1. Modeling updates

  • GA is doing some testing with 2016 platform working with VA DEQ
  • LADCO is doing PSAT modeling for 2028 - 2016v1 emissions using ERTAC EGUs and some non-EGU corrections
  • LADCO having some run-time issues with SMOKE-MOVES
  • GA is considering MOVES-SMOKE approach
  • Tom M asked about LADCO's used of 2016v1 projected Canadian emissions - yes they are using them
  • NY: just finished preparing 2023 source apportionment runs and plans some 4km modeling
  • EPA: starting to work on preparing 2018 inventories for CDC collaborative project

2. Recently posted TSDs and summaries

3. Preview of SMOKE support for MOVES3 in SMOKE 4.8

  • SMOKE 4.8 has support for MOVES3, although some of the pre/postprocessing scripts still need to be made public
  • Method to use SMOKE 4.8 for MOVES3 will be discussed on Jan MOVES MJO webinar
  • MOVES3 has been run on AWS and is being used for ORD's EQUATES project
  • Regarding the claims of NOx overestimation with MOVES, a workgroup did exist to look at this.

4. Any other emissions modeling needs / questions / collaboration?

  • Jeff V mentioned there are some udpates to BEIS in SMOKE 4.8 and associated land use and is open to collaborating with folks using MEGAN

5. Other items

  • Zac mentioned the invitation to write a paper about the Collaborative for JAWMA. Susan and Tom were interested in participating.

6. Next meting: February 10, 2PM Eastern

October 15, 2020


  1. Follow up from September webinar
  2. Modeling updates
  3. Anyone planning 2026 modeling?
  4. EPA posted 2017 platform and starting 2018 soon
  5. Any upcoming emissions modeling needs?
  6. Set day/time for next meeting - 11/11 is Veteran's Day
  7. Discussion on data sharing methods


Alison, Chad (from SESARM), Dave, Debbie, Eric, Winston, Tammy, Mark, Mary, Sara, Shawn, Tom R, Tom M, Jeff U, Jeff V, Susan, Jim B, Byeong, Winston, Jeongran


1. Follow up from September webinar

  • ERTAC package now avaialble on IWDW!
  • No other follow up items were noted

2. Modeling updates

  • Jeff V noted that he is presenting on diurnal profile updates for prescribed fires at CMAS. He thinks the new profiles are more realistic.

3. Anyone planning 2026 modeling?

  • No one besides MARAMA+northeast mentioned potential 2026 modeling

4. EPA posted 2017 platform and starting 2018 soon

5. Any upcoming emissions modeling needs to coordinate on?

  • Mark J mentioned ongoing regional haze modeling and asks if EPA would require SIPs to show that EGU shutdowns are enforcable (e.g., IPM runs include economic shutdowns)
    • If EPA does require this, it may require special runs of IPM/ERTAC EGU

6. Set day/time for next meeting - 11/11 is Veteran's Day

  • Set up meeting for 1-2 Eastern on 11/12

7. Discussion on data sharing methods

  • Shawn suggested that perhaps an FTP upload area would be helpful to supplement / complement the data request form process
  • There are some opportunities for streamlining the data request process - stratifying the componenents for the form-based downloads
    • Some data products are bigger than others and are fine to go through FTP; but when requested data amounts to multiple TB, disks are available
    • there could be a fast lane for immediately downloadable components
  • Sometimes, when people realize they want something else they fill out a new data request but could be faster to handle this another way
    • Behind the scenes, users can set up projects they associate with a platform and then when they come back they don't need to make a new full request.
  • There is room for streamlining of processing of requests. There is a person involved for any requests at this point.
    • Maybe there could be a small extension for smaller components without human interaction.
  • We agree that it would be helpful to have the uploadable area to get more data available
  • Posting of WRAP 2014v1 and 2014v2 is wrapping this up over next month.
  • Back end development was put on hold while data were stood up for release.
  • EPA willing to send the merged emissions as a test for upload system

September 10, 2020


  1. Reorganized updates to 2016v1 on FTP site
  2. Planning for September 17 National Report out call
  3. Possible data sharing updates
  4. Upcoming modeling
  5. Future collaboration opportunities


Alison, Zac, Jeff U, Jeff V, Shawn, Jeangran, Tammy, Sarah, Kevin (NY), Debbie W, Jim B, Mary, Ruby, Winston, Tom R, Jennifer


1. Updates to 2016v1: see

2. Planning for next week's meeting

  • Zac can provide a brief update (not too much new since last time)
  • Zac is interested in hearing about EPA sensitivity runs
  • Shawn will point to IWDW
  • We may want to upload recent updates to IWDW
  • Eric is almost done with an ERTAC package for 2016, 2023, and 2028 that could be uploaded to IWDW
  • Do we want survey questions after the call? (None were yet suggested)
  • MOVES call follows this next Thursday but so far no topics for this month
  • Also bridge tool training from EIAG follows this call
  • NY presentation next week will be on CMAQ modeling comparisons between IPM-based EGUs and ERTAC-based

3. Data sharing techniques

  • The IWDW tracks who downloads and what they download
  • Some modelers like a regular FTP site so they don't have to submit a request and can download what they want
  • Shawn mentioned it could be possible for him to make a more raw area of the site so that people could access data that way, thereby streamlining the process
  • Globus is an option for large file transfers in the future
  • Shawn is interested in having more data such as study outputs come back to the IWDW
  • Still need to find a good way to transfer the merged files
  • It may be possible for Alison to have more privileges to transfer data directly (need to review firewall rules to see if it would work)

4. Planned modeling

  • LADCO: redoing 2016 base and 2020 projection to support 2008 ozone NAAQS attainment demonstrations
    • A couple of corrections / adjustments were made
    • Note that while previous modeling showed almost all clean monitors, actual monitoring showed exceedances
  • LADCO also working on regional haze using a "typical base year" where some sources shut down in 2016 but reopened after are included in base and future yeras
    • Source apportionment for 2016 and 2020 will be done to understand state impacts on class 1 areas
  • LADCO also has a study running CMAQ HDDM at 4km to develop source-receptor relationships
  • EPA is digesting results from various sensitivity runs and planning where to go next
  • EPA is collaborating with CDC on a 2018 run
  • NY is implementing the corrections made in recent months into 2016 platform
  • TX is shifting to a 2019 base year for 2008 and 2015 ozone NAAQS related attainment demonstrations

5. Ideas for collaboration

  • How can we keep collaborating in the future but with less work for all?
  • EPA sharing plans is helpful
  • Compiling a wishlist of improvements that would add value is helpful
  • Maybe being more targeted about what we collaborate on
  • MARAMA is looking carefully at emissions contributions to prioritize
  • States have workforce changes that impact their throughput
  • Perhaps MJOs/modeling centers can coordinate within their regions to bring new data to the collaborative process

6. Next meeting: 12:30 Eastern, 10/15

August 12 2020


  1. Future modeling platform collaborative
  2. 2016v1 modeling activities
  3. 2016v1 platform known issues/errata
  4. September 16 or 17 national report out call with the Model Performance Evaluation Collaborative


Alison, Zac, Caroline, Debbie, Doug, Eric, Heather, Jeff U Jeff V Jennifer, Jim, Byeong, Marc, Mark, Mary, Michael, Susan, Sarah, Serpil, Shawn, Tammy, Tom M, Tom R Winston,


1. Future modeling platform collaborative

  • See background slides from Alison E
  • Weighed positives and challenges
    • Innovation of collaborative was in the process
    • We pulled more people in
    • There could have been more outside the box thinking.
  • Improvement ideas
    • Organizing and running workgroups: asynchronous collaboration, help running WGs outside of EPA, fewer WGs; transparency in data and processes
    • Manage technical improvements
  • Process vs emissions science
    • How to prioritize inventory improvements and that can help with the organization
    • FY21 EPA is working on their budgets, if we want new methods need to start thinking about pulling ideas together; timing of resources and community support will help EPA bolster resources; something that's been requested by the collaborative process; some states get more action than others
    • Example of getting the resource community involved and connecting with EPA is evident with VCPs; getting the right people engaged can help advance the process
    • TX has some research funds and they go through a process to figure out how to use these funds; internal dicussions on project ideas, people can get stumped; keeping track of potential technical improvements; develop a needs assessment document that targets areas of improvement and how these fall to funding agencies would be helpful
    • EPA is looking at new/improved ways for estimating emissions but biggest hurdle is resources for new methods, and meeting existing obligations at the same time innovation is happening
  • Selecting a non-NEI year challenged the states to participate given their obligations to the NEI process
  • The reason we have buy into this platform is because it was more transparent;
  • Can EPA provide resources to fund improvements from outside collaborators
  • EPA use of the 2016beta platform was unexpected; didn't expect this platform to be used for a regulatory modeling application; may have done things better/differently in the beta development process
    • Administrator set some deadlines that caused EPA to use these data; had the collaborative WGs known that this data would be used for RHR analyses, they would have focused on prescribed fires and int'l emissions
  • OAQPS has capacity to develop a first cut inventory, and if we could move to an EMF set up for states and locals to use it, it may be a more efficient way for others to use it
  • Next steps: Collaboration tools and a clearinghouse of ideas, discuss on next call

