MEMORANDUM 

TO: Steam Electric Rulemaking Record 

FROM: Danielle Lewis, ERG 

DATE: 30 September 2015 

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, previous rulemakings, and industry-submitted data provided in comments to the proposed 

ELG to estimate pollutant discharge loadings associated with the discharge of FGD wastewater, 

fly ash transport water, bottom ash transport water, and combustion residual leachate.1

 In 

addition, EPA estimated the corresponding pollutant removals associated with installing and 

operating the BAT technology options evaluated as part of the final ELGs for each of these 

wastestreams. ERG developed a computerized loadings model to calculate plant- and pollutantspecific pollutant discharge loadings for 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 Effluent Limitations 

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

(DCN SE05904) and the Incremental Costs and Pollutant Removals for the Final Effluent 

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

Category (DCN SE05831). 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 Regulatory 

Options A, B, C, D, and E.2

 

 

1

 All currently operating gasification generation units use evaporation treatment systems and all plants currently 

generating FGMC wastes operates such that there is no pollutant discharge to surface waters. Therefore, EPA 

determined that the gasification wastewater and FGMC wastewater baseline loadings are equal to the postcompliance loadings. 

2

 During development of the final rule, EPA decided not to base the final rule on Option F for existing sources due 

primarily to the high cost of that Option, particularly in light of the costs associated with other rulemakings expected 

to impact the steam electric industry (see Section VIII.C.1 of the preamble). As a result, EPA chose not to conduct 

particular analyses for Option F to the same extent that it did for some of the other options considered.

As discussed in both the Technical Development Document for the Effluent Limitations 

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

(DCN SE05904) and the Incremental Costs and Pollutant Removals for the Final Effluent 

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

Category (DCN SE05831), EPA estimated pollutant loadings several different ways to evaluate 

the effect of the final ELG on the steam electric industry. EPA considered other rulemakings 

affecting the steam electric industry in its analysis. Under one approach, EPA evaluated pollutant 

loadings taking into account changes that plants may make to implement the coal combustion 

residuals (CCR) rule (but not the Clean Power Plan (CPP)). Under a second approach, EPA 

evaluated compliance costs and pollutant loadings taking into account changes that plants may 

make to implement both the CCR rule and the CPP.3 The following tables present the pollutantlevel results from the loadings analysis: 

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

accounting for CCR and CPP; 

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

accounting for CCR and CPP; 

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

accounting for CCR and CPP; 

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

accounting for CCR and CPP; 

 Table 5: Industry-level pollutant-specific removals achieved under Regulatory Option D 

accounting for CCR and CPP; 

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

accounting for CCR and CPP; 

 Table 7: Industry-level baseline loadings by pollutant for all four wastestreams 

accounting for CCR; 

 Table 8: Industry-level pollutant-specific removals achieved under Regulatory Option A 

accounting for CCR; 

 Table 9: Industry-level pollutant-specific removals achieved under Regulatory Option B 

accounting for CCR; 

 Table 10: Industry-level pollutant-specific removals achieved under Regulatory Option C 

accounting for CCR; 

 Table 11: Industry-level pollutant-specific removals achieved under Regulatory Option D 

accounting for CCR; and 

 Table 12: Industry-level pollutant-specific removals achieved under Regulatory Option E 

accounting for CCR.

 At the time it conducted these analyses, the CPP had not yet been finalized, and thus EPA used the proposed CPP 

for its analyses.
