c Filo No P10.2.1 Incident No: PAL-85-02-AD108 NPDES NOTIFICATION Apparent Difference From Daily Average / Maximum Limitation March 19, 1985 Permit No: MI 0001457 Plant: Palisades Outfall
Description:
Turbine Sump Oil Separator Outfall Code No: 800218 Discharge (00G) i Parameter: Oil and Grease (Freon)
Parameter Code No:
00556 1.
Date of Incident:
2/28/85 2.
Identification of specific effluent limitation or monitoring requirement affected:
Oil and grease monthly average limitation of 15 mg/1.
3.
Description of Incident:
The monthly average oil and grease for February 1985 neasured 27.3 eg/1.
4 Apparent Cause:
The monthly average limitation was exceeded as a result of an apparent malfunction of the new oil / water separator during the first half of the month, which caused the daily maximum limit to be exceeded on February 4, 10 and 11, 1985. As previously reported, there was a carry-over of oil from the separator into Tank T-41.
5.
If not immediately corrected, the anticipated time the condition is expected to continue:
We believe that some of the basic problems have been resolved. The last two samples for the month of February were in compliance.
6.
Corrective Action - The following corrective action was taken or will be taken to reduce, eliminate and prevent recurrence:
i As previously reported, performance of the new API oily waste treatment system continues to be evaluated and fine tuned to plant operations. As a result of the high readings, the interior of the separator was cleaned and accumulated oil removed from Tank T-41.
The separator's oil skimming weir was also readjusted to manufacturer's specifications. System performance samples were collected and are being analyzed.
7.
Additional Comments:
At no time was oil visible on the receiving waters of Lake Michigan.
