## Abstract

EPA is approving a revision to the North Dakota State Implementation Plan (SIP) relating to regulation of Greenhouse Gases (GHGs) and fine particulate matter (PM<INF>2.5</INF>) under North Dakota's Prevention of Significant Deterioration (PSD) program. This revision was submitted by the North Dakota Department of Health Division of Air Quality (ND DOH DAQ) to EPA on April 18, 2011. It is intended to align North Dakota's regulations with the "PSD and Title V Greenhouse Gas Tailoring Final Rule" and the final rule for "Implementation of the New Source Review (NSR) Program for PM<INF>2.5</INF>." EPA is approving the revision because the Agency has determined that the SIP revision, already adopted by North Dakota as a final effective rule, is in accordance with the Clean Air Act (CAA or Act) and EPA regulations regarding PSD permitting for GHGs and PM<INF>2.5</INF>.
