Pesticide General Permit

The Permit Board on Environmental Quality reissued the statewide Pesticide General Permit (MSG23). The PGP covers the State of Mississippi and authorizes operators who discharge to waters of the State from the application of pesticides under the terms and conditions of the PGP. Activities covered by the permit include the application of pesticides to control: 1/ mosquito and other flying insects; 2/ weeds, algae, and pathogens; 3/ nuisance animal pests in water and at water’s edge; 4/ forest canopy pests; and 5/ other pests on a “case by case” basis to be evaluated individually. In addition to being consistent with product label application rates (authorized under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)), the permit requires eligible operators to implement site-specific control measures that minimize discharges of pesticides to waters of the State. In addition, large operators must develop and implement Pesticide Discharge Management Plans to prevent or mitigate pollutants from entering State waters. The term of the permit is for a five-year period.

This general permit will replace the previous general permit that expired September 30, 2016. The Pesticide General Permit can be viewed below.
