in Section 309 of the act. EPA, working with the Army 
Corps of Engineers, also has responsibility for enforcing against entities who engage in activities 
that destroy or alter wetlands. 
While the CWA addresses federal enforcement, the majority of actions taken to enforce the law 
are undertaken by states, both because states issue the majority of permits to dischargers and 
because the federal government lacks the resources for day-to-day monitoring and enforcement. 
Like most other federal environmental laws, CWA enforcement is shared by EPA and states, with 
states having primary responsibility. However, EPA has oversight of state enforcement and retains 
the right to bring a direct action where it believes that a state has failed to take timely and 
appropriate action or where a state or local agency requests EPA involvement. Finally, the federal 
government acts to enforce against criminal violations of the federal law. 
In addition, individuals may bring a citizen suit in U.S. district court against persons who violate 
a prescribed effluent standard or limitation. Individuals also may bring citizen suits against the 
Administrator of EPA or equivalent state official (where program responsibility has been 
delegated to the state) for failure to carry out a nondiscretionary duty under the act.

Ocean Dumping Act15 
The Ocean Dumping Act has two basic aims: to regulate intentional ocean disposal of materials, 
and to authorize related research. Title I of the Marine Protection, Research, and Sanctuaries Act 
of 1972 (MPRSA, P.L. 92-532), which is often referred to just as the Ocean Dumping Act, 
contains permit and enforcement provisions for ocean dumping. Research provisions are 
contained in Title II, concerning general and ocean disposal research. Title IV established a 
regional marine research program, and Title V addresses coastal water quality monitoring. Title 
III of the MPRSA, not addressed here, authorizes the establishment of marine sanctuaries. Table 
6 shows the original enactment and subsequent amendments.

Background 
The nature of marine pollution requires that it be regulated internationally, since once a pollutant 
enters marine waters, it knows no boundary. Thus, a series of regional treaties and conventions 
pertaining to local marine pollution problems and more comprehensive international conventions 
providing uniform standards to control worldwide marine pollution has evolved over the last 35 
years.

At the same time that key international protocols were being adopted and ratified by large number 
of countries worldwide (early 1970s), the United States enacted the MPRSA to regulate disposal 
of wastes in marine waters that are within U.S. jurisdiction. It utilizes a comprehensive and 
uniform waste management system to regulate disposal or dumping of all materials into ocean 
waters. Prior to 1972, U.S. marine waters had been used extensively as a convenient alternative to 
land-based sites for the disposal of various wastes such as sewage sludge, industrial wastes, and 
pipeline discharges and runoff. 
The basic provisions of the act have remained virtually unchanged since 1972, but many new 
authorities have been added. These newer parts include (1) research responsibilities for EPA; (2) 
specific direction that EPA phase out the disposal of “harmful” sewage sludges and industrial 
wastes; (3) a ban on the ocean disposal of sewage sludge and industrial wastes by December 31, 
1991; (4) inclusion of Long Island Sound within the purview of the act; and (5) inclusion of 
medical waste provisions. Authorizations for appropriations to support provisions of the law 
expired at the end of FY1997 (September 30, 1997). Authorities did not lapse, however, and 
Congress has continued to appropriate funds to carry out the act. 
Four federal agencies have responsibilities under the Ocean Dumping Act: EPA, the U.S. Army 
Corps of Engineers, the National Oceanic and Atmospheric Administration (NOAA), and the 
Coast Guard. EPA has primary authority for regulating ocean disposal of all substances except 
dredged spoils, which are under the authority of the Corps of Engineers. NOAA is responsible for 
long-range research on the effects of human-induced changes to the marine environment, while 
EPA is authorized to carry out research and demonstration activities related to phasing out sewage 
sludge and industrial waste dumping. The Coast Guard is charged with maintaining surveillance 
of ocean dumping. 
Regulating Ocean Dumping 
Title I of the MPRSA prohibits all ocean dumping, except that allowed by permits, in any ocean 
waters under U.S. jurisdiction, by any U.S. vessel, or by any vessel sailing from a U.S. port. The 
act bans any dumping of radiological, chemical, and biological warfare agents and any high-level 
radioactive waste, and medical wastes. Permits for dumping of other materials, except dredge 
spoils, can be issued by the EPA after notice and opportunity for public hearings where the 
Administrator determines that such dumping will not unreasonably degrade or endanger human 
health, welfare, the marine environment, ecological systems, or economic potentialities. The law 
regulates ocean dumping within the area extending 12 nautical miles seaward from the U.S. 
baseline and regulates transport of material by U.S.-flagged vessels for dumping into ocean 
waters. EPA designates sites for ocean dumping and specifies in each permit where the material is 
to be disposed. EPA prepares an annual report on ocean dumping permits for material other than 
dredged material (although the most recent report was issued in 2006).16 
In 1977, Congress amended the act to require that dumping of municipal sewage sludge or 
industrial wastes which unreasonably degrade the environment cease by December 1981. In 1986 
amendments, Congress directed that ocean disposal of all wastes cease at the traditional 12-mile 
site off the New York/New Jersey coast (that is, barred issuance of permits at the 12-mile site) 
and be moved to a new site 106 miles offshore. In 1988, Congress enacted several laws amending

the Ocean Dumping Act, with particular emphasis on phasing out sewage sludge and industrial 
waste disposal in the ocean, which continued despite earlier legislative efforts. 
In 1992, Congress amended the act to permit states to adopt ocean dumping standards more 
stringent than federal standards and to require that permits conform with long-term management 
plans for designated marine dumpsites, to ensure that permitted activities are consistent with 
expected uses of the site. 
Virtually all ocean dumping that occurs today is dredged material—sediments removed from the 
bottom of water bodies in order to maintain navigation channels and berthing areas. The Corps of 
Engineers issues permits for ocean dumping of dredged material, the bulk of which results from 
maintenance dredging by the Corps itself or its contractors. According to data compiled by the 
Corps, each year an average of 70 million cubic yards of dredged sediment material is disposed of 
in the ocean at designated sites. Before sediments can be permitted to be dumped in the ocean, 
they are evaluated to ensure that the dumping will not cause significant harmful effects to human 
health or the marine environment. EPA is responsible for developing criteria to ensure that the 
ocean disposal of dredge spoils does not cause environmental harm. Permits for ocean disposal of 
dredged material are to be based on the same criteria utilized by EPA under other provisions of 
the act, and to the extent possible, EPA-recommended dumping sites are used. Where the only 
feasible disposition of dredged material would violate the dumping criteria, the Corps can request 
an EPA waiver. Amendments enacted in 1992 expanded EPA’s role in permitting of dredged 
material by authorizing EPA to impose permit conditions or even deny a permit, if necessary to 
prevent environmental problems. 
Permits issued under the Ocean Dumping Act specify the type of material to be disposed, the 
amount to be transported for dumping, the location of the dumpsite, the length of time the permit 
is valid, and special provisions for surveillance. The EPA Administrator can require a permit 
applicant to provide information necessary for the review and evaluation of the application. 
Enforcement 
The act authorizes EPA to assess civil penalties of not more than $50,000 for each violation of a 
permit or permit requirement, taking into account such factors as gravity of the violation, prior 
violations, and demonstrations of good faith; however, no penalty can be assessed until after 
notice and opportunity for a hearing. Criminal penalties (including seizure and forfeiture of 
vessels) for knowing violations of the act also are authorized. In addition, the act authorizes 
penalties for ocean dumping of medical wastes (civil penalties up to $125,000 for each violation 
and criminal penalties up to $250,000, five years in prison, or both). The Coast Guard is directed 
to conduct surveillance and other appropriate enforcement activities to prevent unlawful 
transportation of material for dumping, or unlawful dumping. Like many other federal 
environmental laws, the Ocean Dumping Act allows individuals to bring a citizen suit in U.S. 
district court against any person, including the United States, for violation of a permit or other 
prohibition, limitation, or criterion issued under Title I of the act. 
In conjunction with the Ocean Dumping Act, the Clean Water Act (CWA) regulates all discharges 
into navigable waters including the territorial seas. Although these two laws overlap in their 
coverage of dumping from vessels within the territorial seas, any question of conflict is 
essentially moot because EPA has promulgated a uniform set of standards (40 C.F.R. Parts 220-
229). The Ocean Dumping Act preempts the CWA in coastal waters or open oceans, and the CWA

controls in estuaries. States are permitted to regulate ocean dumping in waters within their 
jurisdiction under certain circumstances. 
The act also requires the EPA Administrator, to the extent possible, to apply the standards and 
criteria binding upon the United States that are stated in the 1972 Convention on the Prevention 
of Marine Pollution by Dumping of Wastes and Other Matters (known as the London Dumping 
Convention). This Convention, signed by more than 85 countries, includes Annexes that prohibit 
the dumping of mercury, cadmium and other substances such as DDT and PCBs, solid wastes and 
persistent plastics, oil, high-level radioactive wastes, and chemical and biological warfare agents; 
and requires special permits for other heavy metals, cyanides and fluorides, and medium- and 
low-level radioactive wastes. 
Research and Coastal Water Quality Monitoring 
Title II of the MPRSA authorizes two types of research: general research on ocean resources, 
under the jurisdiction of the National Oceanic and Atmospheric Administration (NOAA); and 
EPA research related to phasing out ocean disposal activities. 
NOAA is directed to carry out a comprehensive, long-term research program on the effects not 
only of ocean dumping, but also of pollution, overfishing, and other human-induced changes on 
the marine ecosystem. Additionally, NOAA assesses damages from spills of petroleum and 
petroleum products. 
EPA’s research role includes “research, investigations, experiments, training, demonstrations, 
surveys, and studies” to minimize or end the dumping of sewage sludge and industrial wastes, 
along with research on alternatives to ocean disposal. Amendments in 1980 required EPA to study 
technological options for removing heavy metals and certain organic materials from New York 
City’s sewage sludge. 
Title IV of the MPRSA established nine regional marine research boards for the purpose of 
developing comprehensive marine research plans, considering water quality and ecosystem 
conditions and research and monitoring priorities and objectives in each region. The plans, after 
approval by NOAA and EPA, are to guide NOAA in awarding research grant funds under this title 
of the act. 
Title V of the MPRSA established a national coastal water quality monitoring program. It directs 
EPA and NOAA jointly to implement a long-term program to collect and analyze scientific data 
on the environmental quality of coastal ecosystems, including ambient water quality, health and 
quality of living resources, sources of environmental degradation, and data on trends. Results of 
these activities (including intensive monitoring of key coastal waters) are intended to provide 
information necessary to design and implement effective programs under the Clean Water Act and 
Coastal Zone Management Act.

Safe Drinking Water Act17 
The Safe Drinking Water Act (SDWA), Title XIV of the Public Health Service Act, is the key 
federal law for protecting public water supplies from harmful contaminants. First enacted in 1974 
and substantively amended in 1986 and 1996, the act is administered through programs that 
establish standards and treatment requirements for public water supplies, control underground 
injection of wastes, finance infrastructure projects, and protect sources of drinking water. The 
1974 law established the current federal-state arrangement in which states may be delegated 
primary implementation and enforcement authority for the drinking water program. The state-
administered Public Water Supply Supervision (PWSS) Program remains the basic program for 
regulating the nation’s public water systems, and 49 states have assumed this authority. SDWA 
appropriations were authorized through FY2003. 
Background 
As indicated in Table 8, the Safe Drinking Water Act has been amended several times since 
enactment of the Safe Drinking Water Act of 1974 (P.L. 93-523). Congress enacted P.L. 93-523 
after nationwide studies of community water systems revealed widespread water quality problems 
and health risks resulting from poor operating procedures, inadequate facilities, and poor 
management of public water supplies in communities of all sizes. The 1974 law gave EPA 
substantial discretionary authority to regulate drinking water contaminants and gave states the 
lead role in implementation and enforcement.

The first major amendments (P.L. 99-339), enacted in 1986, were largely intended to increase the 
pace at which EPA regulated contaminants. From 1974 until 1986, EPA had regulated just one 
additional contaminant beyond the 22 standards previously developed by the Public Health 
Service. The 1986 amendments required EPA to (1) issue regulations for 83 specified 
contaminants by June 1989 and for 25 more contaminants every three years thereafter, (2) 
promulgate requirements for disinfection and filtration of public water supplies, (3) ban the use of 
lead pipes and lead solder in new drinking water systems, (4) establish an elective wellhead 
protection program around public wells, (5) establish a demonstration grant program for state and 
local authorities having designated sole-source aquifers to develop groundwater protection 
programs, and (6) issue rules for monitoring injection wells that inject wastes below a drinking 
water source. The amendments also increased EPA’s enforcement authority. 
The Lead Contamination Control Act of 1988 (P.L. 100-572) added a new Part F to the SDWA. 
These provisions were intended to reduce exposure to lead in drinking water by requiring the 
recall of lead-lined water coolers, and requiring EPA to issue a guidance document and testing 
protocol for states to help schools and day care centers identify and correct lead contamination in 
school drinking water. 
After the regulatory schedule mandated in the 1986 amendments proved to be unworkable for 
EPA, states and public water systems, the 104th Congress made sweeping changes to the act with 
the SDWA Amendments of 1996 (P.L. 104-182). As over-arching themes, these amendments 
aimed to target resources to address the greatest health risks, add some regulatory flexibility, 
provide funding for federal drinking water mandates, and improve water systems’ compliance 
capacity. The amendments revoked the requirement that EPA regulate 25 new contaminants every 
three years, and provided a risk-based approach for selecting contaminants for regulation. Among 
other changes, Congress added some flexibility to the standard-setting process, required EPA to 
conduct health risk reduction and cost analyses for most new standards, authorized a state 
revolving loan fund (SRF) program to help public water systems finance projects needed to meet 
SDWA requirements, added programs to improve small system compliance, expanded consumer 
information requirements, increased the act’s focus on pollution prevention through a voluntary 
source water protection program, and streamlined the act’s enforcement provisions. P.L. 104-182 
extended authorizations for appropriations under the act through FY2003. 
Congressional Research Service 
40 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
In June 2002, drinking water security provisions were added to the SDWA through the Public 
Heath Security and Bioterrorism Preparedness and Response Act of 2002 (P.L. 107-188). Key 
provisions of the act include requirements for community water systems serving more than 3,300 
individuals to conduct vulnerability assessments and prepare emergency preparedness and 
response plans and requirements for EPA to conduct research on preventing and responding to 
terrorist or other attacks. 
National Drinking Water Regulations 
A key component of the SDWA is the requirement that EPA promulgate national primary drinking 
water regulations for contaminants that may pose health risks and that are likely to be present in 
public water supplies. Section 1412 instructs EPA on how to select contaminants for regulation 
and specifies how EPA must establish regulations once a contaminant has been selected. The 
regulations apply to the roughly 168,000 privately and publicly owned water systems that provide 
piped water for human consumption to at least 15 service connections or that regularly serve at 
least 25 people. EPA has issued regulations for roughly 90 contaminants. 
Contaminant Selection and Regulatory Schedules 
Section 1412, as amended in 1996, directs EPA to select contaminants for regulatory 
consideration based on occurrence, health effects, and meaningful opportunity for health risk 
reduction. Starting in 1998, and every five years thereafter, EPA must publish a list of 
contaminants that may warrant regulation. Starting in 2001, and every five years thereafter, EPA 
must determine whether or not to regulate at least five of the listed contaminants. The act requires 
EPA to evaluate contaminants that present the greatest health concern and to regulate 
contaminants that occur at concentration levels and frequencies of public health concern. The 
amendments also included schedules for EPA to complete regulations for specific contaminants 
(i.e., radon, arsenic, disinfectants and disinfection byproducts, and Cryptosproridium). 
Standard Setting 
For each contaminant that EPA determines requires regulation, EPA must set a non-enforceable 
maximum contaminant level goal (MCLG) at a level at which no known or anticipated adverse 
health effects occur and which allows an adequate margin of safety. EPA must then set an 
enforceable standard, a maximum contaminant level (MCL), as close to the MCLG as is 
“feasible” using best technology, treatment techniques, or other means available (taking costs into 
consideration). EPA generally sets standards based on technologies that are affordable for large 
communities; however, under P.L. 104-182, EPA is now required, when issuing a regulation for a 
contaminant, to list any technologies or other means that comply with the MCL and that are 
affordable for three categories of small public water systems (serving populations of 10,000 or 
fewer). If EPA does not identify technologies that are affordable for small systems, then EPA must 
identify small system “variance” technologies or other means that may not achieve the MCL but 
are protective of public health. 
Another provision added in 1996 requires EPA, when proposing a regulation, to publish a 
determination as to whether or not the benefits of the standard justify the costs. If EPA determines 
that the benefits do not justify the costs, EPA may, with certain exceptions, promulgate a standard 
that maximizes health risk reduction benefits at a cost that is justified by the benefits. 
Congressional Research Service 
41 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
New SDWA regulations generally become effective three years after promulgation. Up to two 
additional years may be allowed if EPA (or a state in the case of an individual system) determines 
the time is needed for capital improvements. Section 1448 outlines procedures for judicial review 
of EPA actions involving the establishment of SDWA regulations and other final EPA actions. 
Risk Assessment 
The 1996 amendments also added risk assessment and risk communication provisions to SDWA. 
When developing regulations, EPA is required to (1) use the best available, peer-reviewed science 
and supporting studies and data; and (2) make publicly available a risk assessment document that 
discusses estimated risks, uncertainties, and studies used in the assessment. When proposing 
drinking water regulations, EPA must publish a health risk reduction and cost analysis (HRRCA). 
EPA may promulgate an interim standard without first preparing this benefit-cost analysis or 
making a determination as to whether the benefits of a regulation would justify the costs if EPA 
determines that a contaminant presents an urgent threat to public health. 
Variances and Exemptions 
In anticipation that some systems, particularly smaller ones, could have difficulty complying with 
every regulation, Congress included in the SDWA provisions for variances and exemptions. 
Section 1415 authorizes a state to grant a public water system a variance from a standard if raw 
water quality prevents the standard from being met despite application of best technology, and the 
variance does not result in an unreasonable risk to health. A 1996 provision (Subsection 1415(e)) 
authorizes variances specifically for small systems based on application of best affordable 
technology. 
When developing a regulation, if EPA cannot identify a technology that meets the standard and is 
affordable for small systems, EPA must identify variance technologies that are affordable but do 
not necessarily meet the standard. In cases where EPA has identified variance technologies, states 
may grant small system variances to systems serving 3,300 or fewer persons if the system cannot 
afford to comply with a standard (through treatment, an alternative water source, or restructuring) 
and the variance ensures adequate protection of public health. States also may grant these 
variances to systems serving between 3,301 and 10,000 persons with EPA approval. To receive a 
small system variance, the system must install a variance technology. 
Section 1416 authorizes states to grant public water systems temporary exemptions from 
standards or treatment techniques if a system cannot comply for other compelling reasons 
(including costs). An exemption is intended to give a water system more time to comply with a 
regulation and can be issued only if it will not result in an unreasonable health risk. A qualified 
system may receive an exemption for up to three years beyond the compliance deadline. Systems 
serving 3,300 or fewer persons may receive a maximum of three additional two-year extensions, 
for a total exemption duration of nine years. 
State Primacy 
Section 1413 authorizes states to assume primary oversight and enforcement responsibility 
(primacy) for public water systems. To assume primacy, states must adopt regulations at least as 
stringent as national requirements, develop adequate procedures for enforcement, adopt authority 
for administrative penalties, maintain records, and develop a plan for providing emergency water

