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 2331 requires Arizona's public power entities and public service corporations to consider specific energy criteria when making planning and procurement decisions. The bill defines "clean energy" to include natural gas and nuclear power (if emissions meet pipeline-quality standards), "reliable energy" (requiring consistent power output and grid stability), and "affordable resource energy" (prioritizing stable costs and long-term savings). It mandates that these entities prioritize domestic fuel sources and minimize reliance on foreign materials for critical energy needs. The law directly affects how Arizona's energy providers evaluate and select power sources, emphasizing domestic availability, cost stability, and grid reliability.
