      "title": "Air Pollution Emission Control: Existing Technologies and Mercury Cobenefits",
      "summary": "The Environmental Protection Agency (EPA) regulates the amount of pollution emitted into the\natmosphere by stationary combustion sources. To meet these regulations, stationary sources use\nvarious techniques to reduce air pollutant emissions, including installing post-combustion emission\ncontrol technologies. Some post-combustion technologies reduce the emissions of other pollutants\nbesides the one for which they are designed. These concomitant reductions are called cobenefits. \nThe EPA has proposed regulating mercury emissions from coal-fired electric power plants by relying\non the results that these post-combustion emission control technologies achieve through cobenefits. \nThe appropriateness of using cobenefits to set emission limits, the reproducibility and reliability of\ncobenefits, and the likelihood that new technologies specifically designed to reduce mercury\nemission will be commercially available in the near future are issues of congressional interest. This\nreport will not be updated.",
