Kickoff Meeting 11/30/2023

Agenda (meeting notes added)

  • Introductions
  • Discuss the base year 2022
    • VMT was requested voluntarily from the states
      • Typically we get county level VMT from FHWA. FHWA could not provide VMT for 2021.
        • We have a pending request with FHWA to get anything possible for 2022
      • States that provided data thus far: GA, Jefferson County KY, NY, ME, AK, VA, WV, MD, WA, CO, MI, NY, KS, TX
      • States that have not provided emissions projected forward from 2020
      • 2021 state adjustments were based on state total VMT
    • VPOP
      • 2021 was held constant from 2020. For 2022, we may want to make some adjustments.
        • FHWA state statistics
    • Other activity discussions
      • ONI from OTAQ
      • Hoteling based on VMT
      • Starts from contractor- GA provides their own
    • EPA has looked at FHWA TMAS Class Data for 2021. VMT fraction by hour, by state, by vehicle class.
      • Have not started on 2022
    • Representative counties, same as what was used in 2020 NEI
      • Taskforce can review and make suggestions
    • SMOKE/MOVES w/MOVES4
  • Nonroad
    • Load factors too high?

Happy New Year!

Agenda for 1/11/24

  • EPA can go over onroad results for 2021. The 2021 used MOVES4. Some inputs will be the same for 2020, 2021, and 2022 (e.g., rep counties?). Presentation (made to MJO MOVES) attached.
  • VPOP discussion (constant vs adjustments).
  • States that provided VMT data thus far: CT, GA, MA, NY, MD, WA, ME, VA, CO, TN, AK, WV, KS, NH, NJ, OR, DE, SC, NC, TX, WI, MI, NC and Jefferson Co. KY
  • Still don’t know if/what county-level data we will get from FHWA.
  • EPA starting on FHWA TMAS Class Data for 2022. VMT fraction by hour, by state, by vehicle class.
  • Discuss proposed plans for age distributions for the 2022 base year.
  • Non-road: will 2022 population estimates be used and if so can states submit their own 2022 population?
  • Analytic years: Do we want to make adjustments to rep counties based on changes to I/M programs?
