Next Steps

• Complete QA of onroad emission inventory results
• Develop State-level, county-level, state/road
  type, and state/vehicle type emission comparisons
  S/L/T agency review
• Verify reasons for significant differences in
  emissions from NEI V2
• Post draft inventory and comparisons
• Respond to comments on draft inventory

23
Next Steps

• Incorporate 2002 final S/L/T VMT as it becomes
  available
• Apply necessary speciation and temporalization
  factors
• Document all emission estimation methods and
  assumptions
