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 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.

HB 31: Revise wind and solar facility decommissioning

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.

HB 55: Revising public utility resource planning laws

HB 55 revises the laws governing how public utilities plan for their customers' future energy needs. It requires public utilities to submit detailed resource plans every three years, including evaluations of renewable energy and demand-side management scenarios, and to hold more public meetings before submitting these plans. The bill establishes a special revenue account within the Department of Environmental Quality to fund an independent evaluator, paid for by fees charged to public utilities, who will assist in reviewing these plans. Additionally, the state commission can now engage independent consultants to evaluate utility plans, with these costs being recoverable in rates charged to customers.

HB 7: Reclamation and development grants

HB 7 implements and funds the reclamation and development grants program, appropriating over $13.9 million from the natural resources projects state special revenue account. The bill allocates funds to the Department of Natural Resources and Conservation (DNRC) for grants beginning July 1, 2025. These grants support planning for reclamation and development projects, pilot water storage initiatives, and specific prioritized projects for political subdivisions and local governments. Grant recipients, which include various counties, cities, and state agencies, must meet conditions such as having an approved project scope, securing matching funds, and complying with auditing requirements.

HB 736: Provide nutrient pollutant loading offsets

HB 736 establishes a system for nutrient pollutant loading offsets for facilities holding water quality discharge permits. It allows these permitted dischargers to meet their nutrient discharge limits by reducing nutrient pollution from other sources within the same watershed, including both direct discharge points and diffuse sources. The bill specifies varying offset percentages based on the type and location of the pollution reduction. It directs the state's environmental department to establish statewide offset values for various nonpoint pollution reduction projects, such as riparian fencing or wetlands development, and to amend existing policies to implement these provisions.

HB 855: Establish FWP wildlife highway crossings and accommodation account

House Bill 855 establishes a dedicated funding mechanism for projects aimed at reducing wildlife-vehicle collisions across Montana. It authorizes the Fish and Wildlife Commission to create a specialty license plate, with a $20 donation from its sale and renewal deposited into a new "Big Game and Wildlife Highway Crossings and Accommodations Account." Funds in this account, which also accepts gifts and grants, are statutorily appropriated to the Department of Fish, Wildlife, and Parks. These funds will be used for the design, construction, maintenance, and study of wildlife crossings and related accommodations on state roadways, improving safety for both drivers and wildlife.

SB 257: Generally revise Smith River permit laws

Senate Bill 257 revises the permit laws for the Smith River waterway. It increases the cost for nonresidents to purchase a bonus point for the Smith River permit lottery from $50 to $125. This change directly affects nonresidents applying for permits to float and camp on the Smith River. The additional revenue generated from these bonus points will be deposited into the Smith River corridor enhancement account, which funds projects to protect and improve the river's natural beauty, recreational values, fisheries, and wildlife habitat.

HB 580: Clarify water right abandonment

HB 580 clarifies Montana's water right abandonment laws, directly affecting individuals and entities holding water rights. The bill specifies that reducing or ceasing the use of a water right during a drought does not automatically signify an intent to abandon that right. This protection applies if the area is experiencing a moderate (D1) or worse drought, or if the nonuse aligns with an official drought plan. The legislation aims to prevent water rights from being lost solely due to conservation efforts during dry periods.
