E7-19648. Approval of Implementation Plans; South Carolina: Clean Air Interstate Rule

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to approve revisions to the South Carolina State Implementation Plan (SIP) submitted on August 14, 2007. These revisions will incorporate provisions related to the implementation of EPA's Clean Air Interstate Rule (CAIR), promulgated on May 12, 2005 and subsequently revised on April 28, 2006 and December 13, 2006, and the CAIR Federal Implementation Plans (FIPs) concerning sulfur dioxide (SO₂), nitrogen oxides (NO_X) annual, and NO_X ozone season emissions for the State of South Carolina, promulgated on April 28, 2006 and subsequently revised December 13, 2006. EPA is not proposing to make any changes to the CAIR FIPs, but is amending, to the extent EPA approves South Carolina's SIP revisions, the appropriate appendices in the CAIR FIP trading rules simply to note that approval.

On September 19, 2007, South Carolina requested that EPA only act on a portion of the August 14, 2007, submittal as an abbreviated SIP. Consequently, EPA is proposing to approve the abbreviated SIP revisions that address the methodology to be used to allocate annual and ozone season NO_X allowances under the CAIR FIPs as well as opt-in provisions for the SO₂, NO_X annual, and NO_X ozone season trading programs. South Carolina also requested that EPA approve compliance supplement pool provisions for the NO_X annual trading program.

In the Final Rules Section of this Federal Register, EPA is approving the State's SIP revision 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 adverse comments are received in response to this rule, 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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 on this document. Any parties interested in commenting on this document should do so at this time.

DATES:

Written comments must be received on or before November 8, 2007.
