Subject:

Limerick Generating Station NPDES Permit No. PA0051926 Pursuant to Chapter 92.7, " Reporting of New or increased Discharges," we are requesting the subject permit be amended to allow the use of the chemical additive Betz Bio-Trol 88P in the cooling water system at Limerick Generating Station. The additive will be used as an attemative to the chlorine and bromine system currently permitted for control of condenser biofouling. Current permit discharge limits for total residual oxidants (TRO) should be applicable for the Betz product.

Usage rate of Bio-Trol 88P is estimated to be 400 lbs/ day as a maximum. This will result in a maximum residual of 0.2 mg/l or less as TRO at outfall 001. As stated earlier, this is consistent with current permit conditions. The additive has been approved by the Depatiment for use at Cromby, Delaware, Schuylkill and Eddystone Stations. Enclosed are the Material Safety Data Sheet and Aquatic Toxicity Data for the additive.

Based on this information and due to recurring problems with the current chlorine and bromine system, we would appreciate a favorable response by November 2,1995.

A copy of this letter (including any attachments or enclosures) is being sent to the U.S.

Nuclear Regulatory Commission (USNRC) in accordance with the Limerick Generating Station, Units 1 and 2, Environmental Protection Plan, Section 3.2, which stipulates that USNRC shall receive a copy of any proposed changes to the NPDES permit at the same time that the permitting agency is notified.

If you have any questions or require additionalinformation, please contact me at (215) 841-5177.

Sincerely, SW Robert M. Matty, r.