2. 2016v1 modeling activities

  • EPA: performance evaluation for O3; support for field study programs, fine scale modeling tied to 2016 platform (can we get Kirk to give an overview on their applications; AK/PR/HI study link); 2016beta' RH modeling; 2016alpha for O3 policy assessment; collaboration with OTAQ on backsliding study, used 2016beta (study came out in May)
  • GA: working on reproducing 2016v1 platform from EPA; will use these modeling for O3 attainment demo; will add to the platform: updated CMV emissions, airport emissions correction, and EGU correction; modelers watercooler meeting to discuss details of the SMOKE processing with the platform, e.g., afdust tool doesn't run without rebuilding shared libraries
  • LADCO: 2016v1 to 2020 projection for O3, 2016v1 to 2028 for Regional Haze, 2016v1 to 2023 for O3, 2016v1 to 2026 for O3
  • WRAP: 2016v1 to 2028 for regional haze for areas outside of the WRAP region with help from EPA and others; found some issues in the non-EGU point source inventory that they're correcting now; will reset projection inputs for Canada/Mexico and for outside of the WRAP region, will hold constant at 2016 levels
  • Northeast/NY: running through the 2016v1 platform with CMAQ for base and future year (2023 and 2028) using both ERTAC (16.0/16.1) and IPM (2016v1) options; will incorporate updates and source apportionment for 2023, fine grid over the Northeast
  • Texas: used 2016b and v1 platform hybrid for regional haze modeling; TX is moving to 2019 for the next base year; may use as a backcast year for the '08 and '15 NAAQS SIPs
  • Research studies are using this platform

3. 2016v1 platform known issues/errata

  • Known issues in 2016v1 are:
    • Airport emissions overestimated (updated inventories are posted on EPA FTP),
    • SMOKE processing dropped some CEMS data in base and future years - new inventories on EPA FTP are available to address both issues and upcoming SMOKE 4.8 expected to prevent these drops in the future
    • CMV inventories had minor adjustments (corrections were posted on EPA FTP in Jan/Feb, 2020)
  • New emissions since 2016v1:
    • IPM EGU inventories Jan 2020 version
    • ERTAC inventories also updated

4. September 16 or 17 national report out call with the Model Performance Evaluation Collaborative

  • Will have quarterly report out on September 17 at noon Eastern
  • EPA , NY, and LADCO will report on 2016 modeling; looking for others to participate as well
  • Susan to send out webinar invite

June 10, 2020


  1.        2016v1 platform updates
  2.        Transfer of merged data to IWDW
  3.        Discussion on the next steps for the Collaborative; a few prompt questions for the discussion
    1.        Discuss the transition from the Collaborative to other types of collaboration; what’s going on already and what are the priority areas that need attention?
    2.        Short of a full effort as was done for the 2016 platform, what role can the emissions collaborative approach play in the NEI-based platform development process?
    3. What would a more efficient EMP development process look like?
    4. What were the primary successes/benefits of the Collaborative and how do we build off these moving forward?
    5. Next steps…at what point do we slow the frequency of meetings? How do we document the process, journal article?


Alison, Zac, Caroline, Jeff V, Tom M, Susan, Sarah, Debbie, Byeong, Mark, Tammy, Serpil, Jeff U, Chungyang, Winston, Jim, Mary, John, Doug, Erc, Tom R


1. 2016 Updates

  • EPA to work with IWDW to determine best way to transfer merged emissions when offices are closed
  • Airport emissions are overstated in 2017 NEI and 2016 platform inventories. Impacts vary by airpirt they they are up to two times too high at large airports.
  • EPA will generate updated inventories for 2016, 2023, and 2028 after the updated 2017 is available mid-June. EPA is not sure whether they will model with the new emissions in the near future.
  • ERTAC is working on the future year platforms - 2028 is almost done and 2023 is being worked on. Will package these and send to IWDW once ready.
  • LADCO found some large mining-related sources didn't operate in 2016 but have since then and should be included in future projections. They are working on folding these sources in to the inventories.
  • These updates will be described and linked to the Platform Updates Wiki page once avaialble
  • NY has run 2017 through SMOKE and is doing some modeling with CMAQ
  • Tom M mentioned the difficulty in projecting coal EGUs into the future as they are becoming less utilized for base load operations (disuss further at upcoming EGU call)
  • Note that temporal profiles from the base year are preserved in both IPM and ERTAC modeling

2. Next steps for the Collaborative

  • The Collaborative has been a lot of work, but there have been a lot of benefits
  • We should work to agree on the next steps
    • We may want to splinter off some smaller groups or plug more into other independent workgroups
    • Are there workgroups that don't exist that would be desirable/needed?
  • Can we bring modeling platform concepts into NEI development?
    • What kind of review might be appropriate if we do this?
  • Can we work towards base year modeling platforms for every year?
  • Jeff U mentioned the Collaborative was a very helpful and good alternative to each MJO making its own modeling platform - we saved resources and improved consistency
  • Tom points out that we need to pay attention to competing efforts for state resources like the NEI (or could the two be merged somehow?)
  • Tom R liked the NODA process to notify states that data would be used for rulemakings and the collaborative work that resulted from these
  • CAMD has been proactive at making their model results available in ways not tied to rulemakings in recent years
  • Tom M points out that EPA products are taxpayer funded and should be public and wonders if NEI process could be improved and less informal

3. We are thinking a National outreach call would make sense late summer

4. Zac wonders if we want to write about the process in a journal article

5. We decided the next meeting would be August 12

May 13, 2020

  1. Discussion on the future of Collaborative emissions platform development and next steps for the Collaborative; see attached slides from Tom Richardson and Tom Moore
  2. Review survey from the April outreach call
  3. Distributing the 2016v1 CAMx and CMAQ-ready emissions


Alison, Caroline, Tom R, Tammy, Sarah, Eric, Michael, Chungyang (NY), Mary, Jeff U, Doug, Winston, Ruby (NY), Zac, Tom M, Susan, Jeff V, Jim B, Serpil, Debbie, Norm, Mark, Serpil

Notes Distributing the 2016v1 CAMx and CMAQ-ready emissions

  • How do address requests for merged, model-ready emissions
  • Do we include IPM or ERTAC? BEIS or MEGAN?
  • EPA can make 2016v1 "EPA Platform" merged emissions to the IWDW; these include IPM
  • The IWDW can host the merged files; EPA will coordinate with CIRA staff to test an electronic transfer to IWDW; may need to wait until hard drives can be written (EPA doesn't have access to their building right now);
  • Need to add metadata so that if people are to download these, what the configuration is in the files
  • Track the configuration planned for by modelers
  • Note that ERTAC base year emissions are slightly different from IPM-based, so multiple versions of merged emissions would be needed.

Review of report out call survey

  • Alison reviewed the responses and will send to the group
  • If we have another report out call, we could invite all who downloaded the platform - including researchers and contractors

Discussion on the future of Collaborative

  • Tom M and Tom R presented thoughts on 2016 platform and beyond
  • How to memorialize lessons learned?
  • Can we accomplish more (or same) with less effort?
  • Was this a one-time proof of concept?
  • EPA is working towards annual base year inventories and platforms
  • How useful will 2020 be as a national inventory, and/or modeling platform
    • If it has research applications only, what are the hypotheses
  • Can the NEI by more automated? What does a hybrid collaborative-NEI effort look like?
  • Does the Collaborative process obviate the NODA process?
    • NODA is typically tied to rulemaking, and don't always have a lot of notice to prepare
    • EPA would still have to take comment on data for rulemaking, irrespective of the process to generate those data
    • States shouldn't be surprised if the collaborative data are used for future rulemaking

Review results from last quarterly call (attached)

  • Projection years: some post 2028, 2020/2021 (ozone), 2026 would be a new attainment date for 2015 O3 after bump ups, as would 2008 O3 NAAQS bump ups; areas that are marginal going to moderate goes to 2024 (2023 modeling) and if don't make that would then be 2026; 2008 serious attainment date is 2021, so their bump up is 2026
  • Plan to summarize for April 29 call

April 29 Call Agenda

  • Emissions updates since v1 release, what's come since the last call
  • IWDW Update - Platform status and summary of requests, update slides from last call
    • Platform Known Issues and wiki

    • LADCO: preliminary model performance evaluation from AMET for O3 and
    • WRAP: Regional Haze results
    • EPA: modeling plan and modeling results
    • Questions at end

  • Regional haze projections in SMAT and AMET do not have updated data for projecting; data are updates are needed for both

Presentation template and deadline

  • Use wide-format for template

Will there be another quarterly call?

  • Some would like to see another call scheduled and see what results become available (cancel if nothing useful)
  • We can ask people if they find value in another one
  • EPA is still early in the plan on the evaluation and will have more to show in a few months; others likely will too
  • Also there is overlap with the MPE group - Zac and Alison to coordinate with Heather

Is EPA doing Future Year Modeling?

  • Yes, EPA is working on 2023 and 2028 modeling

2020 as an Inventory/Modeling year

  • 2020 will be an atypical year, how much value will it be for a base year?
  • Still, the AERR requires that inputs to the triennial inventory be provided
  • Concerns about the representativeness and how it will look in trends
  • Is this collaborative going to help reinvent the NEI process to be more representative of modeling; try to not get hemmed into NEI process
  • For 2016, there was less robust state participation by some states because states had to invest time in both efforts; what should the states be putting their time/effort into right now?
  • This could be a good topic for Fed/State workgroup call (Mary, Norm)

March 18, 2020

Next call: April 8


  1.        IWDW update (requests, what is posted, what's left to do)
  2.        ERTAC v16.1 release and update
  3.        New data becoming available for use with 2016v1 platform: CMV, WRAP oil and gas, ERTAC base year - getting to IWDW
  4.        2016v1 modeling updates from EPA and others
  5.        Updates to 2016v1 documentation (EPA, LADCO)
  6.        Next large group meeting is scheduled for April 29, 2020 at noon Eastern - who can present on 2016v1 platform modeling and analysis results?


