EPA is approving revisions to the North Dakota State Implementation Plan (SIP) that the Governor of North Dakota submitted with a letter dated April 6, 2009. The revisions affect North Dakota's air pollution control rules regarding general provisions (including rules regarding shutdowns and malfunctions), ambient air quality standards, emissions of particulate matter, permitting, and fees. In addition, EPA is making administrative corrections to the regulatory text for North Dakota that will be codified in the Code of Federal Regulations; we made errors in the identification of plan table when we approved the North Dakota State Implementation Plan revisions for Interstate Transport of pollution, which the Governor also submitted on April 6, 2009. EPA proposed approval of these rules on May 5, 2011 and received no adverse comments. This action is being taken under section 110 of the Clean Air Act (CAA).
