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 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 717 revises the process for transferring mining operation permits to successor operators, especially when an original operator has a forfeited bond and fails to complete reclamation. It grants the state's Department the power of eminent domain to acquire surface, mineral, or other property interests within a mining permit boundary under specific conditions. This power can be exercised if the department finds it is in the public interest for taxpayers and environmental protection, and a successor operator is available to take over the permit and complete reclamation. The bill also outlines how compensation is determined in these eminent domain cases, considering factors like reclamation costs and existing liabilities.
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.
HJ 34 is a Joint Resolution from the Montana Legislature expressing strong support for Montana's beef producers, recognizing their vital role in the state's economy and culture. It calls on state and federal governments to prioritize policies that ensure fair market conditions, reduce regulatory burdens, and facilitate better trade relationships for Montana beef. The resolution encourages sustainable beef production practices and opposes federal or state proposals, such as those associated with the Green New Deal, that would impose excessive regulations or taxes on the industry. Additionally, it strongly opposes the promotion, production, and sale of lab-grown "meat" as a substitute for natural beef.
SB 221 revises the Montana Environmental Policy Act (MEPA) by establishing new requirements for greenhouse gas (GHG) assessments during state agency environmental reviews. Under this bill, state agencies are mandated to conduct GHG assessments for proposed actions classified as "fossil fuel activities." For other proposed actions, agencies may conduct a GHG assessment if deemed necessary for MEPA compliance. The bill clarifies that these assessments are for informational purposes, and state agencies cannot regulate greenhouse gas emissions or deny permits based solely on these GHG assessments under MEPA. This affects Montana state agencies conducting environmental reviews and entities proposing fossil fuel-related projects.
Senate Bill 365 revises the capacity requirements for siltation structures at strip and underground mines in Montana. The bill amends Section 82-4-231, MCA, which outlines the process for mine operators to submit and obtain approval for reclamation plans. It grants rulemaking authority to the relevant department to establish specific requirements for these structures. The changes aim to ensure effective water control measures are included in reclamation plans to prevent damages from soil erosion and water pollution.
SB 190 allows individuals or entities applying for new water use permits or changes to existing water rights to streamline their application process. This is achieved by enabling existing water right holders to voluntarily provide written consent. If consent is given, the applicant is no longer required to prove that their proposed water use will not negatively affect the specific consenting water rights. This change aims to simplify the permit approval process under certain conditions.
