Official Release of EMFAC2007 Motor Vehicle Emission Factor Model for Use in the State of California
Document Number: E8-876
Type: Notice
Date: 2008-01-18
Agency: Environmental Protection Agency
EPA is approving and announcing the availability of the latest version of the California EMFAC model for use in state implementation plan (SIP) development in California. EMFAC2007 is the latest update to the EMFAC model for use by California state and local governments to meet Clean Air Act (CAA) requirements. The new model, which is based on new and improved data, calculates air pollution emission factors for passenger cars, trucks, motorcycles, motor homes and buses. Today's notice also sets the date after which EMFAC2007 is required to be used statewide in all new regional emissions analyses and carbon monoxide (CO) hot-spot analyses for transportation conformity determinations in California. EPA also intends to approve EMFAC2007 in the future for particulate matter (PM10 and PM2.5) hot-spot analyses in California, once EPA issues quantitative hot-spot modeling guidance for such analyses. Since the EMFAC model is used only in California, EPA's approval of the model does not affect MOBILE model users in other states.
Approval and Promulgation of Air Quality Implementation Plans; Designation of Areas for Air Quality Planning Purposes; Arizona; San Manuel Sulfur Dioxide State Implementation Plan and Request for Redesignation to Attainment
Document Number: E8-804
Type: Proposed Rule
Date: 2008-01-18
Agency: Environmental Protection Agency
EPA is proposing to approve the maintenance plan for the San Manuel Area in Pinal and Pima Counties, Arizona, as a revision to the Arizona state implementation plan, and to grant the request submitted by the State to redesignate this area from nonattainment to attainment of the national ambient air quality standards for sulfur dioxide (SO2) for the San Manuel SO2 nonattainment area. EPA is proposing this action in accordance with the Clean Air Act.
Approval and Promulgation of Air Quality Implementation Plans; Designation of Areas for Air Quality Planning Purposes; Arizona; San Manuel Sulfur Dioxide State Implementation Plan and Request for Redesignation to Attainment
Document Number: E8-803
Type: Rule
Date: 2008-01-18
Agency: Environmental Protection Agency
EPA is taking direct final action under the Clean Air Act to approve the Final State Implementation Plan Revision, San Manuel Sulfur Dioxide Nonattainment Area, March 2007 as a revision to the Arizona state implementation plan. The Arizona Department of Environmental Quality developed this plan to maintain the sulfur dioxide national ambient air quality standards in the San Manuel, Arizona area and to request redesignation of the area to attainment. The maintenance plan contains various elements, including contingency provisions that will be implemented if measured ambient concentrations of sulfur dioxide are above certain trigger levels. EPA is also approving the State of Arizona's request for redesignation of the San Manuel area from nonattainment to attainment for the sulfur dioxide standards. EPA is taking these actions consistent with provisions in the Clean Air Act that obligate the Agency to approve or disapprove submittals of revisions to state implementation plans and requests for redesignation. The intended effect is to redesignate the San Manuel, Arizona sulfur dioxide nonattainment area to attainment, and to provide for maintenance of the standard for the ten-year period following redesignation.
