  Control of Mercury Emissions From Coal-Fired Electricity Utility Boilers: Interim Report Including Errata Dated 3-21-02 (EPA/600/R-01/109) April 2002

In December 2000, EPA announced its intent to regulate mercury emissions from coal-fired electric utility steam generating plants. This report, produced by EPA's National Risk Management Research Laboratory, provides additional information on mercury emissions control following the release of "Study of Hazardous Air Pollutant Emissions From Electric Utility Steam Generating Plants – Final Report to Congress" in February 1998.

The first three chapters describe EPA's decision to regulate mercury under the National Emission Standards for Hazardous Air Pollutants provisions of the Clean Air Act, the use of coal in electric power generation, and the behavior of mercury in coal combustion. Chapters 4 through 9 report on:

  • Information on electric utility fuels, boilers, and emission control technologies
  • Mercury emissions associated with these diverse technology combinations
  • Results and implications of tests to evaluate the performance of mercury control technologies and strategies
  • Retrofit control cost modeling
  • Mercury behavior in solid residues from coal combustion

The final chapter summarizes current research and identifies future efforts needed to ensure cost-effective control of mercury emissions. References are provided at the conclusion of each chapter.
