## Abstract

The Environmental Protection Agency (EPA) is approving Hawaii's Regional Haze 5-Year Progress Report ("Progress Report" or "Report"), submitted on October 20, 2017, as a revision to its state implementation plan (SIP). This SIP revision addresses requirements of the Clean Air Act (CAA or "Act") and the EPA's rules that require states to submit periodic reports describing the progress toward reasonable progress goals (RPGs) established for regional haze and a determination of adequacy of the state's existing regional haze plan. The EPA is approving the Report on the basis that it addresses the progress report and adequacy determination requirements for the first implementation period for regional haze.
