SB 340, introduced by Senator D. Zolnikov, would have revised Montana’s environmental law by adding a $240 fee for filing lawsuits challenging agency decisions under the Montana Environmental Protection Act (MEPA). It would have required plaintiffs to cover agency costs for preparing records, limited follow-up lawsuits to new issues only, and prohibited courts from awarding attorney fees or costs to winning plaintiffs. The bill directed the $240 fee to the state’s environmental rehabilitation account, which funds mine reclamation and hazardous waste cleanup. However, the bill died in committee in May 2025 and never became law.
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.
SB 209 limits conservation easements to a maximum term of 40 years (previously allowing perpetual terms), amending Montana law to require renewal for additional periods. It directly affects landowners who use conservation easements, prohibiting restrictions on agricultural activities for lands used for farming within the past decade and banning land conversion to federal control under such easements. Key provisions include revising definitions of "conservation easement" and "open-space land," and ensuring property tax assessments reflect the land's restricted use without lowering valuation. The bill does not change existing permitted easement restrictions (like limiting construction or development) but adds specific protections for agricultural use and landowner control.
HB 71 revises Montana hunting rules by allowing hunters to obtain more than one mountain lion license in a single license year, removing a previous restriction that limited hunters to one lion license per year. It also eliminates mandatory reporting requirements for the Montana Department of Fish, Wildlife, and Parks regarding harvests and tissue sampling from the Tendoy mountain sheep herd. These changes directly affect hunters seeking mountain lion licenses and the wildlife department’s reporting obligations. The bill amends Section 87-2-702 of Montana law to reflect these policy adjustments, focusing on simplifying licensing and reducing administrative reporting burdens.
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.
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.
