EPA has made available substantial data and other information relating to the proposed rule in the docket for the steam electric power generating effluent guidelines rulemaking, including data relating to the specific facility(ies) you identified, data about other plants where that data is not

claimed as confidential business information or coul d lead to the disclosure of confidential business information, equations used to estimate several key outputs such as costs, and a description of the various methodologies used by EPA (e.g., costing methodologies, p ollutant loadings methodologies, etc.). In addition to this publicly available data, in response to your request, EPA is planning to forward under separate correspondence additional data that provides plant

- specific compliance costs and pollutant removals that EPA estimated would be attributable to the proposed rule, as well as plant

- specific input values that were used in EPA's cost models, pollutant loadings/removal models, and environmental assessment models. EPA is planning to provide a description of how each plant can use available data to make relevant calculations, such as how to calculate pollutant loadings. EPA believes these data, in addition to the publicly available da ta already provided in the docket, provide you with sufficient information to understand any effects the proposed rul e may have on your facilities and to comment effectively on the proposed rule, and this data represents the extent of information that EPA can make available to you witho ut disclosing, directly or indirectly, information claimed as confidential business in formation by other sources.

Please include all information from these documents that relates to our facilities. For example, our facilities supplied inf ormation about existingcontrol technologies. Through this request, we are req uesting not only the control technologies information supplied by our facilities, but also

control technologies information about our facilities derived from other sources, as well as all EPA

- developed information relating to our control technologies, incl uding EPA's assessments of future technology choices for our facilities based on the various rule options. For each document, as appropriate, please also include: (1) a legend which explains each column heading and each abbreviatio n used throughout

the en tire document; and (2) a list of all formulas applied in the document and a legend for any abbreviations used in the formulas . The legend and formula information is key to understanding these documents. We make this request without waiving any of our CBI designations. Because you are providing the information only to us, there is no breach of confidentiality and no waiver of CBI protections. Furthermore, we are not requesting CBI information, or CBI

- derived information, from other companies that may have furnished data or information appearing in the listed documents. We are requesting only information related to our

own facilities. We have done our best to be selective in asking for facility

- specific information. The information we are seeking, however , is critical to our review of, and preparation of comments on, the proposed ELG Rule. Because there are less than 50 days left in the comment pe riod, we ask that you expedite this request. If you have any questions about this request, please call or emai l me. I look forward to your prompt response. Thank you very much for your help.

Sincerely,

W. Michael Winkler Manager, Environmental Programs LG&E and KU Energy
