House Bill 477 aimed to phase out the use of expanded polystyrene foam, commonly known as Styrofoam, in food-related businesses. Beginning in 2028, it would have prohibited restaurants and food establishments from serving food or beverages in these containers for on-premises consumption. By 2029, this prohibition would extend to packaging prepared food by restaurants, hotels, and resorts, and by 2030, food packagers would be restricted from using them. Businesses could apply to the Department of Environmental Quality for exemptions if compliance caused undue hardship or if no acceptable alternatives were available, with the department authorized to charge a fee for such applications.

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.

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.

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.

HB 64 repeals Montana's Small Business Compliance Assistance Advisory Council and removes its references from air quality regulations. The bill amends the duties of a small business stationary source representative, eliminating requirements for them to consult with the now-repealed council. This directly affects Montana small businesses subject to air quality regulations, as the council previously provided input on compliance challenges. The change streamlines the representative's role by removing council-related obligations while keeping their core responsibilities for assisting small businesses with regulatory compliance.
