  1. Plans & Programs Technical Advisory Committee May 17, 2007 Jonathan Nadler, Program ManagerAir Quality & Conformity

  2. Federal Clean Air Act (CAA) • Sets national ambient air quality standards • Sets attainment and air plan submittal dates by pollutant based on specific designation of non-attainment areas

  3. Air Quality Planning in the SCAG Region

  4. Mojave Desert Air Basin South Central Coast Air Basin Los Angeles San Bernardino Ventura South Coast Air Basin Riverside Orange Salton Sea Air Basin Imperial 4 AIR BASINS

  5. Mojave Desert AQMD Antelope Valley AQMD Mojave Desert Air Basin South Central Coast Air Basin Ventura County APCD South Coast Air Basin South Coast AQMD Salton Sea Air Basin Imperial CountyAPCD 5 AIR DISTRICTS

  12. Federal Transportation Conformity Rule Federally supported highway/transit project activities must “conform” to SIP • Motor vehicle emissions budgets set permissible upper limit for transportation activities • Applies to non-attainment and maintenance areas for transportation-related criteria pollutants (Ozone, PM2.5, PM10, CO, and NO2) • SCAG receives emission budgets from each air district • Budgets established in SIP • For 2007 AQMPs, budgets based on adopted 2004 RTP and updated socio-economic data

  13. Conformity Tests • Performed for RTP, RTIP, Amendments • Conformity in SCAG Region • 14 Emissions Budgets (precursors) • 9 Interim Emissions Tests • Timely implementation of TCMs (Ventura and South Coast) • Conformity determinations made by FHWA/FTA • Potential for Conformity Lapse • Unable to meet emissions budgets • Jeopardizes federal funding and approvals

  14. Conformity Considerations • Upcoming New Transportation Model • AQMP/SIP Adoption Schedules • 2004 vs. 2008 RTP Performance
