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 160 requires owners of qualifying wind and solar energy facilities in Montana (solar: 2+ megawatts, wind: 25+ megawatts) to provide a decommissioning bond before construction begins. The bond amount, determined by the Department of Environmental Quality based on the owner's decommissioning plan, ensures funds are available to dismantle facilities and restore land within 24 months after a facility's end of life or abandonment. This applies to new projects and modifies existing requirements for facility owners to submit plans and bonds prior to commercial operation.
SB 406 would require Montana's investor-owned utilities to implement energy conservation programs achieving at least 1% of their average annual electricity sales in savings by 2026. Utilities must conduct biennial assessments to identify cost-effective conservation opportunities (like efficient appliances, lighting, and grid improvements) and submit plans for commission approval. The law mandates that programs be funded through customer rates, with utilities allowed to recover costs and share in rewards for successful conservation investments. It aims to reduce peak electricity demand, improve grid reliability, and defer costly infrastructure investments without specifying outcomes.
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 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.
