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.

SB 55 is a procedural bill that states Montana's legislative intent to support coordinated collection and sharing of streamflow data. It recognizes that timely streamflow information - gathered by state, federal, tribal, and local entities - is essential for managing water under existing laws, including the Montana Water Use Act and drought planning. The bill does not create new programs or funding but affirms the legislature's position that better data coordination benefits water managers, municipalities, and agricultural users in addressing seasonal and climate-related water supply challenges.

SB 61 updates Montana's water policy to require accurate, real-time streamflow measurement for determining water availability. It affects water rights holders and state water managers by ensuring new water uses can only be approved when legally and physically available, protecting existing rights. The bill integrates these measurement standards into Montana's existing water law framework under Title 85. This policy change aims to improve the accuracy of water distribution decisions.

This Montana House resolution (HR 2) expresses legislative support for expanding critical minerals development within the state. It urges state, federal, tribal, and local entities to advance exploration, processing, and recycling of minerals like rare earth elements, platinum group metals, and others found in Montana's geology. The resolution highlights Montana's existing mining infrastructure and aims to strengthen domestic supply chains for technologies, energy, and defense - reducing reliance on foreign sources like China. As a symbolic resolution (not binding law), it directs Montana's delegation to advocate for these projects but does not create new regulations or funding.
