Air Plan Approval; California; Yolo-Solano Air Quality Management District; Negative Declarations
The Environmental Protection Agency (EPA) is proposing to approve a revision to the Yolo-Solano Air Quality Management District (YSAQMD or ``District'') portion of the California State Implementation Plan (SIP). This revision concerns the District's negative declarations for several volatile organic compound (VOC) source categories included in its Reasonably Available Control Technology (RACT) State Implementation Plan Analysis. We are proposing to approve these negative declarations under the Clean Air Act (CAA or ``the Act''). We are taking comments on this proposal and plan to follow with a final action.
Approval and Promulgation of Air Quality Implementation Plans; Virginia; Interstate Transport Requirements for the 2012 Fine Particulate Matter Standard
The Environmental Protection Agency (EPA) is proposing to approve a state implementation plan (SIP) revision submitted by the Commonwealth of Virginia (the Commonwealth or Virginia). This revision pertains to the infrastructure requirement for interstate transport of pollution with respect to the 2012 fine particulate matter (PM2.5) national ambient air quality standards (NAAQS). EPA is approving this revision in accordance with the requirements of the Clean Air Act (CAA).
Interstate Transport Prongs 1 and 2 for the 2012 Fine Particulate Matter (PM2.5
The Environmental Protection Agency (EPA) is proposing to approve portions of State Implementation Plan (SIP) submissions from Colorado, Montana, North Dakota, South Dakota and Wyoming addressing the Clean Air Act (CAA or Act) interstate transport SIP requirements for the 2012 annual Fine Particulate Matter (PM2.5) National Ambient Air Quality Standards (NAAQS). These submissions address the requirement that each SIP contain adequate provisions prohibiting air emissions that will have certain adverse air quality effects in other states. The EPA is proposing to approve portions of these infrastructure SIPs for the aforementioned states as containing adequate provisions to ensure that air emissions in the states will not significantly contribute to nonattainment or interfere with maintenance of the 2012 annual PM2.5 NAAQS in any other state.
Approval and Promulgation of Air Quality State Implementation Plans; California; Chico Redesignation Request and Maintenance Plan for the 2006 24-hour PM2.5
The Environmental Protection Agency (EPA) is proposing to approve, as a revision of the California state implementation plan (SIP), the State's request to redesignate the Chico nonattainment area to attainment for the 2006 24-hour fine particulate matter (PM2.5) national ambient air quality standard. The EPA is also proposing to approve the PM2.5 maintenance plan and the determination that contributions from motor vehicle emissions to the PM2.5 pollution in the Chico nonattainment area are insignificant. The EPA is proposing this action because the SIP revision meets the requirements of the Clean Air Act and EPA guidance for such plans. We are taking comments on this proposal and plan to follow with a final action.
Approval and Promulgation of Implementation Plans; New Jersey; Motor Vehicle Enhanced Inspection and Maintenance Program
The Environmental Protection Agency (EPA) is approving a request from New Jersey to revise its State Implementation Plan (SIP) to incorporate revisions to the motor vehicle enhanced inspection and maintenance (I/M) program. New Jersey has made several amendments to its I/M program and has requested that the SIP be revised to include these changes. EPA is approving New Jersey's amendments to its I/M program to discontinue idle tests on model years 1995 and older light duty gasoline vehicles, idle tests on heavy-duty gasoline vehicles and gas cap leak testing. In addition, heavy-duty gasoline vehicles equipped with on-board diagnostics (OBD) will be subject to OBD testing with this revision. The intended effect of this action is to maintain consistency between the State-adopted rules and the federally approved SIP.
Approval and Promulgation of Implementation Plans; Texas; Revisions to Permitting and Public Participation for Air Quality Permit Applications
