Williams Marks Acting Technical Secretary Michigan Water Resources Commission Stevens T. Mason Building P.O. Box 30028 Lansing, Michigan 48926 Re: D. C. Cook Nuclear Plant NPDES Permit No. 0005827 Groundwater Limitation .

Dear Mr. Marks:

At approximately 0530 hours0.00613 days <br />0.147 hours <br />8.763227e-4 weeks <br />2.01665e-4 months <br /> on November 5,1983, the recording pH meter which controls the valve allowing turbine room sump effluent to be pumped to the plant's absorption pond was found to be inoperative. The isolation valve was immediately closed since pH of the sump was unknown.

At approximately 1030 hours0.0119 days <br />0.286 hours <br />0.0017 weeks <br />3.91915e-4 months <br /> the isolation valve was found open. The newly repaired pH meter was indicating a pH of 2.8. The valve was again closed in order to find out why the valve had been opened with a sump pH lower than 5.5.

It was determined that a high level alarm had been received, and to prevent flooding, the operator utilized the reading of the pH meter on the automatic neutralizer (which read 7.0) in place of "out of service" sump pH meter, and, believing a reading of 7.0 to be within allowable limits, opened the valve to clear the alarm and pump out the sump. The automatic neutralizer pH meter however was found to be out of calibration and the sump pH actually lower than-indicated.

The volume of sump effluent pumped to the pond where dilution occurs is insignificant when compared to the total absorption pond volume. Calibration of pH meters has been checked and the communications procedures between lab technicians and operators are being examined.

Very truly yours,

/
