ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R04-OAR-2006-0577-200620(b); FRL-8265-3]


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 Tennessee State 
Implementation Plan (SIP) submitted by the State of Tennessee, through 
Tennessee Department of Environment and Conservation, on January 20, 
2006. The revisions pertain to the Knox County portion of the Tennessee 
SIP and include changes to the Knox County Air Quality Regulations 
Section 46.0--``Regulation of Volatile Organic Compounds.'' The changes 
were made in response to changes made by EPA to corresponding federal 
law. The change involves the addition of four compounds to the list of 
compounds excluded from the definition of volatile organic compounds on 
the basis that they make a negligible contribution to ozone formation. 
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the direct final rule will be withdrawn and all public comments 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 
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 February 5, 2007.
