MEMORANDUM 

TO: Steam Electric Rulemaking Record 

FROM: TJ Finseth, ERG 

DATE: 19 April 2013 

SUBJECT: Steam Electric Pollutant-Level Loadings and Removals for Each 

Wastestream and Regulatory Option 

ERG is providing technical support to the U.S. Environmental Protection Agency’s Office of 

Water, Engineering and Analysis Division (EAD) for development of effluent limitations 

guidelines and standards (ELGs) for the Steam Electric Power Generating Industry. EPA, with 

the support of ERG, evaluated wastewater flow rates and pollutant concentration data from 

survey responses, site visits, sampling episodes, trade associations, individual power plants, 

states, and previous rulemakings to estimate pollutant discharge loadings associated with the 

discharge of FGD wastewater, fly ash transport water, bottom ash transport water, and 

combustion residual landfill leachate. In addition, EPA estimated the corresponding pollutant 

removals associated with installing and operating the proposed candidate BAT technology 

options for each of these wastestreams. ERG developed a computerized loadings model to 

calculate plant- and pollutant-specific pollutant discharge loadings for all power plants reported 

to be discharging these wastestreams. 

The industry-level baseline loadings and removals for each wastestream and regulatory option 

are presented in both the Technical Development Document for the Proposed Effluent 

Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source 

Category and the Incremental Costs and Pollutant Removals for the Proposed Effluent 

Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source 

Category. However, those reports do not present the pollutant-level loadings for each 

wastestream and regulatory option. This memorandum presents the pollutant-level baseline 

loadings for each wastestream, as well as the pollutant-level removals achieved under each 

regulatory option by wastestream. The following tables present the pollutant-level results from 

the loadings analysis: 

 Table 1: Industry-level baseline loadings by pollutant for all four wastestreams; 

 Table 2: Industry-level pollutant-specific removals achieved under Regulatory Option 1; 

 Table 3: Industry-level pollutant-specific removals achieved under Regulatory Option 3a; 

 Table 4: Industry-level pollutant-specific removals achieved under Regulatory Option 2; 

 Table 5: Industry-level pollutant-specific removals achieved under Regulatory Option 3b; 

 Table 6: Industry-level pollutant-specific removals achieved under Regulatory Option 3; 

 Table 7: Industry-level pollutant-specific removals achieved under Regulatory Option 4a;
