Approval and Promulgation of Air Quality Implementation Plans;

Tennessee; Approval of Revisions to the Knox County Portion

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

SUMMARY: EPA is taking direct final action to approve a revision to the

Knox County portion of the Tennessee State Implementation Plan (SIP) submitted by the State of Tennessee on April 21, 2008. The revision pertains to the Knox County Department of Air Quality Management

(KCDAQM) Regulation, Section 25.0 ``Permits,'' specifically subsection 25.6--Exemptions. This revision removes ``mobile sources'' from the list of exempted air contaminant sources, with respect to operating permits and reserves subsection 25.6.A. This revision is part of KCDAQM strategy to attain and maintain the National Ambient Air Quality

Standards for 8-hour ozone, particulate matter (PM)2.5and

PM10. This revision was certified by the Tennessee

Department of Environment and Conservation to be at least as stringent as the State of Tennessee's existing requirements in Chapter 1200-3- 9-.04 ``Exemptions,'' and is being approved pursuant to section 110 of the Clean Air Act (CAA).

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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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 July 27, 2009.
