l NPDES Permit No. MI 0005827

Dear Mr. Adamkus:

Anticipating the outage of both nuclear units, the heating boiler l was drained to Lake Michigan in anticipation of start-up. A l sample of the effluent taken on December 27, 1984, prior to l mixing with cooling water, was found to.have an iron concentration of 3.1 ppm, exceeding the 1.0 ppm maximum daily limit.

l An NPDES modification which exempts the plant heating boilers i from iron and copper limits was approved by the Michigan Water l Resouces Commission on March 21, 1979, although the staff has l never formally modified the permit to reflect this administrative

, action. -

Very truly yours,
