I Indiana Michigan Power Company Cook Nuclear Plant One Cook Place

~ llridgman, Ml 49106 616 465 5901 INDIANA NICHIGAN POWER Mr. Fred Morley, District Supervisor Surface Water Quality Division Michigan Department of Natural Resources 621 North Tenth Street, P. O. Box 355 Plainwell, Ml 49080 September 21, 1995

Dear Mr. Morley:

Re:

Cook Nuclear Plant NPDES Permit No. Ml 0005827 This notification is provided as required by Part I, Section A. 1. (a.) (c.) of NPDES Permit MI0005827.

On September 16, 1995, at 0930 hrs., unnatural turbidity was observed at Cook Plant Outfalls 001 and 002 (condenser cooling water and miscellaneous low volume waste.)

The turbidity was observed during a molluscicide treatment being performed at the Cook Plant, in accordance with the conditions of our NPDES Permit.

On September 16, 1995, from 0920 to 2120 hrs., Nalco Macrotrol 9380 was applied for zebra mussel control in plant raw water systems.

The observed turbidity was caused by bentonite clay being fed into the discharge vaults for Units 1 and 2, during the molluscicide treatment.

Clay is used to satisfy the NPDES Permit detoxification requirements.

Clay feed was terminated at 2400 hrs. on September 16; a total of.

145,000 lbs. of bentonite clay were used to detoxify the molluscicide.

The turbidity observed during the molluscicide treatment was expected, since similar observations have been made during previous treatments.

Preventive actions are not possible due to the detoxiTication requirements contained in the NPDES Permit.

Should you have any questions, please contact John Garison at (616) 465-5901 ext. 1153, or me at (616) 466-2546.

Sincerely, j'Z ~
