Summary

Repeals the EPA's May 7, 2024 final rule that updated hazardous air pollutant standards for coal- and oil-fired electric utility steam generating units and declares that rule has no force or effect and should be treated as if it never took effect. The repeal would remove the regulatory changes made by that EPA rule and restore the prior regulatory status for affected units unless and until the agency issues a different rule.

Key Points

• Nullifies the EPA final rule on hazardous air pollutant standards for coal- and oil-fired electric utility steam generating units published May 7, 2024.
• Declares the specified EPA rule "has no force or effect" and treats it as if it never took effect.
• Removes the new or revised regulatory requirements created by that EPA action for affected power plants.
• Does not itself create replacement standards or direct EPA to adopt an alternative rule.
• Likely reduces immediate compliance obligations for affected facilities but increases regulatory uncertainty about future standards.
• May prompt legal challenges, follow-up rulemaking by EPA, and engagement from state, industry, and public health stakeholders.
• Affects the regulatory status of coal- and oil-fired electric utility steam generating units nationwide.
