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 481 prohibits motorboats and personal watercraft on designated Class II waters in Montana. It directly affects recreational users who operate motorized watercraft on these specific waterways, which are likely smaller or sensitive streams or rivers under state classification. The key provision amends Montana law to explicitly ban such motorized use on Class II waters, replacing previous language that only implied restrictions. The bill also requires the commission to adopt rules for managing recreational use on Class I and II waters, including procedures for limiting or restricting activities.
SB 403 would have granted Montana's Fish and Wildlife Commission the authority to set the specific dates and duration for the state's annual muzzleloader heritage hunting season, replacing a previously fixed schedule. This change would directly affect hunters using traditional muzzleloading rifles for deer and elk during this designated season. The bill would have allowed the Commission to adjust the season dates and length based on wildlife management needs, rather than requiring it to follow a fixed timeline (e.g., "second Saturday after regular season for 9 days"). The season itself would have permitted hunting deer or elk with muzzleloaders using specific ammunition and firearm types, as defined by existing regulations.
SB 349 would have transferred authority over air and water quality regulations for existing fossil fuel power plants in Montana from the federal Environmental Protection Agency (EPA) to the state Department of Environmental Quality (DEQ), making DEQ the sole permitting authority for these facilities. It claims federal EPA rules lack authority to restrict plant operations without requiring "significant economic investment" from plant owners and utilities. The bill includes a contingency that would void it if the EPA repeals two specific 2024 rules (89 Fed. Reg. 38508 and 39798). This bill died in committee in May 2025 and never became law.
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.
House Bill 932 revises laws related to funding for conservation efforts, primarily by reallocating a portion of the state's marijuana tax revenue. The bill establishes a new Habitat Legacy Account, which receives 20% of the net balance from the Marijuana State Special Revenue Account after an initial transfer. Funds from this Habitat Legacy Account are then distributed into three other new accounts. These accounts are dedicated to securing wildlife habitat, funding wildlife improvement projects, and supporting the design and construction of big game and wildlife highway crossings to enhance animal movement and safety. The Department of Fish, Wildlife, and Parks is responsible for administering these new accounts.