Alison, Eric, Tammy, Tom R, Debbie, Susan M, Mary, Shawn, John, Byeong, Sarah, Michael, Serpil, Jim B, Caroline, Tom M, Mark J, Jeff U


IWDW update (requests, what is posted, what's left to do):

  • Still have a couple of items not yet transferred - downloads are slow - EF tables and scripts + ancillary data

  • Alison to point Shawn to remaining files

ERTAC v16.1 release and update

  • ERTAC just finished updating the future year files - and a correction to base year (2020, 2023, 2028)

  • Probably want to wait to put them all together with base year

New data becoming available for use with 2016v1 platform:

  • CMV, WRAP oil and gas, ERTAC base and future year - need to get these to IWDW

  • WRAP oil and gas - can provide a package that runs through SMOKE within next couple of weeks
    • Jeff to report out on the work done on WRAP SMOKE files in April (and on quarterly update?)

  • Mexico 2016 point inventory - hope to be able to share soon, and provide nonpoint and mobile data in SMOKE-ready format. WRAP interested in seeing it. Municipio and state-level summaries are available.

2016v1 modeling updates

  • EPA completed runs with CMAQ and CAMx - hope to share results soon. Some future year runs coming up - schedule TBD

  • LADCO Got AWS to run WRF for 12k and 4k midwest and some 1.3k grids - big success and worked on lower cost compute nodes; working on wrapping up the 2016v1 photochemical modeling and will start 2020. Will interpolate the CAMx files for most sectors for 2020 (4 parts 2016, 3 parts 2023)

  • LADCO wrote an R program to interpolate the point sources to get to 2020 - sometimes interesting values come out of that. Working with states on their non-EGU point sources and adjusting as needed. Once 2020 is done, will move on to 2028 with the new ERTAC runs.

  • OTC is hoping to do some tagged modeling and possibly some 2026 modeling (bump up year for ozone)

  • NY put together the premerged emissions and ran CMAQ for 36 and 12km grids along with 2023; will fold in ERTAC next; looking to do some source apportionment (working on a design that would do a bit of state + sector source apportionment) and eventually 4km

Updates to 2016v1 documentation (EPA, LADCO)

  • Updates to most sectors have been posted on Wiki page; working on rail; expect update to ERTAC for future years

Next large group webinar is scheduled for April 29, 2020 at noon Eastern - who can present on 2016v1 platform modeling and analysis results?

  • WRAP oil and gas update
  • NY might have some things to show
  • LADCO may have something to show
  • EPA may have modeling results - model performance, etc.
  • Possibly update on Mexico and new EGU inventories
  • 2017 nonpoint wrapping up - will rerun wagon wheel at end of March and redo selection first week of April. Sent worksheets around for states to review - planning on release end of April.
  • Survey after last quarterly call - alternative future years were asked about - may want to discuss again

Alernative times for next coordination and modeling meetings

  • Next coordination: 1:00 Eastern on 4/8
  • Modeling: Maybe 31st or 1st at 1:00 Eastern?

February 12, 2020


  1.        New data becoming available for use with 2016v1 platform: CMV, ERTAC, WRAP oil and gas
  2.        Data distribution updates from IWDW and EPA (what is posted and where, what’s left to do)
  3.        2016v1 modeling updates from EPA and others
  4.        Updates to 2016v1 documentation (EPA, LADCO)
  5.        Next large group meeting is scheduled for April 29, 2020 at noon Eastern
  6.        Other topics?


Alison, Tom R, Eric, Tammy, Alison, Jeff V, Alex (NESCAUM), Susan, Mary, Sarah, Tom M., Shawn, Serpil, Mark, Jeff U


1.       New data becoming available for use with 2016v1 platform: CMV, ERTAC, WRAP oil and gas, Mexico point

  • CMV: base and future year data available on EPA FTP site (see 2016, 2023, and 2028 directories, scripts also updated; still need to post non-CONUS). Note that summaries still need to be updated.

  • ERTAC: Need to post 2016 - note that there is a sector ptnonertac. Will have 16.1 data running soon. Note that there are some different units from EPA's approach - there is a daily file for non-EGUs. Don't have ptnonertac sector for future years yet. Should be available sometime in March. There would be a new ERTAC comment period in August. IPM shuts down aluminum foundries (not in future year inventories any more). They will send the list of sources they don't think should be shut down (EGUs by IPMs definition). Future years should be available with latest shutdowns by March.

  • WRAP oil and gas: EPA has base year data and ancillary data; future year data still needs an update - should be very soon. EPA working on running through SMOKE and will share those when ready.

  • Mexico point inventory - hope to have this soon - need to check with Mexico; will then turn towards nonpoint, onroad, etc.

2.       Data distribution updates from IWDW and EPA (what is posted and where, what’s left to do)

  • EPA and IWDW will coordinate on the remaining pieces - just need to iron out a few details to get the data posted

  • Shawn will send new request spreadsheet soon

3.       2016v1 modeling updates from EPA and others

  • EPA has run the base year 2016fh with CMAQ and CAMx at 36 and 12km; now working on sensitivity runs to firm up model configurations. Sensitivities examining: vertical mixing schemes, ammonia deposition schemes (including “bidi”), treating all point source emissions as elevated point sources (w/plume rise), adding lightning NOx, and adding natural windblown dust emissions. Once the sensitivity results are analyzed, EPA will select preferred configurations for future runs. Note that EPA used CAMx version 7, beta 6; official v7 release is expected in March.

  • Jeff will check to see if EPA will do some sensitivities related to the WRAP oil and gas EI* LADCO running 2028, 2023, and 2020

  • CRC project is supporting fine scale regions and source groups - idea is to use the tool to renumber the source groups to allow finer information for source apportionment

4.       Updates to 2016v1 documentation (EPA, LADCO)

  • Alison still has some updates to do (e.g., onroad)

  • Rail group is working on the rail documentation

  • ERTAC specification sheet was finished for base year

  • Tom still needs to review Canada and Mexico docs

5.       Review of survey reports from last large group call (see attached).

  • about 25 responses received - they were sent out with the last email on this call today

  • Tom M noted that there were more eastern states than western on the outreach call

  • Tom M suggested that there could be some additional responses that could be solicited - consider states that don't work as closely with emissions. We should consider how those states could be more engaged in future efforts. Tom suggests more outreach is needed.

  • Mark mentioned that different regions perform emissions planning / modeling in different ways. It's good to have discussions on how different problems could be solved (e.g., sources not running in 2016 that are online in 2017 and later year). States need various types of assistance along the way to successfully use and build the platform.

6.       Next large group meeting is scheduled for April 29, 2020 at noon Eastern

  • Tom R: situations that might reconsistitute the collaborative would be a good topic for discussion

  • Will April be the last call? We should decide this on the April coordination call. Note it's easier to cancel a call than to schedule one later.

7.       Other topics

  • Alison to check to see if there were other data requests

January 8 , 2020


  1. Data distribution updates from IWDW and EPA
  2. 2016v1 modeling updates from EPA and others
  3. Documentation status for v1
  4. January report-out call planning

Attendees Debbie, Sarah, Mary, Tom M., Caroline, Zac, Mark, Eric, Tom R., Michael, John H., Jeff U., Jeff V, Alison, Zac, Serpil, Tammy, Susan, Mary


Data distribution updates from IWDW and EPA

  • IWDW has been servicing some data requests for the v1 platform, but only the components from the beta platform
  • Target the outreach call in two weeks to have more of the v1 platform available
  • EPA loaded future year emissions on a drive and sent to NY
  • IWDW sent NY a drive with base year emissions, and NY sent along to VA
  • EPA has the inventory input data and plots out on their ftp site
  • Pending requests from MN and GA for the external drives
  • Shawn to provide slides for the report out call on IWDW

2016v1 modeling updates from EPA and others

  • CMV: EPA is updating the CMV emissions to correct an error in hotelling (C3) and to temporalize the emissions to 2016 days-of-the-week; updated inventories and reports reflecting the CMV updates are on the EPA ftp site; future year CMV data have not yet been updated
  • Goal with modeling is to get a sense for how the platform data look for model performance
  • Future Years: all sectors have been processed through SMOKE, but no air quality modeling has been done with v1 yet (and no schedule for this)
  • LADCO is processing emissions to our grids now; questions about the CAMx version LADCO will use

Documentation status for v1

  • Spec sheets have mostly been reviewed
  • Non-point sector review is being worked on by MARAMA, trying to get comments back in the next week
  • EPA is working on incorporating comments on draft spec sheets and finalizing by the report out call
  • Draft rail spec sheet is targeting to be done by the report out call
  • ERTAC EGU spec sheet is close to being finished
  • Send comments on CMV to EPA

