Box 1049 1800 Watermark Drive Columbus, Ohio 43266-0149 Re: Perry Nuclear Power Plant NPDES Permit Number 3IB00016*DD H-130 Addition for Zebra Mussel Control

Dear Mr. Magni:

l The Calgon Corporation has been enlisted to provide treatment for control of zebra mussels at the Perry Nulcear Dower Plant with their product, "H-130". The information in the enclos a attachments is provided for your review and approval prior to applying this treatment.

Attacht'ent 1 provides responses to the Ohio EPA questionnaire entitled

" Reporting and Testing Requirements for Cooling Water System Additives".

The proposed routing of the product is shown in Attachment 2. Water systems will be treated once in September at a concentration of approximately 5 mg/l for 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />. This program will be conducted by Calgon and plant personnel and monitored by plant environmental and l chemistry personnel.

l Calgon has also been enlisted to treat the cooling tower with an anti-foaming agent, "CL-37", should H-130 cause any concerns due to the t formation of foam during the treatment. Attachment 3 provides responses L to the Ohio EPA questionaire for this product.

l We feel that all the information needed to evaluate the use of Calgon

• Corporations "H-130" and "CL-37" at the Perry Power Plant is enclosed.

Our intention is to begin preparation for a treatment tenatively scheduled for September 11, 1991, pending your approval. We would

[ therefore appreciate your notifying us of the results of your evaluation

[ as soon as possible. Please call Louise Barton at (216) 259-3737 ext.
