Approval and Promulgation of Implementation Plans North Carolina: Prevention of Significant Deterioration and Nonattainment New Source Review Rules
Document Number: E8-20874
Type: Proposed Rule
Date: 2008-09-09
Agency: Environmental Protection Agency
EPA is proposing to approve revisions to the North Carolina State Implementation Plan (SIP) submitted by the State of North Carolina in three submittals dated November 30, 2005, March 16, 2007, and June 20, 2008. The proposed revisions modify North Carolina's Prevention of Significant Deterioration (PSD) and Nonattainment New Source Review (NNSR) permitting regulations in the SIP to address changes to the federal New Source Review (NSR) regulations, which were promulgated by EPA on December 31, 2002, and reconsidered with minor changes on November 7, 2003 (collectively, these two final actions are referred to as the ``2002 NSR Reform Rules''). In addition, the proposed revisions address an update to the NSR regulations promulgated by EPA on November 29, 2005 (``Ozone Implementation NSR update'') relating to the implementation of the 1997 8-hour ozone National Ambient Air Quality Standards (NAAQS). The proposed revisions include provisions for baseline emissions calculations, an actual-to-projected- actual methodology for calculating emissions changes, options for plantwide applicability limits (PALs), recordkeeping and reporting requirements, and provisions recognizing nitrogen oxides (NOX) as a precursor to ozone. The June 20, 2008, SIP submittal also contains proposed revisions that are not related to EPA's 2002 NSR Reform Rules. EPA will propose action on those revisions in a separate Federal Register notice.
