Minutes/Notes

Aircraft Subgroup

  • An interest call about an aircraft subgroup will meet Wednesday, April 4, 2018 at 2pm EDT. Email Caroline if you would like to be added to the meeting invitation.

QA Comparison File and 2016 Point Update

  • Tammy reviewed the file Ron Ryan sent out to states. A few people mentioned not receiving it, probably because another representative at the state has worked on it - send an email to Caroline and she will ask Ron if he can send it along.
  • Questions from General Collaborative Update meeting:
    • How many states submitted point sources for 2016?
      • 48 states (KY and MA missing), DC, PR, 20 locals, and 2 tribes submitted at least one facility. Out of approx. 63,000 non-airport facilities in 2014v2 NEI, about 22,000 of those were reported for 2016.
      • We plan to do an analysis of the percentage of emissions these 22,000 facilities represent when the 2016 point flat file is ready.
  • Update on 2016 Flat File Progress
    • How do members want to see the data? (e.g., non-EGU point separated? Pt_oilgas not separate out? Whole Point file?)
      • Members would like to see both the entire Point file and the non-EGU Point separated file.
    • As a note, the non-EGU and EGU facilities are separated using the IPM_YN column. If an entry appears in this column, it is separated out as an EGU.
  • If you want to see your states' submitted data before the 2016 flat file is ready, follow the instructions in the tutorial to create a flat file in EIS from the submitted data: Flatfile Generation Tutorial.

2014v2 Emission Totals by Subsector

  • Caroline reviewed the graph of subsector totals for CAPS with the group. This is available on the google drive, or can be requested via email if you do not have access.

2011 Growth and Control comparisons

  • Caroline reviewed the ftp links that members can use to see how growth and controls factors projected emissions from 2011 to 2023 and 2028. This will be most helpful for projections after we set the base case.

Reports: ftp://newftp.epa.gov/Air/emismod/2011/v3platform/reports/

Projection and Control packets: ftp://newftp.epa.gov/Air/emismod/2011/v3platform/2023en_update/, ftp://newftp.epa.gov/Air/emismod/2011/v3platform/2028emissions/

  • If you have issues accessing any of the data covered today, contact Caroline or Tammy.

Review/Answer Questions from last call

  • Specification Spreadsheet wording could be improved and the example spreadsheet may not be the most appropriate format/example for point source work. It is an agriculture spreadsheet.
    • This has been raised by a few people in other groups too and is being considered

  • Why does the charge have the group projection to 2028 first, rather than 2023?
    • This appears to have been a typo in the example charge given. It will be updated to include 2023. We will be working on projections to both years.

  • How is the group going to get data/input on data from SLTs that are not participating on work group call? How to fill in data not submitted by SLTs for 2016? 2014v2 projected to 2016? Ask SLTs to submit all collected data to EIS even if not required by AERR? Other options?
    • We just had submissions from states in mid-January for Calendar year 2016 emissions from S/L/Ts which included CAP emissions from Type A sources. However, Ron Ryan stated that most states report Type B source annually even though these sources are only required to report triennially. If we have missing data, we would grab the reported data from the most recent triennial (in this case 2014) NEI and use it to gap fill.  NC reports Type B sources annually. 

  • How to treat small power generators, i.e., peaking units? Will these units be included in non-EGU Point?
    • There was much discussion on this topic including ERTAC and IPM model uses and definitions.  EIS identifies these sources based on the IPM model and these sources are found in the IPM NEEDS file. Whichever units are identified as EGU-generators will be in the EGU group. At EPA, if a unit is modeled by IPM, then it is an EGU. IPM NEEDS file contains Municipal Waste Combustors (MWC).

Additional Notes from Ron Ryan

  • A review and comparisons file of the S/L/Ts 2016 point submittals as sent out to all S/L/Ts on Tues 2/20, just after the call. S/L/ts are asked to review for possible edits needed and get any edits into their EIS datasets by May 15 at the latest.

  • There is already a “draft” 2016 point inventory of sorts available in EIS for any EIS user’s access. It contains only the S/L/T 2016 point submittals, with no EPA augmentation or gap-filling for smaller facilities from 2014 NEI. It can be viewed, summarized, or filtered from EIS by using dataset name = “2016RAS”, which means “Responsible Agency Selection” – only what the Responsible S/L/T Agency for each facility submitted is included. The completeness of this RAS draft will vary from State-to-State depending on whether each S/L/T submitted all or most of their facilities or whether they only submitted the very largest emitters that are required for the non-triennial NEI years.

