## Abstract

EPA is approving State Implementation Plan (SIP) revisions submitted by the States of Rhode Island (RI) and Massachusetts (MA). This action consists of approving regulations in RI and MA which are part of a regional nitrogen oxide (NO<INF>X</INF>) reduction program designed to reduce stationary source NO<INF>X</INF> emissions during the ozone season in the Ozone Transport Region (OTR) of the northeastern United States. (Section 184(a) of the Clean Air Act defines an ozone transport region in the northeastern United States comprised of the States of Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, and the Consolidated metropolitan Statistical Area that includes the District of Columbia.) Additionally, this action involves the approval of a source specific order which establishes alternative NO<INF>X</INF> reasonably available control technology (RACT) requirements for four boilers at the Rhode Island Economic Development Corporation (RIEDC). These SIP revisions were submitted pursuant to section 110 of the Clean Air Act (CAA).
