SB 221: Generally revise the Montana environmental policy act

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.

HJ 44: Interim study of endocrine-disrupting chemicals and water quality

This joint resolution requests an interim study on endocrine-disrupting chemicals (EDCs) and their impact on water quality in Montana. The study, to be conducted by a legislative committee or staff, will review existing state and federal water quality laws and analyze research on the health effects of EDCs. It also aims to determine the prevalence of these chemicals in Montana. The study will offer recommendations for future legislative or regulatory changes, with final results reported to the 70th Legislature by September 15, 2026.

HB 736: Provide nutrient pollutant loading offsets

HB 736 establishes a system for nutrient pollutant loading offsets for facilities holding water quality discharge permits. It allows these permitted dischargers to meet their nutrient discharge limits by reducing nutrient pollution from other sources within the same watershed, including both direct discharge points and diffuse sources. The bill specifies varying offset percentages based on the type and location of the pollution reduction. It directs the state's environmental department to establish statewide offset values for various nonpoint pollution reduction projects, such as riparian fencing or wetlands development, and to amend existing policies to implement these provisions.

HB 660: Require rules to limit GHG emissions

HB 660, titled "Require rules to limit GHG emissions," would have mandated the Montana Department of Environmental Quality (DEQ) to develop specific rules for limiting greenhouse gas emissions. This bill sought to amend existing state law (Section 75-2-112, MCA) by requiring the DEQ to create regulations to protect public health, safety, welfare, and the environment from these emissions. The legislation directly affects the DEQ by expanding its regulatory responsibilities to include greenhouse gases.

HB 26: Repeal mercury thermostat collection act

HB 26, titled "Repeal mercury thermostat collection act," eliminates the existing Mercury-Added Thermostat Collection Act. This bill removes state requirements that prohibited the sale and installation of mercury-added thermostats. It also discontinues mandates for manufacturers to operate collection and recycling programs, for wholesalers to provide collection sites, and for related education, outreach, and annual reporting. The repeal of these specific sections of the Montana Code Annotated removes these environmental regulations concerning mercury thermostats.

HB 270: Revise remedies to MEPA

HB 270 revises the Montana Environmental Policy Act (MEPA) by modifying requirements for environmental reviews conducted by state agencies. The bill clarifies that MEPA is procedural and not intended to provide regulatory authority beyond existing statutes. It updates the criteria for analyzing alternatives in environmental impact statements, requiring them to be technologically achievable and economically feasible for similar projects. Furthermore, the bill mandates that agencies consider regulatory impacts on private property rights and analyze alternatives that reduce or eliminate such regulations. For non-state-sponsored projects, alternative recommendations are not binding on the project sponsor.

HB 477: Phase out polystyrene single use food containers (with exceptions)

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.

HB 466: Provide categorical exclusions from MEPA

House Bill 466 amends the Montana Environmental Policy Act (MEPA) by formally defining and allowing state agencies to identify "categorical exclusions." These exclusions are actions determined to have no significant impact on the human environment and are therefore exempt from requiring an environmental analysis or impact statement. The bill also provides specific exemptions from MEPA review for activities such as building construction by the Department of Administration and historic preservation grants by the Department of Commerce. State agencies are required to track and report their use of these categorical exclusions.

SB 304: Revise Montana lakeshore laws

SB 304 revises Montana's Lakeshore Protection Act to strengthen oversight of development near lakes. It directly affects landowners, developers, and contractors working within 20 feet of a lake's mean high-water elevation. Key provisions include requiring stop-work orders for unauthorized construction, mandating financial guarantees (surety bonds) for permits, updating penalties for violations (up to $10,000 fines or 180-day work pauses for repeat offenses), and allowing local governments to place liens on property to cover cleanup costs and fines. The bill also clarifies definitions, such as requiring lakes to be at least 160 acres and navigable by small boats, to determine which water bodies are protected.

HB 630: Require legislative approval of greenhouse gas rules

HB 630 requires that certain rules established by state departments, commissions, boards, or local authorities are not effective unless approved by the legislature. Specifically, any rules related to the regulation of greenhouse gas emissions or the calculation and application of the social cost of carbon must receive legislative approval at the next legislative session. This mechanism affects agencies that issue such environmental regulations, including those pertaining to the operation of motor vehicles. The bill ensures that the legislature has final say over these specific types of administrative rules.
