SUPPLEMENTARY INFORMATION:

In the Final Rules Section of this Federal Register, EPA is approving the portion of Alabama's May 7, 2012, SIP revision addressing the State's PSD program as a direct final rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule and incorporated herein by reference. If no adverse comments are received in response to this rule, no further activity is contemplated. If EPA receives adverse comments, the direct final rule will be withdrawn and all adverse comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period on this document. Any parties interested in commenting on this document should do so at this time.
