Final General Permit
Pesticide Application Discharges
Effective Date: October 31, 2011
Expiration Date: October 31, 2016
Ohio EPA has issued a final general National Pollutant Discharge Elimination System (NPDES) permit that may potentially provide coverage for the application of a pesticide to target a pest that is present in, over or near waters of the U.S. in the State of Ohio.
This permit is mandated by federal court decisions. Pesticide application must have an NPDES permit beginning April 9, 2011, if they occur “in, over or near” surface waters. This includes applications to ditch banks and aerial spraying and fogging. The permit covers the same four pesticide use categories that the federal program covers: Mosquito and Other Aquatic Nuisance Insect Control, Aquatic Weed and Algae Control, Area-Wide Pest Control, and Aquatic Nuisance Animal Control.
