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.
Montana's SJ 14 is a state legislative resolution requesting the federal government release over 660,000 acres of designated wilderness study areas from consideration for inclusion in the National Wilderness Preservation System. It specifically targets seven Montana wilderness study areas (including West Pioneer, Sapphire, and Big Snowies) and 37 Bureau of Land Management wilderness study areas that have remained in legal limbo since the 1977 Montana Wilderness Study Act. The resolution argues these lands are hindering multiple-use management (like timber harvesting and agriculture) and causing federal management uncertainty, and asks for their formal release to allow standard federal land management under the National Forest Management Act. The resolution was tabled in committee and died in process in 2025, so it has not become law.
SB 294 requires Montana's public utilities (like electricity providers) to create a detailed plan by May 2026 showing how they will source 100% of their retail electricity from renewable energy (including hydroelectric power) and reduce greenhouse gas emissions. The plan must outline specific options, timelines, and challenges for achieving these goals, aligning with Montana's constitutional duty to protect the environment. Utilities must submit these plans to the Energy and Telecommunications Interim Committee by June 2026, which will review them, gather public input, and recommend changes to the next legislature. The bill takes immediate effect upon passage but is currently inactive after dying in committee.
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.
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.
HB 31 clarifies and revises the bonding requirements for wind and solar generation facility owners in Montana to ensure proper decommissioning. It mandates that facility owners submit a decommissioning plan and provide a bond to the Department of Environmental Quality (DEQ) within specific timeframes after commencing commercial operation. The DEQ determines the bond amount based on factors like site characteristics and salvage value. The bill also outlines various exemptions for facilities already bonded elsewhere or meeting certain size and operation criteria, and establishes penalties for non-compliance.
