The Environmental Protection Agency (EPA) is approving a state implementation plan (SIP) revision from the State of Hawaii addressing requirements in the Clean Air Act (CAA or ``Act'') regarding interstate transport for the 2015 ozone national ambient air quality standards (NAAQS). Hawaii submitted a SIP revision on November 12, 2019, addressing the CAA provision prohibiting any source or other type of emissions activity in one state from emitting any air pollutant in amounts that will contribute significantly to nonattainment or interfere with maintenance of the NAAQS in any other state (the ``good neighbor'' provision). The EPA is finalizing approval of Hawaii's good neighbor SIP revision for the 2015 ozone NAAQS.
