Start Preamble


Environmental Protection Agency (EPA).


Proposed rule.


EPA is proposing to approve a revision to the Louisiana State Implementation Plan (SIP) concerning a maintenance plan addressing the 1997 8-hour ozone standard for the parish of Pointe Coupee. On February 28, 2007, the State of Louisiana submitted a SIP revision containing a maintenance plan for the 1997 ozone standard for Pointe Coupee Parish. This plan ensures the continued attainment of the 1997 8-hour ozone National Ambient Air Quality Standard (NAAQS) through the year 2014. On March 12, 2008, EPA issued a revised ozone standard. Today's action, however, is being taken to address requirements under the 1997 ozone standard. Requirements for this area under the 2008 standard will be addressed in future actions. This maintenance plan meets statutory and regulatory requirements, and is consistent with EPA's guidance.

In the final rules section of this Federal Register, EPA is approving the State's SIP submittal 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 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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.
