NPDES Permit PA0087980 and WQM Permit 2898201. Agway Agricultural Products, 512 West King Street, Shippensburg, PA 17257, has submitted applications to the Department of Environmental Protection (Department) for an individual NPDES permit and a Water Quality Management (WQM) Part II permit relating to a concentrated animal feeding operation (CAFO). The CAFO will be located at 13655 Dream Highway in Lurgan Township, Franklin County. The CAFO will be in the Conodoguinet Creek watershed, which is classified as a warm water fishery. The individual NPDES permit application relates to the operation of the proposed CAFO and the WQM Part II permit application relates to the construction and operation of the manure storage and handling facilities at the CAFO.
The proposed CAFO will have 3,600 heifers ranging from 100 to 1,200 pounds. Two manure storage facilities with a total capacity of 9.1 million gallons will be constructed to serve the needs of the operation. Each manure storage facility will be a clay lined impoundment to comply with the requirements of the Pennsylvania Technical Guides. Groundwater monitoring will be provided in compliance with the requirements of the Department's Final Strategy for Meeting Federal Requirements for Controlling the Water Quality Impacts of Concentrated Animal Feeding Operations, 29 Pa.B. 1439 (March 13, 1999). The operation will be designed so that there will be no release or discharge to waters of this Commonwealth under normal operating conditions.
The Department has conducted administrative and technical reviews of the applications. On the basis of preliminary review and application of lawful standards and regulations and the Final CAFO Strategy, the Department has made a tentative decision to issue an individual NPDES permit PA0087980 and a WQM Part II permit 2898201 for the operation subject to the terms, conditions, limitations, monitoring and reporting requirements specified in the respective draft permits.
The proposed permits, the permit applications and associated material are on file at the Southcentral Regional Office of the Department. Persons may make an appointment to review the files by calling Mary DiSanto, File Review Coordinator, at (717) 705-4732.
The Environmental Protection Agency (EPA) permit review waiver provision under 40 CFR 123.24(e) does not apply to the General NPDES permit. The Administrator of EPA Region III may review or object to any proposed NPDES permit actions.
Persons wishing to comment on the proposed permit actions are invited to submit written comments to the previous address within 30 days from the date of this public notice. Comments received within this 30-day period will be considered in formulating the Department's final determinations regarding the application. Comments should include the name, address and telephone number of the writer and a concise statement to inform the Department of the basis of the comment and the relevant facts upon which it is based. A public meeting/hearing may be held if the Department considers the public response or interest significant.
Following the 30-day comment period, the Water Quality Management Program Manager will make the final determination regarding the proposed permits. Notice of this determination will be published in the Pennsylvania Bulletin at which time this determination may be appealed to the Environmental Hearing Board.
