Fire workgroup for 2022 platform

Contents [hide]

2022 Emissions Modeling Platform Wiki Main Page

Background

Coordinators: Jeff Vukovich (EPA) and Rhonda Payne (WESTAR)

The Fires workgroup will review the 2022 draft and final fire inventories for correctness and completeness. The draft wild and prescribed fire inventory will be prepared using SMARTFIRE2 and BlueSky Pipeline, using activity data sets including the Hazard Mapping System (HMS), Incident Status Summary (ICS-209) reports, and the National Interagency Fire Center (NIFC) shapefiles (formerly GeoMAC). State and local data will also be incorporated where available. For 2022 agricultural fires, a day-specific FF10 point dataset is available and was developed using the same method as the point agricultural fire data in the 2020 NEI.

Jeff sent out an optional data request for those who want to provide data in October. All fire activity data is due by December 8, 2023.

A first draft of the fire inventory was shared on November 22, 2023.

  • OF NOTE
    • The wildland emissions are separated into fireloc files for each state as we normally do for NEI efforts.
    • A few summaries are also available, and the agricultural burn estimates are in a separate sub-folder (ag_burns).
    • Pile burn emissions are not included in this first draft. This tech memo provides more details on how EPA intends to calculate emissions from pile burns.

The first workgroup meeting will be Tuesday, December 12, 2023, at 10 am Eastern.

Meetings

Kickoff Meeting - December 12, 2023

Agenda
  • Welcome and Roll Call
  • Mission
    • Base year is the main goal
    • Wildfires, prescribed burns (with pile burns) and ag burns
    • No plans for analytic year scenarios for fires at EPA
  • Draft version
    • Activity data used
    • Tools used
    • Summary of emissions
  • Pile burns
    • Initial version coming soon
    • States that want to be involved?
  • Activity data request: deadline is Dec 8th
  • Next steps and updated timeline
  • When do we meet again?

Notes

  • Jeff V. went over slides describingdescribing:
    • the mission of the workgroup, which is focused on creating a 2022 CAP and HAP inventory of fires and associated technical documentation. The focus is on the base year emissions, although there are research opportunities to develop analytic years.
    • Activity data and tools used to create the draft inventory - Python modified-SMARTFIRE2 for generating daily acres burned and Bluesky Pipeline for generating daily emissions.
      • Inputs to Python modified-SMARTFIRE2 include HMS, ICS-209, NIFS, FACTS, DOI, and state activity reports.
    • Important changes since 2020 NEI include:
      • moving away from using FEPSv2 emission factors to SERA emission factors in Bluesky Pipeline
      • Specifically estimating emissions for pile burns
      • Using the crop burn module in Bluesky Pipeline
    • Activity and emissions summaries in the draft inventory for wildfire, prescribed fire, and agricultural burning.

  • Jeff presented on next steps:
    • Further refinement of wildfires and continued comparision vs NIFC
    • Possible SERA NOx emission factor updates
    • Provide pile burn estimates for review
    • Incorporate new activity received from SLTs in Python SMARTFIRE2 and rerun Bluesky Pipeline with new activity

  • Updated timeline form 2022v1
    • Initial pile burn estimates (available by 1/5/24), review and feedback due by 2/2/24
    • New version of emissions using all submitted activity (including pile burns) by 3/1/24
    • REVIEW PERIOD for v1: 3/1/4 - 4/30/24
    • Incorporate feedback 5/24 - 6/24, before v1 is finalized in summer 2024.
