TOC
EGU Task Force / National Workgroup
Co-leads: Susan McCusker, Alison Eyth
Resources
- 2016 EMP specification sheets for IPM & ERTAC EGUs https://views.cira.colostate.edu/wiki/wiki/10202
- 2016v3 platform: https://www.epa.gov/air-emissions-modeling/2016v3-platform
- 2020 platform: https://www.epa.gov/air-emissions-modeling/2020-emissions-modeling-platform
Kickoff Meeting 11/30/2023
Agenda
- Identify scope of this task force vs National EGU WG
- Review methods for 2022 inventory development
- EGU with CEMS hourly data
- EGUs without CEMS data (small or other EGUs)
- Non-EGUs with CEMS - these have hourly data but haven't been used in EPA platforms
- Discuss file structure to accommodate EPA ptegu and ERTAC ptertac platform choice
- Discuss methods for projecting 2022 to the analytic years
- EGUs with CEMS, EGUs without CEMS data, nonEGUs with CEMS [with ERTAC and IPM]
- How can we manage / warehouse review materials
- Recommend topics for this task force vs EGU workgroup
- Schedule standing monthly calls [or use existing EGU workgroup calls 4th Thursday at 2 Eastern?]
Notes
1. Identify scope of this vs national WG
Monthly calls would be helpful to coordinate with ERTAC group, could be on 4th Thursday 2 Eastern regular EGU WG meeting.
Are municipal waste combustors (MWCs) covered in this? YES
2. Current methods for EGU emissions modeling
Non-EGUs with CEMS: Plan to discuss at the next EGU WG call – will discuss at this call how EPA has been handling vs how ERTAC has handled
ACTION: Crosswalk between NEEDS, NEI, ERTAC (uses ORIS = CAMD IDs) needs to be updated for 2022 platform
EGUs without CEMS – consider how these are projected and temporally allocated / assigned to peaking and non-peaking profiles – good to circle back to this
3. File structure to accommodate EPA ptegu and ERTAC ptertac platform choice
File structure for EPA / ERTAC platform choices – ERTAC universe of units is mostly the same as ptegu but not exactly the same. Doris suggested a structure that has EGU / non-EGU + reporting to CAMD / not reporting to CAMD. Perhaps ptegu_other, and ptnonegu
- ERTAC modelers would like to remove projection data done by IPM and replace with ERTAC data
- It would help them if the file structure is a bit more granular – this would be easier when there are units that use general profiles
- They would like to see a file that has the part 75 reporters all together [but we treat them as non-EGUs]
- They will share the mapping chart and we can consider how to refine the platform
4. Managing review materials
We will use a Wiki.
5. Methods for projecting to analytic years
Parsed outputs files for IPM are useful.
How to handle carrying forward data from earlier years and retirements of those?
- Make sure you look at the latest NEEDS which is updated quarterly. Also see the comparisons across multiple years.
- It would help to have a summary for states how sources that are permitted but not yet running are reflected.
- Many new units are renewables
- Some projects are ‘for sure’ and some are ‘potential’ – can be sorted from EIA 860 data.
At a future meeting, it would be helpful to share how ERTAC tool handles new units – both in the base year and in the analytic year
6. Next meetings
EGU WG 12/14 @ 11 Eastern: - Serpil will add anyone on invitation list for this task force into that call and next year’s calls - 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)
