Approval and Promulgation of Air Quality Implementation Plans; Virginia; Revisions to Clean Air Interstate Rule Emissions Trading Program
EPA is approving a State Implementation Plan (SIP) revision submitted by the Commonwealth of Virginia. The revision, which amends the Virginia Clean Air Interstate Rule (CAIR) trading program, is comprised of technical corrections and revisions to the definition of a cogeneration unit to ensure the Commonwealth's CAIR trading program is consistent with federal CAIR requirements. This action is being taken under the Clean Air Act (CAA).
Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; Control of Nitrogen Oxides Emissions From Glass Melting Furnaces
EPA is approving a State Implementation Plan (SIP) revision submitted by the Commonwealth of Pennsylvania. The SIP revisions pertain to the control of nitrogen oxide (NOX) emissions from glass melting furnaces. EPA is approving these revisions to reduce NOX emissions from glass melting furnaces in accordance with the requirements of the Clean Air Act (CAA).
Approval and Promulgation of Air Quality Implementation Plans; Maryland; Update to Materials Incorporated by Reference
EPA is updating the materials submitted by Maryland that are incorporated by reference (IBR) into the Maryland State Implementation Plan (SIP). The regulations affected by this update have been previously submitted by the Maryland Department of the Environment (MDE) and approved by EPA. This update affects the SIP materials that are available for public inspection at the National Archives and Records Administration (NARA), the Air and Radiation Docket and Information Center located at EPA Headquarters in Washington, DC, and the EPA Regional Office.
Approval and Promulgation of Implementation Plans; New Mexico; Federal Implementation Plan for Interstate Transport of Pollution Affecting Visibility and Best Available Retrofit Technology Determination
EPA is disapproving a portion of the State Implementation Plan (SIP) revision received from the State of New Mexico on September 17, 2007, for the purpose of addressing the ``good neighbor'' requirements of section 110(a)(2)(D)(i) of the Clean Air Act (CAA or Act) for the 1997 8-hour ozone National Ambient Air Quality Standards (NAAQS or standards) and the 1997 fine particulate matter (PM2.5) NAAQS. In this action, EPA is disapproving the New Mexico Interstate Transport SIP provisions that address the requirement of section 110(a)(2)(D)(i)(II) that emissions from New Mexico sources do not interfere with measures required in the SIP of any other state under part C of the CAA to protect visibility. We have found that New Mexico sources, except the San Juan Generating Station, are sufficiently controlled to eliminate interference with the visibility programs of other states. EPA is promulgating a Federal Implementation Plan (FIP) to address this deficiency by implementing nitrogen oxides (NOX) and sulfur dioxide (SO2) emission limits necessary at the San Juan Generating Station (SJGS), to prevent such interference. EPA found in January 2009 that New Mexico had failed to submit a SIP addressing certain regional haze (RH) requirements, including the requirement for best available retrofit technology (BART). The Clean Air Act required EPA to promulgate a FIP to address RH requirements by January 2011. This FIP addresses the RH BART requirement for NOX for SJGS. In addition, EPA is implementing sulfuric acid (H2SO4) hourly emission limits at the SJGS, to minimize the contribution of this compound to visibility impairment. This action is being taken under section 110 and part C of the CAA.
