The Environmental Protection Agency (EPA) is proposing to approve the Massachusetts regional haze progress report submitted as a State Implementation Plan (SIP) revision on February 9, 2018. This revision addresses the requirements of the Clean Air Act and its implementing regulations that states submit periodic reports describing progress toward reasonable progress goals established for regional haze and a determination of adequacy of the state's existing regional haze SIP. Massachusetts' progress report notes that Massachusetts has implemented the measures in the regional haze SIP due to be in place by the date of the progress report and that visibility in the federal Class I areas affected by emissions from Massachusetts is improving and has already met the applicable reasonable progress goals for 2018. The EPA is proposing approval of Massachusetts' determination that the Commonwealth's regional haze SIP is adequate to meet these reasonable progress goals for the first implementation period, which extends through 2018, and requires no substantive revision at this time.
