Task Force Wikis

The projections workgroup organized into task forces to review the projection methods and data for different inventory sectors. Notes and work products for the task forces are available in the following wikis.

Electricity Generating Units (EGU) Co-leads: Alison Eyth and Susan McCusker

Industrial Point, Co-leads: Zac Adelman and Rhonda Payne

Nonpoint, Co-leads: Lindsay Dayton and Andy Bollman

Onroad/Nonroad, Co-leads: Janice Godfrey and Farren Thorpe

Oil & Gas, Co-leads: Jeff Vukovich and Tom Richardson

Marine/Airports/Rail (MAR), Co-leads: Janice Godfrey and Mark Janssen

Projections Workgroup Meetings

Workgroup coordinators: Zac Adelman and Alison Eyth

December 6, 2023

EGU

Will meet with national EGU WG 12/14 @ 11 Eastern: We can discuss Part 75 sources – non-traditional discussion at this call “industrial units”
Next call Jan 25th at 2 Eastern (4th Thursday at 2 Eastern)

Industrial point

next call 12/18 at 1PM eastern
Sent recent base year state+SCC level report emissions for 2016-2021
Alison sent closure list
Point source subtraction is a potential issue (esp oil and gas, we address for solvents, there may be other key sectors)

Nonpoint:

ICI fuel combustion is key subsector for point source subtraction
Next meeting is 12/7 at 10AM – will review comments
Considering 2020-2022 first
Qualitatively, sub-sectors impacted by COVID: cremation, sectors that are VMT-related
a summary may be needed to facilitate discussion
See the summary of proposed emissions methods on TF Wiki page

Mobile (onroad/nonroad)

Next meeting Jan 11 at 3:30

Oil and gas

They are going to use national O&G WG call to bring updates to community
will have a projections panel discussion on December 19.
2022 oil and gas emissions work just started – hope to have activity by end of Jan and compute emissions in February; WY is submitting own emissions
Next meeting: December 19 at 2 Eastern, January 11 at 2 Eastern

Marine/airport/rail:

Met Nov 29.
MARAMA CMV 12/13 at 11 to show data for 2021 – there is a standing meeting time 3rd
Next meeting 1/25 at 3PM
No volunteers for co-lead yet
Next WG meeting 1/3 at 4PM eastern

Tom Moore thinks that it would be helpful to prepare summaries over the summer as we get the results including some information on how the projections were done. Some documentation on how 2022 was developed as well.

A spreadsheet could be helpful for certain categories (e.g., nonpoint)

Zac: We may need a ‘todo list’ on Wiki page
Mark J has some graphics he will share on MOVES MJO

Agenda

Introduce the co-leads and review the sector review task force assignments (see below)

Discuss approaches for gathering projection methods for review

Discuss approaches for organizing the task force meetings

Join (or select) a task force if you haven't signed up, or if you signed up for too many

Task Force To Do

Gather the projection methods (TSDs or other EPA docs) for the sources in teach task force

Organize the group and data sources for review

Work with the group to identify the review approach, e.g., how will you prioritize the review and what methods will be used to look through the information

Conduct the review and confirm the projection approach for the sources covered by the task force; identify alternative sources/methods for projection information

Flag new or alternative methods that deviate from the conventional EPA approaches

Document the review process and highlight any significant changes/recommendations

At this meeting, we discussed how the workgroup members could be divided into task forces that could discuss details about projections for the sectors to be covered by each task force.

Notes

October 4, 2023

A this call, the projection methods by sector summary was reviewed and edited. Workgroup members started to indicate the sectors for which they are interested in participating in discussions.

September 6, 2023

At this call, we discussed the proposed charter for the workgroup and priorities for the coming months.

Task Force Action Items

Identify the projection review approach, e.g., how will you prioritize the review and what methods will be used to look through the information

Gather the projection methods (TSDs or other EPA docs) for the sources in teach task force

Review national projections vs regional/state level projection approaches; are there national backstops; when will states need to provide state-specific data to replace the national backstop
Are there regional/state specific control information/rules that can brought into the platform

Conduct the review and confirm the projection approach for the sources covered by the task force; identify alternative sources/methods for projection information
Flag new or alternative methods that deviate from the conventional EPA approaches
Document the review process and highlight any significant changes/recommendations
Where to start: 2020 projections to 2022

Will not have sector specific data for nonpoint data and industrial point (sources that will not have actual 2022 data)
Look at 2021 point data as a surrogate for which sources will not submit 2022 data
Need to identify methods to go from 2020 to 2022
This needs to be done by January
