Air Plan Approval; Connecticut; Revision of the Low Emission Vehicles Program

The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the State of Connecticut on December 14, 2015. This SIP revision includes Connecticut's revised regulation for new motor vehicle emission standards. Connecticut has updated its rule to be consistent with various updates made to California's low emission vehicle (LEV) program. The Connecticut LEV regulations also include updates to the zero emission vehicle (ZEV) provision. Connecticut has adopted these revisions to reduce emissions of volatile organic compounds (VOC), particulate matter (PM), and nitrogen oxides (NOX) in accordance with the requirements of the Clean Air Act (CAA), as well as to reduce greenhouse gases. The intended effect of this action is to propose approval of Connecticut's December 14, 2015 SIP revision. This action is being taken under the CAA.
