Start Preamble

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to approve a revision to the Louisiana State Implementation Plan (SIP) submitted on September 22, 2006, enacted at Louisiana Administrative Code, Title 33, Part III, Chapter 5, Section 506(C) (LAC 33:III.506(C)). This revision addresses the requirements of EPA's Clean Air Interstate Rule (CAIR) Sulfur Dioxide (SO2) Trading Program, promulgated on May 12, 2005 and subsequently revised on April 28, 2006. EPA is proposing to determine that the SIP revision fully implements the CAIR SO2 requirements for Louisiana. Therefore, as a consequence of the SIP approval, EPA will also withdraw the CAIR Federal Implementation Plan (CAIR FIP) concerning SO2 emissions for Louisiana. The CAIR FIPs for all States in the CAIR region were promulgated on April 28, 2006 and subsequently revised on December 13, 2006.

CAIR requires States to reduce emissions of SO2 and nitrogen oxides (NOX) that significantly contribute to, and interfere with maintenance of, the national ambient air quality standards for fine particulates and/or ozone in any downwind state. CAIR establishes State budgets for SO2 and NOX and requires States to submit SIP revisions that implement these budgets in States that EPA concluded did contribute to nonattainment in downwind states. States have the flexibility to choose which control measures to adopt to achieve the budgets, including participating in the EPA-administered cap-and-trade programs. In the SIP revision that EPA is proposing to approve, Louisiana would meet CAIR SO2 requirements by participating in the EPA-administered cap-and-trade program addressing SO2 emissions.

The intended effect of this action is to reduce SO2 emissions from the State of Louisiana that are contributing to nonattainment of the PM2.5 National Ambient Air Quality Standard (NAAQS or standard) in downwind states. This action is being taken under section 110 of the Federal Clean Air Act (the Act or CAA).

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 relevant 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 relevant 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 the 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.
