Re: Commonwealth Edison Company Byron Station NPDES Permit No. ILOO48313 Modification of NPDES Permit (After Public Notice)

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:

1.

To allow the continued use of bromine compounds for biofouling control.

2.

To include a schedule for meeting a 0.05 mg/l TRO limit by installing debromination facilities.

3.

To include storm water requirements.

Enclosed is a copy of the modified Permit. You have the right to appeal this modification to the Illinois Pollution Control Board within a 30 day period following the modification date shown on the first page of the permit.

Should you have ar.y question or comments regarding the above, please contact Tim Kluge of my staff.