supplies. Currently, 55 of 57 states and territories have primacy authority. The act authorizes $100 
million annually for EPA to make grants to states to administer the Public Water System 
Supervision Program. States may also use part of their SRF grant for this purpose. 
Enforcement, Consumer Information, and Citizen Suits 
The Safe Drinking Water Act requires public water systems to monitor their water supplies to 
ensure compliance with drinking water standards and to report monitoring results to the states. 
States review monitoring data submitted by public water systems, or conduct their own 
monitoring, to determine system compliance with drinking water regulations. EPA monitors 
public water system compliance primarily by reviewing the violation data submitted by the states. 
Section 1414 requires that, whenever EPA finds that a public water system in a state with primary 
enforcement authority does not comply with regulations, the agency must notify the state and the 
system and provide assistance to bring the system into compliance. If the state fails to commence 
enforcement action within 30 days after the notification, EPA is authorized to issue an 
administrative order or commence a civil action. In a non-primacy state, EPA must notify an 
elected local official (if any has jurisdiction over the water system) before commencing an 
enforcement action against the system. 
The 1996 amendments strengthened enforcement authorities, streamlined the process for issuing 
federal administrative orders, increased administrative penalty amounts, made more sections of 
the act clearly subject to EPA enforcement, and required states (as a condition of primacy) to have 
administrative penalty authority. The amendments also provided that no enforcement action may 
be taken against a public water system that has a plan to consolidate with another system. 
Consumer Information and Reports 
Enforcement provisions also require public water systems to notify customers of violations of 
drinking water standards or other requirements, such as monitoring and reporting. Systems must 
notify customers within 24 hours of any violations that have the potential to cause serious health 
effects as a result of short-term exposure (e.g., violations of microbial standards). The 
amendments also require community water systems to mail to all customers an annual “ consumer 
confidence report” on contaminants detected in their drinking water. States must prepare annual 
reports on the compliance of public water systems and make summaries available to EPA and the 
public, and EPA must prepare annual national compliance reports. 
Citizen Suits 
Section 1449 provides for citizens’ civil actions. Citizen suits may be brought against any person 
or agency allegedly in violation of provisions of the act, or against the Administrator for alleged 
failure to perform any action or duty that is not discretionary. 
Compliance Improvement Programs 
The 1996 amendments added two state-administered programs aimed at improving public water 
system compliance with drinking water regulations: the operator certification program and the 
capacity development program. Section 1419 required states to adopt programs for training and 
Congressional Research Service 
43 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
certifying operators of community and non-transient non-community systems (e.g., schools and 
workplaces that have their own wells). In 1999, EPA issued guidelines specifying minimum 
certification standards. EPA is required to withhold 20% of a state’s revolving fund (SRF) annual 
grant unless the state has adopted and is implementing an operator certification program. Section 
1420 required states to establish capacity development programs, also based on EPA guidance. 
These programs must include (1) legal authority to ensure that new systems have the technical, 
financial, and managerial capacity to meet SDWA requirements; and (2) a strategy to assist 
existing systems that are experiencing difficulties to come into compliance. EPA is required to 
withhold a portion of SRF grants from states that do not have capacity development strategies. 
Ground Water Protection Programs 
Most small water systems rely on ground water as a source of drinking water, and Part C of the 
act focuses on ground water protection. Section 1421 authorized the establishment of state 
underground injection control (UIC) programs to protect underground sources of drinking water. 
In 1977, EPA issued mandated regulations containing minimum requirements for the underground 
injection of wastes into five classes of disposal wells and requiring states to prohibit any 
underground injection not authorized by state permit. The law specified that the regulations could 
not interfere with the underground injection of brine from oil and gas production or recovery of 
oil unless underground sources of drinking water would be affected. Section 1422 authorized 
affected states to submit plans to EPA for implementing UIC programs and, if approved, to 
assume primary enforcement responsibility. EPA is required to implement the program if a state’s 
plan has not been approved or the state has chosen not to assume program responsibility (Section 
1423). For oil and gas injection operations only, states with UIC programs are delegated primary 
enforcement authority without meeting EPA regulations (Section 1425). 
Section 1424(e) authorizes EPA to make determinations, on EPA’s initiative or upon petition, that 
an aquifer is the sole or principal drinking water source for an area. In areas that overlie a 
designated sole-source aquifer, no federal funding may be committed for projects that EPA 
determines may contaminate such an aquifer. Any person may petition for sole source aquifer 
designation. 
The act contains three additional state programs aimed specifically at protecting ground water. 
Added in 1986, Section 1427 established procedures for demonstration programs to develop, 
implement, and assess critical aquifer protection areas already designated by the Administrator as 
sole source aquifers. Section 1428, also added in 1986, established an elective state program for 
protecting wellhead areas around public water system wells. If a state established a wellhead 
protection program by 1989, and EPA approved the state’s program, then EPA may award grants 
covering between 50% and 90% of the costs of implementing the program. Section 1429, added 
in 1996, authorizes EPA to make 50% grants to states to develop programs to ensure coordinated 
and comprehensive protection of ground water within the states. Appropriations for these three 
programs and for UIC state program grants were authorized through FY2003. 
Source Water Assessment and Protection Programs 
In 1996, Congress broadened the act’s pollution prevention focus to embrace surface water, in 
addition to ground water, protection. Section 1453 required EPA to publish guidance for states to 
implement source water assessment programs that delineate boundaries of areas from which 
systems receive their water, and identify the origins of contaminants in delineated areas to 
Congressional Research Service 
44 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
determine systems’ susceptibility to contamination. States with approved assessment programs 
may adopt alternative monitoring requirements to provide systems with monitoring relief 
provided under Section 1418. 
Section 1454 authorized a source water petition program based on voluntary partnerships between 
state and local governments. States may establish a program under which a community water 
system or local government may submit a petition to the state requesting assistance in developing 
a voluntary source water quality protection partnership to (1) reduce the presence of contaminants 
in drinking water; (2) receive financial or technical assistance; and (3) develop a long-term source 
water protection strategy. This section authorized, through FY2003, $5 million each year for 
grants to states to support petition programs. States also may use 10% of their annual SRF grant 
to support various source water protection activities including the petition program. 
State Revolving Funds 
In 1996, Congress authorized a drinking water state revolving loan fund (DWSRF) program to 
help systems finance improvements needed to comply with SDWA regulations (Section 1452). 
EPA is authorized to make grants to states to capitalize DWSRFs, which states then may use to 
make loans to public water systems. States must match 20% of the federal grant, and grants are 
allotted among the states based on the results of the latest quadrennial needs survey. Each state 
and the District of Columbia must receive at least 1% of the appropriated funds. A state may 
transfer up to 33% of the grant to the Clean Water Act (CWA) SRF, or an equivalent amount from 
the CWA SRF to the DWSRF through FY2002. This authority has been extended in subsequent 
appropriations acts. 
DWSRFs may be used to provide loans for expenditures EPA has determined will facilitate 
compliance or significantly further the act’s health protection objectives. States must make 
available 15% of their annual allotment for loan assistance to systems that serve 10,000 or fewer 
persons, to the extent that funds can be obligated for eligible projects. States may use up to 30% 
of their DWSRF grant to provide loan subsidies (including forgiveness of principal) to help 
economically disadvantaged communities. Also, states may use a portion of funds for technical 
assistance, source water protection and capacity development programs, and for operator 
certification. The law authorized appropriations of $599 million for FY1994 and $1 billion per 
year for FY1995 through FY2003 for the DWSRF program. 
Drinking Water Security 
The 107th Congress passed the Public Health Security and Bioterrorism Preparedness and 
Response Act of 2002 (P.L. 107-188). Title IV of the Bioterrorism Act amended the SDWA to 
address threats to drinking water security. Key provisions are summarized below. 
Vulnerability Assessments 
Section 1433 was added to SDWA, requiring each community water system serving more than 
3,300 individuals to conduct an assessment of the system’s vulnerability to terrorist attacks or 
other intentional acts to disrupt the provision of a safe and reliable drinking water supply. This 
provision established deadlines, based on system size, for community water systems to certify to 
EPA that they had conducted a vulnerability assessment and to submit to EPA a copy of the 
Congressional Research Service 
45 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
assessment. The law required all these systems to complete vulnerability assessments by June 30, 
2004, or earlier. Section 1433 exempts the contents of the vulnerability assessments from 
disclosure under the Freedom of Information Act (except for information contained in the 
certification identifying the system and the date of the certification), and provides for civil and 
criminal penalties for inappropriate disclosure of information by government officials. 
In addition, Section 1433 required each community water system serving more than 3,300 
individuals to prepare or revise an emergency response plan incorporating the results of the 
vulnerability assessment. EPA was required to provide guidance to smaller systems on how to 
conduct vulnerability assessments, prepare emergency response plans, and address threats. 
The act authorized $160 million for FY2002, and such sums as may be necessary for FY2003 
through FY2005, to provide financial assistance to community water systems to conduct 
vulnerability assessments, to prepare response plans, and to address basic security enhancements 
and significant threats. 
The Bioterrorism Act also added new SDWA Sections 1434 and 1435 directing the EPA 
Administrator to review methods by which terrorists or others could disrupt the provision of safe 
water supplies. EPA was required to review methods for preventing, detecting, and responding to 
such disruptions, and methods for providing alternative drinking water supplies if a water system 
was destroyed or impaired. The act authorized $15 million for FY2002, and such sums as may be 
necessary for FY2003 through FY2005 to carry out these sections. 
Emergency Powers 
Under Section 1431, the Administrator has emergency powers to issue orders and commence civil 
action if (1) a contaminant likely to enter a public water supply system poses a substantial threat 
to public health, and (2) state or local officials have not taken adequate action. The Bioterrorism 
Act amended this section to specify that EPA’s emergency powers include the authority to act 
when there is a threatened or potential terrorist attack or other intentional act to disrupt the 
provision of safe drinking water or to impact the safety of a community’s water supply. 
Tampering with Public Water Systems 
Section 1432 provides for civil and criminal penalties against any person who tampers, attempts 
to tamper, or makes a threat to tamper with a public water system. Amendments made by the 
Bioterrorism Act increased criminal and civil penalties for tampering, attempting to tamper, or 
making threats to tamper with public water supplies. The maximum prison sentence for tampering 
was increased from 5 to 20 years. The maximum prison sentence for attempting to tamper, or 
making threats to tamper, was increased from 3 to 10 years. The maximum fine that may be 
imposed for tampering was increased from $50,000 to $1 million. The maximum fine for 
attempting to tamper, or threatening to tamper, was increased from $20,000 to $100,000. 
Emergency Assistance 
SDWA Subsection 1442(b) authorizes EPA to provide technical assistance and to make grants to 
states and public water systems to assist in responding to and alleviating emergency situations. 
The Bioterrorism Act amended Subsection 1442(d) to authorize appropriations for such 
Congressional Research Service 
46 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
emergency assistance of not more than $35 million for FY2002, and such sums as may be 
necessary for each fiscal year thereafter. 
Other Selected Provisions 
Section 1417 prohibits the use of pipe, solder, or flux that is not “lead free” (as defined by the 
SDWA) in the installation or repair of public water systems or plumbing in residential or other 
facilities providing drinking water. It prohibits the sale of potable water pipes, pipe fittings, 
plumbing fittings and fixtures that are not lead free, and the sale of solder or flux that is not lead 
free (unless it is properly labeled). This section’s prohibitions do not apply to pipes, fittings or 
fixtures used exclusively for nonpotable services, such as manufacturing, industrial processing, 
outdoor watering, and irrigation.18 
Section 1442 authorizes EPA to conduct research on the causes, treatment, control, and 
prevention of diseases resulting from contaminants in water. Section 1442(b) authorizes EPA to 
make grants and provide technical assistance to states or public water systems to assist them in 
responding to emergency situations; $35 million are authorized to be appropriated each year for 
this purpose. Section 1442(e) authorized $15 million for each year, through FY2003, for EPA to 
provide technical assistance to small public water systems and Indian Tribes to help them comply 
with SDWA regulations. Section 1458 directed EPA to conduct studies regarding subpopulations 
at greater risk, biological mechanisms, and waterborne disease occurrences. 
Section 1447 provides that any federal agency having jurisdiction over federally owned and 
maintained public water systems must comply with all federal, state and local drinking water 
requirements as well as any underground injection control programs. The President may exempt a 
facility from compliance with a requirement if he determines it to be in the paramount interest of 
the country to do so. Exemptions last one year, but additional exemptions may be granted. 
Under Section 1457, EPA may use the estrogenic substances screening program created in the 
Food Quality Protection Act of 1996 (P.L. 104-170) to provide for testing of substances that may 
be found in drinking water, if the Administrator determines that a substantial population may be 
exposed to such substances. 
                                                                  
18 For purposes of Section 1417, as amended by the Reduction of Lead in Drinking Water Act, P.L. 111-380, the term 
“lead free” means solders and flux containing not more than 0.2% lead; and water pipes, pipe fittings, plumbing fittings 
and fixtures containing not more than 0.25% lead.

Solid Waste Disposal Act/Resource Conservation 
and Recovery Act19 
The Resource Conservation and Recovery Act of 1976 (RCRA) established the federal program 
regulating solid and hazardous waste management. RCRA actually amends earlier legislation (the 
Solid Waste Disposal Act of 1965), but the amendments were so comprehensive that the act is 
commonly called RCRA rather than its official title. 
The act defines solid and hazardous waste, authorizes EPA to set standards for facilities that 
generate or manage hazardous waste, establishes a permit program for hazardous waste treatment, 
storage, and disposal facilities, and authorizes EPA to set criteria for disposal facilities that accept 
municipal solid waste. RCRA was last reauthorized by the Hazardous and Solid Waste 
Amendments of 1984. The amendments set deadlines for permit issuance, prohibited the land 
disposal of many types of hazardous waste without prior treatment, established criteria applicable 
to municipal solid waste landfills, and established a new program regulating underground storage 
tanks. The authorization for appropriations under this act expired September 30, 1988, but 
funding for the EPA’s programs in this area has continued; the act’s other authorities do not 
expire.

Background 
Enacted in 1965 under Title II of the Clean Air Act of 1965, the Solid Waste Disposal Act focused 
on research, demonstrations, and training. It provided for sharing with the states the costs of 
making surveys of waste disposal practices and problems, and of developing waste management 
plans. The Resource Recovery Act of 1970 changed the whole tone of the legislation from

efficiency of disposal to concern with the reclamation of energy and materials from solid waste. It 
authorized grants for demonstrating new resource recovery technology, and required annual 
reports from EPA on means of promoting recycling and reducing the generation of waste.  
The federal government embarked on a more active, regulatory role, embodied in the Resource 
Conservation and Recovery Act of 1976. RCRA instituted the first federal permit program for 
hazardous waste management programs and prohibited open dumps. Under the Hazardous and 
Solid Waste Amendments of 1984 (HSWA), the federal government attempted to prevent future 
cleanup problems by prohibiting land disposal of untreated hazardous wastes; setting liner and 
leachate collection requirements for land disposal facilities; setting deadlines for closure of 
facilities not meeting standards; and establishing a corrective action program to investigate and 
clean up releases of hazardous wastes. 
Waste Management Requirements 
How a waste must be managed depends on whether it is a “solid waste” or a “hazardous waste.” 
Hazardous wastes are regulated in accordance with federal standards. The management of non-
hazardous solid waste is left primarily to individual states. RCRA defines solid waste broadly as  
…any garbage, refuse, sludge from a waste treatment plant, water supply treatment plant, or 
air pollution control facility and other discarded material, including solid, liquid, semisolid, 
or contained gaseous material resulting from industrial, commercial, mining, and agricultural 
operations, and from community activities, but does not include solid or dissolved material 
in domestic sewage, or solid or dissolved materials in irrigation return flows or industrial 
discharges which are point sources [regulated under the Clean Water Act]…or special 
nuclear, or byproduct material as defined by the Atomic Energy Act.20  
As ultimately determined by EPA, a solid waste becomes a hazardous waste21 in one of two 
ways—it may be deemed hazardous because it exhibits certain hazardous characteristics 
(ignitability, corrosivity, reactivity, or toxicity), or it may be deemed hazardous if EPA 
specifically lists the waste as such.22 Hence, hazardous wastes are referred to as “characteristic” 
or “listed” wastes.23 
Hazardous Waste Management Requirements 
If a waste is ultimately determined to be hazardous, then it may be subject to the requirements of 
RCRA Subtitle C and the implementing regulations.24 Under Subtitle C, EPA has broad authority 
to regulate hazardous waste from its generation to its ultimate disposal (and beyond, if disposal 
leads to contamination of air, soil, or water). The rules governing every phase of the waste’s 
                                                                  
20 See 42 U.S.C. §6903(27).  
21 Hazardous waste is a subset of solid waste. A waste must first be determined to be a solid waste before it can meet 
the definition of hazardous waste. Solid waste is further defined in the RCRA regulations at 40 C.F.R. Part 261.2. 
Hazardous waste is defined at 40 C.F.R. Part 261.3. 
22 See 42 U.S.C. 6921(a), and implementing regulations at 40 C.F.R Part 261, “Subpart B—Criteria for Identifying the 
Characteristics of Hazardous Waste and for Listing Hazardous Waste.” 
23 Criteria for listing hazardous waste are found at 40 C.F.R. Part 261.11; those identified waste are listed under 40 
C.F.R. Part 261.31-261.33.

management is often referred to as “cradle to grave.” Under Subtitle C’s requirements, EPA was 
directed to 
•  establish standards applicable to hazardous waste generators and transporters;  
•  establish minimum national standards applicable to owners and operators of 
hazardous waste treatment, storage, and disposal facilities (TSDFs);  
•  establish a permit program applicable to TSDFs; and 
•  establish criteria for states to administer and enforce their own hazardous waste 
program. 
With regard to hazardous waste generators, EPA established standards that include regulations 
concerning record keeping and reporting, waste accumulation time limits, and storage 
requirements, among other requirements.25 With regard to hazardous waste transporters, EPA 
established standards that were coordinated by EPA with existing regulations of the Department 
of Transportation.26 
EPA was directed to establish design and operating standards for hazardous waste treatment, 
storage, and disposal facilities (TSDFs), including standards for waste piles, landfills, and surface 
impoundments.27 Under Subtitle C, land disposal of hazardous waste is prohibited unless the 
waste is first treated to meet certain treatment standards or unless the waste is disposed in a unit 
from which there will be no migration of hazardous constituents for as long as the waste remains 
hazardous. Further, TSDFs regulated under Subtitle C are required to clean up any releases of 
hazardous waste or constituents from solid waste management units at the facility, as well as 
beyond the facility boundary, as necessary to protect human health and the environment. RCRA 
Subtitle C also requires TSDFs to demonstrate that they have adequate financial resources (i.e., 
financial assurance) for obligations, such as closure, post-closure care, necessary cleanup, and 
any liability from facility operations. TSDFs are required to operate in accordance with a permit 
that incorporates all of the design and operating standards established by EPA rules. 
EPA has primary responsibility for implementing the hazardous waste program. However, states 
may seek to implement their own hazardous waste management programs (including the TSDF 
permitting program).28 EPA will authorize states to implement a hazardous waste management 
program that is at least as stringent as the federal program. Currently, EPA implements the 
hazardous waste management program in Iowa, Alaska, Indian Country, and the territories, except 
Guam. All other states implement their own programs, while EPA maintains oversight of them.  
As EPA develops new regulations, a state-implemented program must be reviewed to determine 
whether the state has authority to enforce comparable requirements.29 As a result, many states are 
also authorized to implement individual RCRA program elements that EPA promulgated after 
                                                                  
25 Regulations applicable to hazardous waste generators are listed under 40 C.F.R. Part 262. For more information, see 
EPA’s “Hazardous Waste Generators” webpage at Http://www.epa.gov/epawaste/hazard/generation/index.htm.

1984 (e.g., Corrective Action, Landfill Disposal Restrictions, and Recycled Used Oil 
Management Standards).30  
Criminal violations of Subtitle C requirements are punishable by fines of as much as $50,000 for 
each day of violation and/or imprisonment for as long as five years; knowingly endangering 
human life brings fines of as much as $250,000 ($1 million for a company or organization) and as 
long as 15 years imprisonment. 
In cases not involving criminal conduct, the act authorizes civil and administrative penalties of as 
much as $25,000 per day of violation. EPA is authorized both to issue administrative compliance 
orders and to seek injunctive relief through the courts. Similar civil and administrative penalties 
(but not criminal penalties) apply to violations of the underground storage tank requirements in 
Subtitle I (discussed below).  
As discussed above, RCRA in practice is largely enforced by state agencies exercising state 
authority equivalent to the federal. EPA retains the power to undertake enforcement in such 
authorized states, however: the act requires only that the Administrator give notice to the state in 
which a violation has occurred prior to issuing an order or commencing a civil action. 
RCRA also provides for citizen suits (discussed below, under “Solid Waste Management 
Requirements”) both against persons and entities alleged to have violated standards or permit 
requirements and against EPA in cases where the Administrator has failed to perform an action 
that is nondiscretionary under the act. 
Solid Waste Management Requirements 
Solid wastes that are neither a listed nor a characteristic hazardous waste, or wastes that are not 
specifically exempted from regulation as a hazardous waste, are regulated under Subtitle D of 
RCRA. In contrast to its authority under Subtitle C, EPA’s authority to regulate solid waste 
disposal under Subtitle D is limited. Instead, Subtitle D establishes state and local governments as 
the primary planning, regulating, and implementing entities for the management of non-
hazardous solid waste, such as household garbage and non-hazardous industrial solid waste.31  
Under the authority of Sections 1008(a)(3) and 4004 of RCRA, EPA first promulgated “Criteria 
for Classification of Solid Waste Disposal Facilities and Practices” (40 C.F.R. 257).32 These 
regulations established minimum national performance standards necessary to ensure that “no 
reasonable probability of adverse effects on health or the environment” will result from solid 
waste disposal facilities or practices. Practices not complying with regulations specified under 40 
C.F.R. 257 constitute “open dumping” and are prohibited under RCRA. EPA does not have the 
authority to enforce that prohibition directly. Instead, states and citizens may enforce the 
prohibition on open dumping using the citizen suit authority under RCRA (discussed below under 
“Citizen Suits and Imminent Hazard Provisions”). EPA also may intervene if it is determined that 
waste disposal practices pose an imminent endangerment to human health or the environment 
(also discussed below).

Under HSWA, EPA was required to revise its existing criteria for evaluating whether solid waste 
management practices and facilities were conducting open dumping.33 Under HSWA, EPA was 
directed to establish criteria applicable to solid waste management facilities that may receive 
hazardous household waste and hazardous wastes from small quantity generators.34 Subsequently, 
EPA promulgated “Criteria for Municipal Solid Waste Landfills” (at 40 C.F.R. 258). Those 
regulations apply to landfills that receives household waste, that are not a “land application unit, 
surface impoundment, injection well, or waste pile.”35 The requirements include location 
restrictions, operation and design criteria (e.g., liner, leachate collection, run-off controls), 
groundwater monitoring and corrective action requirements, closure and post-closure care, and 
financial assurance criteria. EPA’s standards applicable to landfill operations (i.e., dry disposal 
systems) specifically exclude requirements applicable to surface impoundments (i.e., liquid waste 
ponds).  
Also required under HSWA, states were directed to implement a permit program to assure that 
solid waste management facilities that may receive municipal solid waste (MSW)36 complied 
with the revised landfill criteria. EPA was authorized to determine the adequacy of the state 
permit programs. Further, for states it determined did not have an adequate permit program, EPA 
was provided with inspection and enforcement authority under of Subtitle C to enforce the 
prohibition on open dumping.37  
Requirements applicable to MSW landfills do not apply to non-hazardous commercial or 
industrial waste landfills or construction and demolition waste landfills. Those disposal units are 
subject to requirements applicable to open dumping that are regulated at the state level. 
Under Subtitle D, solid waste provisions authorized under RCRA include financial and technical 
assistance for states and local governments. However, most such assistance ended in FY1981 due 
to overall budget cutbacks. 
Citizen Suits and Imminent Hazard Provisions 
As mentioned above, open dumping prohibitions, specified under the sanitary landfill regulations 
(40 C.F.R. 257), are enforced by states or through citizen suits. Citizen suit provisions specified 
under Section 7002 of RCRA allow for civil action against any entity that is alleged to be in 
violation of any “permit, standard, regulation, condition, requirement, prohibition, or order.”38 
Further, citizen suits are allowed where the disposal of any solid or hazardous waste may present 
“an imminent and substantial endangerment to health or the environment.”39 
                                                                  
33 Previously established under Sections 1008 and 4004 of RCRA. 
34 “Small quantity generators” (SQGs) are a category of hazardous waste generators. As specified under Section 
3001(d) of RCRA Subtitle C, SQGs are those that generate between 100 and 1,000 kilograms of hazardous waste 
during a calendar month. 
35 40 C.F.R. Part 258.2. 
36 The term “municipal solid waste” is referred to in the regulations, but not RCRA itself. In the law, it is referred to as 
“solid waste management facilities that may receive hazardous household waste or hazardous waste due to the 
provision of section 3001(d) for small quantity generators.”

In addition to citizen suit provisions, EPA is authorized to take action if past or present handling, 
storage, treatment transportation, or disposal of any solid or hazardous wastes may present an 
imminent and substantial endangerment to health or the environment.40 Under Section 7003 of 
RCRA, EPA can initiate judicial action or issue an administrative order to any past or present 
waste generator or owner of a disposal facility who has contributed or is contributing to the 
disposal. Section 7003 is available for use in several situations where other enforcement tools 
may not be available. For example, it can be used at sites and facilities that are not subject to 
Subtitle C of RCRA or any other environmental regulation. Specifically, action may be initiated if 
each of the following conditions is met:  
•  Conditions may present an imminent and substantial endangerment to health or 
the environment—such conditions generally require careful documentation and 
scientific evidence. However, the endangerment standard under RCRA has 
generally been broadly interpreted. 
•  The potential endangerment stems from the past or present handling, storage, 
treatment, transportation, or disposal of any solid or hazardous waste. 
•  The person has contributed or is contributing to such handling, storage, 
treatment, transportation, or disposal.41 
Under Section 7003, EPA may take action as deemed necessary, determined on a case-by-case 
basis. Further, it gives EPA authority to obtain relevant information regarding potential 
endangerments. 
Underground Storage Tanks 
To address a nationwide problem of leaking underground storage tanks (USTs), Congress 
established a leak prevention, detection, and cleanup program through the 1984 RCRA 
amendments and the 1986 Superfund Amendments and Reauthorization Act (SARA). 
The 1984 RCRA amendments created a federal program to regulate USTs containing petroleum 
and hazardous chemicals to limit corrosion and structural defects, and thus minimize future tank 
leaks. The law directed EPA to set operating requirements and technical standards for tank design 
and installation, leak detection, spill and overfill control, corrective action, and tank closure. The 
UST program (RCRA Subtitle I) is administered primarily by states. It requires registration of 
most underground tanks, bans the installation of unprotected tanks, sets federal technical 
standards for all tanks, coordinates federal and state regulatory efforts, and provides for federal 
inspection and enforcement. 
In 1986, Congress created a petroleum UST response program by amending Subtitle I of RCRA 
through SARA (P.L. 99-499). Prior to SARA, EPA lacked explicit authority to clean up 
contamination from leaking underground petroleum tanks as Congress had specifically excluded 
petroleum products (although not petrochemicals) from the Superfund law. The 1986 provisions 
authorized the federal government to respond to petroleum spills and leaks, and created a Leaking 
                                                                  
40 42 U.S.C. §6973.

of RCRA,” October 1997, available at http://www.p2pays.org/ref/03/02645.pdf. For information on legal requirements 
for initiating action under Section 7003, in particular, see pp. 9-19.