  • We are targeting March 15 to have a more complete “draft” 2016 point inventory available in EIS. This draft will include EPA PM Augmentation (largely just summing S/L/T-reported filterable and condensible PM pieces) and using the 2014 NEI to gap-fill for any smaller, non-reported 2016 facilities that are still shown as “operating”. It will also include EPA augmentations where needed for HAPs : 2016 TRI data, HAP Augmentation, and Chromium speciation. Note that we do not expect any S/L/T edits of their submitted data to necessarily be available for that March 15 draft. We do not expect this to impact the utility of the March 15 draft, because the 2016 S/L/T submittals seem to be exceptionally clean, especially for criteria pollutants.

  • We are targeting July 1 to have the final 2016 point inventory available in EIS.

Aircraft Subgroup

  • No volunteer yet to lead subgroup. Some discussion about whether this subgroup is needed or if the whole group should work on these sources.  Suggested to group that aircraft subgroup is needed and some members have indicated interest in working on this subgroup.  Caroline will talk to some of the interested members and management about the subgroup.

  • CY2017 draft should be ready by mid-summer.  Most of work would be focused on projections.

Upcoming data being sent

  • Caroline will be gathering and sending out current data about existing growth and controls used for projections from EPA. She will also compile a summary/plot of emission totals by subsector.

  • Ron is sending a draft out to states today of 2016 EIS emissions.

  • For closures, a list of facilities/sources marked for shutdown can be obtained as a report from EIS.

Action Items

  • If you want to be on the aircraft subgroup and have not told us, please email Caroline or Tammy.

  • Review data sent out in the coming weeks and be ready to discuss in March.

Minutes/Notes

Introduction to overall Collaborative Workgroup effort

  • Overall goals of this workgroup are to collaboratively generate the data files necessary to develop the 2016 Emission Modeling Platform. Create a projection methodology for future years 2023 and 2028 to augment the needs of SLTs. There are 10 groups working on this effort and the work will be accomplished in three phases;
    • Determine the appropriateness of the 2016alpha inventory developed by EPA and suggest improvements.
    • Develop 2016beta and projection methodology to 2028.
    • Finalize 2016v1 with projections to 2023 and 2028
  • For those SLTs that cannot access GoogleDrive at work, files have been copied to Wiki. Another strategy for file sharing may have to be implemented depending on file size.

Introduction to non-EGU Point Workgroup

  • Introduced group to Point Non-EGU WorkGroup Charge. The whole process should be approximately one year. As the group works through items in charge, the specification sheet needs to be completed.
  • Charge workgroup organization: there will be two sub-groups established to target specific data issues;
    • Projection-discuss and develop projection methodology for 2023 and 2028.
    • Aircraft-discuss and develop how to handle aircraft in point non-egu inventory
  • Initial data file, draft 2016alpha, should be available the first or second week of February. Ron Ryan says that 2014v2 point source data has been completed and is available in EIS.

Administrative Items

  • Recurring Meeting: 3rd Tuesday at 1400 EST. Next meeting will be February 20.
  • Google Drive
  • Wiki
    • For those who cannot access Google Drive, smaller files will be posted on Wiki when possible

Action Items

  • Members of work group read over charge and provide comments if you have any.
  • Caroline will work on Google Drive access issue.
  • Let co-chairs know if you have an interest in participating on sub-groups or if you would like to lead one of the subgroups.

Questions and Comments from Meeting

  • How is the group going to get data/input on data from SLTs that are not participating on work group call?
  • Specification Spreadsheet wording could be improved and the example spreadsheet may not be the most appropriate format/example for point source work. It is an agriculture spreadsheet.
    • There are field in EIS that are used when submitting data, could these be used for documentation?
  • How to fill in data not submitted by SLTs for 2016? 2014v2 projected to 2016? Ask SLTs to submit all collected data to EIS even if not required by AERR? Other options?
  • What about point subtraction? How will we avoid double counting?
  • Use trending methodology to generate projections?
  • Aircraft in 2016alpha? Or grown from 2014v2? It was noted that states may only submit partial inventories for 2016 aircraft.
  • Format for final deliverable data files=Smoke input files.
  • Will SPECIATE be used to augment 2016alpha? Sent email to Madeleine Strum
  • What do you see as the main use for the products of this workgroup?
    • Main use of 2016 Emission Modeling Platform would be PM and Ozone modeling. May be able to incorporate work by MARAMA on EMF.
  • How to treat small power generators, i.e. peaking units? Will these units be included in non-EGU point? There are identifiers for these units and could be used to flag units in SMOLE files. Northeast has been working on a similar issue and may have guidance.
    • Ron Ryan noted that many of these go into an IPM file but some do exist in non-EGU file. How will we identify these units?
    • May be determined by overall project coordinators Alison and Zac.
  • Why does the charge have the group projecting to 2028 first rather than 2023?

Next Call: February 20, 2018 at 2pm EST
