1. In June of 2000, Braidwood Station inadvertently discharged approximately 4,000 gallons of mostly diesel oil from the oil water separator used by the site's storm drainage system. The oil water separator discharged into the north perimeter drainage ditch. A report was not issued as required by Appendix B, Section 4.1, nor was a follow-up report submitted within 30 days as required by Appendix B, Section 5.4.2.

ATTACHMENT C List of non-compliances to the Environmental Protection Plan and the corrective actions

1. Contrary to the requirements of Appendix B, Section 3.2, "Reporting Related to the NPDES Permit and State Certification" of Braidwood Station's Facility Operating License, Braidwood Station did not notify the NRC of changes to the National Pollutant Discharge Elimination System (NPDES) permit when applied for in 1997. A copy of the permit is included in this report as Attachment D.

Gentlemen:

The Illinois Environmental Protection Agency has reviewed the request for modification of the above-referenced NPDES Permit and issued a public notice based on that request. The final decision of the Agency is to modify the Permit as follows:

The monitoring frequency for oil and grease is being reduced from 1/week to 1/month for Outfalls 001(a) and 001(c). Additional monitoringrequirements arebeingaddedto Outfall 001, concemingtheusage of bromine based biocides. The elimination of fecal coliform monitoring at Outfall 00 1(b) due to the facility being granted a year-round disinfection exemption in July, 1995.

Enclosed is a copy of the modified Permit. You have the right to appeal this modification to the Illinois Pollution Control Board within a 35 day period following the modification date shown on the first page of the permit.

Should you have any question or comments regarding the above, please contact Darin LeCrone of my staff.

A. Maximum temperature rise above natural temperature must not exceed 50F (2.8 DC).

B. Water temperature at representative locations in the main river shall not exceed the maximum limits in the following table during more than one (1) percent of the hours in the 12-month period ending with any month. Moreover, at no time shall the water temperature at such locations exceed the maximum limits in the following table by more than 30 F (1.70C).

The reported mean concentration and maximum concentration of Total Residual Chlorine/Total Residual Oxidant fTRC/TRO) shall be based on a minimum of three grab samples taken at approximately five minute intervals at Outfall 001. The time

'samples were collected, the time and duration of oxidant dosing period plus the monthly average and daily maximum amount of oxidant applied shall be reported on the Discharge Monitoring Reports. The reported average concentration of TRC/TRO is the average of all values measured for a sampling event and the reported maximum concentration is the highest value measured for a single grab sample. Discharge Monitoring Reports shall indicate whether bromine and/or chlorine compounds were used during the month. A discharge limit, as measured at the blowdown to the Kankakee River, of 0.05 mg/I (instantaneous maximum) shall be achieved for total residual oxidant (total residual chlorine/total residual halogen) when bromine biocides are used for condenser biofouling control.

SPECIAL CONDITION 5. There shall be no discharge of polychlorinated biphenyl compounds.

SPECIAL CONDITION 6. There shall be no discharge of complexed metal bearing wastestreams or associated rinses from chemical metal cleaning unless this permit has been modified to include the new discharge.

SPECIAL CONDITION 7.

A. Intake impacts will be reduced by limiting pumping from the river during the peak entrainment period. For a four-week period (last three weeks in May and first week in June), pumping will be allowed only during the day (between one hour after sunrise and one hour before sunset). In addition, during the four-week period, pumping will be minimized during the day. Pumping will occur when needed to fill the freshwater holding pond and to maintain efficient operation of the cooling pond. In an extreme emergency, and upon immediate notification of the Agency, pumping could occur at night. Such pumping would cease as soon as the emergency was over. Records of all pumping during the four-week period will be maintained. Such records will include dates, number of pumps operating and start and end times.
