Abstract
The Environmental Protection Agency (EPA) is taking final action to approve State Implementation Plan (SIP) revisions submitted by the State of Colorado on February 25, 2015, and May 24, 2017. These SIP revisions are necessary for Colorado to address current federal prevention of significant deterioration (PSD) and nonattainment new source review (NSR) regulations. In this rulemaking, we are taking final action on all portions of the February 25, 2015, and May 24, 2017 submittals, except for those portions of the submittal which have been previously acted on or do not belong in the SIP. The intended effect of this action is to bring Colorado's PSD and nonattainment NSR permitting programs in line with federal requirements. This action is being taken under section 110 of the Clean Air Act (CAA).