January 23 report out call planning

  • Summarize v1 vs beta: plots and narrative description of changes
  • Sector WG presentations
    • Describe major changes from beta, feedback received on beta and how it was incorporated, any outstanding issues
  • Air Resources Board and other collaborations
  • Distribution discussion
    • Tentative presentation by IWDW, check in on Jan 8 call
    • What's available now and how to get it
  • How to submit feedback on v1
  • Wrap up the collaborative in its current form
    • Milestones, things that we may want to revisit components of the platform; talk about how to major component releases could set up a time frame to revisit the modeling platform
    • EGU workgroup will continue to work on ideas and news, not just ERTAC
    • High level dates/milestones that EPA is looking at for the 2017NEI, e.g., when the first 2017 platform is released, will that be a point at which we come back and do analysis to compare to 2016 platform; EPA can talk about the NEI schedule, but don't really have enough information to discuss the next NEI-based modeling platform
  • Zac to send slide template out by Friday 1/10 end of day; looking to get slides back from WG co-leads by Tuesday 1/21
  • Feedback from regional contacts on regional haze modeling that may not have the most up-dated EGU forecasts; could be get feedback on expectations for 2016v1 platform and whether the EGU forecasts are reliable, how acceptable is this platform and whether it is feasible for use with transport, regional haze, ozone planning, etc.;
  • Do we need to develop a process on the questions to be asked before moving to a new platform? What questions do we need people to weigh in on, through a transparent process

  • Survey questions (up to 5 polls with multiple questions)
  • Where are things headed in the future?; what are the regulatory issues that are on your radar?
  • What base years do you want to see for a future EMP? Base years to avoid?
  • How should the collaborative exist moving forward? What role will it have moving forward as new versions of EGUs, MOVES, etc. are released

  • Possible next webinar April 29-30

December 11, 2019

Next call: January 8


  1.        Data distribution updates from IWDW
  2.        Documentation status for v1
  3.        v1 data/modeling updates from EPA
  4.        January report out call planning
  5.        Post-v1 release discussion


John H, Debbie, Tom R, Zac, Alison, Mary, Caroline, Eric, Tom M, Jeff U, Sarah, Heather, Jim B, Tammy, Susan


Data distribution updates from IWDW

  • Filled 15 data transfer requests for beta platform since Nov (2 state, 2 MJOs, 11 Universities)
  • Some of the universities working for states
  • Variety of modeling experience and types of studies
  • Most transfers emissions, some met and ICBC
  • Some going out as ftp
  • working on v1 at IWDW, questions about pre-merged emissions; what should the plan be to provide these to outstanding requests in the next month or so?
    • challenge is it’s a large volume of data, and there needs to be mapping between the data disks and warehouse;
    • NY to send drive to EPA for getting the files; NY seeking base year, but will also take the future years
    • IWDW will keep their drives and continue to populate the warehouse

Documentation status for v1

  • Rail and ERTAC EGU documentation is outstanding; rail is with Mark
  • ERTAC EGU is almost done, should be ready before the holidays; will send final version when it’s ready
  • EPA is reviewing the comments that they’ve received back
  • Canada/Mexico and CMV are still pending review
  • For latest version of CMV files, look in the 2017 NEI documentation or the v1 release page for spec sheets
  • MARAMA seeking most up to date version of the CMV and non point spec sheets
  • LADCO reviewing CMV, rail, and point IPM

v1 data/modeling updates from EPA

  • EPA has been modeling emissions data for CMAQ (12US1) and CAMx (36 and 12US2); anomalies in CMV C3 data in a few locations, hoteling caused the hourly emissions to be too high in a few areas; will provide a summary that describes where the hoteling issues occurred.
  • CMV: when changed 2017 to 2016 decided not to preserve day-of-week, but because of day of week signatures in some areas, will preserve the day of week profiles; working on this mapping now, may impact fine scale modeling and episodic ozone runs
  • Gridding of data for spatial source apportionment for fine scale runs, centroid of a grid is used as the county, and could create a misapportionment of the emissions; working on a method to improve the attribution for CMV (currently based on county that holds the center of the grid cell); will create a new emissions data set to improve this feature
  • Haven’t noticed issues with other sectors
  • LADCO looking at gridded emissions plots and profiles now
    • working on processing now - for ag - found patchiness in emissions (small counties)
    • some counties have emissions while others don't - LADCO 4km ag NH3 plot shows spatial discontinuity
    • Zac will do the profile plots soon - temporal, speciation, spatial
    • broke nonpt and nonroad into subsectors (e.g., solvent, ind, waste, etc; diesel, the rest)
  • EPA hopes to do model runs over the holidays for review in early January (also working on Mexico)

January report out call planning

  • What to present?
    • Help to orient people to the plots, and where they can find more: stacked bars, spatial plots, profile plots
    • Show people how to get to the plots, for more info, where to go (IWDW, LADCO, EPA ftp)
    • Distribution methods
    • Big changes based on feedback between beta and v1
    • Tentative presentation by IWDW, check in on Jan 8 call
    • Wrap up the collaborative
    • Air Resources Board collaboration, highlight the changes
    • Future projections, and that some rules will change; proposals for rules and how those may impact the modeling; until something is finalize can’t include in the inventories
  • EPA says people are making helpful observations, and making comments about the data

Post-v1 release discussion

  • Work to integrate the western 7 state oil and gas inventory
  • Usability and differences in Mexico inventory, need to understand the Canadian inventory
  • ERTAC EGU integration
  • EPA to analyze emissions for large point sources near the US border
  • What’s the next base year? It still remains to be seen
  • For 2017 EPA has some modeling work to be done, field studies in 2017-19 that can be used to evaluate the inventories; non-regulatory, research motivations for modeling these years
  • WESTAR/WRAP drafted state comments on the process; there may be things that we consider doing differently next time (e.g., asking people what they need and when); what kind of national modeling does EPA think is needed given the status of rules; flipping it around, ask the MJOs and members what they would benefit from (e..g, different scales of modeling, and sectors to focus on);
  • What’s the base year? NAAQS based, which sectors need to be updated every year? Can we get met for every year and only replace some sectors;
  • There are more and more reasons to model every year; how much time and effort to creating inventories for each year; creating projections is a big lift and needs a specific base year.

Zac, Alison, John, Eric, Jeff V, Tom R, Debbie, Susan, Mary, Caroline, Julie, Sarah, Tom M, Jeff U, Tammy, Jim, Serpil


       Status of the v1 release: recent updates and outstanding issues

  • EPA posted this week a new all-in-one package: entire 2016 inputs and scripts (8 Gb), 2023 and 2028 add-ons (minus MOVES EF tables)
  • Reports have been added along the way with the data/scripts packages
  • WRAP oil and gas emissions data are still outstanding
  • Country report to be posted
  • A lot of data/reports are on
  • ERTAC EGU/non-EGU, working through IPM/non-IPM splits from EPA to create point ERTAC and point non-ERTAC files; still testing but can distribute sooner, as needed; will include both base and future year ERTAC/non-ERTAC inventories
  • 2016 marine files for finer grid domains are processed for the LADCO 4km and 1.33 km domains; and Long Island Sound domains

       Documentation status for v1: pending documents and reviews

  • MEGAN - no need to review
  • BEIS - NY (Completed)
  • Onroad - LADCO (Completed)
  • Rail - documentation in process by LADCO (for review by MI)
  • Nonroad - NY (Completed)
  • C1/C2 & C3 - LADCO
  • RWC - NY (Completed)
  • nonpoint - ready for review by MARAMA

    • Carried forward much of the information from beta, will work through the page and get it live soon
  • LADCO image viewer for v1
    • County bar plots
    • National/regional/state stacked bar plots
    • 36 and 12km gridded emissions maps by sector
    • Need to create profile plots

       Quick roundtable summary of planned v1 uses / modeling

  • EPA
    • Have not merged the emissions yet because they're trying to figure out if they're going to use 1- or 2-way nesting for CAMx; new chemical mechanism in CMAQ will require different speciation (new BEIS run), also don't need to merge all of the sectors to support new features in CMAQv5.3
    • Will first do model performance evaluation
    • Heavy duty NOx modeling
    • Will run 12, 4, 1.33km domains for 2016
    • Will do a summer season 2020 projection for 2008 O3 NAAQS
    • 2028 annual run for regional haze (12 and 4km only)
    • 2023 summer season run for 2015 O3 NAAQS
    • Changing the source apportionment tagging, adding county groups and altering sector groups for flexibility in the air quality modeling

December Call

Will hold the call and devote much of the agenda to talk about what to present on the January national report out call

       Post-v1 release: straw proposal on conditions which could result in a "2016v2"

  • Sources that will become available to include with the platform: ERTAC EGU 16.2, WRAP oil and gas inventory
  • EPA analysis of beta vs v1
  • EPA received emissions data from Mexico, these may need to be included
  • Could a new version be targeted at a new MOVES onroad release
  • MARAMA is looking at 2026 for a modeling year because of 2015 O3 NAAQS bump ups; EPA suggests that this could be a projection off of NEI2017
    • 2026 needed to model 2015 O3 NAAQS serious attainment (attainment date is summer 2027)
  • Would the 2017 platform be built collaboratively?
    • EPA hasn't thought through this
    • EPA has internal applications for base 2017
    • No discussion yet on projections
    • What will the 2017 platform be suitable for? e.g., O3 in the west?
  • Conditions that could require a new platform version
    • Major issues found in v1 data: what is a major issue? which sectors/pollutants?
    • Updates to a critical number of sectors: what's the critical number/which sectors?
    • EPA rule-making modeling -> NODA process; or is this an entirely new branch
  • What could go into v2?

