federal transportation conformity rule
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
conformity tests
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
conformity considerations
Conformity Considerations
  • Upcoming New Transportation Model
  • AQMP/SIP Adoption Schedules
  • 2004 vs. 2008 RTP Performance
