This is not a legislative bill but a memorial (SCM 1004) from Arizona's state legislature, not a federal bill. It requests Congress to clarify the EPA's authority to regulate greenhouse gases like CO2 and methane, arguing the EPA lacks explicit statutory power under the Clean Air Act and that current regulations violate the "major questions doctrine" established by the Supreme Court in *West Virginia v. EPA* (2022). The memorial specifically asks Congress to end EPA "regulation overreach" by defining the agency's powers regarding greenhouse gas emissions. It directly affects federal environmental policy by challenging the EPA's current regulatory scope on climate-related emissions.
HB 2456 removes zoning restrictions for small modular nuclear reactors (SMRs) in Arizona when they are colocated with a large industrial energy user that already has all required zoning approvals. It requires SMR developers to provide public notice and hold at least one public comment session in the affected county before construction. This bill directly affects SMR developers seeking to build facilities adjacent to existing industrial energy sites. The law does not create new regulations for SMRs but eliminates local zoning barriers under these specific conditions.
HB 2795 modifies Arizona law to allow small modular reactor (SMR) construction and operation by preventing local governments from restricting these projects under specific conditions. It requires SMR developers to obtain federal early site permits and design certifications, then submit proof of these to the county board of supervisors before local zoning rules can be overridden. This directly affects SMR developers and Arizona counties, ensuring federal approvals supersede local zoning for eligible projects. The law does not alter federal requirements but clarifies that counties cannot block SMR sites once the federal steps are completed and documented.
