April 13, 1992 Mr. S. L. Pernick, Jr.

Manager, Environmental Af fairs Duquesne Light Company One Oxford Centre 301 Grant Street Pittsburgh, PA 15279 RE: Corbicula (Asiatic Clam) Control Program Deaver Valley Power Station NPDES PA0025615 Shippingport Borough Beaver County

Dear Mr. Pernick:

Your February 26, 1992 proposal to continue the use of Betz (CT-1) on an as-needed basis to control the asiatic clam in your water systems is hertby approved with the following -conditions:

1. This approval is contingent on our understanding that clamtrol will be used to treat small subsystems of the plant rather than the entire f acili ty. Since only small amounts of the material will _be used, there will be no need to absorb residual product on clay. In order for us to evaluate usage on an as-needed basis, you are required to submit quarterly reports on the amount of product used and the dates and times of product addition.- This information is to be recorded on the attached chemical additive monitoring report form. The reports are to be. submitted to tLe attention of the Chief of the Permits Section.

2.- Should it become necessary to treat either facility with a mega dose of the additive and the clay, you must notify the Departme- ; at least fourteen (14) days in advance. The applicable effluent limitations and monitoring requirements shall be similar to our April 10, 1991 and May 1, 1991 approvals. Any requests to treat the entire plant must include plans for conducting clam growth studies in the Ohio River before, during and af ter the dosing.
