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.
