**Approval and Promulgation of Implementation Plans; Tennessee;**  **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 Knox County portion of the Tennessee State Implementation Plan (SIP), submitted by the State of Tennessee Department of Environment and Conservation (TDEC) on August 19, 2009, August 22, 2012, and October 12, 2012. The SIP submittals include changes to Knox County Air Quality Management Regulations concerning Open Burning, Permits and Regulation of Volatile Organic Compounds. TDEC considers Knox County’s SIP revisions to be as or more stringent than the Tennessee SIP requirements. EPA is proposing to approve the Knox County SIP revisions because the State has demonstrated that they are consistent with the Clean Air Act.

In the Final Rules Section of this Federal Register, EPA is approving the State’s implementation plan 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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.
