The Environmental Protection Agency (EPA) is proposing conditional approval of portions of State Implementation Plan (SIP) revisions submitted by the State of Colorado on May 14, 2018 and May 13, 2020. The revisions are to Colorado Air Quality Control Commission (Commission or AQCC) Regulation Number 7 (Reg. 7), and address Colorado's SIP obligation to require reasonably available control technology (RACT) for sources covered by the 2016 oil & natural gas control techniques guidelines (CTG or CTGs) for Moderate nonattainment areas under the 2008 ozone National Ambient Air Quality Standard (NAAQS). These revisions address the final remaining pieces of the May 14, 2018 and May 13, 2020 submittals that we have not previously acted on. The EPA is taking this action pursuant to the Clean Air Act (CAA).
