Urgent: Request for Release of Information From Docket No. EPA-HQ-OW-2009-0819 ***PROMPT RESPONSE REQUESTED***

Dear Mr. Jordan and Mr. Covington: Our facilities provided information that is being used to inform EPA's development of the proposed revision of the effluent lim itations guidelines and standards for the steam electric power generating point sour ce (ELG Rule). The facilities listed below either responded to earlier ELG Rule questionnaires to the industry or provided information to you thr ough other means, such as site vi sits or separate information requests. The specific facilities in question are as follows: Louisville Gas & Electric Co. - Cane Run Station (KY0002062) Louisville Gas & Electric Co. - Mill Creek Station (KY0003221)

Louisville Gas & Electric Co. - Trimble County Station (KY0041971) Kentucky Utilities Co. - E.W. Brown Station (KY0002020) Kentucky Utilities Co. - Ghent Station (KY0002038) Kentucky Utilities Co. - Green River Station (KY0002011) Kentucky Utilities Co. - Ty rone Station (KY0001899)

We have identified certain record documents which we believe cont ain information reported by, or de rived from data or informati on reported by,

one or more of our facilities. EPA has red acted all or portions of these documents as "confidential business information" (CB I). We are requesting that you provide to us all information relate d to the facilities listed above (including information that EPA has derived from

information obtained from our facilities a nd from all other sources, and including f acility-specific or f acility-derived inform ation in input files to the listed documents) contained within the following documents:

Please include all information from these documents that relate s to our facilities. For exam ple, our facilities supplied infor mation about existing control technologies. Through this request, we are requesting not only the control t echnologies information supplied by our fa cilities, but also control technologies information about our facilities derived from other sources, as we ll as all EPA-developed information rela ting to our control technologies, including EPA's assessments of future technolog y choices for our facilities based on the various rule options. For each document, as appropriate, please also include: (1) a le gend which explains each column heading and each abbreviation used throughout the entire document; and (2) a list of all fo rmulas applied in the document and a lege nd for any abbreviations used in the form ulas. 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 reques ting CBI information, or CBI-derived informati on, from other companies that may have furnished data or information appearing in the listed documen ts. We are requesting only information re lated to our

own facilities.

We have done our best to be se lective in asking for facility-specific informati on. 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 peri od, we ask that you expedite this request. If you have any questions about this reque st, please call or email 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
