Summary

GAO reviewed the Environmental Protection Agency's (EPA) new rule on federal implementation plans to reduce interstate transport of fine particulate matter and ozone. GAO found that (1) the final rule contains EPA's final response to the State of North Carolina's petition submitted under section 126 of the Clean Air Act and makes revisions to the final Clean Air Interstate Rule (CAIR) to clarify certain provisions, correct minor errors, and to take final action on reconsideration of the definition of "electric generating units" as it relates to solid waste incinerators, and (2) EPA complied with the applicable requirements in promulgating the rule.
