SUPPLEMENTARY INFORMATION:

In the Final Rules section of this Federal Register, EPA is approving the State's redesignation request and State Implementation Plan (SIP) revision, involving the maintenance plan, as a direct final rule without prior proposal because the Agency views the redesignation and SIP revision as noncontroversial and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no adverse comments are received in response to this proposed rule, no further activity is contemplated in relation to this rule. If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period on this action. Any parties interested in commenting on this action should do so at this time.

For additional information see the direct final rule, of the same title, published in the rules section of this Federal Register.
