NPDES Pesticide General Permit for Pesticides
This message is being sent as a reminder that the comment period for the proposed NPDES Pesticide General Permit ends March 2, 2011. See below for more information.

Oregon Department of Environmental Quality (DEQ) is proposing to issue a new National Pollution Discharge Elimination System (NPDES) Pesticide General Permit, and is now accepting public comments on this proposed permit. The NPDES permit is required under the US Clean Water Act for the purpose of protecting water quality. As a pesticide license holder, this permit may affect you if you apply pesticides for:

  • Mosquito and Other Flying Insect Pest Control.
  • Weed and Algae Control - invasive or other nuisance weeds, algae and pathogens in water and at the water’s edge*.
  • Nuisance Animal Control - invasive or other nuisance animals and pathogens in water and at the water’s edge.
  • Forest Canopy Pest Control.
  • Area Wide Pest Control - using aerial pesticide application to cover a large area to avoid substantial and widespread economic and social impact, when in order to target pests effectively, a portion of the pesticide unavoidably will be applied over and deposited in water.

*Irrigation districts formed under ORS 545 are not included under this permit. DEQ is developing a separate pesticide general permit for irrigation districts.

The full text of the proposed permit can be found here:

DEQ will accept public comments through 5 p.m. Wednesday, March 2, 2011. Public hearings will be held in Medford (2/24/2011) and Portland (2/28/2011). For more information and to view the public notice or other related documents, please visit:
