Delegation of National Emission Standards for Hazardous Air Pollutants for Source Categories; State of Arizona; Arizona Department of Environmental Quality

Riepilogo

Pursuant to section 112(l) of the 1990 Clean Air Act, EPA granted delegation of specific national emission standards for hazardous air pollutants (NESHAPs) to the Arizona Department of Environmental Quality on March 5, 2001. In the Rules section of this Federal Register, EPA is amending regulations to reflect the current delegation status of NESHAPs in Arizona. EPA is taking direct final action without prior proposal because the Agency views this as a noncontroversial action and anticipates no adverse comments. A detailed rationale for this approval is set forth in the direct final rule. If no adverse comments are received, no further activity is contemplated. If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. The EPA will not institute a second comment period. Any parties interested in commenting should do so at this time.
