Comparison: State vs. Federal

Rules. Montana's rules for pesticides mirror federal regulations, especially the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) for pesticide management and the Resource Conservation and Recovery Act (RCRA) for pesticide disposal. MDA has specifically adopted the federal registration and labeling requirements as well as worker protection standards. Montana has additional pesticide applicator and dealer licensing requirements. See the national sections HAZARDOUS WASTE DISPOSAL and PESTICIDES for further information.

DEQ has developed a Montana Pollutant Discharge Elimination System (MPDES) general permit for discharges from applications of pesticides to surface waters of the state. For more information, see the state section
