Clean Air Act Approval and Promulgation of Air Quality Implementation Plan Revision for North Dakota; Revisions to the Air Pollution Control Rules; Delegation of Authority for New Source Performance Standards and National Emission Standards for Hazardous Air Pollutants

EPA approves revisions to the State Implementation Plan (SIP) submitted by the Governor of North Dakota with a letter dated June 21, 2001. The revisions affect air pollution control rules regarding general provisions, emissions of particulate matter and fugitives, exclusions from Title V permit to operate requirements, and prevention of significant deterioration. EPA will handle separately direct delegation requests for emission standards for hazardous air pollutants for source categories and the State's Acid Rain Program. In addition, EPA is providing notice that on January 3, 2002, North Dakota was delegated authority to implement and enforce certain New Source Performance Standards (NSPS), as of August 1, 2000. Finally, given that on July 7, 1995 EPA delegated authority to North Dakota to implement and enforce the Clean Air Act section 112 requirements, including, among other things, the National Emission Standards for Hazardous Air Pollutants (NESHAPs), EPA is now removing the State's part 61 regulations from the federally-approved SIP.
