HB 180 revises sanitation laws for subdivisions, focusing on "mixing zones" associated with subsurface wastewater treatment systems. The bill prohibits local boards of health from adopting regulations that would allow these mixing zones, which are areas where treated wastewater mixes with groundwater, to extend onto adjacent properties. This measure restricts the regulatory authority of local health boards and aims to protect adjacent property owners from encroachment by neighboring septic systems. It ensures that the environmental impact of such systems remains within the boundaries of the property where they are installed.
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.
HB 330 creates a new system for issuing special hunting licenses for antelope and swans. Each year, the state commission may offer one antelope and one swan license through a competitive auction or lottery. Wildlife conservation organizations can be authorized to conduct these events, retaining a small portion of the proceeds to cover expenses. All remaining funds generated from these license sales will be used by the department specifically for the conservation and management of antelope and migratory game birds.
HB 58 revises how state funds are distributed for environmental cleanup, specifically targeting abandoned mine sites and hazardous waste areas. The bill mandates a biennial transfer of $500,000 through June 2038 for long-term maintenance and water treatment at the CR Kendall mine reclamation site. It also extends the state's financial contribution for cleanup, operation, and maintenance at the Libby asbestos superfund site until June 2038. These provisions ensure continued funding for critical environmental remediation efforts managed by the Department of Environmental Quality.
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.
HB 189 revises the eligibility requirements for reimbursement from the petroleum tank release cleanup fund. It primarily changes the date for which cleanup expenses can be reimbursed, extending it from April 13, 1989, to January 1, 1984, for certain owners and operators of petroleum storage tanks. This adjustment allows for the reimbursement of older cleanup costs for releases from eligible tanks. The bill also extends rulemaking authority related to these provisions.
SB 315 revises laws related to the Petroleum Tank Release Compensation Board, establishing new procedures for reimbursing owners and operators of Montana petroleum facilities for preventative measures. These measures include the removal of inactive tanks, upgrades to automatic tank gauges, and replacement of older single-walled tanks and piping. Owners or operators can receive up to $2,000 per facility every 1,000 days for approved preventative actions. The bill also modifies procedures for discussing responses to petroleum releases, making meetings discretionary for releases under $100,000.
HB 120 expands Montana's Commercial Property-Assessed Clean Energy (C-PACE) program to include multifamily housing facilities with at least five residential units. This change directly affects property owners and developers of qualifying multifamily buildings (e.g., apartment complexes), allowing them to finance energy efficiency and renewable energy upgrades through property assessments. The bill amends definitions to explicitly include these residential properties under the program, covering improvements like insulation, solar panels, and energy-efficient appliances. It maintains the existing financing mechanism where costs are repaid through property taxes over time, without requiring new debt or upfront payments from property owners. The law took effect immediately upon the governor's signature on April 7, 2025.
HB 146 establishes new hunting license fees for sandhill cranes and swans in Montana. It adds $10 for resident and $50 for nonresident application fees for these species, plus $10 resident/$75 nonresident licenses for cranes and swans (requiring also a $5.50 migratory game bird license). All fees collected for these licenses and applications will fund Montana's wetland conservation efforts through the state special revenue account. The law takes effect March 1, 2026, after being signed by the Governor on April 7, 2025.
