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

[[Page 18427]]

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 NOX that 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receives adverse comments, the direct final rule will be withdrawn and 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.
