Generally revise gravel pit laws
SB 460 would have required Montana's Department of Environmental Quality to ensure protection of surface and groundwater from open-cut mining operations. The bill amended state law to specifically mandate the department adopt rules for permits, records, and inspections, and to enforce water quality and quantity standards during mining activities. This would directly affect open-cut mining operations statewide by imposing new regulatory requirements on their water protection measures. The bill did not advance beyond committee and died in the 2025 legislative session.