  •        Status of the v1 release (15 min)
    •        What are the outstanding sectors/issues and what’s the timing to resolve
      • IWDW Wiki and EPA web pages set up:
      • All SMOKE inputs and scripts for 2016 base year are available (except WRAP oil and gas):
      • Inventory zips for 2023 and 2028 are available

      • SMOKE outputs for 2016 base year are available (premerged)
      • SMOKE outputs for 2023 and 2028 available for onroad and nonroad (for 2028 only)
      • Scripts and remaining SMOKE outputs for 2023 and 2028 to be developed during October
      • WRAP oil and gas inventory still needs to be evaluated / configured
      • ERTAC platform is being developed: working on processing scripts now, and splitting EGU/non-EGU sources; will be packaged together for an easy and complete swap for the IPM point source package; working to have 2016 ready by late October/early November, and future year (2020, 2023, 2028) available mid-November
    •        What has been transferred to the IWDW for posting/release?
      • Drive sent with premerged 2016 base year SMOKE outputs and available outputs for 2023 and 2028
      • FTP site set up for transfer with full sets of MOVES emission factor tables
      • IWDW review, working on transferring all of the data now; will need to work with EPA to show redundant components between 2016beta, 2016 Regional Haze, and 2016v1;
    •        Release package contents
    •        Documentation status
      • Drafts of most spec. sheets have been developed - need to fold in tables at the end; EPA will add in tables and plots and make Word docs available later this week on the Google Drive; PDFs will get linked into the Wiki
      • Reviews by the modeling workgroup, and then update to the spec sheets by the end of the month

    •        Should we survey the broader community to get outside perspectives on the Collaborative process?
    • EPA realizes that there are sectors that will continue to evolve, workgroups working on some sectors; don't have a big picture answer on EPA involvement, will be turning attention to 2017 after this is done; will have 2016 modeling going on for a while by EPA and other groups, as the modeling goes forward, expect issues will arise that may need to be addressed; looking for ideas about how to keep EPA engaged in the process
    • Is there an activity when there is 2016v1 modeling, if that could be the focus for this group
    • For EPA's EGU participation, will continue to work on the sector to address demand projections, production changes; it's a never ending update; the EGU workgroup pre-dated this Collaborative, but will check in periodically;
    • Go back into pre-existing workgroups, and then only gather the Collaborative WGs periodically
    • NODA process together data for regulatory purposes; absent this need, is there a similar or parallel process to bring together this group in a similar manner; how to bring the parallel steps together into a new platform?
    • Zac to develop a straw proposal with a list of criteria that could bring together the Collaborative to create a v2 platform; discuss on the next call

September 11, 2019


  1. Review action items
  2. Review noteworthy developments since the last call
  3. Confirm plans for 2016v1 release: When, What, Where, Documentation, Notifying interested parties
  4. Plan for Quarterly update call on Thursday 9/26 12 Eastern

Action Items


Review August Action Items

  • WG Co-leads: Update the timing on the 2016 Collaborative Inventory Tracking Spreadsheet Alison took a first shot at this - please review / edit as needed.
  • Jeff looked at the spreadsheet, does any have any questions about what's in there?
  • Most of the 2016 items finished in August; small redo of nonroad and C1C2 are not ready yet (found an error in the first round of v1 processing)

Review noteworthy developments since the last call

  • Summaries: EPA provided summaries to the modeling workgroup that include 2016fh (v1) emissions numbers. In addition, summaries are available by "profile type" - speciation, temporal, and spatial upon request.
    • LADCO will plot these when the C1C2 emissions are redone

  • Early SMOKE input/scripts release for 2016: EPA provided an early release of inputs and scripts for 2016 - see Data Repository / 2016v1 / SMOKE input package
    • LADCO downloaded the scripts and are starting to apply to the LADCO modeling grids

  • More items: per discussion
    • Modeling WG volunteers are ready to review the spec sheets before they go public; Zac will connect Modeling WG volunteers with sector WG spec sheet authors; anticipate 1 week of review/editing before public release of documentation
    • EGU WG working on identifying split EGU/non-EGU between ERTAC and IPM
    • Will have two spec sheets for ERTAC and IPM spec sheets for v1, as with beta
    • 2023 and 2028 onroad emissions have been computed

Confirm plans for 2016v1 release

  • When: A number of requests for the platform have been made by various stakeholders. Tuesday, October 1 is the targeted release date.
    • For alternatives, such as ERTAC EGU, do we package and distribute separately or in the v1 release package? Would like to include ERTAC in the v1 release

  • What: Initially, the 2016v1 release will include inventories and other inputs to SMOKE for 2016, 2023, and 2028; plus SMOKE outputs (aka "premerged emissions") for each sector for the year 2016 and for certain 2028 sectors. Fully merged AQM-ready CMAQ and CAMx emissions will not be available by the initial release date because they won't have been developed by the time of the release.
    • When will model-ready files be ready? EPA doesn't know when the modeling files will be ready
    • What's the timeframe for the transfer? Will be phased in v1; initial set will be inputs and inventories that can be transferred electronically (ftp) in early Oct timeframe; as other pieces become available, they can be transferred by external drive
    • Working toward new 2016 base-year O&G data release from O&G WG; EPA split states into separate files to accommodate integration with the v1 platform; should this be integrated with the v1 oil and gas platform? Targeting October 8 for projection data; integration with the base platform O&G data should involve a swap out by state/county, no need for point reconciliation
    • Won't have SMOKE outputs in early October (pre- or fully-merged), those will come later
    • Need to be clear in the quarterly report out call about what will/will not be in the early October release
    • If EPA provides pre-merged data, modelers can put those together, as needed

  • Where: The data will be available on the Intermountain West Data Warehouse.

  • Documentation:
    • A landing page for the release will be available on the Wiki as was done for beta.
    • Draft documentation in the form of specification sheets will be available by the release date.
    • Some edits to the documentation may continue after the release and spec sheets updated as needed.
    • Spec sheets should include a discussion of comments on beta and any incorporated improvements.
    • Q: how can we accept comments / questions on the documentation and data? Sector groups should handle this by sector; we should continue to use the CMAS forum

  • Notification: All coordination group members will be notified, along with all registrants who have attended the quarterly update webinars. [Does anyone remember how we did this for beta?] The timing of the release will also be previewed on the September quarterly update call.

Planning for Quarterly update call on Thursday 9/26 @ 12 Eastern

  • Targeted items on slides: Describe what you've been working on, what's included in v1, what's different from beta

  • Collation: Alison will be doing the collation this time - please have your slides to her by COB Monday, September 23.

  • Finalizing: Alison will update page for the call prior to the call

  • Tee up another quarterly call in December/January to discuss post-v1

Discussion on integration of alternative inventory components

  • We started a discussion last time about how to handle sectors with alternative inventory components in the release and analysis products
  • Affected sectors: Biogenics, EGUs (overflows to non-EGUs), point and nonpoint oil and gas
  • If people want to use the alternatives for these sectors, how will they know how to do it? Have all data been provided to IWDW? [MEGAN - yes]

What happens Post v1?

  • Should we schedule a meeting in October? Note: The usual 2nd Wednesday at 2PM overlaps the MOVES review WG - would people be available at on 10/9 at 3, or Thursday 10/10 at 2 or later? Settled on 3PM 10/9/19
  • How to handle version control, documenting errata, etc.
  • We expect some updates (e.g., a new inventory for Mexico) may become available in the months following the release.
  • AQM-ready emissions files may become available
  • Develop a survey on what the community thinks the collaborative should be doing moving forward
  • Is there a plan to compare with the 2017 NEI? We can create plots with the 2017 base emissions included in the 2011, 2014, 2016 analyses
  • Talk about post-release plans for the Collaborative; what are our plans post-v1
  • Are we having more quarterly updates? The committee thought yes. Alison proposed we have one in January instead of December since it woudl be right before the holidays. After some follow up via email we settled on 1/23/20 at noon Eastern.

WG roundtable, report on new/notable developments

  • Nonpoint : base year is finalized, includes new ag livestock 2017 headcounts; removed emissions for states from deer, cats, dogs, and human perspiration;
  • NonIPM Point : base year is finalized, including closures and changes from beta, MARAMA growth packets, NJ source removed for 2016 that didn't report emissions; airports/aircraft now a separate processing sector
  • Biogenics : 2016v1 emissions are ready, including with Canadian BELD data; models run for summer 2013 and being used to compare to isoprene emissions flux data; evaluation will continue moving forward
  • EGU : nothing new to report from IPM posted in June (May 2019 version), will include documentation on post-processing IPM PM emissions; ERTAC runs are complete, LADCO will provide a data package for 2016, 2020, 2023, and 2028; trying to work with CAMD on creating more consistency between IPM and ERTAC source definitions (e.g., EGU vs non-EGU); request out to states to collect current information on sources for next ERTAC run later this year
  • Fires: Inventories are ready; cleaned up double counting, new spp profile, integrated new databases, hourly-specific rx fire data provided by GA;
  • Canada/Mexico: No updates (excluded windblown dust and construction dust in Canada)
  • Marine: EPA finalizing work in the inventory (2017); developed methods to process hourly emissions in SMOKE and grid to different modeling domains
  • Oil&Gas: nonpoint 2016 PA, IL updates are included in V1, waiting on data from WRAP (7 states) next week; plan is for platform to have option to use the WRAP inventory or the Oil and Gas Tool inventory; future year nonpoint still being compiled, ready in mid-September, WRAP will provide 7-state inventory; point 2016 no changes outside of the WRAP region, WRAP updates ready in the next week; future year point working on growing transmission (pipeline) emissions; WRAP will provide future year scenarios in September (and maybe CARB); will include default option and WRAP-provided option for oil and gas sources; work happening on flaring emissions in the Williston basin (200% under estimated in the current inventory)
  • Nonroad: late June finished 2016 base year, swapped out CA and TX; finished 2028 and 2023; will be reviewing results next week
  • Onroad: 2016 MOVES run completed in July, SMOKE-MOVES done in the last two weeks, using new features in SMOKE-MOVES; data processing are done, review in the national MOVES WG next week; will be starting 2023, 2028, and 2020 MOVES runs in the next week; considering updating the activity data using 2019 AEO data; with CO adopting zero emission vehicle program it's not currently reflected in the modeling, need to talk between CO and EPA
  • Rail: 2017 documentation done on Monday, projections and base inventories are finished; working with EPA contractor on possible issues in the projection data

