The definition of operator in 9VAC25-800-10 provides that more than one person may be responsible for the same discharge resulting from pesticide application. Any operator authorized to discharge under this general permit is responsible for compliance with the terms of this permit for discharges resulting from the application of pesticides.
Table 1. Annual Treatment Area Thresholds | |
Pesticide Use | Annual Threshold |
Mosquito and Other Flying Insect Pest Control | 6400 acres of treatment area1 |
Weed and Algae Pest Control | 80 acres of treatment area1 or 20 linear miles of treatment area2 |
Animal Pest Control | 80 acres of treatment area1 or 20 linear miles of treatment area2 |
Forest Canopy Pest Control | 6400 acres of treatment area1 |
Intrusive Vegetation Pest Control | 6400 acres of treatment area1 or 20 linear miles of treatment area2 |
1Calculations include the area of the applications made to: (i) surface waters and (ii) conveyances with a hydrologic surface connection to surface waters at the time of pesticide application. For calculating annual treatment area totals, count each pesticide application activity as a separate activity. For example, applying pesticides twice a year to a 10-acre site is counted as 20 acres of treatment area. | |
2Calculations include the extent of the application made to linear features (e.g., roads, ditches, canals, waterways, and utility rights of way) or along the water's edge adjacent to: (i) surface waters and (ii) conveyances with a hydrologic surface connection to surface waters at the time of pesticide application. For calculating annual treatment totals, count each pesticide application activity or area as a separate activity. For example, applying pesticides twice a year to a one mile linear feature (e.g., ditch) equals two miles of treatment area regardless of whether one or both sides of the ditch are treated. Applying pesticides twice a year along one mile of lake shoreline equals two miles of treatment area. |
If the proposed discharge would not be eligible for coverage under this permit because the surface water is listed as impaired for that specific pesticide, but the applicant has evidence that shows the water is no longer impaired, the applicant may submit this information to the department and request that coverage be allowed under this permit.
