The Supreme Court on Wednesday will consider a request to halt implementation of an Environmental Protection Agency rule on cross-state pollution that critics say is unworkable.
The oral arguments are set as congressional Republicans fight the Biden administration’s air quality standards and consider legislation to alter the EPA’s authority.
In Ohio v. EPA, Republican-led states and industry groups urge the Supreme Court to halt implementation of regulations under the so-called “good neighbor” provision. The Clean Air Act requires states to ensure their emissions do not interfere with a downwind state’s efforts to meet National Ambient Air Quality Standards.