V1 release update

  • EPA rolling out V1 components, includes 2016 data other than onroad and CMV; doesn't include scripts

WG roundtable, report on new/notable developments

  • Nonpoint : received final livestock numbers, will use these (based on 2017 NEI because large underestimation of dairy cows, poultry) for 2016; apply updates based on comments
  • NonIPM Point : airport data received and separated into new sector; removing HAPs to send to WG/states to review
  • Biogenics : TCEQ finished June/July 2013 MEGAN runs, EPA working on BEIS, looking to compare to the SEAS isoprene/monoterpene results
  • EGU : EPA posted IPM updated reference case (May 2019) in June and flat files are ready for modeling 2023 and 2028 (has NEEDS data for 2020, if needed); ERTAC completed v1 emissions, will not be folding western data into this case, but starting on ERTAC 16.1 to be completed in January 2020, looking to include western data there

V1 Release logistics discussion: what to put where, documentation

  • Create a timeline for the overall release, put under the v1 platform wiki
  • WG co-leads update timing on inventory tracking spreadsheet
  • Make sure the v1 spec sheets are being developed off of the beta documentation that includes future year information (distributed by Alison)
  • Will there be a release of the beta future year inventories?
    • No, but EPA has created a beta-prime that they're using for 2028 visibility modeling
    • Suggest asking OAQPS (Chet) what they think about using the beta prime (or a derivative of beta for policy application work): see Brian Timin's presentation from federal-state call
    • Tom: should be a release of the EPA beta-prime data to see what they're using for their haze modeling
    • Need a broader understanding of the changes from beta in beta-prime
    • Zac: follow up with OAQPS on what makes beta usable for policy applications

Post-V1 release thoughts

  • Julie: Inventories are continually being improved, and have an opportunity to do this with this platform; each platform is a stand alone item with a constituency behind it; e.g., EGUs will be continually improved through ERTAC; how do we continue to prop up the inventories through time; lower level of effort, but ongoing care and feeding; keep a list of people available and only start up WG, as needed; but need for at least one person to represent each sector
  • Tom: what about work that we know about coming out of 2017NEI, can people at OAQPS continue work on 2017 and turn it into modeling platform; what's the shelf life of this platform?
    • No decision yet on what the next platform will be; several updates from 2017 NEI that went into the 2016 platform
  • Should be able to provide feedback to EPA on what the next platform will be
  • 2016 was decided on through regional collaboration because it was a year that had ozone but was not anomalous for most of the country; preliminary and consensus document explains why the year was chosen
  • Can we find a hybrid approach that aligns the collaborative approach with the triennial NEI for 2020?

June 12, 2019

WG roundtable: update on the WG v1 activities, including check in on timing

  • Nonpoint : Finalize base emissions by the end of June, and work on projections in July; received growth/control packets from MARAMA

  • NonIPM Point : comments from WG members; majority for the projection year, trying to finalize 2016 base by beginning of July, waiting on aircraft emissions from EPA; projections will begin after base year is final, targeting end of July, will include state-submit growth/control packets and consent decrees, will also include MARAMA growth/control packets

  • Biogenics : integrated Environment Climate Change Canada BELD4 data, expect to have these completed for V1; running both MEGAN and BEIS3 for summer 2013 for comparison to emissions flux observations; for other modeling domains (other than CONUS 36/12) get in touch with Jeff V.

  • EGU : incorporating new ERTAC EGU into modeling platform, fairly large changes for the SE US, smaller changes elsewhere; WESTAR/WRAP will provide annual data for V1 for 2016 and 2028, suggestion to interface with EGU workgroup to work out how best to provide these data within the platform (what data are needed, formats, scripts, documentation) to make this a model-ready component of the platform, Tom will have a call with the EGU workgroup next week (Alison to organize, send a list of who wants to be on the call) to work through the details, these data will be available on the timeframe of the other V1 emissions; EPA working on updated reference case for IPM, data will be posted in late June that incorporates new announced closures and SO2/PM emissions;

  • Fires: integrated new database; different direction on submitted data for NC and KS, now have more databases going into SMARTFIRE2 than used in the NEI, cleaned up some duplicates and redundancy in beta for V1; running BlueSky now for standard and sensitivity runs for fuel assignments and will be sending out for review; Rx burns increased by 0.5M acres in V1 vs beta; wildfires decreased by 100k acres from cleaning of the database; will include GA day specific inventory; targeting early July for inventories

  • Canada/Mexico: fixed spatial remapping issue with fires; no new emissions from Mexico will be available

  • Marine: C1C2 data are available now; hourly C3 emissions available for 36 and 12km domains, EPA will work with other domains to grid hourly 2017 data; OTAQ working through how to distributing processing codes; working on the file format for getting these data into SMOKE

  • Oil&Gas: base year changes for IL and PA; WRAP recently completed an oil and gas survey, working on turning this around into base and future year projection inventories, WG is trying to figure out how to integrate these data into the platform, need to receive by mid-July; base year is done, working on projections (based on AEO2019 and state data); beta used and average of 2014/16 activity for future year exploration, V1 is using 2011-2017 exploration data to inform a national default for the projections

  • Nonroad: integrated comments from beta (e.g., LADCO ag equipment profiles), plan to finish up base year by end of June, work on projection in July;

  • Onroad: working through decisions on how best to use 2016 activity data, still to do is to wade through the other inputs

  • Rail: a few changes to documentation but the data are mostly ready; some changes to MI yards and then will finalize 2016, 2017, 2023, and 2028; outstanding issue with integrating yard data for the NW railroads (found through discussion with WA), couldn't get a volunteer to fix this issue, will use what's already in the inventory; expecting to send data by late June, no changes to Class 2 and 3; only yards and documentation are outstanding

Review comments received on beta, and discuss plans for integration into v1

  • Forum Link
  • How to document beta changes/updates
    • Add narrative description in the v1 spec sheet of the changes from beta to V1
    • Create a wiki for beta with a list of the comments received by sector; WG co-leads to provide concise list of comments/updates to the beta platform

National report out call on June 26 @ noon Eastern

  • Zac to send out template by Friday 6/14; WG co-leads to return slides for the call by Monday 6/24
  • Next call Thursday Sept 26 @ noon Eastern

  1. WG roundtable: update on the WG v1 activities, including check in on timing
  2. Modeling WG update on analysis of beta emissions
  3. Model Evaluation Collaborative report
  4. 2016-based projection analysis products: are there any plot updates?


Alison, Zac, Eric, Winston, Caroline, Sarah, Tammy, Mark, Mary, John, Julie, Jeff, Doug, Tom R, Rodger

Minutes/Notes WG roundtable: update on the WG v1 activities, including check in on timing

  • Onroad : integrating VMT, population, and age distribution updates, working on getting all three years done by June, considering using AEO 2019 based factors; will run 2016, 2020, 2023, and 2028; hoping to have this ready by early July
    • Will this new run include the new version of MOVES with off-cycle improvements? No, not ready for V1
    • Could there be a follow-up run to integrate HDDV MOVES updates? The timing is unknown

  • Nonroad: data received from states for this effort and 2017NEI, under review and will be included in V1, EPA and NC came up with state to county, national to county equipment allocations for MOVES; hope to run model in June, results should be ready by end of June

  • CMV: EPA building 2016 and 2017 inventories, will give Collaborative an opportunity to comment before they're finalized; C3 inventory is ahead of the C1C2 inventory, should be ready in June; C1C2 will be ready later, maybe July; working on getting gridded hourly emissions at 36 and 12km domains; will need to be gridded to other domains by EPA, can't be done by modelers; have projection data by region, haven't figured out the most efficient way to project these data

  • Rail: growth is pretty flat for rail, for controls there are updated emissions rates that are less aggressive than 2008 EPA guidance; future year rail inventories will be higher for new projections; some comments from WA comments into V1; trying to get the draft data out by next week, finalize by the end of the May; rail yards and commuter rail are included in these inventories; commuter rail included in the inventory as C1C2, collecting data from states on commuter rail equipment;

  • EGU: finished ERTAC EGU run and working on sorting out some discrepancies; don't expect a lot of change between beta and V1, but know of a lot of changes that need to be corrected, expect an update to this sector beyond V1; IPM will also not have a lot of changes from beta to V1 for the base year; found issues with IPM projections SO2 rates that weren't inline with the base year, working on a version to address this issue in time for V1;

  • Non-EGU point: Most of the work being done on the projections; airport data needs to be updated for the base case, waiting on updates from the new FAA model, expecting end of May for these data; states have been providing comments on beta, adding consent decrees and other state data into the projection packets for use in the next processing period in June; EPA posted for non-point and non-EGU point summaries of the projection packets, and the actual packets; need to figure out how best to fold in additional projection information from the states and regions; MARAMA will have projection packets that are different from the rest of the country

  • Oil and gas: Base year nonpoint update to the PA inventory; receiving feedback from some states (e.g., IL nonpoint O&G) that may lead to updates in V1; not anticipating any changes to base point sources; most of the activity happening on projections - WRAP will submit multiple projection scenarios for their states, how it will be delivered is TBD; what will the default projection method be for V1, leaning toward AEO reference case; didn't project outside of production, will try to also project transmission; the workgroup has been looking at the data at more granular level than state; states encouraged to submit data; still in feedback mode through the end of May, expecting information from IL, PA, and OK and expect to have an inventory by the end of June

