Approval and Promulgation of Air Quality Implementation Plans; Delaware; Nonattainment New Source Review; Emission Offset Provisions; Reopening of Comment Period

Environmental Protection Agency (EPA) is reopening the comment period for a notice of proposed rulemaking (NPR) published on May 26, 2015. In the NPR, EPA proposed disapproval of a revision to the Delaware State Implementation Plan (SIP) related to nonattainment New Source Review (NSR) preconstruction permit program requirements for emission offsets. A commenter requested additional time to review the proposal and prepare comments. In response to this request, EPA is reopening the comment period for this proposal through August 14, 2015. All comments received on or before August 14, 2015 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 reopening of this comment period will be accepted and considered.
