On March 23, 1995, the State of North Carolina, through the North Carolina Department of Environment, Health and Natural Resources, submitted revisions to the North Carolina State Implementation Plan (SIP). EPA is approving these revisions to rules 15A NCAC 2D .0501 Compliance With Emission Control Standards, .0516 Sulfur Dioxide Emissions From Combustion Sources, and .0530 Prevention Of Significant Deterioration. The intended effect of this revision is to clarify certain provisions and ensure consistency with requirements of the Clean Air Act.