  • Nonpoint: most of the work being done on the projections; working on updating base year animal counts, comparing draft NEI2017 submissions and 2016; will likely update the 2016 counts to the 2017 numbers, will have impacts to both base and projections; states are active reviewing control packets, which will be integrated into the V1 inventory; looking at the end of June

  • Biogenic: not a lot of changes are planned; nobody has given a full evaluation comparing MEGAN and BEIS; environment canada provided much better data that is BELD4-like; EPA is trying to integrate these data into V1; AZ has provided land use changes, and WG trying to figure out if the data can be used for V1; looking at running MEGAN and BEIS for 2013 to take advantage of summertime isoprene flux data from an aircraft field campaign in the SE

  • Fires: New Rx and FWS database going into Smartfire2; NJ submitted their own fire activity; Smartfire2 integrates satellite detects and different fire databases to get acres burned; running the new data through the models to understand the emissions changes; cleaning up some bad/redundant fire data in the beta inventory, found by looking at daily top 25 fires; Rx fires will likely go up a bit as new databases are integrated, wildfires may decrease as data are cleaned up; looking at a new PM2.5 speciation profile; not getting a lot of feedback outside of the air quality modelers; trying to wrap everything up by the middle of July; GA will provide day-specific ag fires for V1, improvement over monthly inventories used for beta; ag fire emissions factors are being reviewed, and could be updated based on work from 2017; FINN used for Mexico and Environment Canada for Canada

  • Canada/Mexico: Canada ag NH3 and PM gridding correction will be made to V1; looking at dust emissions over estimates in Canada, will leave out wind erosion sources and setting construction back to 2010 levels; have data to project to 2023 and 2028, but not expecting additional data from Canada; formal inventory request sent to Mexico, but have not yet heard back;

Modeling WG update on analysis of beta emissions

Attendees Zac, Alison, Shawn, Tammy, Jeff, Mark, Zac, Susan, Julie, Serpil, Doug, John H., Tom Moore, Tom Richardson, Mary, Rodger


  • Beta downloads so far from IWDW and transfer of met and IC/BCs
    • 20 or so requests from several states, universities, MJOs, NOAA, and consultants
    • CIRA: distribution is going smoothly, most requests have been for data volumes that can be done electronically (http or ftp); not too many requests for everything
    • SFTP may require a special client for Windows users; benefits to SFTP clients is that some can restart broken connections
    • CIRA has a lot of bandwidth and can accommodate several large requests
    • Drives on the way from CIRA to EPA for transfer of met, IC/BCs, and AQM outputs

  • Finalizing beta projections and documentation for pt_oilgas, np_oilgas, ptnonipm, nonpt, ptegu (IPM), and Canada
    • Several updates since last call, all sectors except Canada generated now
    • EGU modeling considerations being worked through - new types of sources and temporal allocation approach; expecting a slightly different PM representation from CAMD that takes more information from the base year (PM will change); doesn't apply to ERTAC
    • Received information from Canada for projections, future years for some sectors, spreadsheet for other sectors to project from 2015; will not need to fall back to previous inventory years; will provide these when they're done
    • Documentation - drafts of spec sheets that included the future years can be accessed by the WG, will need to finish the documentation for these last few sectors; MARAMA is working on ERTAC EGU documentation

  • Workgroup updates on their plans for improving the beta projections - including update from Tom Moore
    • Biogenics - no updates, looking to get Environment Canada BELD updates into v1
    • Fires - a lot new information coming in from USFS and FLMs to add to SmartFire/Bluesky runs; lots of new data and cleaning up issues; probably not a huge difference to wildfires (consistent across national groups); rx burning will change
    • Onroad - recieved specific inputs from states (representative counties, activity), big impact will CRC115 on age distribution and vehicle populations
    • Nonroad - work done on allocation factors from national -> counties for ag an construction factors for base and future years
    • Nonpoint - see report out slides
    • Oil & Gas - base year changes will be in PA nonpoint, looking closely at beta base year, future year projections will move to AEO2019; move to higher resolution regions for classifying data; potential reporting change to reclassify how sources are grouped: i.e., upstream/midstream vs. point/area;
      • Tom: over 40 responses and > 250 profiles received in oil and gas survey; proposing new data for v1 and projections that integrate these new data for some western states; need to coordinate on gathering these data, will facilitate consistency with Western regional haze work; surveys at the basin level; states impacted: ND, SD, MT, WY, CO, UT, NM, and Tribal areas; can provide updated emissions
      • EPA trying to get v1 platform out by July/August; Tom thinks that we can get the data by then
    • Point EGU
      • IPM updating 2023 and new PM, no new retirements
      • ERTAC to provide minor update (v16.1) for v1 - changes in Southeast; ERTAC is planning another round of comments for summer to fall; updates to AEO growth factors, oil growth factors in the NE would come later in the fall; ERTAC files for v16.0 are posted on the MARAMA website;
      • Tom: 13 WRAP states and EGU operators have worked together to create current baseline emissions inventory and 2028 projection for the coal/gas units that are still in operation; will provide emissions for 2016 and 2028 units for the Western U.S., will be used in haze planning; 11 states (other than Dakotas) are on the same grid; will need to get both inputs and outputs; timing: data files are available, June timeframe; for the base period using a nameplate capacity factor or MW/hours and vetted with states/operators; is the model avoiding overcapacity in the projections, check documentation
    • Non-EGU Point
      • Changing aircraft to EDMS inventories and projections; some states providing growth/control information, integration with MARAMA spreadsheet
    • Rail - OTAQ isn't helping with future year technology forecasts, straight lining the current data; 2028 rail may double compared to 2011 platform projections because new projections don't show the technology turnover originally forecast by OTAQ
    • CMV - EPA OTAQ and marine committee are not working together; 2017 NEI was on it's own course - developing an AIS based inventory; don't have a method yet to backcast to 2016; some projections for beta - factors for v1 may be similar
    • Mexico - EPA working on getting 2016 emissions for v1; Mexico looking for a more formal request

  • MARAMA projection factors, and applicability - to which sectors are these being applied?
    • EPA coordinating on the projection factors and where it could be incorporated into v1; some specific growth information, and control factors
    • Sectors: nonpoint, area fugitive dust, construction, ag
    • AEO - what workgroups are using AEO2019? oil & gas, maybe onroad, not sure about ptnonipm and nonpt

  • Single vs scenario projections - we’re targeting single year (i.e., 2023) projection inventories; are there any sectors considering future year scenarios, like 2023 low emissions and 2023 high emissions cases?
    • ERTAC in the past has done projection scenarios
    • Western state oil & gas: high/med/low emissions scenarios, could be discussed with the national workgroup
    • Think about building internally consistent platforms

  • EPA update on 2020 projections for the states with 2008 NAAQS obligations
    • EPA is not generating a full 2020 set of projected inventories
    • EPA can provide 2020 onroad emissions factors and nonroad emissions based off of v1 configuration

  • Timing for v1 inventory
    • Targeting for emissions inentories to be ready by June, packaged and available by July; may be ambitious and some sectors may miss that
    • Modeling WG members want modeling files for the beta projections - Alison to follow up on this

  • Model performance Evaluation Collaborative - contact Heather Simon of you want to be involved but haven't plugged in yet.

March 13, 2019


  1. Status of 2016 beta release
  2. Status of future year emissions inventories
  3. Modeling workgroup update
  4. Timing for v1 inventory: see
  5. Please review dates for your sectors
  6. Preparation for quarterly update planned for April 3

Attendees Zac, Alison, Caroline, Jeff, Mark, Eric, Chet, Sarah, Tammy, Shawn, Doug, John H, Michael, Julie, Susan and Debbie (MARAMA), Mary


  • Beta release
    • Update from EPA: (Chet Wayland) Thanks for efforts on the Collaborative, apology on the delays, no control over shutdown, were looking to get things done sooner;
      • Status and update on where EPA is with the beta platform: it's been educational for EPA, concerns that even though it's a collaborative effort, even though it's public, it has an EPA endorsement because they are part of the collaborative;
      • EPA wants to be clear that the beta is not for regulatory applications, wait for v1; for 2016 beta it's a better quality than the projections, no concerns about public release of 2016; have concerns about requests for the 2023 and 2028 beta from people outside of the states/MJOs; fine with sharing 2023 and 2028 with states, hesitant about putting beta out for public use, would like some control over uses by groups outside of the states; delay was really on the projections not the base year;
      • Proposal: can we release the 2023 and 2028 to the states, receive comments from states, and then put the public release with projections out for v1?
      • Need to be clear that beta shouldn't be used in formal regulatory applications; will also be talking about this on the federal-state and MJO call this Friday
    • (MARAMA) Agree with beta release; don't let v1 slip too far, timing is key
    • (LADCO) Once beta is released, how do we keep it from being distributed outside of the states? Don't really have control over this, just need to communicate that these are evaluation data for looking for problems and testing; discourage people from thinking this is a finished product;
    • (MARAMA) Can we share these data with modeling contractors? EPA doesn't want to limit how states are using these data, just need to communicate to the contractors that these data are for testing, states need to be able to conduct their business;
    • (EPA) Others outside of the Collaborative will likely get these data, just need to communicate the expected use; are people clear that we'll release the beta year projections to the Collaborative only? Industry is being told by EPA that the beta inventory is being used by states and EPA, will be available as version 1 later this summer; states/regions work with universities/contractors to not distribute these data
    • Need to craft a common response: beta an internal gov't deliverable, interim product and not available to share for public use
    • (TCEQ) Are we limiting input by not including other people; the requests are coming from contractors? It's a fair point, hope is that we'll get feedback on the public product; how will we integrate comments on v1 if we don't want a v2? Don't expect a lot of comments on beta, will we get something significant enough to integrate into a second version? Need to figure what happens to the Collaborative post v1, will shelve that discussion for later, but need to know that it will be coming
    • Will need to work out logistics of release the future year data when it's ready (how do we document and provide a limited release to states)
    • beta release will go out today if we all agree an EPA's proposal, and the release logistics
    • Documentation for 2016 is available; reviewed and more complete than first drafts; removed references to future year emissions, old documents are still available and the future year content will be added back in when the future year data are ready to release
    • 2016 emission data are at the IWDW and a data download form is available; form is up and running on the IWDW
    • CMAS Center tool can track comments on the platform; is there a deadline for comments? start with end of May for closing comment period; need to allow enough time for summer release of v1.
    • Met data and IC/BCs will be transferred to IWDW soon; disk drives on the way to EPA from the IWDW for transferring the data to the IWDW; extracted met files are available on EPA ftp site under beta platform area;
    • Release approach: send announcement to MJOs and circulate list for the national call out

