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.

House Bill 696 establishes a framework for the legislative approval of spent nuclear fuel reprocessing facilities within Montana. It authorizes such facilities if they reprocess fuel from in-state or out-of-state sources, receive a state recommendation from the Department of Environmental Quality, and obtain a federal license from the Nuclear Regulatory Commission. The bill also amends existing law, requiring companies applying to federal energy or nuclear regulatory commissions to notify the state's Department of Environmental Quality and pay a fee to support the department's review and participation in federal proceedings.
