Montana Pesticide General Permit

The Montana Pesticide General Permit (PGP) is the permitting mechanism for anyone who applies pesticides into or over state surface water.  The PGP is not a pesticide permit; it is a wastewater discharge permit regulated under the Montana Department of Environmental Quality (DEQ) Montana Pollution Discharge Elimination System (MPDES) program.  Discharge of pollutants to state water without a permit is a violation of the Montana Water Quality Act in 75-5-605, Montana Code Annotated (MCA).

A Notice of Intent (NOI) submittal is required before pesticide is applied to or over surface water.  The NOI is a legal notification by the owner/operator to DEQ that they will comply with the PGP.  If the application of pesticides occurs within the boundaries of Indian Lands, the owner/operator will need to comply with the permit requirements of the EPA’s Pesticide Program.

On April 9, 2011, the Montana Department of Environmental Quality (DEQ) issued the final Pesticide General Permit (PGP).  Below are documents related to the permit issuance:
