Approval and Promulgation of Air Quality Implementation Plans; Maine, New Hampshire, Rhode Island, and Vermont; Interstate Transport of Air Pollution

EPA is approving State Implementation Plan (SIP) revisions submitted by the Maine Department of Environmental Protection (ME DEP), the New Hampshire Department of Environmental Services (NH DES), the Rhode Island Department of Environmental Management (RI DEM) and the Vermont Department of Environmental Conservation (VT DEC). These SIP revisions address provisions of the Clean Air Act that require each state to submit a SIP to address emissions that may adversely affect another state's air quality through interstate transport. The EPA has concluded that all four States have adequate provisions to prohibit in- state emissions activities from significantly contributing to the nonattainment, or interfering with the maintenance, of the 2008 ozone National Ambient Air Quality Standards (NAAQS) in any other state. The intended effect of this action is to approve the SIP revisions submitted by Maine, New Hampshire, Rhode Island, and Vermont. This action is being taken under the Clean Air Act.
