SB 537 revises Montana's marijuana tax revenue distribution, directing funds from the marijuana state special revenue account to new and existing state accounts. It requires transferring excess funds annually to specific accounts, including 12% to the HEART account for addiction treatment and mental health programs, 20% to wildlife habitat projects, and 14% to behavioral health initiatives. The bill also allocates funds for law enforcement canine training, sexual assault evidence kits, and homeless shelter support, while modifying existing transfer rules for agencies like the Department of Fish, Wildlife, and Parks. These changes apply to all state agencies receiving marijuana tax revenue under Montana law.
HB 368 requires operators of coal-fired power plants (over 200 megawatts) in Montana to provide ongoing water access for residential and commercial use to the city or town where the plant is located if the plant closes. It mandates operators maintain water delivery systems until cleanup meets environmental standards, with financial assurance for water supply 30 years after closure. The bill directly affects plant operators and local governments, ensuring continued municipal water access even after plant retirement. Key provisions include revised definitions for "retired" plants, cleanup criteria, and requirements for operators to cover long-term water needs.
SB 472 removes the previous $250,000 cap on civil penalties for repeated violations of Montana's stream protection rules (under the Natural Streambed and Land Preservation Act). It specifically exempts forest activities that follow state forestry rules from these penalties. The bill affects developers, loggers, or others working in stream zones who violate permit requirements, allowing penalties to grow without limit for ongoing violations. It takes immediate effect upon approval.
SB 304 revises Montana's Lakeshore Protection Act to strengthen oversight of development near lakes. It directly affects landowners, developers, and contractors working within 20 feet of a lake's mean high-water elevation. Key provisions include requiring stop-work orders for unauthorized construction, mandating financial guarantees (surety bonds) for permits, updating penalties for violations (up to $10,000 fines or 180-day work pauses for repeat offenses), and allowing local governments to place liens on property to cover cleanup costs and fines. The bill also clarifies definitions, such as requiring lakes to be at least 160 acres and navigable by small boats, to determine which water bodies are protected.
SB 427 establishes minimum distance requirements for trapping on Montana's public lands near developed areas. It requires trappers to set traps at least 50 feet from roads/trails, 1,000 feet from campgrounds/recreation sites (including boat ramps), and 300 feet from trailheads (with 1,000 feet for lethal traps). The bill directly affects trappers operating on public lands, particularly those near popular recreation areas, and gives the Fish, Wildlife and Parks Commission authority to adjust these distances in high-use zones. The provisions aim to reduce conflicts between trapping activities and public recreation by creating physical buffers around developed sites.
SB 473 prohibits most weather modification activities in Montana, specifically banning large-scale "geoengineering" projects like spraying particles into the atmosphere to alter climate (e.g., stratospheric aerosol injection or marine cloud brightening). It exempts established cloud seeding practices used for agriculture and snowmaking under existing law (85-3-101 through 85-3-424). The bill directly affects researchers, companies, or entities conducting weather-altering experiments within Montana’s borders. Key provisions ban intentionally releasing chemicals or devices for weather control, temperature modification, or sunlight intensity changes, except for permitted cloud seeding. The law takes immediate effect upon enactment.
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.
House Bill 176 (HB 176) revises Montana's wolf hunting laws, primarily affecting the Fish and Wildlife Commission, wolf hunters, trappers, and landowners. The bill mandates an unlimited statewide gray wolf hunting quota when the state's wolf population reaches or exceeds 450 wolves. Under this quota, the Commission must authorize multiple hunting licenses per applicant, allow an individual to harvest an unlimited number of wolves, permit the use of bait for hunting or trapping, and allow night hunting on private lands with artificial light or night vision scopes. It also requires consistent data modeling for wolf population estimates.
HB 57 would amend Montana law to officially include California quail and Gambel's quail in the state's definition of "upland game birds" under Section 87-2-101, MCA. This change would directly affect hunters and wildlife managers by adding these quail species to the list of birds subject to regulated hunting seasons, bag limits, and conservation practices already applied to birds like pheasants and grouse. The bill specifically updates the legal definition without altering hunting seasons or regulations, ensuring these quail would be managed under existing upland game bird frameworks. The bill was introduced by request of the Environmental Quality Council but died in process on May 22, 2025.
HB 935 allows the department to temporarily suspend or close new permit applications for large groundwater appropriations (3,000 gallons per minute or more) from specific areas within the Fox Hills-Hell Creek aquifer. This action aims to balance water development with the protection of existing water rights. The bill also mandates the Bureau of Mines and Geology to conduct a feasibility study on groundwater availability in these areas. It appropriates $5,000 for this study, and the act's provisions are set to terminate on June 30, 2027.
