Approval and Promulgation of Air Quality Implementation Plans; Rhode Island; Rhode Island Low Emission Vehicle Program

The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the State of Rhode Island Department of Environmental Management. The regulations adopted by Rhode Island include the California Low Emission Vehicle (LEV) II light-duty motor vehicle emission standards effective in model year 2008, the California LEV II medium-duty vehicle standards effective in model year 2009, and greenhouse gas emission standards for light-duty motor vehicles and medium-duty vehicles effective with model year 2009. The Rhode Island LEV regulation submitted also includes a zero emission vehicle (ZEV) provision. Rhode Island has adopted these revisions to reduce emissions of volatile organic compounds (VOC) and nitrogen oxides (NO<INF>X</INF>) in accordance with the requirements of the Clean Air Act (CAA), as well as to reduce greenhouse gases (carbon dioxide, methane, nitrous oxide, and hydrofluorocarbons). In addition, Rhode Island has worked to ensure that their program is identical to California's, as required by the CAA. These actions are being taken in accordance with the CAA.
