SJ 14: Resolution to release federal wilderness study areas

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 349: Declare authority over existing fossil-fuel fired electric generating units

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 294: Requiring public utilities to report a plan for 100% renewables

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: 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 923: Revise categorical exclusions from nondegradation authorization

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 684: Eliminate deadline for water quality data review

HB 684 eliminates a specific deadline that previously required the Department of Environmental Quality (DEQ) to review data used for water quality assessments. This bill amends Section 75-5-702, MCA, removing the requirement for the DEQ to complete these data reviews within a set timeframe. This change primarily affects the DEQ's operational procedures for monitoring state waters and assessing their quality, as well as individuals and entities who submit water quality data for review.

HB 703: Exempt GHG emissions analysis for appliances, vehicles, engines

HB 703 exempts specific state and local agencies in Montana from analyzing greenhouse gas emissions during certain environmental reviews. The bill states that the state department and local building departments are no longer required to analyze greenhouse gas emissions from covered appliances when adopting or enforcing building codes. It also exempts the state department from analyzing greenhouse gas emissions from new motor vehicles, engines, and nonroad vehicles, and emissions originating outside the state's borders. The bill cites federal preemption laws as the basis for these exemptions from environmental review.

HB 26: Repeal mercury thermostat collection act

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: Exempt Commerce grants and loans from MEPA

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: Revise laws related to lakeshore protection

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.
