Dear Mr. Cauley:

Pursuant to PA Act 14, P.L. 834, we hereby notify you that the Exelon Generation, LLC. will be filing with the Pennsylvania Department of Environmental Protection (PaDEP) for renewal of an NPDES Discharge Permit at our Bradshaw Reservoir Facility. Renewal of the permit is required-to continue the discharge of water from the Bradshaw Reservoir site to the East Branch Perkiomen Creek.

Acts 67 and 68, which amended the Municipalities Planning Code to support sound land use practices and planning efforts, direct state agencies to consider comprehensive plans and zoning ordinances when reviewing applications for permitting of facilities or infrastructure, and specify that state agencies may rely upon comprehensive plans and zoning ordinances under certain conditions as described in Sections 619.2 and 1105 of the Municipalities Planning Code.

Enclosed is a General Information Form (GIF) we have completed for this project. DEP invites you to review the attached GIF and comment on the land use aspects of this project; please be specific to DEP when identifying any areas of conflict. If you wish to submit comments for DEP to consider in a land use review of this project, you must respond within 30 days to the DEP regional office listed below. If there are no land use comments received by the end of the comment period, DEP will assume that there are no substantive land use conflicts and proceed with the normal application review process.

Subject:

NPDES Permit Renewal for Bradshaw Reservoir, PA0052221

Dear Mr. Froio:

Pursuant to PA Act 14, P.L. 834, we hereby notify you that the Exelon Generatibn, LLC. will be filing with the Pennsylvania Department of Environmental Protection (PaDEP) for renewal of an NPDES Discharge Permit at our Bradshaw Reservoir Facility. Renewal of the permit is required to continue the discharge of water from the Bradshaw Reservoir site to the East Branch Perkiomen Creek.

Acts 67 and 68, which amended the Municipalities Planning Code to support sound land use practices and planning efforts, direct state agencies to consider comprehensive plans and zoning ordinances when reviewing applications for permitting of facilities or infrastructure, and specify that state agencies may rely upon comprehensive plans and zoning ordinances under certain conditions as described in Sections 619.2 and 1105 of the Municipalities Planning Code.

Enclosed is a General Information Form (GIF) we have completed for this project. DEP invites you to review the attached GIF and comment on the land use aspects of this project; please be specific to DEP when identifying any areas of conflict. If you wish to submit comments for DEP to consider in a land use review of this project, you must respond within 30 days to the DEP regional office listed below. If there are no land use comments received by the end of the comment period, DEP will assume that there are no substantive land use conflicts and proceed with the normal application review process.

Please submit any comments concerning this project within 30 days from date of receipt of this letter to the DEP Soils and Waterways Section.

For more information about this land use review process, please visit www.dep.state.pa.us (directLINK: "Land Use Reviews").

If you have any questions concerning the application, please contact Mr. Robert Alejnikov at (610) 718-2513.

Total Residual Oxidants Ihijection Non-Compliance LGS NPDES Permit #PA0051926 states that for Outfall 001, total residual oxidants may not be discharged from any unit for more than three hours in any one day and not more than one unit in any plant may discharge total residual oxidants at any one time.

On May 22, 2008, the injection control program for the Unit I chlorination system was unintentionally altered during a procedure validation activity, resulting in the injection pump failing to de-energize at the normal program end time (2010). The pump continued to run until approximately 0100 on May 23, 2008. This resulted in the system operating for approximately 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> longer than the allotted 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> duration. Additionally, this operating period overlapped with a Unit 2 chlorination cycle.

Immediate actions taken upon discovery of the situation included: reviewing the timer program to verify omission of the step that secures the injection pump; confirming by data review that TRO levels (<0. 1 mg/I) were below the limit of 0.2 mg/l; removing the system from service until a complete review of the scenario was complete; and conducting a prompt investigation, which included interviewing involved personnel, to gain a complete understating of the event.

Scheduled corrective actions to preclude reoccurrence include a procedural enhancement, which requires a peer review of the timer sequence program steps, prior to returning the system to service.

A courtesy notification was made to Tom Magge of the Southeast Region PADEP Operations Section, on 5/23/08 at 1535.
