[EPA-R04-OAR-2008-0676-200820(b); FRL-8903-7]


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)2.5 and 
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will be withdrawn and all public comments received will be addressed in 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.
