Environmental Protection Agency (EPA).


Proposed rule.


EPA is proposing to approve revisions to the Louisiana State Implementation Plan (SIP) concerning the 8-hour ozone maintenance plans for the parishes of Lafayette and Lafourche. On October 13, 2006, and December 19, 2006, the State of Louisiana submitted maintenance plans for Lafayette and Lafourche Parishes, respectively, which ensure continued attainment of the 8-hour ozone National Ambient Air Quality Standard (NAAQS) through the year 2014. These maintenance plans meet the statutory and regulatory requirements, and are consistent with EPA's guidance. EPA is approving the revisions pursuant to section 110 of the Federal Clean Air Act (CAA).


Written comments must be received on or before April 23, 2008.

In the final rules section of this Federal Register, EPA is approving the State's SIP submittal 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. If no relevant adverse comments are received in response to this action, 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period. Any parties interested in commenting on this action should do so at this time. Please note that if EPA receives adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, EPA may adopt as final those provisions of the rule that are not the subject of an adverse comment.

For additional information, see the direct final rule, which is located in the rules section of this Federal Register.
