Approval and Promulgation of Implementation Plans; North 
Carolina: Approval of Rocky Mount Supplemental Motor Vehicle Emissions 
Budget Update

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA is proposing to approve a revision to the North Carolina 
State Implementation Plan (SIP), submitted to EPA on February 7, 2011, 
by the State of North Carolina, through the North Carolina Department 
of Environment and Natural Resources, Division of Air Quality. North 
Carolina's February 7, 2011, submission supplements the original 
redesignation request and maintenance plan for Rocky Mount 1997 8-hour 
ozone area submitted on June 19, 2006, and approved by EPA on November 
6, 2006. The Rocky Mount 1997 8-hour ozone area is comprised of 
Edgecombe and Nash Counties in North Carolina. The February 7, 2011, 
revision proposes to increase the safety margin allocated to motor 
vehicle emissions budgets to account for changes in the emissions model 
and vehicle miles traveled projection model. EPA is proposing approval 
of this SIP revision pursuant to section 110 of the Clean Air Act. 
North Carolina's SIP revision meets all the statutory and regulatory 
requirements, and is consistent with EPA's guidance.

SUPPLEMENTARY INFORMATION: On March 12, 2008, EPA issued a revised 
ozone National Ambient Air Quality Standards (NAAQS). See 73 FR 16436. 
The current action, however, is being taken to address requirements 
under the 1997 8-hour ozone NAAQS. Requirements for the Rocky Mount 
Area under the 2008 NAAQS will be addressed in the future.
    For additional information regarding today's action see the direct 
final rule which is published in the Rules Section of this Federal 
Register. Through that direct final rule, EPA is approving the State's 
implementation plan revision 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comments, the direct final rule will be withdrawn and all public 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.
