          - 40 CFR Part 52
          - [EPA-OAR-R04-2008-0512-200815 (b); FRL-8706-3]

# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Proposed rule.

# SUMMARY:

EPA is proposing to approve revisions to the State Implementation Plan submitted by the North Carolina Department of Environment and Natural Resources on behalf of the State of North Carolina on April 16, 2001, April 4, 2003, and December 14, 2004. The purpose of these revisions is to require continuous emissions monitoring systems be used to determine compliance; specify a 24-hour block averaging time for sulfur dioxide emissions; make a correction to a cross-reference; provide options for supplying missing data and for determining heat input; and make several revisions to permit exemptions. This action is being taken pursuant to section 110 of the Clean Air Act.

                        In the Final Rules Section of this                         **Federal Register**                        , EPA is approving the State's SIP revision 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 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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.
