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.
- PGP coverage is based on two unique criteria: single county vs. multi county and the number of acres to which pesticides will be applied. Detailed information is provided in the PGP General Information.