Underground Storage Tank (LUST) Trust Fund to fund cleanup of leaks from petroleum USTs in 
cases where the UST owner or operator does not clean up a site. The LUST Trust Fund provides 
money for EPA to administer the program and for states to oversee cleanups, take enforcement 
actions, and undertake cleanups themselves when necessary. The money in the fund is derived 
primarily from a 0.1 cent-per-gallon federal tax on motor fuels and several other petroleum 
products. 
The 1986 amendments also directed EPA to establish financial responsibility requirements for 
UST owners and operators to cover costs of taking corrective action and to compensate third 
parties for injury and property damage caused by leaking tanks. The law required EPA to issue 
regulations requiring tank owners and operators selling petroleum products to demonstrate 
minimum financial responsibility. The regulations require insurance coverage of $1 million, or 
alternatively, owners and operators may rely on state assurance funds to demonstrate financial 
responsibility. 
The Energy Policy Act of 2005 (P.L. 109-58) included in Title XV, Subtitle B, The Underground 
Storage Tank Compliance Act (USTCA). This act amended Subtitle I of the Solid Waste Disposal 
Act to add new leak prevention and enforcement provisions to the UST regulatory program and 
impose new requirements on states, EPA, and tank owners. The USTCA requires EPA, and states 
that receive funding under Subtitle I, to conduct compliance inspections of all USTs at least once 
every three years. It also requires states to comply with EPA guidance prohibiting fuel delivery to 
ineligible tanks; develop training requirements for UST operators and individuals responsible for 
tank maintenance and spill response; prepare compliance reports on government-owned tanks in 
the state; and implement groundwater protection measures for UST manufacturers and installers. 
The act also directed EPA to develop and implement a strategy to address UST releases on tribal 
lands. 
The USTCA authorized the appropriation of $155 million annually for FY2006 through FY2011 
from the LUST Trust Fund for states to use to implement the new UST leak prevention 
requirements and to administer state programs. Congress also authorized trust fund appropriations 
of $200 million annually for FY2006 through FY2011, for EPA and states to administer the LUST 
corrective action program, and another $200 million annually for FY2006 through FY2011, 
specifically for addressing releases involving methyl tertiary butyl ether (MTBE) and other 
oxygenated fuels (e.g., ethanol). 
Promoting Recycling  
Considering the prominence of the terms “Resource Conservation” and “Recovery” in the title of 
the law itself, it would appear that requirements regarding waste recycling or reuse would be 
significant elements of RCRA. In fact, requirements to recycle are largely absent from the law. As 
a component in non-hazardous solid waste, decisions regarding recycling are left to states and 
local governments.  
The role RCRA has played in promoting recycling has been through funding research, 
development, and demonstration projects associated with solid waste management.42 However, 
authority for most research projects fell victim to budget cutbacks. Currently, a limited number of 
                                                                  
42 Under RCRA Subtitle H—Research, Development, and Demonstration Information.

Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
solid waste grants are available for development or pilot projects that promote waste reduction, 
recycled-content products, markets for recycled materials, or assist in the development of solid 
waste management plans. 
RCRA also promotes “closing the loop” on recycling by establishing a federal procurement 
program.43 The goal of the program is to stimulate markets for recycled products by requiring 
federal departments and agencies to “buy recycled.” EPA is required to designate products that 
are or can be made with recovered materials, and to recommend practices for buying these 
products. Once a product is designated, procuring agencies are required to purchase it with the 
highest recovered material content level practicable. EPA subsequently published 
“Comprehensive Procurement Guidelines” to assist federal agencies in meeting their procurement 
requirements.44 
Amendments to RCRA 
RCRA has been amended several times. Some of those amendments were noncontroversial 
additions clarifying portions of the law, correcting clerical errors in the text, or encouraging the 
recycling of certain solid wastes. The most significant sets of amendments occurred in 1980, 
1984, and 1992. 
Solid Waste Disposal Act Amendments of 1980  
The Solid Waste Disposal Act Amendments of 1980 amended RCRA in several ways. It was 
intended, in part, to provide EPA with stronger enforcement authority to address illegal dumping 
of hazardous waste. It also authorized funds to conduct an inventory of hazardous waste sites and 
extended RCRA authorizations for appropriations through FY1982. Amending language 
contained in Superfund, P.L. 96-510, established an Assistant Administrator for Solid Waste and 
Emergency Response at EPA. 
The 1980 amendments also included provisions that excluded the following large-volume astes 
from the definition of hazardous waste under Subtitle C of RCRA:  
•  waste generated primarily from the combustion of coal or other fossil fuels; 
•  solid waste from the extraction, beneficiation, and processing of ores and 
minerals, including phosphate rock and overburden from the mining of uranium 
ore; 
•  cement kiln dust; and 
•  wastes generated during the exploration, development, and production of crude 
oil, natural gas, and geothermal energy. 
At the time of the exclusion, these “special wastes” (as they were referred to by EPA) were 
believed to pose less risk to human health and the environment than the wastes being identified 
for regulation as hazardous waste. The amendments specified that the hazardous waste exclusion 
                                                                  
43 42 U.S.C. §6962.

would be held pending completion of a study and report to Congress by EPA for each waste 
category. The subsequent regulatory timeline and the determination of the appropriate waste 
management method for each category of special waste has been a complex and varied process.45 
To date, special wastes largely have been regulated at the state level. However, a large spill of 
coal combustion waste in December 2008 from a Tennessee Valley Authority facility in Kingston, 
TN, heightened interest in the extent to this waste should be regulated under RCRA.46  
To establish national standards intended to address risks associated with potential coal 
combustion waste (CCW) mismanagement, on June 21, 2010, EPA proposed two regulatory 
options to manage the waste. The first would draw on EPA’s existing authority to identify a waste 
as hazardous and regulate it under the waste management standards established under Subtitle C 
of the RCRA. The second option would establish regulations applicable to CCW disposal units 
under RCRA’s Subtitle D solid waste management requirements. Under Subtitle D, EPA does not 
have the authority to implement or enforce its proposed requirements. Instead, EPA would rely on 
states or citizen suits to enforce the new standards.47 The public comment period on this 
regulatory proposal closed on November 19, 2010. It received over 11,000 comments. EPA has 
not indicated when a final rule may be issued. 
The Used Oil Recycling Act of 1989 
In an effort to encourage used oil recycling, and in recognition of its potential threat to public 
health and the environment when reused or disposed of improperly, Congress enacted the Used 
Oil Recycling Act in 1980 (P.L. 96-463). The act amended RCRA by requiring EPA to study the 
hazards posed by used oil and to develop used oil management standards to protect human health 
and the environment. Subsequently, EPA established recycling regulations for used oil that are 
completely separate from the hazardous waste recycling standards (provisions under which used 
oil may otherwise be regulated). 
Since EPA’s used oil program is designed to encourage used oil recycling, the regulations include 
a “recycling presumption.”48 This is an assumption that all used oil that is generated will be 
recycled. The recycling presumption simplifies the used oil management system by enabling 
handlers to only comply with the used oil regulations, instead of the hazardous waste regulations. 
Only when the used oil is actually disposed of or sent for disposal must handlers determine 
whether or not the used oil exhibits a characteristic of hazardous waste and manage it in 
accordance with hazardous waste regulations. 
Hazardous and Solid Waste Amendments of 1984 
The most significant set of amendments to RCRA was the Hazardous and Solid Waste 
Amendments of 1984 (HSWA), a complex law with many detailed technical requirements. In 
addition to restrictions on land disposal, and the inclusion of small quantity generators (SQGs) in

Congressional Research Service 
58 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
the hazardous waste regulatory scheme that was summarized above, HSWA created the new 
regulatory program for underground storage tanks (see the above “Underground Storage Tanks” 
section of this report.) The amendments directed EPA to issue regulations governing those who 
produce, distribute, and use fuels produced from hazardous waste, including used oil. Under 
HSWA, hazardous waste facilities owned or operated by federal, state, or local government 
agencies must be inspected annually, and privately owned facilities must be inspected at least 
every two years. Each federal agency was required to submit to EPA an inventory of hazardous 
waste facilities it ever owned. 
The 1984 law also imposed on EPA a timetable for issuing or denying permits for TSDFs; 
required permits to be for fixed terms not exceeding 10 years; terminated in 1985 the “interim 
status” of land disposal facilities that existed prior to RCRA’s enactment, unless they met certain 
requirements; required permit applications to be accompanied by information regarding the 
potential for public exposure to hazardous substances in connection with the facility; and 
authorized EPA to issue experimental permits for facilities demonstrating new technologies. 
EPA’s enforcement powers were increased, the list of prohibited actions constituting crimes was 
expanded, penalties were increased, and the citizen suit provisions were expanded. Other 
provisions prohibited the export of hazardous waste unless the government of the receiving 
country formally consented to accept it; created an ombudsman’s office in EPA to deal with 
RCRA-associated complaints, grievances, and requests for information; and reauthorized RCRA 
through FY1988 at a level of about $250 million per year. 
HSWA also specified that owners or operators of TSDFs are responsible for investigating and, as 
necessary, cleaning up releases at or from their facilities, regardless of when the releases 
occurred. EPA refers to this cleanup of TSDFs under these statutory authorities as RCRA 
Corrective Action. 
Finally, HSWA called for a National Ground Water Commission to assess and report to Congress 
in two years on groundwater issues and contamination from hazardous wastes. The commission 
was never funded and never established, however. 
Federal Facility Compliance Act 
The third major set of amendments was the Federal Facility Compliance Act of 1992. This act 
specified in greater detail the extent to which federal facilities are subject to enforcement actions 
under RCRA, and waived the federal government’s sovereign immunity from prosecution under 
the statute. As a result, federal departments and agencies can be subject to enforcement through 
injunctions, administrative orders, and/or penalties for noncompliance. However, the limited 
ability of one federal agency to sue another can, in practice, affect the extent to which EPA itself 
may enforce the requirements of the statute against another federal agency. Furthermore, federal 
employees may be subject to criminal sanctions, including both fines and imprisonment under 
any federal or state solid or hazardous waste law. The act also contains special provisions 
applicable to mixtures of radioactive and hazardous waste at Department of Energy facilities and 
to munitions, military ships, and military sewage treatment facilities handling hazardous wastes. 
1996 Amendments 
The 104th Congress passed an additional set of amendments to RCRA, the Land Disposal 
Program Flexibility Act (P.L. 104-119). This act exempts hazardous waste from RCRA regulation 
Congressional Research Service 
59 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
if it is treated to a point where it no longer exhibits the characteristic that made it hazardous, and 
is subsequently disposed in a facility regulated under the Clean Water Act or in a Class I deep 
injection well regulated under the Safe Drinking Water Act. A second provision of the bill 
exempted small landfills located in arid or remote areas from groundwater monitoring 
requirements, provided there is no evidence of groundwater contamination. 
Additional Selected Laws Affecting Solid Waste Management 
Although not technically amending RCRA, Congress has enacted various solid/hazardous waste-
related measures, which are briefly summarized below. 
Sanitary Food Transportation Act 
The Sanitary Food Transportation Act of 1990 (P.L. 101-500) required the regulation of trucks 
and rail cars that haul both food and solid waste (a problem commonly referred to as 
“backhauling of garbage”). The act directed the Departments of Agriculture, Health and Human 
Services, and Transportation to promulgate regulations specifying (1) record keeping and 
identification requirements; (2) decontamination procedures for refrigerated trucks and rail cars; 
and (3) materials for construction of tank trucks, cargo tanks, and ancillary equipment. 
Clean Air Act 
The Clean Air Act Amendments of 1990 (P.L. 101-549) contained a provision mandating stronger 
federal standards for solid waste incinerators. The law requires EPA to issue new source 
performance standards to control air emissions from municipal, hospital, and other commercial 
and industrial incinerators. New facilities must comply with the EPA rules within six months of 
the time they are issued, and existing units must comply within five years of issuance. 
Pollution Prevention Act 
The Pollution Prevention Act of 1990 (Sections 6601-6610 of P.L. 101-508) was passed as part of 
the Omnibus Budget Reconciliation Act of 1990. The measure declared pollution prevention to be 
the national policy, and directed EPA to undertake a series of activities aimed at preventing the 
generation of pollutants, rather than controlling pollutants after they are created. Matching grants 
were authorized for states to establish technical assistance programs for businesses, and EPA was 
directed to establish a Source Reduction Clearinghouse to disseminate information. The act also 
imposed new reporting requirements on industry. Firms that were required to file an annual toxic 
chemical release form under the Emergency Planning and Community Right-to-Know Act of 
1986 must also file a report detailing their source reduction and recycling efforts over the 
previous year. A more complete description of the act, which addresses air and water pollution as 
well as waste, is provided in the first section of this report. 
Indian Lands Open Dump Cleanup Act 
The Indian Lands Open Dump Cleanup Act of 1994 (P.L. 103-399) required the Indian Health 
Service (IHS) to provide technical and financial support to inventory and close open dumps on 
Indian lands, and to maintain the sites after closure. According to IHS, only two of more than 600 
waste dumps on Indian lands met current EPA regulations prior to the law’s enactment.

Mercury-Containing and Rechargeable Battery Management Act 
The 104th Congress passed legislation (P.L. 104-142) exempting battery collection and recycling 
programs from certain hazardous waste management requirements, prohibiting the use of mercury 
in batteries, and requiring labels on batteries to encourage proper disposal and recycling. By 
exempting battery collection and management programs from some parts of RCRA, the law was 
expected to stimulate new recycling programs.

Comprehensive Environmental Response, 
Compensation, and Liability Act49 
By the end of the 1970s, Congress had enacted several environmental laws to regulate sources of 
pollution in the United States, but had not yet addressed responsibility for contamination resulting 
from releases of pollutants into the environment. In the late 1970s, the discovery of severely 
contaminated sites, such as “Love Canal” in New York and Times Beach in Missouri, raised 
questions as to whether there should be a federal role in cleaning up environmental contamination 
to protect the public from potential harm. Congress enacted the Comprehensive Environmental 
Response, Compensation, and Liability Act of 1980 (CERCLA, P.L. 96-510) to authorize the 
federal government to clean up contaminated sites in the United States and to make the 
“potentially responsible parties” connected to those sites financially liable for the cleanup costs. 
CERCLA created the Superfund program to carry out these authorities. The Environmental 
Protection Agency (EPA) administers the program. Subsequent amendments to CERCLA also 
authorized EPA to administer a separate grant program to support the cleanup of abandoned or 
idled “brownfields” properties to encourage their redevelopment.  
CERCLA established a broad liability scheme that holds both past and current owners and 
operators of contaminated facilities financially responsible for the costs of cleanup. At waste 
disposal sites, generators of the waste sent to the site for disposal, and transporters of the waste 
who selected the site for disposal, also are responsible for the cleanup costs. If these potentially 
responsible parties cannot be found or cannot pay for the cleanup, CERCLA authorizes the 
federal government to finance the cleanup to ensure the protection of human health and the 
environment. These costs borne by the federal government are referred to as “orphan shares.” The 
broad liability scheme of CERCLA is intended to capture all parties that may have had some 
involvement in the actions that resulted in contamination of the environment, in order to 
minimize the burden of the costs of cleanup on the general taxpayer who had no involvement. 
This approach to liability is based on the principle that polluters should be required to pay for the 
environmental damage that they cause, often referred to as the “polluter pays principle.” 
CERCLA established the Hazardous Substance Superfund Trust Fund to finance cleanup actions 
taken by the federal government at contaminated sites where the potentially responsible parties 
cannot pay or cannot be found. A combination of special taxes on industry and revenues from the 
General Fund of the U.S. Treasury initially financed the Superfund Trust Fund, but the authority 
to collect the industry taxes expired at the end of 1995. As the remaining revenues were expended 
over time, Congress increased the contribution of general Treasury revenues in an effort to make 
up for the shortfall from the expired industry taxes. The availability of Superfund Trust Fund 
monies to finance the cleanup of contaminated sites is subject to appropriations by Congress. 
Considering the liability of the federal government as a potentially responsible party at its own 
facilities, the cleanup of federal facilities is not funded with Superfund Trust Fund monies under 
the Superfund program, but with other federal monies appropriated for other programs 
administered by the agencies responsible for these facilities. The Department of Defense (DOD)

Science, and Industry Division. 
Congressional Research Service

Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
and the Department of Energy (DOE) administer the cleanup of most contaminated federal 
facilities. EPA and the states are responsible for overseeing and enforcing the implementation of 
CERCLA at federal facilities to ensure that applicable requirements are met. 
To prioritize cleanup actions, CERCLA directed EPA to establish and maintain a National 
Priorities List (NPL) of the most contaminated sites in the United States which present the 
greatest risks to human health and the environment. The NPL includes both non-federal sites and 
federal facilities that are deemed to present a sufficient level of risk to warrant listing. EPA may 
require the potentially responsible parties to directly perform or pay for cleanup actions 
themselves. Alternatively, EPA may clean up a contaminated site up-front with appropriated 
Superfund monies and later recover those funds from the potentially responsible parties (with the 
exception of the cleanup of federal facilities which must be funded up-front by the administering 
agencies). In the event that the potentially responsible parties cannot pay or cannot be found, 
appropriated Superfund monies may be used to pay the orphan shares of cleanup costs at a site, 
under a cost-sharing agreement with the state in which the site is located. 
The following sections summarize the major cleanup authorities of CERCLA and other relevant 
provisions of the act. The topics discussed herein include the overall scope and reach of cleanup 
actions authorized under the statute, the process under which cleanup actions are selected and 
carried out at individual sites, the financial liability of potentially responsible parties for the costs 
of cleanup actions, the Superfund Trust Fund that may pay for cleanup actions when the 
potentially responsible parties cannot pay or cannot be found, enforcement of cleanup liability 
against the potentially responsible parties to minimize the need for federal tax revenues to finance 
the cleanup of contaminated sites, the applicability of CERCLA to federal facilities, and federal 
assistance for the cleanup of brownfields properties. A more in-depth examination of these 
statutory authorities is presented in CRS Report R41039, Comprehensive Environmental 
Response, Compensation, and Liability Act: A Summary of Superfund Cleanup Authorities and 
Related Provisions of the Act, by David M. Bearden. 
It should be emphasized that how and to what degree a specific contaminant at an individual site 
must be cleaned up under CERCLA are not specified in the law itself. The specific actions that 
are required to clean up contaminants at individual sites are determined on a site-by-site basis. 
Although CERCLA established a general process for making cleanup decisions, more specific 
direction is provided in EPA regulation and agency guidance. Other federal agencies that 
administer the cleanup of federal facilities under CERCLA have developed additional guidance 
documents that apply to their own respective facilities. Although the statutory authorities upon 
which federal agencies have based their cleanup regulations and guidance are discussed in this 
report, the content of these regulations and guidance is not examined here. 
Major Amendments 
Congress has amended CERCLA on numerous occasions to clarify the applicability of the 
cleanup authorities of the statute, and to provide relief from liability for certain categories of 
parties who may not have been involved in actions that led to contamination, or who may have 
contributed only certain quantities or types of waste to a site. Congress also has amended the 
statute to authorize federal assistance for the cleanup of abandoned or idled “brownfields” 
properties to encourage their redevelopment. Further, certain amendments have addressed unique 
cleanup challenges at federal facilities, such as the cleanup of unexploded ordnance on 
decommissioned military training ranges in the United States, and responsibility for the cleanup 
of contaminated federal property when it is transferred out of federal ownership. 
Congressional Research Service

Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
The Superfund Amendments and Reauthorization Act of 1986 (SARA, P.L. 99-499) clarified that 
federal facilities are subject to the cleanup requirements of CERCLA to the same extent as non-
federal entities, and amended various response, liability, and enforcement provisions of the law. 
The 1986 amendments also renewed the authorization of appropriations for EPA’s Superfund 
program through FY1991, and established a separate Defense Environmental Restoration 
Program within DOD to address contamination at active and decommissioned military facilities 
in the United States. Sections 311 and 312 of the National Defense Authorization Act for FY2002 
(P.L. 107-107) expanded the cleanup authorities of this program explicitly to include military 
munitions and related contamination on decommissioned military training ranges and munitions 
disposal sites in the United States. 
Title VI of the Omnibus Budget Reconciliation Act of 1990 (P.L. 101-508) extended the 
authorization of appropriations for EPA’s Superfund program through FY1994, and Title XI of 
that statute extended the authority to collect the special Superfund taxes on industry through 
December 31, 1995. Although reauthorizing legislation has been introduced in various 
Congresses, the taxing authority for the Superfund Trust Fund has not been renewed to date, nor 
has the authorization of appropriations for EPA’s Superfund program been extended. Instead, 
Congress has continued to fund the Superfund program primarily with general Treasury revenues 
through the annual appropriations process. Congress has annually authorized and appropriated 
funding for the Defense Environmental Restoration Program each year since its establishment. 
Most of this funding is supported with general Treasury revenues, with the exception of some 
revenues generated from the sale or lease of closed military bases which help fund their cleanup. 
In 1992, the Community Environmental Response Facilitation Act (P.L. 102-426) amended the 
federal facility provisions of CERCLA to facilitate the transfer of uncontaminated parcels of 
surplus federal property on which hazardous substances or petroleum products were not released. 
Section 334 of the National Defense Authorization Act for FY1997 (P.L. 104-201) further 
amended CERCLA to allow the transfer of contaminated surplus federal property before cleanup 
is complete, if certain assurances are provided to guarantee that the property will be cleaned up to 
a level that would be suitable for its intended use after transfer. 
Other amendments have attempted to address the fairness of the liability scheme of CERCLA, 
either by limiting or eliminating the liability of certain categories of parties. In 1996, the Asset 
Conservation, Lender Liability, and Deposit Insurance Protection Act (Subtitle E, Title II, 
Division A of P.L. 104-208) amended CERCLA to protect certain fiduciaries and financial lenders 
from liability. In 1999, the Superfund Recycling Equity Act (Title VI, Appendix I of P.L. 106-
113) exempted generators and transporters of recyclable scrap materials from cleanup liability 
under CERCLA, if the person who received the materials disposed of them instead and the 
disposal resulted in contamination. There had been some concern that the potential liability of 
generators and transporters under CERCLA could be a deterrent to recycling. 
In 2002, the Small Business Liability Relief and Brownfields Revitalization Act (P.L. 107-118) 
provided relief from cleanup liability for: (1) persons who contributed very small quantities of 
waste or only municipal solid (i.e. non-hazardous) waste to a site, (2) owners of property that 
became contaminated merely as a result of migration from a contiguous property owned by 
another person, and (3) “bona fide” prospective purchasers who otherwise may be hesitant to 
acquire a contaminated property because of potential cleanup liability once acquiring ownership. 
The 2002 act also established more specific criteria for exempting “innocent” owners of 
contaminated property from cleanup liability, if they purchased the property without knowledge 
of the existing contamination and they had no involvement in actions that led to contamination. 
Congressional Research Service 
67 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
Persons seeking an exemption from liability as a “bona fide” prospective purchaser, contiguous 
property owner, or “innocent” landowner must have performed “all appropriate inquiry” into the 
prior uses of the property before acquiring ownership, and must take “reasonable steps” after 
acquiring ownership to prevent potentially harmful exposure to environmental contamination on 
their properties. Consequently, such persons still may bear some responsibility, even though they 
may be exempt from the more extensive liability scheme of CERCLA.  
In addition to providing relief from liability for certain categories of parties, P.L. 107-118 
authorized federal grants to assist in the cleanup of “brownfields” properties. Brownfields 
properties typically are abandoned, underutilized, or idled sites where the known or suspected 
presence of contamination, and the potential for cleanup liability, could be viewed as a deterrent 
to purchase the property for redevelopment. Brownfields properties tend to be less contaminated 
than sites listed on the NPL, but may need some cleanup to make them suitable for reuse. EPA 
originally had established a program in 1993 to provide federal assistance for the cleanup of 
brownfields properties using the general cleanup authorities of CERCLA as the legal basis for this 
assistance. P.L. 107-118 provided explicit statutory authority for this purpose, and established a 
separate Brownfields grant program within EPA, apart from the Superfund program. 
Table 12 lists CERCLA as enacted in 1980 and the major amendments to the law noted above.

Federal Response Authorities 
Section 104(a) of CERCLA specifically authorizes the President to respond to a release (or 
substantial threat of a release) of a hazardous substance into the environment, or of a pollutant or 
contaminant which may present an “imminent and substantial danger to the public health or 
welfare.”50 As authorized by Section 115 of CERCLA,51 the President delegated the response 
authorities of CERCLA to EPA and other federal agencies by executive order.52 EPA may respond 
to releases within the inland zone, and the U.S. Coast Guard may respond to releases within the 
coastal zone, which includes inland river ports and harbors, the Great Lakes, and U.S. coastal 
waters. If a release were to occur at a federal facility, the agency that administers the facility is 
authorized to take response actions, subject to oversight and enforcement by EPA and the state in 
which the facility is located. Federal funding to carry out response actions under CERCLA is 
subject to appropriations by Congress. 
Notification of a release of a hazardous substance is the action that may trigger a federal response 
under CERCLA. Section 103(a) requires the party responsible for a release to notify the National 
Response Center if the quantity of the release exceeds the regulatory limit established for that 
particular substance.53 These limits are referred to as “reportable quantities,” which are specified 
in federal regulation.54 State or local officials, or members of the public, who observe or suspect a 
release of a hazardous substance also may report the incident. Once a release is reported, the 
National Response Center is to notify the appropriate federal agency that would be responsible 
for carrying out the President’s response authorities under Section 104(a), and for taking any 
federal enforcement actions that may be necessary against the parties responsible for the release. 
Response actions taken under CERCLA most often entail cleanup activities involving the 
containment, removal, or treatment of environmental contamination to prevent potentially 
harmful exposure, but may include the temporary or permanent relocation of potentially exposed 
individuals if warranted. Congress has excluded certain types of environmental contamination 
from the response authorities of CERCLA, which may be addressed under other federal 
environmental laws. These exclusions are provided within the statutory definitions of key terms 
upon which the response authorities of CERCLA hinge, including the terms “hazardous 
substance,” “pollutant or contaminant,” and “release.” In addition to these exclusions, Congress 
has placed general limitations on the extent to which response actions may be taken under 
CERCLA to address releases of hazardous substances, pollutants, or contaminants in certain 
situations. In effect, these exclusions and limitations may restrict the applicability or scope of the 
response authorities of CERCLA at a particular contaminated site.

Petroleum Exclusion and Related Oil Pollution Act Authorities 
The response authorities of CERCLA do not extend to releases of petroleum. Section 101(14) of 
CERCLA generally excludes releases of petroleum, including crude oil and any fraction thereof, 
from the definition of a “hazardous substance” for the purposes of the statute. Section 101(33) 
does the same for the definition of “pollutant or contaminant.” Petroleum releases are covered 
instead by other statutes, which in effect serve as a complement or companion to the response 
authorities of CERCLA. The Oil Pollution Act of 1990 (P.L. 101-380) is the primary federal law 
that addresses releases of petroleum. The response authorities of the Oil Pollution Act are rooted 
in Section 311(c) of the Clean Water Act, which authorizes federal actions to respond to releases 
of petroleum into or on the navigable waters of the United States and adjoining shorelines. 
Similar to the response authorities of CERCLA, EPA is the delegated lead for the cleanup of oil 
spills that occur within the inland zone, and the U.S. Coast Guard leads the cleanup of oil spills 
that occur within the coastal zone. Section 9003(h) of the Solid Waste Disposal Act provides 
additional federal response authorities for petroleum leaked from underground tanks. In practice, 
CERCLA has been applied to the cleanup of some wastes containing petroleum only if the wastes 
also contained hazardous substances that were not part of the petroleum product itself.  
Other Exclusions 
Section 101(22) of CERCLA also excludes certain types of releases from the definition of the 
term “release,” thereby removing such releases from the statute’s reach. A specific category of 
nuclear materials is excluded from the definition of release, including “source, byproduct, or 
special nuclear material” released from a nuclear incident or at certain uranium processing sites. 
The disposal and cleanup of these materials are subject to the Atomic Energy Act and the 
Uranium Mill Tailings Radiation Control Act. With the exception of these specific nuclear 
materials, CERCLA generally applies to the release of radionuclides. In federal regulation, EPA 
has designated several hundred radionuclides as hazardous substances that are subject to the 
authorities of CERCLA. Section 101(22) also excludes three other types of releases from the 
response authorities of CERCLA: (1) a release that would result in exposure solely within the 
workplace; (2) emissions from engine exhaust of a motor vehicle, train, aircraft, vessel, or power 
pumping station; and (3) the “normal” application of fertilizer. 
Limitations on Response Actions 
Section 104(a)(3) limits the extent to which actions may be taken under CERCLA to respond to 
releases of hazardous substances, pollutants, or contaminants in certain situations. Response 
actions generally may not be taken in situations involving: (1) releases of naturally occurring 
substances in their unaltered form; (2) releases from products (such as asbestos) that are part of a 
residential, business, or community structure or building; or (3) releases into public or private 
drinking water supplies due to deterioration of supply systems through ordinary use. However, in 
the event of a public health or environmental emergency declared by the President, CERCLA 
authorizes response actions to be taken under the statute in any of these three situations, if no 
other person has the authority and capability to respond in a timely manner. 
Prioritization of Response Actions 
Section 105(a) of CERCLA requires the President to develop a National Priorities List (NPL) of 
the most hazardous sites in the United States to prioritize response actions. The President has 
Congressional Research Service 
70 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
delegated this task to EPA. The NPL must be updated at least annually. Section 105(c) requires 
the use of a Hazard Ranking System (HRS) to determine which sites warrant placement on the 
NPL. The system scores each site based on certain factors, such as the quantity and nature of 
hazardous substances; the likelihood of the migration of contamination in groundwater, surface 
water, and air; and the proximity to human populations and sensitive environments. Because of 
this range of factors, the severity of contamination alone may not necessarily be sufficient cause 
to list a site on the NPL. For example, a geographically isolated site with substantial 
contamination still may not score highly enough on the HRS to warrant placement on the NPL, if 
the distance from human populations prevents the likelihood of exposure. 
Section 105(a) of CERCLA also required the President to develop a National Hazardous 
Substance Response Plan to establish procedures and standards for responding to releases of 
hazardous substances, pollutants, and contaminants into the environment. The law directed the 
President to incorporate these procedures and standards into the National Oil and Hazardous 
Substances Pollution Contingency Plan (referred to as the National Contingency Plan for short, or 
NCP). As delegated by the President, EPA promulgated the National Hazardous Substance 
Response Plan in federal regulation as part of the NCP. These regulations govern any response 
actions taken under CERCLA. 
Scope of Response Actions 
CERCLA authorizes two types of response actions: “removal” and “remedial” actions. These 
terms are defined in Sections 101(23) and 101(24) of CERCLA respectively. Removal does not 
necessarily mean the physical removal of contamination from the soil, surface water, or 
groundwater, and remedial actions do not necessarily involve treatment of contamination. Rather, 
both actions may involve various methods to prevent exposure to contamination, including the 
relocation of potentially exposed individuals if warranted. It should be noted that the NCP allows 
remedial actions to be financed with Superfund monies only at sites listed on the NPL, whereas 
removal actions may be financed with Superfund monies at non-NPL sites to address emergency 
situations. This restriction is intended to reserve Superfund monies for costlier remedial actions at 
NPL sites that are thought to present the greatest risks. This funding restriction in the regulations 
is based on the statutory requirement of Section 105(a) of CERCLA for EPA to prioritize 
contaminated sites for the purpose of taking remedial actions. 
Removal actions tend to be shorter term actions that address more immediate risks, whereas 
remedial actions tend to be longer term actions that offer a more permanent solution. As such, 
remedial actions often entail more extensive and costly measures. Because of the typically greater 
extent and cost of remedial actions, they are subject to more in-depth review in the form of a 
Remedial Investigation and Feasibility Study (RI/FS). An RI/FS involves an investigation of the 
contamination to assess potential risks of exposure and a study of the feasibility of remedial 
alternatives to address those risks. Remedial actions also are subject to public participation 
requirements under Section 117 of CERCLA. (See the “Public Participation” section of this 
report.) Removal actions are not subject to a similar degree of review or public comment because 
of the perceived need for swifter response to address more immediate risks. 
Section 104(c)(1) generally restricts the timing of removal actions funded with Superfund monies 
to one year and the cost to $2 million, with exceptions provided in certain situations. For 
example, a remedial action may exceed these limitations if the continuance of the removal action 
would contribute to the remedial action planned at the site. These general timing and cost

limitations on removal actions are intended to ensure that removal actions are not pursued on a 
broader scale as a way to avoid the more in-depth review required of remedial actions. 
However, CERCLA does not impose these limitations on a removal action funded by a 
responsible party with its own funds, nor by a federal agency at a federal facility with dedicated 
monies appropriated to that agency for that purpose apart from Superfund. From a practical 
standpoint, imposing the above timing and cost limitations on removal actions at many federal 
facilities administered by the Department of Defense and Department of Energy could constrain 
the needed scope of removal actions, as cleanup challenges are often greater at these federal 
facilities in comparison to non-federal sites. 
Federal-State Cost Sharing 
Section 104(c)(3) of CERCLA requires the state in which a non-federal NPL site is located to 
agree to share the costs of remedial actions at that site, as a condition of obligating federal 
Superfund monies to finance those actions. States are not responsible for sharing the costs of 
cleanup at sites where the potentially responsible parties pay for the cleanup, including federal 
facilities that are funded by the federal agencies that administer them. Rather, the federal 
government and the states are to share the costs of assuming the responsibility for the orphan 
shares of the cleanup costs, for which there are no viable parties to pursue. 
This cost-sharing requirement in Section 104(c)(3) is intended to reduce the financial burden on 
the federal taxpayer presented by the often long-term financial commitment involved in carrying 
out a remedial action. Notably, CERCLA does not require states to agree to share the costs of 
removal actions, which typically are less costly as a result of their smaller scope. Consequently, 
federal Superfund monies may be used to finance the entire costs of removal actions. 
At a site where the state must agree to share the costs of remedial actions as a condition of the 
obligation of federal Superfund monies, the state first must provide certain assurances of its 
financial commitments, specified in a binding contract or cooperative agreement with the federal 
government. Absent such contract or agreement, federal Superfund monies are not available to 
finance remedial actions at that site. To allow the obligation of federal Superfund monies to 
commence the remedial actions, the state must agree to pay 10% of the costs of those actions. If 
the site was owned or operated by the state, or a political subdivision of the state, at the time of 
disposal, the state must agree to pay at least 50% of the costs of the remedial actions. 
In addition to the above conditions, the state must agree to perform future maintenance of the 
remedial actions for their expected operational life. The point of maintenance usually occurs after 
any necessary construction is complete and the remedial action is operating as intended. 
CERCLA authorizes a delay in the state’s responsibility for the maintenance of groundwater or 
surface water remedies. Section 104(c)(6) allows a state to delay its maintenance responsibilities 
for the first 10 years of the operation of such remedial actions. The statute allows a delay in the 
state’s maintenance responsibility specifically for these types of actions to reduce the burden of 
those costs on the state, as the cleanup of groundwater or surface water tends to be more costly 
than other types of remediation. During the initial 10-year period, federal Superfund monies 
instead can be used to pay the maintenance costs of groundwater or surface water remedies.

Selection of Response Actions 
Section 121(a) of CERCLA generally requires response actions at contaminated sites to achieve 
acceptable levels of exposure that would be protective of human health and the environment. 
Response actions also are to be cost-effective over both the short term and long term, including 
the operation and maintenance of the action. Section 121(b) states a preference for the selection 
of remedial actions that involve treatment to “permanently and significantly” reduce the “volume, 
toxicity or mobility” of contamination, as opposed to actions that do not involve such treatment.  
Actions not involving treatment often entail the containment of wastes on-site, or the removal and 
disposal of wastes off-site. The containment of wastes on-site could present lingering health and 
environmental risks if the containment method were to fail over time. If the remedial action 
would result in wastes being left on-site, Section 121(c) requires the President to review the 
performance of the remedial action every five years to determine whether that action continues to 
be protective of human health and the environment. If the action is not functioning as intended, 
the President may take additional remedial actions at the site to achieve the cleanup goal. 
Although Section 121 includes certain requirements to govern the selection of remedial actions, it 
does not specify how clean an individual site must be to protect human health and the 
environment. Section 121 also does not identify the specific nature of the remedial actions that 
would be required to attain a cleanup goal at an individual site. Instead, these cleanup decisions 
are made on a site-by-site basis taking many factors into consideration, including the potential for 
human exposure based on the anticipated land use, and the technical and economic feasibility of 
cleanup alternatives to prevent exposure.  
Cleanup Standards 
The level of cleanup that is required can vary widely from site to site depending on the 
contaminants present, the cleanup standards or criteria that apply to those contaminants, and the 
response actions selected to attain those standards or criteria. Rather than specify standards or 
criteria for individual hazardous substances, Section 121(d) of CERCLA broadly requires that 
cleanup comply with applicable, relevant, and appropriate requirements (ARARs) to protect 
human health and the environment. ARARs can include a host of federal or state standards, 
requirements, or other criteria. In this sense, CERCLA functions as an “umbrella” statute under 
which other statutes or regulations also may be applied to the cleanup of a contaminated site. 
Section 121(d)(4) authorizes the waiver of a particular standard, if: 
•  the contemplated response action would be part of a larger remedial action that 
would meet the standard once the larger action is completed; 
•  compliance with the standard would result in a greater risk than the alternatives; 
•  compliance with the standard would be technically impracticable from an 
engineering perspective; 
•  an equivalent standard of performance would be attained; 
•  in the case of a state standard, the state has not consistently applied that standard 
elsewhere within its jurisdiction; or 
Congressional Research Service 
73 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
•  meeting the standard would not provide a balance between the need for 
protection of public health and welfare and the environment at the site under 
consideration, and the availability of monies in the Superfund Trust Fund to 
respond to more immediate risks at other sites.  
Although CERCLA generally does not list specific standards that may apply to the cleanup of an 
individual site, there are two sets of standards cited in Section 121(d) that broadly apply to the 
selection of remedial actions at any site. First, the law requires remedial actions to achieve a level 
of cleanup that would attain Maximum Contaminant Levels (MCLs) established for current or 
potential sources of drinking water under the Safe Drinking Water Act. Second, remedial actions 
must be consistent with other water quality criteria established under Sections 303 or 304 of the 
Clean Water Act. However, the applicability of these sets of standards to an individual site 
remains limited to circumstances in which the standards still are deemed “relevant and 
appropriate,” consistent with the underlying premise of an ARAR. 
State Participation 
CERCLA authorizes a broad role for states to participate in the cleanup process. States must agree 
to share in the costs of remedial actions at non-federal NPL sites as a condition of the obligation 
of federal Superfund monies. In acknowledgment of their sharing of the costs of cleanup, Section 
121(f) of CERCLA requires that states be afforded opportunities for “substantial and meaningful 
involvement” in initiating, developing, and selecting remedial actions. However, there are certain 
limitations on the involvement of states in cleanup decisions at federal facilities, as states do not 
share in the costs of cleanup at these facilities. If a state wishes to challenge a remedial decision 
of a federal agency at a facility which that agency administers, Section 121(f)(3) requires that the 
state show that the decision of the agency is not supported by “substantial evidence.”  
Public Participation 
CERCLA also provides a role for the general public in commenting on the selection of remedial 
actions at individual sites. This role is similar to that under many other federal laws that require 
the opportunity for the public to comment on certain types of federal decisions. Section 117 of 
CERCLA requires EPA, or other federal agency responsible for administering and funding the 
cleanup of a contaminated site, to provide the public an opportunity to comment on proposals for 
the selection of remedial actions. Once a final decision is made, public notice of the decision must 
be provided, with an explanation of any “significant” differences from the proposed action and a 
response to each “significant” public comment on the proposed action. 
The opportunity for public comment required by Section 117 of CERCLA applies only to 
decisions on remedial actions. Decisions on removal actions are not subject to these requirements 
because of the presumed need for expedited action to address more immediate risks. In practice, 
EPA and other federal agencies typically notify the public of the selection of removal actions to 
inform communities of the nature and timing of such actions. To assist the public in 
understanding technical information presented in cleanup decision documents, Section 117(e) of 
CERCLA authorizes technical assistance grants of up to $50,000 for community groups. These 
grants are available only to affected communities at sites listed on the NPL.

