INDIANA & MICHIGAN EIECTRIC COMPANY ONE SUMMIT SQUARE, P. O.,BOX 60, FORT WAYNE IN. C6601 Telephone: (219) 425.2111 July 11, 1985 RlCHrf RD C..h(EDGE Vice President Paul D. Zugger, Executive Secretary Michigan Water Resources Commission Stevens T. Mason Building, Box 30026 Lansing, Michigan 48909 Re: Donald C. Cook Nuclear Plant NPDES Permit No. MI 0005827 Groundwater Limitations

Dear M Zugger:

On June .'.1, 22 and 23, 1985 at approximately 0200 bours, and again on July 2, 1985 at 0835 hours0.00966 days <br />0.232 hours <br />0.00138 weeks <br />3.177175e-4 months <br />, the turbine room sump process pH meter was found inoperative due to the flow control valve being closed. Upon each discovery, the valve was immediately opened restoring flow to the pH meter re-establishing continuous pH monitoring.

During the periods the sump was without continuous pH monitoring, approximately 16,400 gallons, 35,700 gallons, 52,700 gallons, and 51,000 gallons, respectively were pumped from the sump to the plant absorption pond. In-line pH monitoring records indicate a pH in the required range prior to and after each event. It is believed that the required pH range was maintained during the interim periods.

An investigation is being made to determine if a "no flow" alarm can be installed in the control room to indicate the valve is closed and the meter is inoperable.

Very truly yours, Richard C. Menge Vice President cmk c: W. G. Smith I certify under penalty of law that I have personally examined and am familiar with the information submitted on this and all attached documents; and based on my inquiry of those individuals immediately responsible for obtaining the information, I believe the submitted information is true, accurate and complete.

I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment.

Richard C. Menge
