          - 40 CFR Part 52 
          - [EPA-R06-OAR-2007-0659; FRL-8727-1] 

# AGENCY:

Environmental Protection Agency (EPA). 

# ACTION:

Proposed rule. 

# SUMMARY:

EPA is proposing to approve revisions to the Louisiana State Implementation Plan (SIP) concerning maintenance plans addressing the 1997 8-hour ozone standard for the parishes of Calcasieu and St. James. On July 20, 2007 and August 24, 2007, the State of Louisiana submitted separate SIP revisions containing maintenance plans for the 1997 ozone standard for Calcasieu and St. James Parishes, respectively. These plans ensure the continued attainment of the 1997 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). 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 the areas under the 2008 standard will be addressed in future actions.

# SUPPLEMENTARY INFORMATION:

                    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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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**                    .
