Approval and Promulgation of Air Quality Implementation Plans; Connecticut; Removal of Oxygenated Gasoline Requirement for the Connecticut Portion of the New York-N. New Jersey-Long Island Area (the ``Southwest Connecticut Area'')

요약

In today's action, EPA is approving a State Implementation Plan (SIP) revision under the Clean Air Act submitted by the State of Connecticut on October 7, 1999 to remove Connecticut's oxygenated gasoline program as a carbon monoxide control (CO) measure from the SIP. The SIP revision includes revised regulations adopted by Connecticut which redefine the control period for oxygenated gasoline in southwest Connecticut such that the oxygenated gasoline program is not required to be implemented except in the unlikely event of a violation of the CO standard in the area. EPA supports this regulatory amendment since it is consistent with the CO redesignation and maintenance plan for the southwest Connecticut area that EPA approved on March 10, 1999 (64 FR 12005).
