## Abstract

The EPA is approving revisions to Colorado's construction permit requirements in Regulation No. 3 and hazardous air pollutant requirements in Regulation No. 8 of the State Air Quality Control Commission (AQCC) regulations, regarding permits to limit potential to emit criteria and hazardous air pollutants (HAPs). These revisions were submitted to EPA on April 26, 1996. Colorado submitted these revisions to create federally enforceable limits on criteria pollutants and HAPs, for both new and existing sources, through the State's construction permit program. EPA is approving the revisions to Regulation No. 3 regarding criteria pollutants as part of Colorado's state implementation plan (SIP) under section 110 of the Clean Air Act (CAA). SIP approval under section 110 of the CAA, however, only extends to the control of HAPs that are criteria pollutants, such as volatile organic compounds or particulate matter, whereas section 112 of the CAA provides the underlying authority for controlling all HAPs listed in section 112(b) of the CAA. Therefore, the EPA is also approving the revisions to Regulation No. 3 and Regulation No. 8 under section 112(l) of the CAA.
