# SUPPLEMENTARY INFORMATION:

EPA proposed to approve a state implementation plan (SIP) revision submitted on March 10, 2020 by the Pennsylvania Department of Environmental Protection (PADEP). The SIP submittal (also referred to as “1997 8-hour Ozone National Ambient Air Quality Standard Second Maintenance Plan for the Youngstown-Warren-Sharon Area”) addresses Clean Air Act (CAA) requirements for the 1997 8-hour ozone national ambient air quality standard (NAAQS) in the Youngstown-Warren-Sharon Area. EPA's October 30, 2020 notice proposed to approve the second maintenance plan for the Pennsylvania portion of the Youngstown-Warren-Sharon Area as a revision to the Pennsylvania SIP.

EPA is reopening the comment period based on an anonymous request to reopen the comment period. The commenter states they were unable to obtain information about EPA's proposed rulemaking via email or phone from the EPA contact listed in the October 30, 2020 notice. After reviewing this request, EPA has determined that the listed EPA contact was not available via email or phone during approximately half of the 30-day comment period. Therefore, EPA has decided to reopen the comment period for an additional 15 days to March 16, 2021. All comments received on or before March 16, 2021 will be entered into the public record and considered by EPA before taking final action on the proposed rulemaking. Comments submitted between the close of the original comment period and the re-opening of this comment period will be accepted and considered.

Dated: February 18, 2021.

Acting Regional Administrator, Region III.
