Approval and Promulgation of Air Quality Implementation; North Dakota; Revisions to New Source Review Rules

Riepilogo

EPA is proposing to approve revisions adopted by North Dakota on February 1, 2005 to Chapter 33-15-15 of the North Dakota Administrative Code (Prevention of Significant Deterioration of Air Quality) that incorporate EPA's December 31, 2002 NSR Reforms. North Dakota submitted the request for approval of these rule revisions into the State Implementation Plan (SIP) on February 10, 2005. North Dakota has a federally-approved Prevention of Significant Deterioration (PSD) program for new and modified sources impacting attainment areas in the State. North Dakota is in attainment for all pollutants, and does not have a SIP-approved non-attainment permit program. On December 31, 2002, EPA published revisions to the Federal Prevention of Significant Deterioration (PSD) and non-attainment NSR regulations (67 FR 80186). These revisions are commonly referred to as "NSR Reform" regulations and became effective nationally in areas not covered by a SIP on March 3, 2003. These regulatory revisions include provisions for baseline emissions determinations, actual-to-future- actual methodology, plantwide applicability limits (PALs), clean units, and pollution control projects (PCPs).
