Subject: Request for Extension: Tenaska Fe rndale Cogeneration Station (ID: 06008) Ms. Alicea, The Tenaska Ferndale Cogeneration Station would like to request an extension to the 90 day requirement to complete the questionnaire aimed to assist in prep aration of effluent guidelin es and standards for the Steam Electric Power Generating Industry. The questionnai re package was received at the site June 21, 2010. Over the past few years Tenaska facilitie s have worked with both state agencies and EPA regions to

ensure each site has been correctly permitted; in multiple cases modifying or terminating permits after demonstrating that they fail to meet the “categor ical” definition. We would greatly appreciate the opportunity to confirm that a response from the site would be not only appropri ate but beneficial as new guidelines and standards are created. In addition, if it is deemed that a respon se would be appropriate our capital group will need to coordinate with the multiple partners to garner the economic information requested in Part I. We will be sending additional inform ation to illustrate our concerns r egarding the classification. If you have any questions, comments, or concerns in the interim please feel free to either email me at bwilton@tenaska.com or via telephone at (402)-218-8770.

Best regards,
