Q: What is the EPA Utility MACT Rule?
A: The Maximum Achievable Control Technology (MACT) rule requires coal and oil-fired power plants to reduce emissions of mercury, other metallic toxics, acid gases, and organic air toxics.
Q: Why is EPA proposing these regulations now?
A: EPA’s March 16, 2011 Utility MACT rule complies with a Consent Decree of the D.C. Court of Appeals that requires EPA to fulfill the 1990 Clean Air Act regarding hazardous air pollution from power plants. The Clean Air Act required EPA to determine whether such regulation is “appropriate and necessary,” which EPA did in 2000. The Court established deadlines of March 16, 2011 for the proposed rule and November 16, 2011 for the final rule.
