## Abstract

EPA is partially approving and partially disapproving State Implementation Plan (SIP) revisions submitted by the State of Colorado on June 20, 2003 and April 12, 2004. This final rule will approve those portions of the revisions to Colorado's Regulation 3 that place restrictions on increment consumption, add innovative control technology as an alternative to BACT requirements and make other changes as described in more detail below. EPA will act separately on the portions of the June 20, 2003 and April 12, 2004 submittals that revise Regulation 3, Part A, Section II, Air Pollutant Emission Notice (APEN) Requirements. Today's action on the Colorado Regulation 3 revisions will make federally enforceable the revised portions of Colorado's Regulation 3 that EPA is approving. This action is being taken under section 110 of the Clean Air Act.
