Subject:

Limerick Generating Station, Units 1 and 2 Changes to National Pollutant Discharge Elimination System Permit Gentlemen:

This letter is being submitted in accordance with the Limerick Generating Station (LGS), Units 1 and 2 Environmental Protection Plan (EPP) Section 3.2 , which stipulates that the NRC shall be notified within 30 days following the date of approval of a change to the National Pollutant Discharge Elimination System (NPDES) permit.

By letter dated May 8,1996, the Pennsylvania Department of Environmental Protection (PA DEP) approved PECO Energy Company's request to revise LGS NPDES Permit No. PA0051926 to '

permit the use of chemical additive Betz Deposi-Trol 855D in support of cleaning heat exchangers in the secondary cooling water systems at LGS, Units 1 and 2. This product was originally approved for use at LGS by the PA DEP in 1992; however, it was not included in the renewal of the LGS NPDES permit issued on January 1,1995. This product was approved as a development product (i.e., Betz DE-1579), but has been subsequently renamed to Betz Deposl-Trol 855D. There Is.og change in the chemical properties of the two (2) products. A copy of the PA DEP letter approving this change to the LGS NPDES permit is attached. The NRC was previously notified of our request to revise the NPDES permit to use Betz Deposi-Trol 855D by letter dated April 23,1996.

If you have any questions or require additional information, please do not hesitate to contact us.

Very truly yours,
