      "title": "EPA's Tier 2 Emission Standards for New Motor Vehicles: A Fact Sheet",
      "summary": "The Clean Air Act Amendments of 1990 established \"Tier 1\" standards to limit tailpipe\nemissions\nfrom new motor vehicles. The law also required the Environmental Protection Agency (EPA) to\ndetermine if stricter controls would be necessary by model year (MY) 2004 to assist states in\nattaining or maintaining the National Ambient Air Quality Standards. EPA also was required to\nassess the availability and cost-effectiveness of technologies necessary to control emissions. In a\nreport submitted to Congress in August 1998, EPA concluded that tougher standards are necessary\nand that essential technologies are available and cost-effective.  (1)  As a result,\nEPA finalized stricter\n\"Tier 2\" standards on February 10, 2000.  (2)  The new standards will be\nphased in beginning in\nMY2004 and will require all new passenger cars and light trucks up to 8,500 pounds, and all new\nheavier passenger vehicles up to 10,000 pounds (including large sport-utility vehicles), to\ndemonstrate full compliance by MY2009. To improve the efficiency of emission control\ntechnologies, oil refiners also will be required to limit gasoline sulfur levels to an average of 30 parts\nper million (ppm) nationwide beginning in 2005, roughly 90% less than the current national average\nof 340 ppm.\n     1.  \u00a0EPA.
