This bill declares that the Montana Department of Environmental Quality has full authority over air quality, water quality, and emissions standards for existing fossil fuel-fired electric generating units within the state. It designates the department as the sole oversight and permitting authority for coal, natural gas, and oil power plants currently operating in Montana, while asserting that federal agencies lack authority to regulate these facilities without significant economic investment from owners and ratepayers. The legislation includes a contingency clause that would void the bill if the federal Environmental Protection Agency repeals specific rules from May 2024, and it takes effect immediately upon passage and approval.
This bill directs Montana's Department of Environmental Quality to remove all references to numeric nutrient standards from state administrative rules and repeal the 2015 base numeric nutrient standards that were previously adopted. It affects water quality regulators, wastewater treatment facilities, and other entities subject to nutrient discharge regulations by eliminating specific numerical limits for pollutants like nitrogen and phosphorus. The legislation also eliminates the Nutrient Work Group and amends state law to shift toward narrative nutrient standards, which describe water quality goals in descriptive terms rather than specific numerical thresholds. By repealing these standards, the bill aims to reduce regulatory burdens on municipal wastewater systems and align state policy with the 2021 legislative decision to move away from numeric criteria.
This bill allows industrial facilities and other permitted water polluters in Montana to receive credits, known as nutrient pollutant loading offsets, when they reduce nutrient pollution in local watersheds. These credits enable facilities to legally discharge more nutrients or reduce pollution from other sources, provided the overall nutrient load in the watershed decreases. The law sets specific credit values based on where pollution reductions occur, awarding full credits for point source reductions, 80% for upstream nonpoint source reductions, and 50% for downstream nonpoint source reductions. It also directs the state environmental department to establish standardized credit amounts for conservation projects like riparian fencing, wetland development, and septic system removal. The bill requires the department to update existing policies and regulations to implement this nutrient trading system.
This bill exempts the state department from conducting environmental reviews for certain subdivision applications and water or sewer system plans, allowing local governments and independent reviewers to handle these assessments instead. It delegates review authority for small public water and sewer systems to local government divisions that establish satisfactory review programs, with local entities receiving 90% of review fees. The legislation also clarifies that storm drainage review requirements do not apply to single-family residential parcels of 5 acres or larger with no more than 25% impervious surface, and establishes certification procedures for local departments and independent reviewers to ensure competency in conducting these reviews.
This bill allows Montana cities and towns to independently review and approve the design and construction of public water and sewer systems, including modifications to existing infrastructure. To exercise this authority, municipalities must hire or contract with a licensed professional engineer and establish a formal review program. The bill also requires these local review processes to comply with state environmental policies, property takings rules, and water quality standards. This change gives local governments more direct control over infrastructure projects within their jurisdictions while maintaining oversight through existing state regulations.
This bill establishes a feasibility allowance process that allows energy development projects to temporarily exceed water quality standards for high-quality waters under specific conditions. It directly affects energy developers, environmental agencies, and communities near water bodies by creating a formal mechanism to evaluate whether proposed infrastructure projects can proceed without causing significant water quality degradation. The legislation defines key terms such as "energy development project," "high-quality waters," and "associated supporting infrastructure" to clarify what qualifies for the allowance and sets rules for how the Department of Environmental Quality must assess feasibility requests. By amending existing statutes and administrative rules, the bill provides the department with authority to issue permits that permit limited water quality changes while maintaining overall protection standards.
This bill revises Montana's lakeshore protection laws to clarify definitions and strengthen enforcement for unauthorized work near lakes. It directly affects property owners, contractors, and local governments by establishing clearer rules for what constitutes a lake and lakeshore, requiring permits for construction activities, and allowing local authorities to issue stop-work orders. Key provisions include a 90-day timeline for permit decisions, the ability to require surety bonds to cover potential restoration costs, and new penalties that can include fines up to $10,000 for repeat offenders, jail time, and property liens for unpaid restoration costs. The bill also encourages cooperation between multiple governing bodies that share jurisdiction over the same lake.
This bill (LC 3867) aimed to revise state laws governing public funding for wastewater treatment facilities, which would have directly affected local municipalities and public utilities managing these systems. However, the bill was drafted but never advanced beyond the initial drafting phase, as it "died in process" on May 23, 2025. The context provides no details about specific provisions, mechanisms, or policy changes the bill would have implemented. Since the bill was not enacted or debated, no concrete policy changes were made. No further information about its intended scope or effects is available in the provided records.
HB 6 implements the Renewable Resource Grant and Loan Program by appropriating funds to the Department of Natural Resources and Conservation (DNRC). The bill allocates specific amounts for various grant types, including emergency projects, planning, irrigation development, private projects, and nonpoint source pollution reduction. Additionally, it appropriates $5.25 million for prioritized infrastructure grant projects to specific cities, towns, and water districts for improvements to wastewater systems, drinking water infrastructure, and stormwater control. Funds for these prioritized projects are awarded in a specified order until available money is expended.
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.
