SB 537: Generally revise marijuana tax laws

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: Generally revise water supply requirements for coal-fired generating units

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: Revise penalties for violations under 310 permit process

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: Prohibit motorboats and motorized watercraft on Class 2 waters

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: Grant the fish and wildlife commission authority to set muzzleloader season

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 473: Prohibit weather modification.

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.

HB 658: Revise local board of health sanitation powers and rules

HB 658 would have limited local health boards' authority to create sanitation rules stricter than state standards, affecting communities that previously could enforce tougher local requirements. It specifically protected existing subsurface wastewater systems (like septic systems) from being subject to new local rule changes. The bill amended Montana law (sections 50-2-116 and 50-2-130) to remove local boards' ability to adopt more stringent sanitation regulations and to ensure current systems remain exempt from future rule updates. This change would have shifted regulatory authority toward state standards for wastewater and sanitation compliance.

HB 57: Designate quail as upland game bird

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: Limits to Fox Hills-Hell Creek aquifer withdrawals

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 932: Generally revise conservation financing laws

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.
