SCM 1004 Arizona Senate · 57th Legislature - Second Regular Session

clean air act; EPA powers

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.
