EPA is approving changes to North Dakota's State Implementation Plan (SIP). On January 23, 2013, the Governor of North Dakota submitted to EPA revisions to several chapters of the North Dakota SIP. These revisions included the removal of subsections 33-15- 03-04.4 and 33-15-05-01.2.a(l) of the North Dakota Administrative Code (NDAC). In this action, EPA is approving the removal of these subsections from the SIP because it is consistent with Clean Air Act (CAA) requirements. The State's submission corrects certain deficiencies related to the treatment of excess emissions from sources. EPA will address the remaining revisions from North Dakota's January 23, 2013 submission in other actions.