Agency for Toxic Substances and Disease Registry 
Section 104(i) of CERCLA established the Agency for Toxic Substances and Disease Registry 
(ATSDR) primarily to assess potential health risks at NPL sites. The ATSDR assesses individual 
sites based on the likelihood of human exposure to contamination through the air, soil, surface 
water, groundwater, and other pathways such as consumption of contaminated food sources. The 
purpose of these assessments is two-fold: to inform the public of potential health hazards at a 
contaminated site, and to aid decision-makers in evaluating what cleanup actions may be 
warranted to prevent potentially harmful exposure. Although the findings of the ATSDR may be 
used to inform the selection of cleanup actions, the agency does not have any authority to dictate 
cleanup decisions. In addition to site-specific assessments, Section 104(i) directs the ATSDR to 
prepare toxicological profiles of hazardous substances commonly found at NPL sites to identify 
potential health effects that can result from exposure.  
Section 104(i) of CERCLA also authorizes the ATSDR to carry out several other functions 
intended to protect public health. For example, the agency is authorized to provide medical care 
and testing to individuals in the event of a public health emergency caused by, or believed to be 
caused by, exposure to toxic substances. CERCLA does not provide any criteria as to what 
constitutes a public health emergency for this purpose, presumably leaving the declaration of such 
an emergency to the discretion of the ATSDR. As with other roles, the resources of the agency to 
fulfill this role are subject to appropriations by Congress. To date, the ATSDR has not used its 
authority under CERCLA to declare a public health emergency. In practice, the agency’s role has 
focused on educating the public about known health risks from exposure to hazardous substances, 
and assessing potential risks at individual sites to aid in informing cleanup decisions. 
Financial Liability  
Section 107 of CERCLA identifies the categories of potentially responsible parties connected 
with a contaminated site who are liable for the costs of response actions that EPA deems 
necessary to protect human health and the environment. Such parties also are liable for damages 
for injury to, destruction of, or loss of natural resources resulting from a release of a hazardous 
substance, including the costs of assessing such injury, destruction, or loss; and the costs of public 
health assessments carried out by the ATSDR under Section 104(i) of CERCLA. The following 
sections discuss the categories of parties who are liable under Section 107 of CERCLA, the reach 
of liability, defenses to liability, and limitations on the liability of certain categories of parties. 
Categories of Potentially Responsible Parties 
Section 107(a) identifies four categories of potentially responsible parties who are liable for the 
costs of response actions, natural resource damages, and public health assessments associated 
with the release or threatened release of a hazardous substance: 
•  any person who currently owns or operates a facility or vessel from which a 
hazardous substance was released; 
•  any person who at the time of disposal of a hazardous substance owned or 
operated the facility at which such disposal occurred; 
Congressional Research Service 
75 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
•  any person who arranged for the disposal or treatment of a hazardous substance 
(often referred to as a generator of waste), and any person who arranged for the 
transport of a hazardous substance for disposal or treatment; and 
•  any person who accepts or accepted a hazardous substance for transport to a 
disposal or treatment facility, incineration vessel, or site selected by such person.  
With respect to liability, financial responsibility for cleanup costs may extend to actions beyond a 
facility boundary, if a hazardous substance were to migrate (i.e., move or spread) through the 
environment. Section 101(8) of CERCLA defines the term “environment” to include not only the 
land, but also surface water, groundwater, or ambient air. Consequently, cleanup actions may be 
necessary not only on the facility where the initial release occurred, but anywhere the hazardous 
substance may migrate through the environment. For example, hazardous substances that migrate 
into groundwater or surface water can travel some distance, even miles, and can necessitate 
cleanup actions across a larger area than where the release first occurred. 
Reach of Liability 
Over time, the courts have interpreted liability under Section 107 of CERCLA to be strict, joint 
and several, and retroactive. This judicial interpretation is rooted in case law, legislative history, 
and the definition of liability in Section 101(32) of CERCLA that applies the same standards of 
liability as in Section 311 of the Clean Water Act.  
•  Strict liability means that a party can be held liable regardless of whether the 
conduct of that party was negligent. 
•  Joint and several liability means that one or more of the liable parties can be held 
responsible for the full cost of the cleanup at a site, regardless of the degree of 
involvement in the contamination. However, Section 113(f)(1) of CERCLA 
allows a party to seek recovery of some of its cleanup costs from other parties at 
a site through contribution claims in court. In deciding such claims, a court is to 
base the allocation of cleanup costs on “equitable factors.” In the event that a 
party can show that the waste it sent to the site could not have contributed to the 
contamination, joint and several liability is not to apply to that party. 
•  Retroactive liability means that parties are liable for the cleanup of hazardous 
substances released prior to the enactment of CERCLA on December 11, 1980. 
However, Section 107(f)(1) extends liability for natural resource damages only to 
releases that occurred on or after the enactment of CERCLA, which resulted in 
injury to, destruction of, or loss of the natural resources.  
It should be emphasized that the above description of the basic liability standards of CERCLA 
merely offers a brief summary of the broad reach of the statute, as generally interpreted by the 
courts over time. As such, this description does not examine the complexities of individual court 
decisions on these matters. Since the enactment of CERCLA in 1980, well over one thousand 
court decisions have interpreted these basic liability standards under the statute to determine the 
financial responsibility of potentially responsible parties for the costs of cleanup. How a court 
may view the cleanup liability of an individual party at any one site would depend on numerous 
legal issues that are beyond the scope of the summary of CERCLA offered in this report. 
Congressional Research Service 
76 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
Defenses to Liability 
Section 107(b) of CERCLA provides defenses to liability under certain circumstances. A party 
cannot be held liable for the release or threatened release of a hazardous substance, and resulting 
injury to, destruction of, or loss of natural resources, if that party can provide evidence that the 
release or threatened release was caused solely by: 
•  an act of God; 
•  an act of war; 
•  an act or omission of a third party with whom the defendant has no contractual 
relationship, if the defendant exercised due care with respect to the hazardous 
substance and took precautions against foreseeable acts or omissions of that third 
party and against the foreseeable consequences of such acts or omissions; or 
•  any combination of these three circumstances. 
The third party defense sometimes is characterized as the “innocent” landowner defense, in the 
sense that it typically pertains to property owners who had no involvement in the actions that led 
to the contamination. Section 101(35) of CERCLA defines the term contractual relationship for 
the purpose of the third party defense, and specifies the conditions that a landowner must satisfy 
to claim the lack of a contractual relationship connecting the owner to the contamination. 
Limitations on Liability 
To address the fairness of the liability scheme of CERCLA, Congress has amended Section 107 
and other related provisions of the statute to limit, or in some cases eliminate, the liability of 
certain categories of parties who may not have been involved in actions that resulted in 
contamination, who may have contributed only very small quantities or less toxic wastes to a 
contaminated site, or whose conduct Congress did not wish to discourage. These categories of 
parties include: 
•  response action contractors who merely perform the work to clean up a 
contaminated site, but who did not cause or otherwise contribute to the 
contamination; 
•  state and local governments that acquired contaminated property involuntarily 
through bankruptcy, tax delinquency, abandonment, or other circumstances, and 
did not cause or otherwise contribute to the contamination; 
•  persons who only hold a contaminated property in a fiduciary capacity; 
•  financial lenders who acquire financial interests or ownership of a contaminated 
property through foreclosure; 
•  generators and transporters of scrap materials intended for recycling, but instead 
may have been disposed of by other persons; 
•  persons who contributed only very small quantities of waste or only municipal 
solid (i.e. non-hazardous) waste to a site; 
•  service station dealers who only disposed of recycled oil that was not 
contaminated with hazardous substances, and who fully complied with federal 
regulations for managing the recycled oil; 
Congressional Research Service 
77 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
•  “innocent” landowners who purchased a property without knowledge of existing 
contamination, with respect to the third party defense; 
•  other “innocent” owners of property that became contaminated merely through 
migration from a contiguous property where the initial release occurred; and 
•  “bona fide” prospective purchasers who otherwise may be hesitant to acquire a 
property on which contamination is known or suspected to be present, because of 
the potential liability for cleanup upon acquiring ownership. 
Hazardous Substance Superfund Trust Fund 
CERCLA established the Hazardous Substance Superfund Trust Fund to provide a source of 
funds for the federal government to finance the cleanup of contaminated sites where the 
potentially responsible parties cannot pay or cannot be identified. This assumption of financial 
responsibility for these “orphan shares” of cleanup costs is intended to ensure that the actions 
necessary to protect human health and the environment are carried out. The availability of 
Superfund Trust Fund monies to pay for the cleanup of orphaned sites is subject to appropriations 
by Congress. Once appropriated, the availability of Superfund monies under EPA’s Superfund 
program to pay for remedial actions is further subject to cost-sharing agreements with the states 
in which the sites are located, as discussed in the “State Participation” section of this report. 
Original Taxing Authority 
The special taxing authority to finance the Superfund Trust Fund expired at the end of 1995. 
Before this authority lapsed, three dedicated taxes on petroleum, chemical feedstocks (and 
imported chemical derivatives), and corporate income provided most of the revenues for the 
Superfund Trust Fund. Revenues from the General Fund of the U.S. Treasury also contributed to 
the trust fund to augment the dedicated taxes, but these general tax revenues were a relatively 
small portion of the total revenues to the trust fund during the time that the dedicated taxes were 
collected through the end of 1995. 
As originally enacted in 1980, Section 211(a) of CERCLA authorized the Superfund excise taxes 
on petroleum and chemical feedstocks. Section 515(a) of the Superfund Amendments and 
Reauthorization Act of 1986 expanded the reach of the chemical feedstocks tax to include 
imported chemical derivatives. Prior to expiration at the end of 1995, the Superfund excise tax on 
petroleum was 9.7 cents per barrel. The Superfund excise tax on chemical feedstocks and 
imported chemical derivatives varied from $0.22 per ton to $4.87 per ton, depending on the 
substance (with the exception of xylene which was taxed at a higher rate of $10.13 per ton in the 
initial years of the tax until 1992.) Section 516(a) of the Superfund Amendments and 
Reauthorization Act of 1986 established the special tax on corporate income to provide an 
additional revenue stream for the Superfund Trust Fund. Prior to expiration in 1995, the 
Superfund tax on corporate income (formally referred to as the Corporate Environmental Income 
Tax) was 0.12% of corporate alternative minimum taxable income in excess of $2 million. 
Congress created the Superfund taxes on petroleum and chemical feedstocks, based on the 
broadly held assumption that much of the environmental contamination in the United States had 
been caused as a result of industrial activities that involved these substances. The Superfund tax 
on corporate income was intended to raise additional revenues from a wide range of businesses 
that may have used or disposed of hazardous substances. However, some questioned the fairness 
Congressional Research Service 
78 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
of these taxes. Opponents highlighted that the income tax captured all businesses that met the 
income threshold, regardless of whether a business used or disposed of hazardous substances. 
Opponents also noted that not all petroleum and chemical companies were necessarily involved in 
actions that led to contamination. 
The appropriateness of the Superfund tax on petroleum was especially controversial in light of the 
exclusion of petroleum from the cleanup authorities of CERCLA. Because of this exclusion, 
monies from the Superfund Trust Fund have paid for the cleanup of petroleum contamination 
only if the contamination includes hazardous substances that are not part of the petroleum product 
itself. Congress has established other trust funds to address releases of petroleum. Title V of the 
Superfund Amendments and Reauthorization of 1986 created the Leaking Underground Storage 
Tank Trust Fund to pay for actions to respond to petroleum released from underground tanks. 
Title VIII of the Omnibus Budget Reconciliation Act of 1986 (P.L. 99-509) created the Oil Spill 
Liability Trust Fund to pay for actions to respond to surface releases of petroleum.  
Current Source of Revenues 
After the authority to collect the Superfund taxes expired, the remaining revenues from these 
taxes were expended by the end of FY2003, leaving revenues from the General Fund of the U.S. 
Treasury as the main source of monies for the Superfund Trust Fund. Although the Superfund 
taxes have expired, industry has continued to provide some of the funding for the trust fund via 
corporate income taxes that contribute to the General Fund. (Revenues to the General Fund 
consist of corporate income taxes, individual income taxes, and miscellaneous federal receipts 
and collections that are not dedicated to specific federal trust funds.) 
In addition to general Treasury revenues, others sources of monies have continued to contribute 
some revenues to the Superfund Trust Fund. Cleanup costs borne by the federal government that 
are later recouped from the potentially responsible parties are deposited into the trust fund 
(referred to as cost recoveries). These recouped funds can be made available for the cleanup of 
other sites where the potentially responsible parties cannot pay or cannot be found. Fines and 
penalties assessed against potentially responsible parties for violations of CERCLA are deposited 
into the trust fund as well. Interest also accrues on the trust fund balance. Collectively, these 
monies have been relatively small compared to the amount of general Treasury revenues that now 
support most of the trust fund. However, these other sources of monies do continue to help 
finance the trust fund, and to some extent reduce the need for general Treasury revenues at sites 
where the potentially responsible parties cannot be found or cannot pay.  
Enforcement Mechanisms 
There are three mechanisms through which the federal government can take actions to enforce 
cleanup liability under CERCLA, if the potentially responsible parties can be identified and have 
the financial capability to pay. These mechanisms include judicial or administrative orders under 
Section 106 of the statute requiring potentially responsible parties to perform cleanup actions, 
cost-recovery actions under Section 107 to recoup expenditures of Superfund monies from the 
potentially responsible parties for cleanup actions performed by the federal government, and 
voluntary settlement agreements with the potentially responsible parties under Section 122 to 
perform or pay for cleanup actions. Like the response authorities of CERCLA, these enforcement 
authorities are presidential authorities. As discussed earlier in this report, a 1987 executive order 
delegated the President’s response authorities under CERCLA to EPA and other federal agencies. 
Congressional Research Service 
79 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
This order also delegated the enforcement of the statute to EPA at sites on the land, and to the 
U.S. Coast Guard within inland river ports and harbors, the Great Lakes, and U.S. coastal waters. 
These agencies have the discretion to use any of the above mechanisms available under the law to 
enforce the cleanup liability of potentially responsible parties. In practice, the agencies typically 
attempt to negotiate voluntary settlement agreements with the potentially responsible parties first, 
and usually turn to the use of Section 106 orders or Section 107 cost-recovery actions when a 
negotiated settlement appears unlikely. Under a negotiated settlement, the agencies may take a 
party’s ability to pay into consideration when determining that party’s share of the cleanup costs. 
In the negotiation process, the party seeking the reduction must submit financial information to 
document whether its ability to pay may in fact be limited. The decision of the enforcing agency 
as to whether a reduced settlement is warranted is not subject to judicial review. However, a party 
only can pay for the cleanup to the extent it is indeed capable, to the point of bankruptcy. 
Reducing a party’s share of the cleanup costs based on its ability to pay is intended to avoid such 
financial outcomes as a consequence of cleanup liability. 
Although EPA and the U.S. Coast Guard are responsible for enforcing cleanup liability, Section 
310 of CERCLA authorizes citizens to challenge the adequacy of a cleanup action in court. The 
timing of a citizen suit for these purposes is limited under other provisions of the statute. Section 
113(h)(4) of CERCLA does not permit a citizen suit to be brought for violation of a cleanup 
requirement until the selected cleanup action at a site is completed. Further, a citizen suit may not 
be brought with regard to a removal action at a site where a remedial action is planned. These 
limitations on the timing of citizen suits are intended to allow the complete implementation of 
cleanup actions planned at a site, prior to subjecting the adequacy of those actions to judicial 
review to assess their compliance with CERCLA. 
Federal Facilities 
After CERCLA was enacted in 1980, questions arose as to whether Congress intended federal 
facilities owned and operated by the United States government to be subject to the cleanup 
requirements and liability provisions of the statute. As originally enacted, CERCLA was silent on 
this matter. Section 120 of the Superfund Amendments and Reauthorization Act of 1986 added 
Section 120 to CERCLA to clarify that federal facilities are subject to the cleanup requirements of 
the statute to the same extent as other entities, including the liability and enforcement provisions 
of the law. To comply with CERCLA, the federal agency with administrative jurisdiction over a 
facility is responsible for administering and paying for the cleanup of contamination out of its 
own budget, subject to appropriations by Congress. 
Section 111(e) of CERCLA explicitly prohibits the use of Superfund Trust Fund monies to clean 
up federal facilities, as these monies are dedicated to paying for the cleanup of sites where the 
potentially responsible parties cannot be identified or cannot pay. However, Section 111(e)(3) 
does allow the use of Superfund Trust Fund monies at an individual federal facility to provide 
alternative water supplies, if groundwater contamination has migrated beyond the boundary of 
that facility, and there are other potentially responsible parties connected to that facility in 
addition to the United States. In all other instances, Superfund Trust Fund monies are not 
available for the cleanup of federal facilities. 
As noted earlier in this report, the vast majority of contaminated federal facilities are 
administered by DOD and DOE. Congress has established dedicated appropriations accounts for 
each of these departments that are intended to fulfill the financial liability of the United States for 
Congressional Research Service 
80 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
the cleanup of the facilities that they administer. Section 211 of the Superfund Amendments and 
Reauthorization Act of 1986 specifically authorized a Defense Environmental Restoration 
Program within DOD to administer the cleanup of active and decommissioned military 
installations in the United States. Sections 311 and 312 of the National Defense Authorization Act 
for FY2002 (P.L. 107-107) expanded DOD’s cleanup authorities to include unexploded ordnance, 
discarded munitions, and munitions constituents (i.e., hazardous substances leached from 
munitions into the environment) on decommissioned training ranges and munitions disposal sites 
in the United States. Although Congress has not enacted similarly explicit cleanup program 
authorities for DOE, the department administratively established an Office of Environmental 
Management in 1989 to consolidate its cleanup efforts under CERCLA and other related statutory 
authorities, such as the Atomic Energy Act which governs the disposal of radioactive wastes. 
EPA and the states play a role in overseeing and enforcing the implementation of CERCLA at 
federal facilities administered by DOD and DOE under the above programs, as well as other 
contaminated federal facilities administered by other agencies. Section 120(e) of CERCLA 
explicitly requires EPA to take the lead in overseeing the cleanup of federal facilities listed on the 
NPL, but Section 120(f) of the statute allows states and local governments to participate in 
cleanup decisions. The states play a more prominent role in overseeing the cleanup of federal 
facilities not listed on the NPL. While CERCLA authorizes EPA and the states to oversee the 
cleanup of federal facilities, certain provisions of the law can limit their ability to direct or dictate 
how the cleanup process may be carried out at a federal facility. 
For example, Section 120(e)(4)(A) of CERCLA gives EPA final decision-making authority to 
select remedial actions at federal facilities listed on the NPL, but does not explicitly authorize 
EPA to direct the schedule of performing those actions, nor how those actions are to be operated 
and maintained over the long term to ensure their performance. These latter elements of the 
cleanup process at federal facilities would appear to be subject to negotiation among the agencies. 
Further, EPA’s enforcement of cleanup requirements at federal facilities through court actions is 
complicated by the limited ability of one federal agency to sue another. With respect to the 
participation of states and local governments, Section 120(f) of CERCLA requires the opportunity 
to be involved in cleanup decisions, but does not give states and local governments decision-
making authority similar to EPA’s authority at federal facilities on the NPL. In practice, these 
limitations may restrict the extent to which EPA, the states, and local governments may oversee 
the cleanup of federal facilities, even though Section 120 of CERCLA does require federal 
facilities to comply with cleanup requirements to the same extent as other entities. 
National Security Exemption 
Although Section 120 of CERCLA clarified the applicability of the statute to federal facilities, 
Section 120(j) authorized the President to exempt an individual federal facility from a 
requirement of CERCLA on a case-by-case basis if the exemption would be necessary to protect 
national security. This exemption is intended to prevent situations in which a federal facility may 
become unavailable for purposes essential to protecting national security, if carrying out a 
specific cleanup action somehow may interfere with those purposes. Section 120(j) specifically 
authorizes the President to exempt a federal facility administered by DOD or DOE from 
compliance with an individual requirement of CERCLA, if the President deems such an 
exemption necessary to protect national security. 
The President must notify Congress within 30 days of the issuance of an exemption and explain 
the reason for it. The time period of an exemption initially is limited to one year, but the President 
Congressional Research Service

Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
may renew it annually with notification to Congress. Historically, a national security exemption 
under Section 120(j) of CERCLA has not been invoked at any facility that DOD or DOE 
administers. Instead, contaminated facilities of both departments generally have been subject to 
the cleanup requirements of CERCLA. DOD and DOE have been responsible for carrying out 
these requirements at their respective facilities under the programs discussed above, with 
appropriations by Congress. However, there have been disagreements at some facilities as to what 
requirements may be applicable to their cleanup, and how certain requirements that are deemed 
applicable are to be satisfied to ensure the protection of human health and the environment. 
Brownfields Properties 
In 1993, EPA established an element within the Superfund program to assist communities with 
the cleanup of certain lower risk sites that did not warrant placement on the NPL, but at which 
cleanup was desired to encourage economic redevelopment. The purpose of the program was to 
provide federal financial assistance for the cleanup of properties referred to as “brownfields.” 
These properties typically are abandoned, idled, or underutilized, and on which known or 
suspected contamination is perceived as a deterrent to redevelopment by prospective purchasers 
who may be hesitant about becoming liable for cleanup once acquiring ownership. 
EPA initially used Superfund appropriations to provide “seed monies” to communities in the form 
of grants and loans to aid them in financing certain types of cleanup actions. Although there was 
broad support for this effort, some questioned EPA’s authority under CERCLA to use Superfund 
monies for the cleanup of these lower risk sites that were not listed on the NPL and that did not 
appear to warrant emergency removal actions under the Superfund program. Still, in the annual 
appropriations process, Congress set aside funding for brownfields cleanup assistance within the 
Superfund account for several years without specifically amending CERCLA for this purpose. 
In the 107th Congress, Subtitle A and Subtitle C of Title II of the Small Business Liability Relief 
and Brownfields Revitalization Act of 2002 (P.L. 107-118, hereinafter referred to as the 
“Brownfields Act”) amended CERCLA to provide explicit statutory authority for EPA to 
administer a Brownfields program separately from the Superfund program. The Brownfields Act 
authorized appropriations for this new program apart from appropriations for the Superfund 
account. There had been some concern about the diversion of Superfund appropriations away 
from addressing the greater human health and environmental risks at NPL sites. Still, the portion 
of Superfund appropriations that had been spent on the cleanup of brownfields properties was 
relatively small compared to the total appropriation. 
The program explicitly authorized in the Brownfields Act is similar in scope to the program that 
EPA had established in 1993, with the exception that the Brownfields Act allowed federal 
financial assistance for the cleanup of contamination resulting from releases of petroleum. As 
discussed earlier in the “Federal Response Authorities” section of this report, CERCLA otherwise 
does not apply to the cleanup of petroleum. The Brownfields Act also created two separate types 
of grants within the Brownfields program. One provides more direct financial assistance for the 
assessment and cleanup of individual properties. The other provides financial assistance to states 
and Indian tribes to aid them in carrying out their own cleanup programs, which in turn may assist 
in the cleanup of individual properties. In addition to these grant programs, Congress has enacted 
certain federal tax incentives through the Internal Revenue Code, which are intended to 
encourage the cleanup of brownfields properties.

Emergency Planning and Community Right-to-
Know Act55 
The Emergency Planning and Community Right-to-Know Act (EPCRA, codified at 42 U.S.C. 
11001-11050) was enacted in 1986 as Title III of the Superfund Amendments and Reauthorization 
Act (P.L. 99-499). EPCRA established state commissions and local committees to develop and 
implement procedures for coping with releases of hazardous chemicals, and mandated annual 
reporting to government officials on environmental releases of such chemicals by the facilities 
that manufacture or use them in significant amounts. EPA facilitates planning, enforces 
compliance when necessary, and provides public access to information about environmental 
releases of toxic chemicals. 
Subtitle A—Emergency Planning and Notification 
EPCRA established a national framework for EPA to mobilize local government officials, 
businesses, and other citizens to plan ahead for possible chemical accidents in their communities. 
Subtitle A requires local planning to respond to sudden releases of chemicals that might occur in 
the event of a spill, explosion, or fire. It is intended to ensure that responsible officials will know 
what hazardous chemicals are used or stored by local businesses and will be notified quickly in 
the event of an accident. 
Under Section 301, each state is required to create a State Emergency Response Commission 
(SERC), to designate emergency planning districts, and to establish local emergency planning 
committees (LEPCs) for each district. Section 302 requires EPA to list extremely hazardous 
substances and to establish threshold planning quantities for each substance. Originally, Congress 
defined chemicals as “extremely hazardous substances” if they appeared on a list EPA published 
in November 1985 as Appendix A in “Chemical Emergency Preparedness Program Interim 
Guidance.” However, EPA has authority to revise the list, and the threshold quantities of 
chemicals. Based on listing criteria, the intent appears to be to include only chemicals in 
quantities that could harm people exposed to them for only a short period of time. The law directs 
each facility to notify the LEPC for its district if it stores or uses any “extremely hazardous 
substance” in excess of its threshold planning quantity. 
Section 303 directs LEPCs to work with facilities handling specified “extremely hazardous 
substances” to develop response procedures, evacuation plans, and training programs for people 
who will be the first to respond in the event of an accident. Upon request, facility owners and 
operators are required to provide an LEPC with any additional information that it finds necessary 
to develop or implement an emergency plan. 
Section 304 requires that facilities immediately report a sudden release of any “extremely 
hazardous substance” or any “hazardous substance” (a much broader category of chemicals 
defined under CERCLA Section 102(a)) that exceeds the reportable quantity to appropriate state,

Science, and Industry Division. 
Congressional Research Service

local, and federal officials.56 Releases of a reportable quantity of a “hazardous substance” also 
must be reported to the National Response Center under CERCLA Section 103(a). (See the 
section above on “Hazardous Substance Superfund Trust Fund.”) 
Subtitle B—Reporting Requirements 
Subtitle B establishes various reporting requirements for facilities. The information collected may 
be used to develop and implement emergency plans, as well as to provide the public with general 
information about chemicals to which they may be exposed. 
The Occupational Health and Safety Act of 1970 (OSHAct) requires most employers to provide 
employees with access to a material safety data sheet (MSDS) for any “hazardous chemical.” 
This “right-to-know” law for workers aims to ensure that people potentially exposed to such 
chemicals have access to information about the potential health effects of exposure and how to 
avoid them. EPCRA, Section 311 requires facilities covered by OSHAct to submit an MSDS for 
each “hazardous chemical” or a list of such chemicals to the LEPC, the SERC, and the local fire 
department. EPA has authority to establish categories of health and physical hazards and to 
require facilities to list hazardous chemicals grouped by such categories in their reports. An 
MSDS need only be submitted once, unless there is a significant change in the information it 
contains. An MSDS must be provided in response to a request by an LEPC or a member of the 
public. “Hazardous chemicals” are defined by the Code of Federal Regulations, Title 29, at 
Section 1910.1200(c).57 
EPCRA, Section 312 requires the same employers to submit annually an emergency and 
hazardous chemical inventory form to the LEPC, SERC, and local fire department. These forms 
must provide estimates of the maximum amount of the chemicals present at the facility at any 
time during the preceding year; estimates of the average daily amount of chemicals present; and 
the general location of the chemicals in the facility.58 Information must be provided to the public 
in response to a written request. EPA is authorized to establish threshold quantities for chemicals 
below which facilities are not required to report. 
Section 313 mandates development of the Toxic Release Inventory (TRI), a computerized EPA 
database of “toxic chemical” releases to the environment by manufacturing facilities.59 It requires 
manufacturing facilities that manufacture, use, or process “toxic chemicals” to report annually to 
EPA on the amounts of each chemical released to each environmental medium (air, land, or water) 
or transferred off-site. EPA makes TRI data available in “raw” and summarized form to the 
                                                                  
56 Under CERCLA Section 102(a) a “hazardous substance” includes any “elements, compounds, mixtures, solutions, 
and substances which, when released into the environment may present a substantial danger to the public health or 
welfare or the environment.” Included in this definition are substances listed under the authority of any of the major 
environmental statutes (see CERCLA Section 101(14)). 
57 EPCRA excepts foods, food additives, and other substances regulated by the Food and Drug Administration; solids 
in a manufactured item to the extent exposure does not occur; substances used for personal or household purposes; 
substances used in research or hospitals; and substances used in routine agricultural operations. 
58 EPCRA allows facilities to report aggregate amounts of chemicals with similar health and environmental effects. 
This is called “Tier I” information. However, chemical specific information (“Tier II”) must be provided on request 
(under certain conditions) to a SERC, LEPC, fire department, or the public. 
59 “Toxic chemicals” are substances that may sicken people who are exposed to them in relatively small amounts by 
eating, drinking, breathing, or through skin absorption. The term “hazardous substance” is broader, including toxic 
chemicals, but also substances that are explosive, flammable, corrosive, or otherwise harmful. 
Congressional Research Service 
87

general public. The public may obtain specific information (e.g., about a particular manufacturing 
facility) by submitting a request in writing to EPA. EPA distributes written and electronic, 
nationwide and state-by-state summaries of annual data. Raw data and summaries also are 
available over the Internet.60 
EPCRA Section 313 generally requires a report to EPA and the state from each manufacturer with 
10 or more employees and who either uses 10,000 pounds or manufactures or processes 25,000 
pounds of any “toxic chemical” during the reporting year. However, EPA may adjust (and has 
adjusted in the past) these thresholds for classes of chemicals or categories of facilities. 
EPCRA enumerates the following data reporting requirements for each covered chemical present 
at each covered facility:61 
•  whether it is manufactured, processed, or otherwise used, and the general 
category of use; 
•  the maximum amount present at each location during the previous year; 
•  treatment or disposal methods used; and 
•  amount released to the environment or transferred off-site for treatment or 
disposal. 
EPCRA requires reporting by manufacturers, which the law defines as facilities in Standard 
Industrial Classification codes 20 through 39.62 The law authorized EPA to expand reporting 
requirements to additional industries. EPA promulgated a rule May 1, 1997, requiring reports on 
toxic releases from seven additional industrial categories, including some metal mining, coal 
mining, commercial electric utilities, petroleum bulk terminals, chemical wholesalers, and solvent 
recovery facilities (62 Federal Register 23834).63 
The original statute specified 313 “toxic chemicals” or categories of chemicals for which 
reporting was required, but EPCRA gave EPA authority to add or delete chemicals from the list 
either on its own initiative or in response to citizen petitions. EPA has removed more than 15 and 
added roughly 350 chemicals (or categories) to the original list. The listing criteria specified in 
Section 313(d)(2) authorize EPA to add a chemical when it is “known to cause or can reasonably 
be anticipated to cause” the following: 
•  “significant adverse acute human health effects at concentration levels that are 
reasonably likely to exist beyond facility site boundaries as a result of 
continuous, or frequently recurring, releases,”

the National Library of Medicine, at http://toxnet.nlm.nih.gov/cgi-bin/sis/htmlgen?TRI; or Right-to-Know Net, 
provided by OMB Watch at http://www.rtknet.org/. 
61 Congress added data submission requirements for manufacturers and processors of toxic substances when it enacted 
the Pollution Prevention Act of 1990 (see above). 
62 Standard Industrial Classification Codes were changed to North American Industry Classification System codes on 
March 21, 2003 (66 FR 13872-13887). 
63 Current regulations promulgated under EPCRA may be found at Title 40 in the Code of Federal Regulations, Part 
372.

