  1. California Low Emission Vehicle (LEV II) Program in the Northeast Coralie Cooper Transportation Program Manager Northeast States for Coordinated Air Use Management December 19, 2003

  2. Presentation Overview • Summary of emissions reductions of the LEV II Program over the Tier 2 program. • Summary of modeling approach. • Conclusions.

  3. Summary of Emissions Reductions: LEV II compared to Tier 2 Annual Emissions Benefits of the LEV II Program in 2020 [1] Toxics include benzene, 1,3 butadiene, formaldehyde and acetaldehyde * annual tons reduced equal to industrial process or agricultural emissions for the New England states.

  4. Inventory of NE Air Toxics (1996)

  5. California LEV Benefits (cont.) • LEV program will continue to require the most stringent emissions standards in the nation. • CA is considering development of LEV III standards, while the federal program will not change for a decade or more. • CA is also developing motor vehicle GHG emissions standards.

  6. Summary of Modeling Approach • Tier 2 allows manufacturers to certify vehicles to 1 of 11 standards. NESCAUM study assumed most vehicles certified to “bin 5.” EPA certification data for 2003 and 2004 confirm this approach. • Near zero evaporative standard for partial ZEV vehicles. • Assumed LEV same as Tier 2. • Benefits in the NESCAUM study are conservative because of the assumption that all Tier 2 vehicles meet LEV II evaporative standards, even though LEV II standards are 60% more stringent than Tier 2.

  7. Conclusions • NESCAUM study demonstrates a significant HC and toxics benefit with adoption of LEV II in lieu of Tier 2. • The study demonstrates a modest CO2 reduction from LEV II adoption. It does not take into account any CO2 reductions that would result from the GHG standard implementation • Future changes to the California program (LEV III, GHG regulations) will further increase the emissions reductions realized in LEV II states.
