~WER~Bridgman, Ml 49106 POMROAEP~com A unit of Amenican Electric Power June 13, 2007 AEP:NRC:2401-17 Docket Nos.: 50-315 50-316 U. S. Nuclear Regulatory Commission ATTN: Document Control Desk Mail Stop O-P1I-17 Washington, D.C. 20555-0001 Cook Nuclear Plant Units 1 and 2 SUBMITTAL OF NON-COMPLIANCE NOTIFICATION FOR NPDES PERMIT M10005 827 In a letter dated June 5, 2007, Indiana Michigan Power Company, the licensee for Cook Nuclear Plant (CNP) Units 1 and 2, submitted a non-compliance notification for National Pollutant Discharge Elimination System Permit M10005 827 to the Michigan Department of Enviromnmental Quality. On June 1, 2007, a plume from Stormwater Outfall 002S was observed in Lake Michigan. The source of the plume was from cooling system flushing operations. The flush water had mixed with the surrounding gravel and created turbid water that then overflowed the filter fence area of a main drain into a storm drain that did not have filter fabric on it. A plume was created when the turbid water was discharged to the lake. The failure was due to excessive flush water flow rates and clogged filter fabric on the main drains.

The flushing operations were stopped until remediations to the*

system could be made.

The filter fabric was replaced over the main drains, and the flushing rate was reduced. The flushing operation was placed back into service with no further issues.

In accordance with Section 3.2 of Part II of Appendix B of the Environmental Technical Specifications for CNP, a copy of the notification is included as an attachment to this letter.

This letter contains no new commitments. Should you have any questions or concerns regarding this notification, please contact Jon H. Harner, Environmental

Manager, at (269) 465-5901, extension 2102.
