HB 658 would have limited local health boards' authority to create sanitation rules stricter than state standards, affecting communities that previously could enforce tougher local requirements. It specifically protected existing subsurface wastewater systems (like septic systems) from being subject to new local rule changes. The bill amended Montana law (sections 50-2-116 and 50-2-130) to remove local boards' ability to adopt more stringent sanitation regulations and to ensure current systems remain exempt from future rule updates. This change would have shifted regulatory authority toward state standards for wastewater and sanitation compliance.
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 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 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 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.
House Bill 411 (HB 411) exempts agricultural property from local property tax levies that are used to fund open space initiatives. This means that owners of land classified as agricultural will no longer be required to pay the portion of their property taxes designated for open space purposes. The bill also allows counties to reduce any open space payments made to agricultural properties that are now exempt from these levies. This change applies retroactively to property tax years beginning on or after January 1, 2025.
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.
SB 262 exempts certain water and sewer system plans, along with specific subdivision applications, from environmental review requirements. The bill removes the obligation for the state department to conduct environmental reviews for water or sewer system plans. Additionally, it removes the requirement for local governments and independent reviewers to comply with the Montana Environmental Policy Act when reviewing small public water and sewer systems or subdivisions connecting to existing municipal systems. This change aims to streamline the approval process for these types of projects.
