Indiana Michigan Power Cotnpany Cook Nuclear Plant One Cook Place Bridgrnan, Ml 49t06 616 465 5901 HP INDMNA MICHIGAN POWER Mr; Fred Morley, District Supervisor Surface Water Quality Division Michigan Department of Natural Resources 621 North Tenth Street P.O. Box 355 Plainwell, MI 49080 September 8, 1995 Re: Cook Nuclear Plant NPDES Permit No. MI0005827 Hydraulic Oil Spill
Dear Mr. Morley:
The following notification is being performed per NPDES Permit MI0005827, Part II. Section A.6., Spill Notification. The spill was previously reported via.
telephone calls to Mr. Greg Danneffel of the Michigan, DNR Plainwell office at 2:00 p.m. and Mr. Carroll of the Response Center at 5:10 p.m., on August 29, 'ational 1995 (Report g305645.)
The spill occurred at approximately 8:30 a.m. on August-.
29, 1995, while divers were using hydraulic brushes to remove zebra mussels from the Cook Nuclear Plant's screenhouse intake forehay walls. The hydraulic line burst'nd released approximately 2 gallons of, hydraulic.'il to the intake forehay. The divers immediately shut down the hydraulic scrubbing unit and removed the water. Oil absorbent hooms were deployed into the it from forebay to clean up the surface oil sheen.
Samples of the Unit 2 discharge indicated no trace of oil in the sample. Plant personnel launched an inflatable boat to inspect the discharge for signs of an oil sheen on Lake Michigan. The discharge plume was traversed and very small wisps of oil were noted extending south of the discharge. The lake was very calm during the inspection.
