Approval and Promulgation of Air Quality Implementation Plans; District of Columbia; Withdrawal of Final Rule

Because EPA received adverse comments, EPA is withdrawing the direct final rule for the conditional approval of revisions to the District of Columbia state implementation plan (SIP). EPA published the direct final rule on February 25, 1999 (64 FR 9272), conditionally approving the District of Columbia's requirements for reasonably available control technology (RACT) on major sources of nitrogen oxides. EPA stated in the direct final rule that if EPA received adverse comments by March 29, 1999, EPA would publish a timely notice of withdrawal in the Federal Register. EPA subsequently received adverse comments on that direct final rule. EPA will address the comments received in a subsequent final action and issue a final rule based on the parallel proposal also published on February 25, 1999 (64 FR 9289). As stated in the parallel proposal, EPA will not institute a second comment period on this action.
