Air Plan Revisions; Arizona; Arizona Department of Environmental Quality; Stationary Source Permits
The Environmental Protection Agency (EPA) is proposing to approve two revisions to the Arizona Department of Environmental Quality (ADEQ) portion of the Arizona State Implementation Plan (SIP). In this action, we are proposing to approve revisions submitted by the ADEQ governing the issuance of permits for stationary sources in accordance with changes that the EPA has made to its New Source Review (NSR) program regulations under the Clean Air Act (CAA or ``the Act''). We are also proposing to determine that with these revisions, the ADEQ's NSR program satisfies the requirements for the preconstruction review and permitting of major sources and major modifications under part D of title I of the Act for areas designated nonattainment with the 2015 ozone National Ambient Air Quality Standards (NAAQS) with a Marginal classification, for areas and sources within the ADEQ's permitting jurisdiction. We are taking comments on this proposal and plan to follow with a final action.
Air Plan Disapproval; Kansas; Regional Haze
The Environmental Protection Agency (EPA) is proposing to disapprove a revision to Kansas's State Implementation Plan (SIP) submitted on July 28, 2021, to satisfy applicable requirements under the Clean Air Act (CAA) and EPA's Regional Haze Rule (RHR) for the program's second planning period. As required by section 169A of the Clean Air Act, the federal Regional Haze Rule calls for state and federal agencies to work together to improve visibility, including Regional Haze, in 156 national parks and wilderness areas. The rule requires the states, in coordination with the EPA, the National Park Service (NPS), U.S. Fish and Wildlife Service (FWS), the U.S. Forest Service (FS), and other interested parties, to develop and implement air quality protection plans in which states revise their long-term strategies (LTS) for making reasonable progress towards the national goal of preventing any future, and remedying any existing, anthropogenic impairment of visibility in these mandatory Class I Federal Areas. Disapproval does not start a mandatory sanctions clock.
