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 11 05 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.
