Fact Sheet

Notice is hereby given that DNREC intends to issue two General Permits related to the NPDES CAFO program. A CAFO permit is a point source permit authorized by the Federal Clean Water Act that is required by Federal and State regulations for CAFOs that discharge pollutants into waters of the state, including streams or drainage ditches. DNREC intends to issue these General Permits, under which CAFO operations can seek discharge authorization. In the State of Delaware, DNREC and DDA cooperate in implementing the CAFO program. The purpose of the CAFO permit is to regulate activities at CAFOs involving the management of nutrients and to help improve and maintain the quality of waters of the state. Applicable farms will be subject to certain effluent limitations and conditions under Section 9.5 of 7 Del. Admin. Code §7201 – State of Delaware Regulations Governing the Control of Water Pollution.