•  “because of—(i) its toxicity, (ii) its toxicity and persistence in the environment, 
or (iii) its toxicity and tendency to bioaccumulate in the environment, a 
significant adverse effect on the environment of sufficient seriousness, in the 
judgment of the Administrator, to warrant reporting under this Section.” 
Subtitle C—General Provisions 
Subtitle C contains various general provisions, definitions, and authorizations. 
Trade Secrets 
Section 322 authorizes reporting facilities to withhold the identity of a chemical if it is a trade 
secret and they follow procedures established by EPA. 
Information for Health Professionals 
Special provisions are made in Section 323 for informing health professionals of a chemical 
identity that has been withheld to protect confidential business information, if the information is 
needed to diagnose or treat a person exposed to the chemical. 
Right to Know 
Section 324 directs EPA, governors, SERCS, and LEPCs to make emergency response plans, 
MSDSs, lists of chemicals, inventory forms, toxic chemical release forms, and follow up 
emergency notices available to the general public. 
Enforcement 
Section 325 establishes civil, administrative, and criminal penalties for non-compliance with 
mandatory provisions of the act. Citizens are given the authority to bring civil action against a 
facility, EPA, a governor, or an SERC by Section 326. 
Chemical Transport 
Chemicals being transported or stored incident to transport are not subject to EPCRA 
requirements, according to Section 327. 
Other Provisions 
Section 328 authorizes EPA to issue regulations. Definitions are provided in Section 329. Section 
330 authorizes to be appropriated “such sums as may be necessary” to carry out this title.

Pollution Prevention Act of 199064 
The Pollution Prevention Act of 1990 requires the Environmental Protection Agency to establish 
an Office of Pollution Prevention, develop and coordinate a pollution prevention strategy, and 
develop source reduction models. The act requires owners and operators of manufacturing 
facilities to report annually on source reduction and recycling activities, and authorizes EPA to 
collect data collection on pollution prevention. 
Background 
Enactment of the Pollution Prevention Act of 1990 marked a turning point in the direction of U.S. 
environmental protection policy. From an earlier focus on the need to reduce or repair 
environmental damage by controlling pollutants at the point where they are released to the 
environment, Congress enacted this law with the goal of achieving pollution prevention through 
reduced generation of pollutants at their point of origin. Broad support for this policy change was 
based on the notion that traditional approaches to pollution control had achieved progress, but 
may in the future be supplemented with new approaches that might better address cross-media 
pollution transfers, the need for cost-effective alternatives, and methods of controlling pollution 
from dispersed or nonpoint sources of pollution. 
Pollution prevention, also referred to as “source reduction,” is viewed by its advocates as the first 
in a hierarchy of options to reduce risks to human health and the environment. Where prevention 
is not possible or may not be cost-effective, other options would include recycling, followed next 
by waste treatment according to environmental standards, and as a last resort, safe disposal of 
waste residues. Source reduction is the preferred strategy for environmental protection because it 
often is cost-effective; offers industry substantial savings in reduced consumption of raw 
materials, pollution control costs, and liability costs; reduces risks to workers; and reduces risk to 
the environment and public health. 
In 1990, opportunities for source reduction appeared to be plentiful, but often were unrealized or 
rejected by industries without adequate consideration. The act was meant to increase interest in 
source reduction and encourage adoption of cost-effective source reduction practices. The law 
was enacted as Title VI of the Omnibus Budget Reconciliation Act of 1990, P.L. 101-508, and is 
codified as 42 U.S.C. 13101-13109. 
Provisions 
Section 6602(b) of the Pollution Prevention Act states that it is the policy of the United States that 
“pollution should be prevented or reduced at the source whenever feasible; pollution that cannot 
be prevented should be recycled in an environmentally safe manner, whenever feasible; pollution 
that cannot be prevented or recycled should be treated in an environmentally safe manner 
whenever feasible; and disposal or other release into the environment should be employed only as 
a last resort and should be conducted in an environmentally safe manner.”

Section 6603(5) defines source reduction as: 
any practice which— 
(i) reduces the amount of any hazardous substance, pollutant, or contaminant entering any 
waste stream or otherwise released into the environment (including fugitive emissions) prior 
to recycling, treatment, or disposal; and 
(ii) reduces the hazards to public health and the environment associated with the release of 
such substances, pollutants, or contaminants. 
Section 6604 of the act required EPA to establish an Office of Pollution Prevention. The office 
must be independent of the “single-medium program offices,” but was given authority to review 
and advise those offices to promote an integrated, multi-media (i.e., air, land, and water) approach 
to source reduction. EPA was directed to develop and implement a detailed and coordinated 
strategy to promote source reduction, to consider the effect on source reduction of all EPA 
programs and regulations, and to identify and make recommendations to Congress to eliminate 
barriers to source reduction. EPA also must conduct workshops and produce and disseminate 
guidance documents as part of a training program on source reduction opportunities for state and 
federal enforcement officers of environmental regulations. EPA’s strategy, issued in 1991, 
identifies goals, tasks, target dates, resources required, organizational responsibilities, and criteria 
to evaluate program progress. In addition, the act requires EPA to promote source reduction 
practices in other federal agencies and to identify opportunities to use federal procurement to 
encourage source reduction. 
To facilitate source reduction by industry, EPA is required under Section 6604 to develop, test, 
and disseminate model source reduction auditing procedures to highlight opportunities; promote 
research and development of source reduction techniques and processes with broad applicability; 
establish an annual award program to recognize innovative programs; establish a program under 
Section 6605 of state matching grants for programs to provide technical assistance to business; 
and disseminate information about source reduction techniques through a clearinghouse 
established in Section 6606. 
The act also includes provisions to improve data collection and public access to environmental 
data. Section 6604(b) directs EPA to develop improved methods of coordinating, streamlining and 
assuring access to data collected under all federal environmental statutes. An advisory panel of 
technical experts is established to advise the Administrator on ways to improve collection and 
dissemination of data. With respect to data collected under federal environmental statutes, Section 
6608 directs EPA to evaluate data gaps and data duplication as well as methods of coordinating, 
streamlining, and improving public access. 
Section 6607 requires owners and operators of many industrial facilities to report annually on 
their releases of toxic chemicals to the environment (under the Emergency Planning and 
Community Right-to-Know Act of 1986, Section 313). The Pollution Prevention Act requires 
these reports to include information about the facility’s efforts in source reduction and recycling. 
Specifically, reports must include 
•  the quantity of the toxic chemical entering any waste stream (or released to the 
environment) prior to recycling, treatment, or disposal; 
•  the quantity of toxic substance recycled (on- or off-site); 
Congressional Research Service 
92 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
•  the source reduction practices used; 
•  quantities of toxic chemical expected to enter waste streams and to be recycled in 
the two years following the year for which the report is prepared; 
•  ratio of production in the reporting year to production in the previous year; 
•  techniques used to identify opportunities for source reduction; 
•  amount of toxic chemical released in a catastrophic event, remedial action, or 
other one-time event; and 
•  amount of toxic chemical treated on- or off-site. 
All collected information is to be made available to the general public. 
Section 6607(c) of the Pollution Prevention Act provides enforcement authority under Title III of 
the Superfund Amendments and Reauthorization Act (also known as the Emergency Planning and 
Community Right-to-Know Act). Civil, administrative, and criminal penalties are authorized for 
non-compliance with mandatory provisions. Citizens are given the authority to bring civil action 
for non-compliance against a facility, EPA, a governor, or a State Emergency Response 
Commission. 
Section 6608(a) requires EPA to file a report on implementation of its Pollution Prevention 
Strategy biennially. The required contents of the reports are specified in the statute. 
Authorization for appropriations under the Pollution Prevention Act expired September 30, 1993, 
but appropriations have continued.

Toxic Substances Control Act65 
The Toxic Substances Control Act (TSCA, 15 U.S.C. 2601 et seq.) authorizes the EPA to screen 
existing and new chemicals used in U.S. manufacturing and commerce to identify potentially 
dangerous products or uses that should be subject to federal control. Both naturally occurring and 
synthetic chemicals are subject to TSCA, with the exception of chemicals regulated under other 
federal laws concerning food, drugs, cosmetics, firearms, ammunition, pesticides, tobacco, or 
mixtures. EPA may require manufacturers and processors of chemicals to conduct and report the 
results of tests to determine the effects of potentially dangerous chemicals on living things. Based 
on test results and other information, EPA must regulate the manufacture, importation, 
processing, distribution, use, and/or disposal of any chemical that presents an unreasonable risk of 
injury to human health or the environment. A variety of regulatory tools is available to EPA under 
TSCA ranging in severity from a total ban on production, import, and use to a requirement that a 
product bears a warning label at the point of sale. TSCA directs EPA to use the least burdensome 
option that can reduce risk to a level that is reasonable given the benefits provided by the 
chemical product or process.  
The original legislation included a single title, which has since been designated Title I. As 
enacted, TSCA included a provision requiring EPA to take specific measures to control the risks 
from polychlorinated biphenyls (PCBs) (Section 6(e)). Title I was amended in 2008 to restrict 
sales of elemental mercury (P.L. 110-414). In addition, five titles have been added to address 
specific concerns—asbestos in 1986 (Title II, P.L. 99-519), radon in 1988 (Title III, P.L. 100-
551), lead in 1992 (Title IV, P.L. 102-550), schools in 2007 (Title V, P.L. 110-140), and 
formaldehyde in 2010 (Title VI, P.L. 111-199). Title II directs EPA to set standards for asbestos 
mitigation in schools and requires asbestos contractors to be trained and certified. Title III directs 
EPA to provide technical assistance to states that choose to support radon monitoring and control. 
Title IV provides similar assistance with respect to abatement of lead-based paint hazards. Title V

addresses environmental issues at schools, including energy efficiency. Finally, Title VI 
establishes limits on emissions of formaldehyde from composite wood products. 
Background 
Federal legislation to control toxic substances was originally proposed in 1971 by the President’s 
Council on Environmental Quality. Its report, “Toxic Substances,” defined a need for 
comprehensive legislation to identify and control chemicals whose manufacture, processing, 
distribution, use, and/or disposal was potentially dangerous and not adequately regulated under 
other environmental statutes. The House and Senate each passed bills in both the 92nd and 93rd 
Congresses (in 1972 and 1973, respectively), but controversies over the scope of chemical 
screening prior to commercial production and distribution, level of costs, and the relationship to 
other regulatory laws stalled final action. Episodes of environmental contamination—including 
the Hudson River and other waterways by PCBs, the threat of stratospheric ozone depletion from 
chlorofluorocarbon (CFC) emissions, and contamination of agricultural produce by 
polybrominated biphenyls (PBBs) in the state of Michigan—together with more exact estimates 
of the costs of imposing toxic substances controls, opened the way for final passage of the 
legislation. President Ford signed the TSCA into law on October 11, 1976. 
Title I 
TSCA (Title I) directs EPA to 
•  require manufacturers and processors to conduct tests for existing chemicals if 
(1) their manufacture, distribution, processing, use, or disposal may present an 
unreasonable risk of injury to health or the environment; or they are to be 
produced in substantial quantities and the potential for environmental release or 
human exposure is substantial or significant; (2) existing data are insufficient to 
predict the effects of human exposure and environmental releases; and (3) testing 
is necessary to develop such data (Section 4); 
•  prevent future risks through pre-manufacture screening and regulatory tracking 
of new chemical products (Section 5); 
•  control unreasonable risks already known, or as they are discovered for existing 
chemicals (Section 6); and 
•  gather and disseminate information about chemical production, use, and possible 
adverse effects to human health and the environment (Section 8). 
Authorization for appropriations for these activities and a state grant program for control of toxic 
substances in the environment expired on September 30, 1983, although appropriations for these 
programs have continued. 
Testing of Chemicals 
Many chemicals, even some in widespread use, are not well characterized in terms of their 
potential health and environmental effects. One of the major goals of TSCA was to induce the 
development of test data by producers (i.e., manufacturers, importers, and processors) of 
chemicals in commerce. Section 4 of TSCA directs EPA to require the development of test data 
Congressional Research Service 
95 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
on existing chemicals when certain conditions prevail: (1) the manufacture, processing, 
distribution, use, or disposal of the chemical “may present an unreasonable risk,” or (2) the 
chemical is produced in very large volume and there is a potential for a substantial quantity to be 
released into the environment or for substantial or significant human exposure. Under either 
condition, EPA must issue a rule requiring tests if (a) existing data are insufficient to resolve the 
question of safety, and (b) testing is necessary to develop the data. 
Because there were more than 55,000 chemicals in U.S. commerce at the time EPA was to begin 
developing test rules, Congress established a special interagency committee to help EPA 
determine which chemicals should be considered first, and to coordinate testing needs and efforts 
among government agencies. At least every six months the Interagency Testing Committee (ITC) 
must consider candidate chemicals for inclusion on a list of substances that the ITC recommends 
to EPA for development and promulgation of test rules. TSCA directs the ITC to “designate” a 
subset of chemicals on the list for EPA action within 12 months. The list can contain no more than 
50 “designated” chemicals at any time. When a chemical is designated, EPA has one year to 
respond by issuing a proposed test rule or a notice explaining why no testing is needed. 
TSCA requires the ITC to consider the following factors when it makes listing decisions: (1) 
quantity of the substance to be manufactured, (2) quantity of the chemical in environmental 
releases, (3) number of people who will be exposed occupationally and the duration of exposure, 
(4) extent of non-occupational human exposure, (5) similarity of the chemical to any other 
chemical known to present an unreasonable risk, (6) existence of data concerning environmental 
or health effects of the chemical, (7) the quantity of information to be gained by testing, and (8) 
the availability of facilities and personnel for performing testing. Chemicals known or suspected 
to cause or contribute to cancer, gene mutations, or birth defects are to be assigned a higher 
priority. In response to information that indicates “there may be a reasonable basis to conclude 
that a chemical ... presents or will present a significant risk of serious or widespread harm to 
human beings from cancer, gene mutations, or birth defects,” TSCA requires EPA action to 
prevent or reduce that risk or publication of a finding that the risk is not unreasonable. 
Pre-manufacture Notification for New Chemicals or Uses 
TSCA (Section 5) requires manufacturers, importers, and processors to notify EPA at least 90 
days prior to producing or otherwise introducing a new chemical product into the United States. 
Any information or test data that is known to, reasonably ascertainable by, or in possession of the 
notifier, and that might be useful to EPA in evaluating the chemical’s potential adverse effects on 
human health or the environment, must be submitted to EPA at the same time. TSCA also requires 
EPA to be notified when there are plans to produce, process, or use an existing chemical in a way 
that differs from previously permitted uses, if the Administrator has determined by rule that new 
uses of the chemical may produce significant changes in human and environmental exposures and 
therefore require notification. The 90-day notice provides EPA with the opportunity to evaluate 
the chemical use and, if necessary, to prohibit or limit such activity before it occurs to prevent 
unreasonable risk of injury to human health or the environment. 
EPA has 45 days after notification (or up to 90 days if it extends the period for good cause) to 
evaluate the potential risk posed by the chemical. If EPA determines that there is a reasonable 
basis to conclude that the substance presents or will present an unreasonable risk, the 
Administrator must promulgate requirements to protect adequately against such risk. 
Alternatively, EPA may determine that the proposed activity related to a chemical does not 
present an unreasonable risk; this decision may be based on the available data, or, when no data 
Congressional Research Service 
96 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
exist to document the effects of exposure, on what is known about the effects of chemicals in 
commerce with similar chemical structures and used in similar ways. 
The purpose of EPA’s screening procedure is to identify potential hazards, and control them 
before use of a chemical becomes widespread. If data are inadequate to make an informed 
judgment and (1) manufacture, processing, distribution in commerce, use, or disposal may present 
an unreasonable risk, or (2) a chemical is to be produced in substantial quantities, and the 
potential for environmental release or human exposure is substantial or significant, EPA may 
issue a proposed order to prohibit or limit such activities until sufficient data are submitted. 
Although the legislative history of TSCA includes a presumption that testing of new products 
would take place before they were widely used, either as the chemical was developed, or as its 
markets grew, TSCA also forbids promulgation of blanket testing requirements for all new 
chemicals. This reflects concern that uniform testing requirements might stifle innovation in the 
chemical industry. Thus, EPA must decide which chemicals, or which categories of chemicals, 
warrant the costs of premarket testing. EPA reviews more than 1,000 new chemical 
manufacturing notices annually. 
Regulatory Controls for Hazardous Chemicals 
TSCA requires EPA to regulate manufacturing, processing, distribution in commerce, use, or 
disposal of a chemical if it will present an unreasonable risk of injury to health or the 
environment, and the risk cannot be reduced to a sufficient degree under another federal law 
administered by EPA. The alternative means available to EPA for controlling chemical hazards 
that present unreasonable risks are specified in Section 6 of TSCA. EPA has the authority to: 
•  prohibit or limit the amount of production or distribution of a substance in 
commerce; 
•  prohibit or limit the production or distribution of a substance for a particular use; 
•  limit the volume or concentration of the chemical produced; 
•  prohibit or regulate the manner or method of commercial use; 
•  require warning labels and/or instructions on containers or products; 
•  require notification of the risk of injury to distributors and, to the extent possible, 
consumers; 
•  require record-keeping by producers; 
•  specify disposal methods; and 
•  require replacement or repurchase of products already distributed. 
EPA also may impose any of these requirements in combination, or for a specific geographical 
region. However, EPA is required by TSCA to regulate only “to the extent necessary to protect 
adequately” against a risk, and to use the “least burdensome” regulatory approach, even in 
controlling unreasonable risks. 
Congressional Research Service 
97 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
Information Gathering 
Section 8 of TSCA requires EPA to develop and maintain an inventory of all chemicals, or 
categories of chemicals, manufactured or processed in the United States. The first version of this 
inventory identified approximately 55,000 chemicals in commerce in 1979. All chemicals not on 
the inventory are, by definition, “new” and subject to the notification provisions of Section 5. 
These chemicals must be added to the inventory if they enter U.S. commerce. Chemicals need not 
be listed if they are only produced in very small quantities for purposes of experimentation or 
research. 
Two chemical substances are directly addressed in Title I: PCBs and elemental mercury. TSCA 
directs EPA to regulate PCBs and to ban most uses. In addition, TSCA prohibits the sale, 
distribution, or transfer of elemental mercury by federal agencies. 
To aid EPA in its duties under TSCA, the agency was granted considerable authority to collect 
information from industries. EPA may require maintenance of records and reporting of: chemical 
identities, names, and molecular structures; categories of use; amounts manufactured and 
processed for each category of use; descriptions of byproducts resulting from manufacture, 
processing, use, and disposal; environmental and health effects; number of individuals exposed; 
number of employees exposed and the duration of exposure; and manner or method of chemical 
disposal. 
Manufacturers, processors, and distributors of chemicals are required to maintain records of 
significant adverse reactions to health or the environment alleged to have been caused by a 
substance or mixture. Records of adverse effects on the health of employees must be retained for 
30 years from the date of reporting. Industry also must submit lists and copies of health and safety 
studies. Studies showing adverse effects previously unknown must be submitted to EPA as soon 
as they are completed or discovered. 
Imminent Hazards 
Section 7 provides EPA authority to take emergency action through the district courts to control a 
chemical substance or mixture which presents an imminent and unreasonable risk of serious 
widespread injury to health or the environment. 
Relation to Other Laws 
Section 9 allows EPA to refer cases of chemical risk to other federal agencies with the authority to 
prevent or reduce the risk. For statutes under EPA’s jurisdiction, TSCA gives the Administrator 
discretion to decide if a risk can best be handled under the authority of TSCA. 
Enforcement and Judicial Review 
Section 11 authorizes EPA to inspect any facilities subject to TSCA requirements and to issue 
subpoenas requiring attendance and testimony of witnesses, production of reports and documents, 
answers to questions and other necessary information. Section 13 mandates TSCA enforcement at 
the national borders by the Treasury Department. 
Congressional Research Service 
98 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
Section 15 identifies acts prohibited under TSCA, while Section 16 describes penalties for acts 
violating these prohibitions, as well as recourse available to anyone accused of such violations. 
Section 16 authorizes civil penalties, not to exceed $25,000 per violation per day, and affords the 
defendant an opportunity to request a hearing before an order is issued and to petition for judicial 
review of an order after it is issued. Criminal penalties also are authorized for willful violations. 
Section 17 provides jurisdiction to U.S. district courts in civil actions to enforce TSCA Section 15 
by restraining or compelling actions that violate or comply with it, respectively. Chemicals may 
be seized and condemned if their manufacture, processing, or distribution violated the act. 
Section 19 authorizes any person to file a petition for judicial review of specified rules within 60 
days of issuance under TSCA. The court is directed to set aside specified rules if they are not 
supported by substantial evidence in the rulemaking record taken as a whole. 
Section 20 authorizes civil suits by any person against any person in violation of the act. It also 
authorizes suits against EPA to compel performance of nondiscretionary actions under TSCA. 
Section 21 provides the public with the right to petition for the issuance, amendment, or repeal of 
a rule requiring toxicity testing of a chemical, regulation of the chemical, or reporting. 
Confidential Business Information 
Section 14 provides broad protection of proprietary confidential information about chemicals in 
commerce. Disclosure by EPA employees of such information generally is not permitted, except 
to other federal employees, or when necessary to protect health or the environment. Data from 
health and safety studies of chemicals is not protected unless its disclosure would reveal a 
chemical process or chemical proportion in a mixture. Wrongful disclosure of confidential data by 
federal employees is prohibited, and may result in criminal penalties. 
Chemical Categories 
Section 26 allows EPA to impose regulatory controls on categories of chemicals, rather than on a 
case-by-case basis. However, EPA cannot regulate a group merely because it is composed of new 
chemical substances. 
State Preemption 
TSCA Section 18 preempts state actions that establish or continue in effect requirements 
applicable to a chemical substance or mixture that is federally regulated under TSCA Sections 5 
or 6, unless the state requirement is identical to the federal requirement, implements another 
federal law, or prohibits use of the substance or mixture within the state. However, a state may 
ask EPA to allow a state requirement that provides a significantly higher degree of protection 
from risk than does the federal requirement. 
Other Provisions 
TSCA Section 10 directs EPA to conduct and coordinate among federal agencies research, 
development, and monitoring that is necessary to the purposes of the act. 
Section 12 excludes chemical products manufactured for export from TSCA requirements except 
for reporting and record keeping requirements in Section 8. In 2008, Congress excluded 
Congressional Research Service 
99 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
elemental mercury from this exemption, banning its export beginning in 2013, with the exception 
of mercury contained in coal. Other exceptions from essential uses may be granted by rule. 
Section 22 waives compliance when in the interest of national defense. 
Section 23 provides protection of employees who assist in carrying out the provisions of the act 
(i.e., “whistle-blowers”). 
The potential effects of TSCA rules on employment must be monitored by EPA, according to 
Section 24. 
Section 25 mandates study of the need for indemnification of people affected by federal laws 
administered by EPA and of the feasibility of establishing a standard classification system for 
chemical substances and of storing and retrieving information about them. 
Section 26 authorizes data sharing and cooperative action to facilitate TSCA implementation 
between EPA and other federal agencies. It also authorizes collection of fees for EPA processing 
of data submitted in response to an order under Section 4 or 5. EPA is directed to establish an 
office to assist the regulated community. The agency also must establish a procedure to ensure 
disclosure of financial interests in the regulated community by EPA employees. Final orders 
issued under TSCA must contain a statement of basis and purpose. Finally, Section 26 established 
within EPA a new Assistant Administrator for Toxic Substances. 
TSCA Section 27 authorizes research and development of test methods for chemicals by the 
Public Health Service in cooperation with EPA. 
Grants to states are authorized by Section 28 to establish and operate programs to prevent or 
eliminate unreasonable risks to health or the environment. 
Section 29 authorized appropriations through 1983. 
An annual report is mandated by Section 30. 
Title II (Asbestos in Buildings) 
Growing public concern about the presence of potentially hazardous asbestos in buildings, 
especially in schools, led to congressional efforts to address this problem. Title II of TSCA, the 
Asbestos Hazard Emergency Response Act (AHERA), was enacted in 1986 (P.L. 99-519) and 
amended in July 1988 (P.L. 100-368). It required EPA to set standards by October 1987, for 
responding to the presence of asbestos in schools. The standards, set at levels adequate to protect 
public health and the environment, identify appropriate response actions that depend on the 
physical condition of asbestos. Schools, in turn, were required to inspect for asbestos-containing 
material, and to develop and implement a plan for managing any such material. Plans for 
managing asbestos were to be submitted by schools before May 1989, and implementation was to 
begin by July 1989. The law contains no deadlines for schools to complete implementation. 
Title II requires asbestos contractors and analytical laboratories to be certified, and schools to use 
certified persons for abatement work. Training and accreditation requirements also apply to 
inspectors, contractors, and workers performing asbestos abatement work in all public and 
commercial buildings. EPA may award training grants to nonprofit organizations for asbestos 
Congressional Research Service 
100 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
health and safety programs. However, authorization of appropriations for this grant program 
expired September 30, 1995. Other Title II requirements (such as mandates that buildings be 
inspected for asbestos) have not been extended to non-school buildings. 
To enforce requirements, TSCA authorizes EPA to take emergency action with respect to schools 
if school officials do not act to protect children. The act also authorizes citizen action with respect 
to asbestos-containing material in a school and to compel action by EPA, either through 
administrative petition or judicial action. Civil penalties not to exceed $5,000 are authorized for 
violations such as failing to conduct an inspection or to develop a school management plan. 
Concern about how schools would pay for required actions was addressed in separate legislation 
(the Asbestos School Hazard Abatement Act of 1984, or ASHAA, P.L. 98-377). It established a 
program offering grants and interest-free loans to schools with serious asbestos problems and 
demonstrated financial need. Although EPA for several years did not request funding for this 
program, Congress appropriated funds. Authorization of appropriations for this program expired 
September 30, 1995, and Congress has not appropriated funds since FY1993; a total of $382 
million in grant and loan funds were appropriated from FY1984 through FY1993. Repaid 
ASHAA loans are returned to an Asbestos Trust Fund, established in TSCA Title II, to become a 
dedicated source of revenues for future asbestos control projects. 
Title III (Radon Programs) 
In October 1988 Congress amended TSCA by adding Title III—Indoor Radon Abatement (15 
U.S.C. 2661 et seq., P.L. 100-551). The basic purpose of Title III is to provide financial and 
technical assistance to the states that choose to support radon monitoring and control; neither 
monitoring nor abatement of radon is required by the act. 
Title III required EPA to update its pamphlet “A Citizen’s Guide to Radon,” to develop model 
construction standards and techniques for controlling radon levels within new buildings, and to 
provide technical assistance to states. EPA is to provide technical assistance by: establishing an 
information clearinghouse; publishing public information materials; establishing a national 
database of radon levels detected, organized by state; providing information to professional 
organizations representing private firms involved in building design and construction; submitting 
to Congress a plan for providing financial and technical assistance to states; operating cooperative 
projects with states; conducting research to develop, test, and evaluate radon measurement 
methods and protocols; developing and demonstrating new methods of radon measurement and 
mitigation, including methods that are suitable for use in nonresidential child care facilities; 
operating a voluntary program to rate radon measurement and mitigation devices and methods 
and the effectiveness of private firms and individuals offering radon-related services; and 
designing and implementing training seminars. The proficiency rating program and certification 
for training programs collect fees for service, and therefore, are meant to be self-supporting, but 
Congress authorized $1,500,000 to be appropriated to establish these programs. Congress 
authorized $3,000,000 to be appropriated for each of three years beginning in 1989 for the other 
provisions of Sections 303, 304, and 305. 
A matching grant program was established for the purpose of assisting states in developing and 
implementing programs for radon assessment and mitigation. For this program, $30 million was 
authorized to be appropriated over three years, with funds targeted to states or projects that made 
efforts to ensure adoption of EPA’s model construction standards and techniques for new 
buildings; gave preference to low-income persons; or addressed serious and extensive radon

