E7-16315. Approval and Promulgation of Implementation Plans South Carolina: Revisions to Ambient Air Quality Standards

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to approve the State Implementation Plan (SIP) revisions submitted by the South Carolina Department of Health and Environmental Control (SC DHEC) on November 19, 2004, for the purpose of incorporating EPA's July 18, 1997, revisions to the National Ambient Air Quality Standards and to ensure consistency between state and Federal regulations. The proposed revisions consist of the amendments published in the South Carolina State Register on September 24, 2004, revising Regulation 61-62.5, Standard Number 2, Ambient Air Quality Standards. 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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 September 21, 2007.
