EPA proposed to approve portions of a state implementation plan (SIP) revision submitted on September 30, 2019 by the Pennsylvania Department of Environmental Protection (PADEP) on behalf of the Allegheny County Health Department (ACHD). The SIP submittal (also referred to as “the Allegheny County PM2.5 Plan”) addresses Clean Air Act (CAA or “the Act”) requirements for the 2012 annual fine particulate matter (PM2.5) national ambient air quality standards (NAAQS or “standards”) in the Allegheny County Moderate PM2.5 nonattainment area (“Allegheny County area”). EPA's June 12, 2020 document proposed to fully approve all elements of the plan except for those addressing contingency measure requirements and motor vehicle emissions budgets, which EPA proposed to conditionally approve.

EPA is reopening the comment period based on a request by Clean Air Council for a 30-day extension of the comment period. Clean Air Council's request, which is in the docket [1] for this matter, seeks an extension of the comment period until August 13, 2020. Their justification for such an extension included the complexity of the plan and EPA's proposed action, substantial changes to the plan made by ACHD following public comment at the local level, and the fact that EPA's proposed rule's July 13, 2020 close of comment period occurs at a similar time as those of several other state and Federal actions related to air quality in the area, for which comments are due on or around the same time. After reviewing these arguments, EPA has decided to reopen the comment period to August 13, 2020. All comments received on or before August 13, 2020 will be entered into the public record and considered by EPA before taking final action on the proposed rule. Comments submitted between the close of the original comment period and the re-opening of this comment period will be accepted and considered.
