This bill revises Montana's water quality standards by repealing the existing numeric nutrient standards. It directs the Department of Environmental Quality (DEQ) to remove all references to these standards from administrative rules and repeal the specific circular (DEQ-12A) that established them. The bill aims to address the previous standards, which were described as unachievable and burdensome for entities like Montana's municipal wastewater treatment systems. Additionally, it requires the DEQ to update related guidance and policies and eliminates the Nutrient Work Group.

HB 291 limits the ability of Montana's Department of Environmental Quality (DEQ) and local air pollution control programs to set air quality standards stricter than federal requirements. The bill prohibits the DEQ from establishing emission levels or rules more stringent than federal Clean Air Act standards, with exceptions for existing requirements and areas that do not meet national ambient air quality standards. It also revises the process for the DEQ to adopt any rules more stringent than federal guidelines, now only allowing it through emergency rulemaking. Local air pollution control programs are similarly restricted from adopting more stringent rules without specific department approval.

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.

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 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.
