Subject:

Notification of NPDES Permit Renewal for Exelon Generation Company, LLC, LaSalle County Station NPDES Permit No. 1 L0048151

Reference:

Letter from Alan Keller, PE., Division of Water Pollution Control, Illinois Environmental Protection Agency, dated March 28, 2007 In accordance with the 30 day notification requirements of Appendix B to Facility Operating Licenses NPF-1 1 and NPF-1 8, "Environmental Protection Plan," Section 3.2, "Reporting Related to the NPDES Permits and State Certification," notification is being provided of issuance of the final NPDES Permit for Exelon Generation Company, LLC, (EGC) LaSalle County Station (LSCS). The final permit issued was based on an NPDES Permit Renewal Application submitted to the Illinois Environmental Protection Agency (IEPA) on October 24, 2003.

The newly issued permit includes the following changes:

Special Condition 8 was revised by removing BAT/BCT language and substituting the Stormwater Pollution Prevention Plan Requirements. Specifically, LSCS is now required to develop a Stormwater Pollution Prevention Plan for storm water associated with industrial activity at the facility. In addition, LSCS has an annual requirement to submit a Stormwater plan facility inspection report to the IEPA.

Special Condition 9 was revised to include an annual reporting requirement to the IEPA summarizing the station's efforts with water treatment suppliers to find a suitable alternative to phosphorus based additives.

Cool

U. S. Nuclear Regulatory Commission April 27, 2007 Page 2 Backwash from the station's Makeup Water Greensand Filters was added as an input to Outfall 101. The additional discharge is from backwash activities associated with greensand filters that are used for cleanup of water from two deep groundwater wells.

The final permit enclosed is effective July 1, 2007 and has an expiration date of June 30, 2012.

Exelon Generation Company, LLC NPDES Permit No. IL0048151 Final Permit Gentlemen:

Attached is the final NPDES Permit for your discharge. The Permit as issued covers discharge limitations, monitoring, and reporting requirements. Failure to meet any portion of the Permit could result in civil and/or criminal penalties. The Illinois Environmental Protection Agency is ready and willing to assist you in interpreting any of the conditions of the Permit as they relate specifically to your discharge.

Special Condition 8 was revised by removing the BAT/BCT language and substituting the Stormwater Pollution Prevention Plan requirements.

The Agency has begun a program allowing the submittal of electronic Discharge Monitoring Reports (eDMRs) instead of paper Discharge Monitoring Reports (DMRs). If you are interested in eDMRs, more information can be found on the Agency website, http://epa.state.il.us/water/edmr/index.html.

If your facility is not registered in the eDMR program, a supply of preprinted paper DMR Forms for your facility will be sent to you prior to the initiation of DMR reporting under the reissued permit.

Additional information and instructions will accompany the preprinted DMRs upon their arrival.

The attached Permit is effective as of the date indicated on the first page of the Permit. Until the effective date of any re-issued Permit, the limitations and conditions of the previously-issued Permit remain in full effect. You have the right to appeal any condition of the Permit to the Illinois Pollution Control Board within a 35 day period following the issuance date.

Should you have questions concerning the Permit, please contact Leslie Lowry at the telephone number indicated above.

After such notification, the permittee shall make changes to the plan and shall submit a written certification that the requested changes have been made. Unless otherwise provided, the permittee shall have 30 days after such notification to make the changes.'

D.

The discharger shall amend the plan whenever there is a change in construction, operation, or maintenance which may affect the discharge of significant quantities of pollutants to the waters of the State or if a facility inspection required by paragraph G of this condition indicates that an amendment is needed. The plan should also be amended if the discharger is in violation of any conditions of this permit, or has not achieved the general objective of controlling pollutants in storm water discharges. Amendments to the plan shall be made within the shortest reasonable period of time, and shall be provided to the Agency for review upon request.

E.

The plan shall provide a description of potential sources which may be expected to add significant quantities of pollutants to storm water discharges, or which may result in non-storm water discharges from storm water outfalls at the facility. The plan shall include, at a minimum, the following items:

1.

A topographic map extending one-quarter mile beyond the property boundaries of the facility, showing: the facility, surface water bodies, wells (including injection wells), seepage pits, infiltration ponds, and the discharge points where the facility's storm water discharges to a municipal storm drain system or other water body.

A tracking or follow-up procedure shall be used to ensure appropriate response has been taken in response to an inspection. Inspections and maintenance activities shall be documented and recorded.

Page 10 NPDES Permit No. IL0048151 Special Conditions G. The permittee shall conduct an annual facility inspection to verify that all elements of the plan, including the site map, potential pollutant sources, and structural and non-structural controls to reduce pollutants in industrial storm water discharges are accurate. Observations that require a response and the appropriate response to the observation shall be retained as part of the plan. Records documenting significant observations made during the site inspection shall be submitted to the Agency in accordance with the reporting requirements of this permit.

H. This plan should briefly describe the appropriate elements of other program requirements, including Spill Prevention Control and Countermeasures (SPCC) plans required under Section 311 of the CWA and the regulations promulgated thereunder, and Best Management Programs under 40 CFR 125.100.