contamination problems or had the potential to reduce risk or to develop innovative assessment 
techniques, mitigation measures, or management approaches. 
Other sections of Title III require EPA to: conduct a study to determine the extent of radon 
contamination in schools; identify and list areas of the U.S. with a high probability of having high 
levels of indoor radon; make grants or cooperative agreements to establish and operate at least 
three regional radon training centers; and provide guidance to federal agencies on radon 
measurement, risk assessment, and remedial measures. 
All authorizations for appropriations specific to this title expired September 30, 1991, although 
appropriations have continued. 
Title IV (Lead Exposure Reduction) 
The 102nd Congress added Title IV to TSCA when it enacted the Residential Lead-Based Paint 
Hazard Reduction Act of 1992 as Title X in the Housing and Community Development Act of 
1992 (P.L. 102-550). Title IV aims to accelerate federal efforts to reduce risks to young children 
who daily are exposed to lead-based paint in their homes. In addition, it is expected to stimulate 
development of lead inspection and hazard abatement services in the private sector, while 
ensuring that the services provided and any products employed are reliable and effective in 
reducing risk. To these ends, Title IV directs EPA: 
•  to promulgate definitions of lead-contaminated dust, lead-contaminated soil, and 
lead-based paint hazards; 
•  to ensure that people engaged in detection and control of lead hazards are 
properly trained and that contractors are certified; 
•  to publish requirements for the accreditation of training programs for workers; 
•  to develop criteria to evaluate the effectiveness of commercial products used to 
detect or reduce risks associated with lead-based paint; 
•  to establish protocols, criteria, and minimum performance standards for 
laboratory analysis of lead in paint films, soil, and dust; 
•  to establish a program to certify laboratories as qualified to test substances for 
lead content; and 
•  to publish and distribute to the public a list of certified or accredited 
environmental sampling laboratories. 
Title IV explicitly applies these requirements to federal facilities and activities that may create a 
lead hazard. 
In addition, Congress directed EPA to conduct a study of lead hazards due to renovation and 
remodeling activities that may incidentally disturb lead-based paint. EPA is required to 
promulgate guidelines for the renovation and remodeling of buildings or other structures when 
these activities might create a hazard. 
Title IV directs EPA to establish a clearinghouse and hotline to distribute information about the 
hazards of lead-based paint, how to avoid exposure and reduce risk, and new technologies for 
removing or immobilizing lead-based paint. In addition, Congress mandated development of: a 
Congressional Research Service 
102 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
lead hazard information pamphlet; public education and outreach activities for health 
professionals, the general public, homeowners, landlords, tenants, consumers of home 
improvement products, the residential real estate industry, and the home renovation industry; and 
information to be distributed by retailers of home improvement products to provide consumers 
with practical information related to the hazards of renovation where lead-based paint may be 
present. 
Title IV authorizes states to propose programs to train and certify inspectors and contractors 
engaged in the detection or control of lead-based paint hazards. States also may develop the 
required informational pamphlets. TSCA requires EPA to promulgate a model state program that 
may be adopted by any state. Congress gave EPA the authority to approve or disapprove 
authorization for state proposals and to provide grants for states to develop and implement 
authorized programs. A federal program must be established, administered, and enforced by EPA 
in each state without an authorized program. 
The Department of Health and Human Services also has responsibilities under Title IV of TSCA. 
It mandates a study by the Centers for Disease Prevention and Control (CDC) and the National 
Institute for Environmental Health Sciences to determine the sources of lead exposure to children 
who have elevated lead levels in their bodies. The National Institute for Occupational Safety and 
Health is directed to study ways of reducing occupational exposure to lead during abatement 
activities. 
The act established a rule-making docket to ensure the availability to the general public of all 
documents submitted to agencies that are relevant to regulatory decisions pursuant to this 
legislation. The docket is required to include the drafts of all proposed rules submitted by EPA to 
the President’s Office of Management and Budget (OMB), written comments on the drafts, and 
written responses to comments. In addition, the agency must provide an explanation for any 
major change to a proposed rule that appears in the final rule, and such changes may not be made 
based on information not filed in the docket. Dockets are required to be established in each EPA 
regional office. 
Congress authorized to be appropriated “such sums as may be necessary” for TSCA Title IV. 
In addition to amending TSCA, Title X of the Housing and Community Development Act of 1992 
authorized grants to states for risk assessments and lead-based paint removal and immobilization 
in private housing for low-income residents; establishing state training, certification, or 
accreditation programs for inspectors and abatement contractors; and research at the Department 
of Housing and Urban Development (HUD). Authorization for appropriations for these grants 
expired September 30, 1994, but appropriations have continued. Title X directed HUD to 
establish guidelines for federally supported work involving risk assessments, inspections, interim 
controls, and abatement of lead-based paint hazards. In addition, the National Institute for 
Occupational Safety and Health (NIOSH) was provided $10 million for training people who 
remove or immobilize paint. 
Title V (Reducing Risks in Schools) 
At the end of 2007, the 110th Congress added a fifth title to TSCA, subtitled Healthy High-
Performance Schools. Enacted as Title IV, Subtitle E (Section 461) of P.L. 110-140, the Energy 
Independence and Security Act of 2007, TSCA Title V authorizes EPA to establish a state grant 
program to provide technical assistance for EPA programs to schools and develop and implement 
Congressional Research Service 
103 
Environmental Laws: Summaries of Major Statutes Administered by EPA 
 
state school environmental health programs. State programs must include standards for school 
building design, construction, and renovation, and identify ongoing school building 
environmental problems and recommended solutions. Environmental problems specifically 
mentioned in the law include “contaminants, hazardous substances, and pollutant emissions.” 
EPA’s authority to provide grants expires five years after the date of enactment. 
Title V requires the EPA Administrator, in consultation with the Secretary of Education and the 
Secretary of Health and Human Services, to issue voluntary guidelines within 18 months of Title 
V enactment for selecting sites for schools (presumably new schools). The guidelines are to 
account for the “special vulnerability of children to hazardous substances or pollution exposures 
in any case in which the potential for contamination at a potential school site exists,” modes of 
transportation available to students and staff, efficient use of energy, and potential use of a school 
at the site as an emergency shelter. 
Title V also requires the EPA Administrator, in consultation with the Secretary of Education and 
the Secretary of Health and Human Services, to issue voluntary guidelines within two years of 
enactment for developing and implementing state environmental health programs for schools. 
These guidelines must take into account the findings of federal initiatives established under 
“relevant federal law with respect to school facilities,” including initiatives related to water and 
energy conservation authorized by Sections 431 through 441, and work related to high-
performance green buildings authorized by Section 492 of P.L. 110-140. In particular, the 
guidelines must take into account “environmental problems, contaminants, hazardous substances, 
and pollutant emissions”; natural day lighting; ventilation; heating and cooling; moisture control 
and mold; maintenance, cleaning, and pest control; acoustics; and “other issues relating to the 
health, comfort, productivity, and performance of occupants of the school facilities.” In addition, 
Title V requires that the guidelines provide “technical assistance on siting, design, management, 
and operation of school facilities”; collaborate with children’s environmental health centers in 
school environmental investigations”; assist states and the public to better understand and 
improve the environmental health of children; and take into account “the special vulnerability of 
children in low-income and minority communities to exposures from contaminants, hazardous 
substances, and pollutant emissions.” 
Several provisions in Title V refer to entities established under other sections of the Energy 
Independence and Security Act of 2007 (P.L. 110-140). For example, Title V contains directives 
for the Federal Director of the Office of Federal High-Performance Green Buildings in the 
General Services Administration, which was created by Section 436(a). In addition, there is 
reference to the national high-performance green building clearinghouse established in Section 
423(1) “to carry out public outreach to inform individuals and entities of the information and 
services [related to high-performance green buildings] available governmentwide.” Title V 
requires the Federal Director to ensure, “to the maximum extent practicable,” that the public 
clearinghouse “receives and makes available information on the exposure of children to 
environmental hazards in school facilities.” The EPA Administrator is directed to prepare an 
annual report to Congress on activities carried out under Title V authority, and this report also 
must be made available to the public through the clearinghouse. 
For the purposes of carrying out the provisions of Title V, Congress authorized appropriations of 
$7 million through FY2013.

Title VI (Limiting Formaldehyde Emissions) 
In July 2010, Congress enacted the Formaldehyde Standards for Composite Wood Products Act 
(P.L. 111-199), adding a new Title VI to TSCA. The new title mandates specific formaldehyde 
emission standards for hardwood plywood, medium-density fiberboard, and particleboard that is 
sold, supplied, offered for sale, or manufactured in the United States. The standards are phased in 
over 2 years from enactment and are based on the voluntary national formaldehyde emissions 
standards established by ASTM International (formerly known as the American Society for 
Testing and Materials), method ASTM E-1333-96 (2002).  
The standards apply to plywood, particleboard, and medium-density fiberboard in the form of an 
unfinished panel or incorporated into a finished good. Certain products are excluded, including 
many forms of lumber and panels used for outdoor applications, such as structural plywood, 
prefabricated wood I-joists, most windows, antiques or other previously owned goods, and 
composite wood products used inside automobiles, trucks, rail cars, boats, and aircraft. 
EPA is required to promulgate regulations ensuring compliance with the emission standards and 
must include provisions relating to labeling, chain of custody requirements, sell-through 
provisions; ultra low-emitting formaldehyde resins, finished goods, third-party testing and 
certification; auditing and reporting of third-party certifiers; recordkeeping; enforcement, 
laminated products; and exceptions for products and components containing “de minimis 
amounts” of composite wood products. The new law prohibits stockpiling of products 
manufactured before the effective date of the act for sale after that date. Also prohibited is any 
requirement for labeling products manufactured prior to the “designated date of manufacture.” 
P.L. 111-199 requires an annual report to Congress on the status of implementation and the extent 
to which relevant industries have achieved compliance. Finally, the act directs the Secretary of 
Housing and Urban Development to update regulations concerning formaldehyde emissions from 
composite wood in manufactured homes (24 Code of Federal Regulations 3280.308) to ensure 
that the standards established by TSCA Title VI are implemented.

Pesticide Laws66 
The Environmental Protection Agency (EPA) is responsible for implementing federal pesticide 
policies under two statutes: the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA),67 
governing the sale and use of pesticide products within the United States; and the Federal Food, 
Drug, and Cosmetic Act (FFDCA), which limits pesticide residues on food in interstate 
commerce (including imports). Pesticides are broadly defined in FIFRA Section 2(u) as chemicals 
and other products used to kill, repel, or control pests. Familiar examples include pesticides used 
to kill insects and weeds that can reduce the yield, and sometimes harm the quality, of agricultural 
crops, ornamental plants, forests, wooden structures, and also pastures. But the broad definition of 
“pesticide” in FIFRA also applies to products with less familiar “pesticidal uses.” For example, 
substances used to control mold, mildew, algae, and other nuisance growths on equipment, in 
surface water, or on stored grains are pesticides. The term also applies to disinfectants and 
sterilizing agents, animal repellents, rat poison, and many other substances. EPA estimates that 
there are about 18,000 pesticide products currently in use.68 These all are regulated under FIFRA, 
but approximately 5,800 pesticide products used in food production also are regulated under the 
FFDCA, as discussed below. 
FIFRA directs EPA to restrict the use of pesticides as necessary to prevent unreasonable adverse 
effects on people and the environment, taking into account the costs and benefits of various 
pesticide uses. FIFRA requires EPA to regulate the sale and use of pesticides in the United States 
through registration and labeling.69 The act prohibits sale of any pesticide in the United States 
unless it is registered and labeled to indicate approved uses and restrictions. It is a violation of the 
law to use a pesticide in a manner that is inconsistent with the label instructions. EPA registers 
each pesticide product for each approved use. For example, a product may be registered for use 
on green beans to control mites, as a seed treatment for cotton, and as a treatment for structural 
cracks. In addition, FIFRA requires EPA to reregister older pesticides based on new data that meet 
current regulatory and scientific standards. Establishments that manufacture or sell pesticide 
products must register with EPA. Facility managers are required to keep certain records and to 
allow inspections by federal or state regulatory officials. 
For the approximately 600 or more pesticides (i.e., active ingredients) registered for use in food 
production, the FFDCA Section 408 authorizes EPA to establish maximum allowable residue 
                                                                  
66 Prepared by Linda-Jo Schierow, Specialist in Environmental Policy, Environmental Policy Section, Resources, 
Science, and Industry Division.

levels (called tolerances) that ensure that human exposure to the pesticide ingredients in food and 
animal feed will be “safe”.70 A “safe” tolerance is defined as a level at which there is “a 
reasonable certainty of no harm” from the exposure. Under FFDCA, foods with a residue of a 
pesticide ingredient for which there is no tolerance established, or with a residue level exceeding 
an established tolerance limit, are declared “unsafe” and “adulterated”; such foods cannot be sold 
in interstate commerce or imported to the United States. Pesticides may not be registered under 
FIFRA for use on food unless tolerances (or exemptions) have been established under the 
FFDCA. 
History of Federal Pesticide Law 
Table 18 and Table 19 list the original enactment of FIFRA and FFDCA and major amendments 
to these statutes, respectively. 
FIFRA 
Federal pesticide legislation was first enacted in 1910. It aimed to reduce economic exploitation 
of farmers by manufacturers and distributors of adulterated or ineffective pesticides. Congress did 
not address the potential risks to human health posed by pesticide products until it enacted FIFRA 
in 1947. The U.S. Department of Agriculture (USDA) was responsible for administering the 
pesticide statutes during this period. However, responsibility was shifted to the EPA when that 
agency was created in 1970. Broader congressional concerns about long- and short-term toxic 
effects of pesticide exposure on people who applied pesticides (applicators), wildlife, nontarget 
insects and birds, and on consumers, subsequently led to a complete revision of FIFRA in 1972. 
The 1972 law completely replaced the original 1947 law, and is the basis of current federal policy. 
Substantial changes were made in 1988 (P.L. 100-532), 1996 (P.L. 104-170), and 2004 (P.L. 108-
199). The 1988 amendments focused on accelerating the reregistration process. The 1996 
amendments facilitated registration of pesticides for special (so-called “minor”) uses, 
reauthorized collection of fees to support reregistration, and required coordination of regulations 
implementing FIFRA and the FFDCA. The 2004 amendments, known as the Pesticide 
Registration Improvement Act (PRIA), modified the types and amounts of fees that EPA could 
collect to support its activities. The Pesticide Registration Improvement Renewal Act, or PRIA2 
(P.L. 110-94), enacted October 9, 2007, reauthorized and revised these fee provisions, which 
would have expired at the end of FY2008. 
Authorization for appropriations for FIFRA expired on September 31, 1991, although 
appropriations bills have continued to provide funding to implement the law. Authority provided 
by FIFRA to EPA to issue and enforce regulations, is, for the most part, permanent, and is not 
affected by the expiration of the authorization of appropriations. 
                                                                  
70 Ingredients in pesticide products are categorized as active or inert. Active ingredients are those that are intended to 
control the pest, while inert ingredients are used to deliver the active ingredients effectively to the pest. Inert 
ingredients often are solvents or surfactants and often comprise the bulk of the pesticide product. Some inerts are 
known to be toxic, and some are known to be harmless, but EPA lists most in the category “inerts of unknown 
toxicity.”

FFDCA 
The original Federal Food, Drug, and Cosmetic Act of 1938 (FFDCA) established the structure of 
the current law. With respect to food safety, it required the Food and Drug Administration (then a 
part of the U.S. Department of Agriculture) to set maximum residue levels (tolerances) for 
unavoidable poisonous substances in food. Congress acted to protect consumers from pesticide 
residues on food in 1954 by adding a new Section 408 to the FFDCA. It directed FDA to set 
residue tolerances for all pesticides in raw agricultural commodities. Congress expanded the 
requirement for tolerances in the Food Additives Amendment of 1958, which added Section 409, 
directing FDA to set tolerances for food additives, including pesticide residues in processed 
foods. Section 409 also forbade the addition to food of any additive (including pesticide residue), 
if it was found to be a potential cancer-causing agent. This provision is referred to as the Delaney 
Clause.

In 1970, authority to establish tolerances for pesticide residues was transferred to the newly 
formed EPA. FDA (now in the Department of Health and Human Services) retained responsibility 
for enforcement of tolerances in food that is imported or sold across state boundaries. 
In 1996, Congress substantially revised requirements for pesticide residue tolerance setting in the 
Food Quality Protection Act (FQPA). The FQPA redefined terms so that pesticide residues in 
processed foods were no longer regulated as food additives, and therefore no longer were subject 
to the Delaney Clause. The FQPA also established a new safety standard of a “reasonable 
certainty of no harm” from exposure to pesticides. See Table 21 for a listing of current pesticides-
related provisions in the FFDCA. 
The Act of July 22, 1954, authorized such sums as may be necessary to carry out this FFDCA 
section (21 U.S.C. 346b). 
Registration of Pesticide Products 
When pesticide manufacturers apply to register a pesticide active ingredient, pesticide product, or 
a new use of a registered pesticide under FIFRA Section 3, EPA requires them to submit scientific 
data on toxicity and behavior in the environment. EPA may require data from any combination of 
more than 100 different tests, depending on the potential toxicity of active and inert ingredients 
and degree of exposure. To register a pesticide use on food, EPA also requires applicants to 
identify analytical methods that can be used to test food for residues of active ingredients, certain 
inert ingredients, and their breakdown products and to determine the amount of residue that could 
remain on crops, as well as on (or in) food products, assuming that the pesticide product is 
applied according to the manufacturers’ recommended rates and methods. 
Based on the data submitted, EPA determines whether and under what conditions the proposed 
pesticide use would present an unreasonable risk to human health or the environment. If the 
pesticide is proposed for use on a food crop, EPA also determines whether a “safe” level of 
pesticide residue, called a “tolerance,” can be established under the Federal Food, Drug, and 
Cosmetic Act. A tolerance must be established before a pesticide registration may be granted for 
use on food crops. If registration is granted, the agency specifies the approved uses and 
conditions of use, including safe methods of pesticide storage and disposal, which the registrant 
must explain on the product label. FIFRA requires that federal regulations for pesticide labels pre-
empt state, local, and tribal regulations. Use of a pesticide product in a manner inconsistent with 
its label is prohibited. 
EPA may classify and register a pesticide product for general or for restricted use. Products 
known as “restricted-use pesticides” are those judged to be more dangerous to the applicator or to 
the environment. Such pesticides can be applied only by people who have been trained and 
certified. Individual states and Indian tribes generally are responsible for training and certifying 
pesticide applicators. 
FIFRA Section 3 also allows “conditional,” temporary registrations if (1) the proposed pesticide 
ingredients and uses are substantially similar to currently registered products and will not create 
additional significant environmental risks; (2) an amendment is proposed for additional uses of a 
registered pesticide, and sufficient data are submitted indicating that there is no significant 
additional risk; or (3) data requirements for a new active ingredient require more time to generate 
than normally allowed, and use of the pesticide during the period will not cause any unreasonable 
adverse effect on the environment and will be in the public interest.

