The Environmental Protection Agency (EPA) is extending the comment period for a proposed rule published on June 1, 2017. In the June 1, 2017 proposed rule, EPA proposed to approve portions of the State of Delaware's December 14, 2015 state implementation plan (SIP) submittal to address the infrastructure requirements for the 2012 fine particulate matter (PM<INF>2.5</INF>) national ambient air quality standards (NAAQS). EPA is extending the comment period due to erroneously omitting the technical support document (TSD) in the docket. This proposed rule corrects this omission and provides notice of the availability of the TSD which supports EPA's analysis. All comments received on or before July 24, 2017 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.
