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 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.

HB 55 revises the laws governing how public utilities plan for their customers' future energy needs. It requires public utilities to submit detailed resource plans every three years, including evaluations of renewable energy and demand-side management scenarios, and to hold more public meetings before submitting these plans. The bill establishes a special revenue account within the Department of Environmental Quality to fund an independent evaluator, paid for by fees charged to public utilities, who will assist in reviewing these plans. Additionally, the state commission can now engage independent consultants to evaluate utility plans, with these costs being recoverable in rates charged to customers.