Tolerance Setting 
Any person who has registered a pesticide may petition EPA proposing establishment of a 
tolerance or an exemption for that pesticide to permit its use on food-related crops.71 Tolerance 
petitions must include information about pesticide application rates, measured concentrations of 
pesticide residues on the food after the pesticide has been applied according to directions on its 
label, and safety of pesticide use on food crops. The FFDCA requires EPA to respond to each 
petition by establishing a tolerance or exempting the pesticide from the requirement. If the 
pesticide will not leave residues above an established safe level, EPA will register the pesticide 
for use on that food product and set the tolerance level by issuing a regulation. EPA tolerances for 
pesticide residues preempt state and local restrictions on food, if the state and local restrictions 
are based on lower residue levels. States may petition for an exception if the EPA-set residue 
level threatens public health. 
The FFDCA, Section 408, as amended, requires EPA to assess safety in terms of total exposure to 
the pesticide (that is, to the concentration of pesticide allowed by the tolerance, together with all 
other dietary and non-food exposures for which there is reliable information) as well as to other 
pesticides that have the same toxic effects on people. No quantitative standard of safety is 
established by law, but the House Committee on Commerce (now the Committee on Energy and 
Commerce) noted in its report on the bill that became the FQPA that EPA should continue setting 
standards to ensure safety as it had in the past: 
... the Committee expects that a tolerance will provide a ‘reasonable certainty of no harm’ if 
the Administrator determines that the aggregate exposure to the pesticide chemical residue 
will be lower by an ample margin of safety than the level at which the pesticide chemical 
residue will not cause or contribute to any known or anticipated harm to human health. The 
Committee further expects, based on discussions with the Environmental Protection Agency, 
that the Administrator will interpret an ample margin of safety to be a 100-fold safety factor 
applied to the scientifically determined ‘no observable effect’ level when data are 
extrapolated from animal studies.72 
In determining a safe level, the FFDCA directs EPA to take into account many factors, including 
available information on dietary exposure to pesticides among infants and children. FQPA strictly 
limited the nature and influence of benefits considered in tolerance setting under Section 408 of 
the FFDCA. As amended, Section 408 allows EPA to maintain or modify existing tolerances (but 
not to establish new tolerances) at higher than “safe” residue levels only if the pesticide use 
avoids other greater risks to consumers, or is necessary to avoid significant disruption in domestic 
production of an adequate, wholesome, and economical food supply. Such higher tolerance levels 
may be set only for pesticides that are potential carcinogens (or have some other health effect) for 
which there is no known level of exposure at which no harm is anticipated (known as a non-
threshold effect). 
The higher tolerance level allowed for such pesticide residues must be “safe” for infants and 
children, as well as with respect to health effects for which there is a known threshold (that is, a 
level below which exposure is known to be harmless). The higher cancer (or other non-threshold) 
                                                                  
71 That is, use on food crops, animal feed crops, or food products directly (e.g., grains, fruits, or vegetables after 
harvest).

Congress, 2nd sess., 1996, p. 6.

risk posed by the tolerance on an annual basis may not be more than 10 times the risk at a “safe” 
level of exposure and not more than twice the risk of a “safe” level over a lifetime. 
For non-threshold effects, the House Commerce Committee provided additional guidance for 
establishing a level of residue that should be considered “safe.” 
In the case of a nonthreshold effect which can be assessed through quantitative risk 
assessment, such as a cancer effect, the Committee expects, based on its understanding of 
current EPA practice, that a tolerance will be considered to provide a ‘reasonable certainty of 
no harm’ if any increase in lifetime risk, based on quantitative risk assessment using 
conservative assumptions, will be no greater than ‘negligible.’ It is the Committee’s 
understanding that, under current EPA practice, ... EPA interprets a negligible risk to be a 
one-in-a-million lifetime risk. The Committee expects the Administrator to continue to 
follow this interpretation.73 
The “safe” standard applies to both raw and processed foods, and requires EPA to consider 
cumulative and aggregate exposure to pesticides in food, drinking water, air, and consumer 
products. Congress directed EPA to reevaluate all existing tolerances against this standard before 
August 2006. 
FFDCA directs the FDA in the Department of Health and Human Services and USDA to monitor 
pesticide residue levels in food in interstate commerce and to enforce tolerances through their 
food inspection programs. USDA is responsible for inspecting meat and poultry; FDA inspects all 
other foods. States also may monitor pesticide residues in food sold within their jurisdictions. 
FIFRA-FFDCA Coordination 
EPA has long coordinated pesticide registrations for food uses under FIFRA with tolerance setting 
under the FFDCA. The Food Quality Protection Act of 1996 (FQPA; P.L. 104-170) codified this 
policy. Thus, if EPA revokes a residue tolerance under FFDCA, it cancels the FIFRA pesticide 
registration for that food use. Similarly, if a pesticide registration for use on a food crop is 
canceled, EPA also cancels the residue tolerance for food. However, just as FIFRA allows 
continued use of remaining pesticide stocks after a registration is canceled, FFDCA allows 
continued commerce in commodities legally treated with a pesticide. Thus, EPA does not 
immediately revoke the tolerance for the pesticide residue when it cancels the corresponding 
registration. 
Public Disclosure, Exclusive Use, and Trade Secrets 
FIFRA Section 3 directs EPA to make the data submitted by the applicant for pesticide 
registration publicly available within 30 days after a registration is granted. However, applicants 
may claim certain data are protected as trade secrets under FIFRA, Section 10. If EPA agrees that 
the data are protected, the agency must withhold those data from the public, unless the data 
pertain to the health effects or environmental fate or effects of the pesticide ingredients. 
Information may be protected if it qualifies as a trade secret and reveals (1) manufacturing 
processes; (2) details of methods for testing, detecting, or measuring amounts of inert ingredients; 
or (3) the identity or percentage quantity of inert ingredients.

Companies sometimes seek to register a product based upon the registration of similar products, 
relying upon the data provided by the original registrant that are publicly released. This is 
allowed. However, Section 3 of FIFRA provides for a 10-year period of “exclusive use” by the 
registrant of data submitted in support of an original registration or a new use. In addition, an 
applicant who submits any new data in support of a registration is entitled to compensation for the 
cost of data development by any subsequent applicant who supports an application with that data 
within 15 years of its submission. If compensation is not jointly agreed upon by the registrant and 
applicant, binding arbitration can be invoked. 
Reregistration 
Most pesticides currently registered in the United States are older pesticides and were not subject 
to modern safety reviews when first registered. Amendments to FIFRA in 1972 directed EPA to 
“reregister” approximately 35,000 older products, in order to assess their safety in light of current 
standards. The task of reregistering older pesticides has been streamlined by reviewing groupings 
of products having the same active ingredients, on a generic instead of individual product basis. 
For food-use pesticides, EPA evaluated a pesticide’s eligibility for reregistration at the same time 
the agency reassessed the tolerance for that pesticide under the FFDCA. The FQPA required EPA 
to reassess pesticides posing the greatest risks first. Many of the 35,000 pesticide products were 
not reviewed and their registrations were canceled, because registrants did not request 
reregistration. At least 14,000 products are no longer in use. Nevertheless, the task for registrants 
and EPA was immense and costly. 
To accelerate the process of reregistration, Congress, in 1988 amendments to FIFRA, imposed a 
10-year reregistration schedule. To help pay for the additional costs of the accelerated process, 
Congress directed EPA to require registrants to pay reregistration and annual registration 
maintenance fees on pesticide ingredients and products. The 1996 amendments to FIFRA 
extended EPA’s authority to collect maintenance fees through FY2001. Exemptions from, or 
reductions in, fees were allowed for minor-use pesticides, public health pesticides, and small 
business registrants. Congress extended authority for fees annually through appropriations 
legislation after FY2001, until the omnibus appropriations legislation signed January 23, 2004 
(P.L. 108-199), modified the types and amounts of fees that EPA could collect, potentially 
through FY2008. 
The 2004 FIFRA amendments (PRIA) reauthorized collection of annual “maintenance” fees to 
support registration, designated a portion of those fees for the review of inert ingredients, and 
extended the deadline for completion of reregistration. PRIA directed EPA to complete 
Reregistration Eligibility Decisions (REDs) for pesticides with food uses/tolerances by August 3, 
2006, and to complete REDs for all remaining non-food use pesticides by October 3, 2008. The 
reregistration process will continue for several years after that date, as explained on the EPA 
reregistration website: 
After EPA has issued a RED and declared a pesticide eligible for reregistration, individual 
end-use products that contain the pesticide active ingredient still must be reregistered. 
Through this concluding part of the process, known as “product reregistration,” the Agency 
makes sure that the risk reduction measures called for in REDs are reflected on individual 
pesticide product labels. In some cases, the Agency uses Memoranda of Agreement or other 
measures to include risk reduction measures on pesticide labels sooner, before product 
Congressional Research Service

reregistration is completed. EPA plans to complete the last product reregistration decisions 
several years after the last REDs are signed.74 
EPA authority for administering these fees would have expired at the end of FY2008, but it was 
extended by the Pesticide Registration Improvement Renewal Act, or PRIA2 (P.L. 110-94), 
enacted October 9, 2007, effective retroactively to the beginning of FY2008 through FY2012. 
PRIA2 also made some technical revisions, primarily modifications to the fee payment process 
and an expansion of the range of categories of pesticide registration (licensing) activities subject 
to fees. 
Special Review 
EPA continues to evaluate the safety of pesticides after they are registered as new information 
becomes available. FIFRA requires registrants to report promptly any new evidence of adverse 
effects from pesticide exposure. If evidence indicates that a registered pesticide may pose an 
unreasonable risk, EPA may initiate a special review of available information to reevaluate the 
risks and benefits of each registered use. FIFRA also authorizes EPA to require registrants to 
conduct new studies to fill gaps in scientific understanding to assist risk assessments. As a result 
of a special review EPA may conclude that registration is adequate, needs amendment, or should 
be canceled. 
Canceling or Suspending a Registration 
If a special review or reregistration evaluation finds that a registered use may cause 
“unreasonable adverse effects,” EPA may amend or cancel the registration.75 FIFRA also allows 
registrants to request cancellation or amendment of a registration to terminate selected pesticide 
uses. Requesting voluntary cancellation sometimes reflects a registrant’s conclusion that the cost 
of additional studies is not worth the expected benefit (that is, profit) from sales if the registration 
would be maintained. 
If a registration is canceled for one or more uses of a pesticide, FIFRA does not permit it to be 
sold or distributed for those uses in the United States, although for a specified period of time, 
U.S. farmers may use remaining stocks, and commerce may continue for commodities that were 
legally treated with the pesticide. FIFRA allows registrants to appeal an EPA decision to cancel a 
registration. An appeal initiates a lengthy review process during which the product may continue 
to be marketed. However, if there is threat of an “imminent hazard” during the time required to 
cancel a registration, FIFRA authorizes EPA to suspend registration. Suspension orders, which 
also may be appealed, stop sales and use of the pesticide. In the event of suspension and 
cancellation, FIFRA Section 15 directs EPA to request an appropriation from Congress to 
compensate anyone who owned any of the pesticide and suffered any loss due to the suspension 
or cancellation. The registrant of the suspended and canceled product is responsible, however, for 
all of the transportation and disposal costs, and most storage costs. 
                                                                  
74 EPA. Pesticide Reregistration Facts. August 12, 2008. See 
http://www.epa.gov/oppsrrd1/reregistration/reregistration_facts.htm. 
75 Registrations also may be canceled under other conditions, for example, if data are not submitted in response to 
EPA’s request for additional information to maintain a registration, or if a registrant fails to pay the maintenance fee.

Use of Unregistered Pesticides 
FIFRA also allows for unregistered use of pesticide products in special circumstances. Section 5 
allows experimental use permits for purposes of research and to collect data needed to register a 
pesticide. Section 18 allows “emergency exemptions” from the provisions of FIFRA to be granted 
to federal or state agencies, for example, if there is a virulent outbreak of a disease that cannot be 
controlled by registered products. In addition, Section 24(c) permits states to allow additional 
uses of a federally registered product to meet “special local needs.” 
Enforcement 
Generally, EPA has the authority to enforce FIFRA requirements. However, FIFRA Section 26 
gives primary enforcement authority for pesticide use under FIFRA to states that have adequate 
enforcement procedures, laws, and regulations, including inspection authority. EPA is authorized 
by Section 27 to rescind a state’s primary enforcement responsibility if it is not being carried out. 
FIFRA Section 11 authorizes EPA to form cooperative agreements with states, giving them the 
responsibility for training and certifying applicators of restricted use pesticides. States also may 
initially review and give preliminary approval to applications for emergency exemptions and 
special local needs registrations, (although under some conditions FIFRA allows EPA later to 
deny state-approved applications). 
Section 9 authorizes inspections by EPA and authorized state officials of pesticide products where 
they are stored for distribution or sale. Section 13 authorizes EPA to issue orders to stop sales and 
to seize supplies of pesticide products. Civil and criminal penalties for violations of FIFRA are 
established in Section 14, while Section 15 provides indemnity payments for end users, 
distributors, and dealers of pesticides when registrations are suspended and canceled. 
Federal district courts are authorized in Section 16 to review EPA final actions and omissions 
when action is not discretionary. People adversely affected by an EPA order may file for judicial 
review of the order following a hearing. But, FIFRA does not authorize citizen suits against 
violators. 
Export of Unregistered Pesticides 
FIFRA does not give EPA the authority to regulate domestic production for export of unregistered 
pesticides, even if U.S. registration has been canceled for health or environmental reasons. 
However, FIFRA does require exporters to prepare or pack pesticides as specified by the 
purchaser and in accord with some of the FIFRA labeling provisions. For example, exporters 
must translate warning information into the language of the destination. FIFRA also requires 
exporters of unregistered pesticides to obtain the purchaser’s signature on a statement 
acknowledging that the pesticide is unregistered and cannot be sold in the United States. EPA is 
required to notify governments of other countries and international agencies whenever a 
registration, cancellation, or suspension of any pesticide becomes or ceases to be effective in the 
United States.

National Environmental Policy Act76 
The National Environmental Policy Act (NEPA, 42 U.S.C. 4321 et seq.) was enacted in 1969 and 
signed into law by President Nixon on January 1, 1970 (P.L. 91-190). NEPA was the first of 
several major environmental laws enacted in the 1970s. Under Title I of the act, Congress 
declared a national policy that stated, in part, that it is “the continuing policy of the Federal 
government ... to use all practicable means and measures ... to create and maintain conditions 
under which man and nature can exist in productive harmony, and fulfill the social, economic, 
and other requirements of present and future generations of Americans.” NEPA also created the 
Council on Environmental Quality (CEQ) in the Executive Office of the President. Among other 
duties, CEQ was required to develop and recommend to the President national policies to foster 
and promote the improvement of environmental quality. In the 1970’s, CEQ played a key role in 
shaping regulations for implementation of NEPA. 
One of the best-known elements of NEPA is its directive to federal agencies to incorporate 
environmental considerations in their planning and decision-making through a systematic 
interdisciplinary approach. Specifically, NEPA requires all federal agencies to prepare a detailed 
statement of the environmental impact of and alternatives to major federal actions significantly 
affecting the environment. The “detailed statement” was subsequently referred to as an 
environmental impact statement (EIS).77 
Judicial interpretation of NEPA ultimately determined that the act did not require agencies to 
elevate environmental concerns over other considerations. Rather, the courts determined, NEPA 
requires only that the agency take a “hard look” at a project’s environmental consequences before 
taking action. If the adverse environmental effects of the proposed action are adequately 
identified and evaluated, the agency is not constrained by NEPA from deciding that other benefits 
outweigh the environmental costs. 
In 1978, CEQ formally promulgated regulations, binding on all federal agencies, implementing 
NEPA’s provisions. In addition to CEQ, Congress authorized EPA to perform certain duties to 
ensure the proper implementation of NEPA’s EIS requirements (discussed below).

The NEPA Process 
NEPA applies to all major federal actions, including projects and programs entirely or partly 
funded, assisted, conducted, regulated, or approved by federal agencies. To ensure that 
environmental impacts of those actions are considered before final decisions are made, NEPA 
requires the preparation of an environmental impact statement (EIS) for any major federal action 
significantly affecting the quality of the human environment. An EIS is a full disclosure 
document that provides a description of the proposed action, and the existing environment, as 
well as analysis of the anticipated beneficial and adverse environmental effects of all reasonable 
alternatives.78 
As required under CEQ’s regulations, some level of analysis is also required when environmental 
impacts are uncertain or not significant. Projects for which it is not initially clear whether impacts 
will be significant require the preparation of an environmental assessment (EA). An EA is a 
concise public document that analyzes the environmental impacts of a proposed federal action 
and provides sufficient evidence to determine the level of significance of the impacts.79 It is 
followed by either a Finding of No Significant Impact (FONSI) or a decision to prepare an EIS. 
Categorical exclusions are actions that do not individually or cumulatively have a significant 
social, economic, or environmental effect, and which the applicable agency has determined from 
past experience have no significant impact. Such actions are excluded from the requirement to 
prepare an EIS or EA. 
Prior to completing the appropriate NEPA documentation, the responsible federal official (the 
“lead agency”) is required to consult with and obtain the comments of any federal agency which 
has jurisdiction by law or special expertise (a “cooperating agency”) with respect to any 
environmental impact involved. For any given federal action, compliance with a wide variety of 
legislative and regulatory requirements, enforceable by multiple agencies, may be required. 
NEPA documentation may be required to document compliance with all applicable environmental 
laws, executive orders, and other related requirements. Most agencies use the NEPA process as a 
means of coordinating or demonstrating compliance with all applicable environmental 
requirements. In this capacity NEPA may function as an “umbrella statute,” meaning any study, 
review, or consultation required by law, that is related to the environment, may be conducted 
within the framework of the NEPA process. 
Complex federal projects such as highway construction projects, forest thinning, or oil and gas 
development projects, may trigger compliance with literally dozens of federal, state, tribal, and 
local environmental statutory and regulatory requirements. These, in turn, require the 
participation or input of possibly dozens of agencies. Some Members of Congress have expressed 
concerns that the interagency coordination required of such projects is often inefficient, leading to 
unnecessary delays in needed projects. Improved interagency cooperation has been identified by 
some Members of Congress as a critical element to the success of streamlining the NEPA 
process.80 The CEQ’s regulations implementing NEPA currently include a variety of provisions 
intended to expedite the compliance process. In particular, CEQ’s regulations specify procedures

to reduce paperwork and delay. The regulations also direct agencies to efficiently facilitate the 
process of complying with multiple statutory and regulatory requirements. To do so, the 
regulations direct agencies, among other requirements to: 
•  Integrate NEPA’s requirements with other required planning and environmental 
review procedures. 
•  Prepare environmental reviews concurrently with one another, rather than 
consecutively. 
•  Establish appropriate time limits on EISs. 
•  Integrate the NEPA process into early planning and prepare the EIS early in the 
process. 
•  Emphasize interagency cooperation before the EIS is prepared, rather than 
submission of adversary comments on a completed document. 
•  Insure the swift and fair resolution of lead agency disputes.81 
Environmental Protection Agency Functions Under NEPA 
NEPA is broad, with requirements potentially affecting all federal agencies. Also, EPA is not 
authorized to enforce NEPA’s requirements; instead, federal agencies are required to implement 
its requirements themselves.82 However, EPA does have two distinct roles in the NEPA process. 
The first regards its duty, under Section 309 of the Clean Air Act, to review and comment 
publicly on the environmental impacts of proposed federal activities, including those for which an 
EIS is prepared. After conducting its review, EPA rates two elements of the action: the adequacy 
of the EIS and the environmental impact of the action.83 The EIS may be rated “adequate,” “needs 
more information,” or “inadequate.” The lead agency would be required to respond appropriately 
depending upon EPA’s rating. With regard to rating the environmental impacts of an action, EPA 
would rate a project in one of the following four ways: lack of objections, environmental 
concerns, environmental objections, environmentally unsatisfactory. If EPA determines that the 
action is environmentally unsatisfactory, it is required to refer the matter to CEQ to resolve any 
interagency dispute. 
EPA’s second duty is an administrative one, in which it carries out the operational duties 
associated with the EIS filing process. In 1978, these duties were transferred to EPA by CEQ in 
accordance with a Memorandum of Agreement (MOA) entered into by EPA and CEQ. Under the 
terms of the MOA, EPA’s Office of Federal Activities is designated the official recipient of all 
EISs prepared by federal agencies. EPA maintains a national EIS filing system. By maintaining 
the system, EPA facilitates public access to EISs by publishing weekly notices in the Federal 
Register of EISs available for public review, along with summaries of EPA’s comments. 
                                                                  
81 40 C.F.R. §§1500.2 and 1500.4-1500.5 
82 In CEQ’s regulations (40 C.F.R. §1507.3), federal agencies were required to prepare their own NEPA procedures 
that address that agency’s compliance in relation to its particular mission.

Apart from these duties, like any other federal agency, EPA may participate in the NEPA process 
as a lead agency when it is sponsoring its own federal actions. Currently, NEPA documentation is 
required of EPA for research and development activities, construction of EPA facilities, 
wastewater treatment plant construction under the Clean Water Act, EPA-issued National 
Pollutant Discharge Elimination System (NPDES) permits for new sources,84 and for certain 
projects funded through EPA annual Appropriations Acts. Legislation has specifically limited 
EPA’s requirement to comply with NEPA for certain actions. For example, Section 7(c) of the 
Energy Supply and Environmental Coordination Act of 1974 (15 U.S.C. 793(c)(1)) exempts 
actions taken under the Clean Air Act from the requirements of NEPA. EPA is also exempted 
from the procedural requirements of environmental laws, including NEPA, for response actions 
pursuant to requirements under the Comprehensive Environmental Response, Compensation, and 
Liability Act (CERCLA). Courts also have consistently recognized that EPA procedures or 
environmental reviews under enabling legislation are functionally equivalent to the NEPA process 
and thus exempt from the procedural requirements in NEPA. 
                                                                  
84 Such permits are more likely to be issued by states authorized to implement provisions of the Clean Water Act, and 
hence would not be considered “federal actions” subject to NEPA compliance. Section 511(c) of the Clean Water Act 
exempts other EPA actions under the law from the requirements of NEPA.
