Approval and Promulgation of Air Quality Implementation Plans; District of Columbia; Oxygenated Gasoline Program

Riepilogo

EPA is proposing a limited approval/limited disapproval of a State Implementation Plan (SIP) revision submitted by the District of Columbia. This revision implements an oxygenated gasoline program in the District of Columbia. The intended effect of this action is to propose approval of those subsections of the District of Columbia Municipal Regulations (DCMR) which pertain to oxygenated gasoline for the limited purpose of strengthening the District of Columbia SIP which currently has no requirements for an oxygenated gasoline program. In addition, this action is intended to propose disapproval of those subsections of the DCMR which pertain to oxygenated gasoline for the limited purpose of allowing the District of Columbia the opportunity to correct the deficiencies in the regulation which result in its failure to meet all requirements of the Clean Air Act. This action is being taken under Section 110 of the Clean Air Act.
