TO: Steam Electric Effluent Guideline Rulemaking Record

FROM: Danielle Lewis, ERG

DATE: September 30, 2015

SUBJECT: Supplemental Costs and Loadings Documentation (DCN SE05839)

EPA’s report “Incremental Costs and Pollutant Removals for the Proposed Effluent Limitations

Guidelines and Standards for the Steam Electric Power Ge nerating Point Source Category”

(DCN SE05831) describes the methodologies used to estimate engineering compliance costs

associated with installing and operating the various technol ogies and practices that make up the

regulatory options considered by EPA. That report also prese nts the methodologies used to

estimate baseline and post-compliance pollutant loadings and the corresponding pollutant

removals for each regulatory option.

ERG prepared this document as a complement to that report , providing additional detailed

information and data regarding the steam electric costs and loadings. This document, consisting

of a compilation of appendices to this cover memorandum, includes the following types of

additional detailed information and data:

• Spreadsheets documenting development of input tables, cost factors, chemical dosage

rates, and other cost elements;

• Telephone contact reports and other detailed cost inform ation provided by vendors;

• Equipment specifications provided by vendors; and

• Calculations performed using the cost information, including the generation of cost

curves.
