Approval and Promulgation of Air Quality Implementation Plans; Delaware; Withdrawal of Direct Final Rule

Due to adverse comments, EPA is withdrawing the direct final rule to approve Delaware's State Implementation Plan (SIP) revision. The SIP revision pertains to the modifications to the ambient air quality standards for ozone and fine particulate matter. In the direct final rule published on July 18, 2005 (70 FR 41146), we stated that if we received adverse comments by August 17, 2005, the rule would be withdrawn and not take effect. EPA subsequently received adverse comments. EPA will address the comments received in a subsequent final action based upon the proposed action also published on July 18, 2005 (70 FR 41166). EPA will not institute a second comment period on this action.
