Approval and Promulgation of Implementation Plans; Tennessee: Approval of Revisions to the Knox County Portion of the Tennessee State Implementation Plan

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

SUMMARY: EPA is proposing to approve revisions to the State Implementation Plan (SIP) submitted by the State of Tennessee, through Tennessee Department of Environment and Conservation (TDEC), on August 18, 1999 and July 16, 2001. The revisions pertain to the Knox County portion of the Tennessee SIP and include changes to the Knox County Air Quality Regulations Section 51.0--Standards for Cement Kilns. These standards set nitrogen oxides (NOX) emissions control, compliance demonstration, certification, record keeping, and reporting requirements for Portland cement kilns in the County. The revisions were initially reviewed by TDEC, which found them to be as

stringent as the State's requirements. After review of this submittal, EPA concurs with TDEC's finding. The proposed changes are part of the Knox County strategy to meet the national ambient air quality standards by reducing the emissions of NOX, a precursor of ozone formation. Because of the harmful health effects of ozone, EPA limits the amount of volatile organic compounds and NOXthat can be released into the atmosphere. This action is being taken pursuant to section 110 of the Clean Air Act. In the Final Rules Section of this Federal Register, the EPA is approving the State's SIP revisions 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 significant, material, and 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this rule.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 May 14, 2007.
