Montana's SJ 14 is a state legislative resolution requesting the federal government release over 660,000 acres of designated wilderness study areas from consideration for inclusion in the National Wilderness Preservation System. It specifically targets seven Montana wilderness study areas (including West Pioneer, Sapphire, and Big Snowies) and 37 Bureau of Land Management wilderness study areas that have remained in legal limbo since the 1977 Montana Wilderness Study Act. The resolution argues these lands are hindering multiple-use management (like timber harvesting and agriculture) and causing federal management uncertainty, and asks for their formal release to allow standard federal land management under the National Forest Management Act. The resolution was tabled in committee and died in process in 2025, so it has not become law.
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.
HB 923 directs the Montana Department of Environmental Quality (DEQ) to amend its administrative rules by January 1, 2026. This amendment will create a new categorical exclusion from nondegradation authorization requirements. This exclusion applies to areas where a county commission demonstrates it has prohibited drinking water wells and ensures absorption trenches are at least 1,000 feet from downstream high-quality surface waters. The bill also appropriates $10,000 to the DEQ to implement these rule changes and provide guidance.
HB 587 revises existing mine reclamation laws. The bill updates the definition of "material damage" and clarifies the hydrologic and geologic information required for mining permits. It grants rulemaking authority to the Department of Environmental Quality and amends specific sections of state law. These changes impact mining operations by adjusting the regulatory framework and definitions used for reclamation activities.
HB 26, titled "Repeal mercury thermostat collection act," eliminates the existing Mercury-Added Thermostat Collection Act. This bill removes state requirements that prohibited the sale and installation of mercury-added thermostats. It also discontinues mandates for manufacturers to operate collection and recycling programs, for wholesalers to provide collection sites, and for related education, outreach, and annual reporting. The repeal of these specific sections of the Montana Code Annotated removes these environmental regulations concerning mercury thermostats.
HB 346 exempts various grant and loan programs from environmental review requirements under the Montana Environmental Policy Act (MEPA). This bill directly affects the Department of Commerce, Board of Housing, and other commissions by removing the need for environmental assessments when authorizing or administering these specific programs. The exemptions apply to programs supporting microbusiness development, historic preservation, workforce training, housing finance, and other economic development initiatives. This aims to streamline the process for providing financial assistance through these identified programs.
SB 168 revises laws regarding lakeshore protection, primarily affecting property owners and contractors with structures in lakeshore protection zones. The bill establishes a 3-year statute of limitations for legal actions against these parties for violating lakeshore regulations, starting from construction completion or permit issuance for clearly visible structures. This limitation does not apply if the structure causes documented harm to the lakeshore, interferes with navigation, or creates a public nuisance. Additionally, the bill exempts minor ongoing maintenance, remodeling, or modifications (changes under $10,000 over five years) from future permitting requirements, unless they involve significant environmental impact or interfere with navigation.
HB 270 revises the Montana Environmental Policy Act (MEPA) by modifying requirements for environmental reviews conducted by state agencies. The bill clarifies that MEPA is procedural and not intended to provide regulatory authority beyond existing statutes. It updates the criteria for analyzing alternatives in environmental impact statements, requiring them to be technologically achievable and economically feasible for similar projects. Furthermore, the bill mandates that agencies consider regulatory impacts on private property rights and analyze alternatives that reduce or eliminate such regulations. For non-state-sponsored projects, alternative recommendations are not binding on the project sponsor.
HJ 35 is a joint resolution from the Montana Legislature urging federal officials to modify current federal land management and wildfire policies. It calls for an aggressive initial attack on wildfires across all federal lands and for federal forest roads to remain open for access and fire suppression. The resolution also recommends that EPA air quality standards include wildfire smoke and that federal "let it burn" policies be reversed, ensuring NEPA processes are followed. Finally, it advocates for increased involvement of state and local governments and stakeholder groups in federal fire management decisions to protect Montana's communities.
