[EPA-R04-OAR-2012-0961; FRL-9782-7]

Approval and Promulgation of Air Quality Implementation Plans; 
Charlotte, Raleigh/Durham and Winston-Salem Carbon Monoxide Limited 
Maintenance Plan

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve a limited maintenance plan update 
submitted by the State of North Carolina, through the North Carolina 
Department of Environment and Natural Resources, on August 2, 2012. The 
limited maintenance plan update is for the Charlotte, Raleigh/Durham 
and Winston-Salem carbon monoxide (CO) maintenance areas. Specifically, 
the State submitted a limited maintenance plan update for CO, showing 
continued attainment of the 8-hour CO National Ambient Air Quality 
Standard for the Charlotte, Raleigh/Durham and Winston-Salem Areas. The 
8-hour CO NAAQS is 9 parts per million. EPA is proposing to approve the 
limited maintenance plan update because the State has demonstrated that 
it is consistent with the Clean Air Act and EPA's policy for limited 
maintenance plans.
