Description
Excerpt: The EPA Base Case 2000 includes emission control technologies as compliance options for meeting air regulatory requirements. Although the EPA Base Case 2000 includes only existing SO2 and NOx air regulations, detailed assumptions on the cost and performance for mercury control were developed for use in mercury policy cases built on EPA Base Case 2000. In addition, two other control options — combustion optimization and biomass co-firing — are offered for policy scenarios where such control options might be applicable.
