Minutes/Notes

Introduction to overall Collaborative Workgroup effort

  • Will1st time states, tribes, MJOs, and EPA will collaborate to develop a National emissions modeling platform
  • There are approximately 10 workgroups
  • The overarching goal is to develop data files for the 2016 Modeling Platform and projections out to 2023 and 2028 that MJOs, tribes, states, and EPA can modify and augment to address their analysis and planning needs. Examples of uses: Ozone and particulate matter (PM), regional haze modeling.
  • There will be posted3 followingmain phases of the meetingeffort that Chris will talk more about when he introduces this workgroup’s charge.

Introduction to Nonpoint Workgroup

  • Chris reviewed each section of the Charge, which is currently in draft form.
  • For Table 1:
    • Chris asked for feedback regarding the source categories (Section 6.2, Table 1). Caroline asked interested members to provide top 3 priorities via email. The answers will be compiled and used to edit the Charge. The co-chairs want this workgroup to be a collaborative effort and welcome any suggestions for the charge.
    • Expected pollutants – only CAPs should be considered, however we should also include NH3, especially for Ag-related categories
    • Oil & gas will not be included since this is a separate workgroup

Timeline and Milestones

  • This was covered in Section 3 of the Charge.
    • January 2018: 2016alpha
    • Summer 2018: 2016beta with projections to 2028
    • Early 2019: 2016v1.0 with projections to 2023 and 2028

Update on 2016alpha

  • Jennifer Snyder gave an update on the initial data for the workgroup. We are hoping to have it in hand near the beginning of February.

Administrative Items

  • Recurring Meeting time: 4th Monday of the Month at 2pm EST

Questions/Comments

  • For Table 1, consider including silage.
    • Chris S. will check to see if California has documentation on emissions from silage operations, however Stacy Allen (MO) mentioned that silage ops in the Midwest are much different than those in CA.
  • For Table 1, composting should be included
  • From the NOMAD work, it was determined that the Ag tilling method from Abt has an incorrect number of passes – too many passes for some areas of the country. The group should be sure to follow up on this (Lynn Deahl)
  • Check to be sure that CAFO methodology includes VOC and dust from hooves (Stacy Allen)
  • What types of point sources should be subtracted (reconciled) with the ICI combustion tool data (John Barnes)
    • Chris suggested that this be deferred until a later date after larger issues have been ironed out.
  • For projections, what are the current growth factors used by EPA?
    • Caroline will work to get these to the group
  • How does this project fit in with EPA’s 2017 effort (Walter Simms).
    • One answer is that the 2016 modeling platform is needed for Regional Haze development, work that can’t wait until the 2017 NEI is finalized.
  • 2014 NEI (or modeling platform v.7) CAP emissions group-summed nationally by major category would be helpful in determining which categories should be prioritized
    • Chris S. will compile this and send it out.
