HB 283 would allow Montana's wildlife commission to issue one male mountain sheep and one male Shiras moose hunting license annually through a lottery or auction, instead of traditional methods. Hunters seeking these licenses would enter the lottery, and any proceeds from sales would fund conservation efforts for these species, with wildlife groups allowed to retain up to 10% of proceeds to cover lottery costs. The bill specifies that all remaining funds must directly benefit mountain sheep and moose management, supplementing existing department budgets. Note: This bill was vetoed by the governor and the legislature failed to override the veto, so it is not currently 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 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 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 222 proposed creating a year-round open wolf hunting season in Montana. This season would have an unlimited quota, meaning there would be no limit on the number of wolves that could be hunted. The hunting season would continue until the statewide wolf population reached 600 or fewer, at which point it could be closed. The bill aimed to amend existing state law to mandate that the Fish, Wildlife & Parks Commission authorize this specific wolf hunting season.
HB 256 proposed creating the Montana Water Development State Special Revenue Account to fund water-related projects and infrastructure. This new account would be established with gifts, legislative transfers, and $100 million transferred from the state's general fund over two years. The earnings from this account would be distributed, with 90% allocated to the water storage state special revenue account for state-owned water storage projects. The remaining 10% would go to the natural resources projects state special revenue account to support water storage pilot projects and dam inspections, ultimately affecting water infrastructure and safety across Montana.
HB 139 aimed to revise laws related to mule deer buck hunting in Montana, directly affecting hunters and the state's Fish, Wildlife & Parks commission. The bill would have restricted the commission's ability to close mule deer buck hunting during the general rifle season in November. Specifically, it would have prohibited closures in more than 20% of hunting districts per season, for more than two years within a six-year period in any district, or prior to November 6 in any district. These new restrictions would not have applied to any district closures already in place before December 1, 2024.
HB 813, known as the "Agricultural Emissions Right to Repair Act," aimed to revise laws concerning the repair and maintenance of agricultural equipment. The bill would have required original equipment manufacturers (OEMs) to provide independent repair providers and equipment owners with documentation, parts, and tools necessary for diagnosing, maintaining, and repairing agricultural equipment *emission systems*. These resources were to be made available on "fair and reasonable terms," and the bill prohibited practices such as parts pairing that could hinder repairs. The goal was to ensure greater access to the resources needed for fixing emissions-related components on agricultural machinery.
HB 290 aimed to regulate products containing Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) within the state. Starting January 1, 2028, it would prohibit the manufacture, sale, or offer for sale of cosmetics, juvenile products, and menstrual products that contain intentionally added PFAS. Manufacturers would be required to provide a certificate of compliance for these products. Additionally, the bill would prohibit the use of class B firefighting foam containing intentionally added PFAS for training purposes from January 1, 2028, and regulate its emergency use at terminals, requiring annual notice and justification to the state fire marshal.
