Approval and Promulgation of Implementation Plans; New Mexico; Regional Haze and Interstate Transport Affecting Visibility State Implementation Plan Revisions

The Environmental Protection Agency (EPA) is taking final action under the Clean Air Act (CAA) to approve a revision to the New Mexico Regional Haze State Implementation Plan (SIP) that addresses the Best Available Retrofit Technology (BART) requirement for oxides of nitrogen (NO<INF>X</INF>) for the Public Service Company of New Mexico (PNM) San Juan Generating Station (SJGS) in San Juan County, New Mexico. EPA is also taking final action under the CAA to approve a revision to the New Mexico Visibility Transport SIP that addresses the CAA requirement that emissions from sources in New Mexico do not interfere with programs in other states to protect visibility. The SIP meets this requirement through emission limitations for NO<INF>X</INF> and sulfur dioxide (SO<INF>2</INF>) at SJGS.
