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 71: Revise special license requirements allowing second lion license and removing Tendoy sheep reporting

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 813: Provide for the agricultural emissions right to repair act

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 101: Reclassify wolves as furbearers and align existing wolf tagging and furbearer hunting restrictions

HB 101 reclassifies gray wolves as furbearers, integrating them into existing furbearer hunting and trapping regulations. The bill establishes specific wolf hunting licenses for residents and nonresidents, outlining associated fees and tagging requirements for harvested wolves. It introduces new management provisions, allowing for more liberal harvest opportunities such as multiple licenses per individual, the use of bait for trapping, and night hunting on private lands. Additionally, the bill permits landowners to take wolves threatening human safety, livestock, or dogs on their property without a license under specific reporting requirements and a quota.

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 587: Revise mine reclamation laws

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 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 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.
