This office has under consideration the application of:

Applicant: Point Sources Applying Pesticides to Waters of the State
Location: State of Delaware
Parcel(s): N/A

Project Description: National Pollutant Discharge Elimination System (NPDES) General Aquatic Pesticides Permit Number DE 0051241 (Authorization for Point Source Discharges from the Application of Pesticides to Waters of the State).

The Delaware Department of Natural Resources and Environmental Control (DNREC) is providing public notice for the renewal of Draft National Pollutant Discharge Elimination System (NPDES) General Permit for the application of Aquatic Pesticides. This notice is for the General Permit itself. Once a General Permit is issued, an applicant can obtain coverage under this General Permit by submitting a completed Notice of Intent and Pesticide Discharge Management Plan, if applicable, for DNREC review and approval.

An Aquatic Pesticides permit is a point source permit authorized by the Federal Clean Water Act that is required by Federal and State regulations for operators that apply biological or chemical pesticides that leave a residue directly to Waters of the State or indirectly to systems that discharge into Waters of the State. In the State of Delaware, DNREC implements the Aquatic Pesticides NPDES program. The purpose of the Aquatic Pesticides permit is to regulate activities involving the application of pesticides near and on Waters of the State and to help improve and maintain the quality of Waters of the State. On the basis of a preliminary staff review and application of lawful standards and regulations, DNREC proposes to issue general Aquatic Pesticides permit coverage to the applicable operators, subject to certain effluent limitations and conditions in this permit.
