The Environmental Protection Agency (EPA) proposes to approve Colorado's regional haze progress report, submitted as a revision to its State Implementation Plan (SIP) by the Colorado Department of Public Health and Environment (CDPHE). Colorado's SIP revision addresses requirements of the Clean Air Act (CAA) and the EPA's rules that require states to submit periodic reports describing progress toward Reasonable Progress Goals (RPGs) established for regional haze and a determination of the adequacy of the state's existing plan addressing regional haze. Colorado's progress report explains that Colorado has implemented the measures in the regional haze plan due to be in place by the date of the progress report and that visibility in mandatory federal Class I areas affected by emissions from Colorado sources is improving. The EPA is proposing approval of Colorado's determination that the State's regional haze plan is adequate to meet RPGs for the first implementation period, which extended through 2018 and requires no substantive revision at this time.