  • Future year inventory status
    • Ptegu (IPM), ptnonipm, nonpt, pt_oilgas, np_oilgas in progress
    • Keep hoping Canada will provide future year inventories - otherwise need to project from 2015 based on old projections; Canadians have been delayed at providing future year data, no idea on when these data become available; fallback plan is to project 2015 using rates of change from previous Canadian inventories
    • Hoping for 2016 inventory from Mexico by version 1; discussions on expected future year changes

  • Modeling workgroup update
    • Worked on beta documentation; will be working on processing the data and sharing our experience

  • Timing for v1
    • Review Timing Worksheet ; some sectors coming together in April, most ready by June; workgroup co-chairs review and update dates;
    • There will be an effort to pull the platform together: at this point, looking like July for the platform release if all the sectors are done by June
    • ERTAC EGU - June probably won't pose a problem
    • For comments by end of May, how will that impact timing? timing estimates are based on what we currently know; there is an unknown because we don't know what and how many comments will be received; not all comments will be able to be assimilated due to timing and nature of the comments
    • When v1 is released, how do we consider comments from people outside of the Collaborative; need to think about how comments, post-v1 will be received; let's discuss on the next call, gets into issues of tracking comments, and commitment from the Collaborative moving forward
    • Will impact sectors differently, will likely get a lot of comments on point, how do we put these comments together; need to consider standard naming convention for versioning; try to get names in place to track inventory segments easily and consistently; how will the different inventory components get pieced together into platforms moving forward?

  • Preparation for Quarterly update April 3
    • Zac to send template; get back to Zac by Monday April 1
    • Summary of beta, release, and comments; describe beta projections abd release
    • introduction to v1
    • timing and discussion for v1; focus on what they're planning to do in v1
    • results of beta, show some pictures, plans for v1

  • How to release future year inventories? Google drive with limited access?
    • can use sftp at IWDW

  • Documentation
    • Documentation is being worked on by co-chairs
    • It would be helpful to have a roadmap/spreadsheet to track the status of documentation, plots needed, what's missing to complete the documentation, include locations of where things are
    • Need to add space to Google Drive (LADCO)
    • ERTAC EGU: need to add information/documentation; how should we document other work, that's been outside of the collaborative but relevant (e.g., point temporalization work at EPA); yes, this needs to get into the Google Drive and documentation for the collaborative
    • Mark will create an area for the ERTAC EGU data (in the beta data repo)

  • Future year inventories: ptnonipm, pt_oilgas and np_oilgas still need to be wrapped up
    • EGU inventories are available, but modeling techniques need to be worked out

  • beta Release pros and cons
    • Do we release base data now and wait on future year?
    • Yes, get the base platform released; will release future data when they become available
    • Downsides, questions about future year
    • Upsides: model performance evaluation, get outside groups working on these data, release data before/if EPA shuts down
    • Upsides outweigh the downsides
    • When can the documentation be ready? EPA scheduled to shutdown 2/15. Target 2/14 for documentation draft and create tracking spreadsheet for progress; what is the minimum level of documentation that's needed, don't want to have a sector hold up the release
  • Let the workgroups know that the documentation work is happening
  • Zac to send specification sheets from WRAP WestJump for all sectors
  • Point people to documentation folder for draft beta inventory docs
  • Look at daa repo organization; include an entry in tracking spreadsheet where documentation is located

  • Modeling Workgroup update
    • Some summaries and input files posted on Drive
    • Full package of emissions inputs is available via scienceftp
    • Maps and charts have been generated
    • Use density maps and plots on the LADCO image viewer for documentation; create customized plots with CIRA tool
    • How much lead time will CIRA get for releasing the data? Prepare the release with what they have now, will include the documentation as it becomes available
    • Target release before the end of February

  • Timing for v1
    • Timing will be delayed due to shutdown
    • Move from March/April to May/June? EPA will regroup and try to estimate how the shutdown has impacted this platform release
    • Talk on the next coordination call on the impacts to each sector

  • Next quarterly update scheduled for April 3, 2019

January 11, 2019

Agenda Discuss the status and ongoing work of the Collaborative during the government shutdown.

Attendees Zac, Mark, Susan, Tom, Eric, Debbie, Doug, John, Jim, Michael, Rebecca


  • Do we suspend the collaborative completely while the gov't is shutdown?
    • Concerns in MARAMA about an EPA grant that finishes Jan 31, 2019 for supporting growth and controls; working with sector workgroups to gather/improve projection information; delays in the collaborative will impact their ability to complete their grant work
    • States are proceeding with their statutory obligations as if nothing was happening: permit applications are being submitted, NEI2017 submittals are being sent in, etc.
  • Are there functions that this collaborative can continue without EPA?
    • documentation work can be done; inventory development will likely need to wait for EPA participation
    • several co-leads agreed that work should continue to the extent possible
    • there is a need to distinguish between the work on the beta and v1 platforms
  • What have the workgroups been up to, and are they working without the EPA
    • Rail and marine do not have EPA co-leads anyway, they have been proceeding with work on the documentation
    • Fires and O&G decided to move forward with the documentation work
    • Biogenic workgroup is working on MEGAN, need EPA participation for BEIS documentation
    • Nonroad will proceed
    • Onroad and nonpoint need EPA to proceed
  • Plan is to move forward with completing the beta platform documentation, in lieu of the EPA participation; we will wait to see what happens before making a call on how to proceed with v1
    • workgroup co-leads will continue work on the beta documentation, working toward the January 31 deadline
    • modeling workgroup will provide summary plots to include in the sector workgroup specification sheets
    • when draft versions of the documents are ready, send to Zac for review/editing; Zac will recruit members of the coordination committee (other than sector WG co-leads) to help with review
  • There is general agreement that we do not want to release the beta platform without documentation; the EPA shutdown will delay the release

  • Alison, Mark, Caroline, Serpil, Susan, Tom, Eric, Debbie, Jeff, Julie, Doug


Status of beta emissions

  • EPA is doing 2016 beta modeling, processing inventories now for CMAQ and CAMx modeling; using this process as a QA step, addressing issues as working to run through SMOKE
  • close to having all sectors processed, a few late changes (e.g., Canada dust, processing rail yards, and rail lines); will have processed emissions by next week;
  • Running SMOKE for the base year; don’t have plans to run for the future years now;
  • Updates for future years will come in through the holidays (e.g., rail, O&G, non point, IPM EGU), then build the future year platforms.

Upload of beta summaries and inputs to Drive

  • Working on summaries requested by modeling workgroup to compare 2011, 2014, and 2016 cases (state-SCC, counties, state totals)
  • Including profile reports (temporal, spatial, chemical);
  • RWC and non-road reports copied to G-Drive;
  • EPA will provide EMF platform scripts in early January;
  • EPA will look into exporting cases from EPA EMF system and point to scripts;
  • Zac to schedule modeling workgroup for early January;
  • EMF Case settings file needed for non-SMOKE shops; add to data repo;
  • GE_DAT data are in the Shared folder on the G-Drive data repo
  • Not done at this point: rail, pt_oilgas, np_oilgas, ptnonipm, ptegu, ERTAC is coming; need to develop a version of small EGUs to work with ERTAC

Timing for Documentation

  • Getting requests from people within Collaborative and from outside for beta
  • January 18 for draft spec sheets;
  • Zac could edit / review draft, but WG co-leads need to pull content together
    • See WestJumpAQMS for example spec sheets by sector; scroll down to Emissions Materials to view spec sheets
  • Modeling WG to work on analysis;
  • Target end of January for documentation

Timing for v1

Where will there be big changes from beta to V1?

  • Rail: some changes to the base, hopefully newer technology
  • Marine: different in both the base and future (AIS-based for 2017 draft in January)
  • Nonpoint: finishing up controls for beta; for V1 will get contractor support for open burning adjustments, goal is January/February impacting base and future years; other future year adjustments
  • Onroad: age distributions in January, need to allow time for representative county updates (1 month), settle down to have data ready in March; need a month or so to integrate new data + a month for MOVES run
  • Nonroad: aiming to get modeling in mid-February; mid-January for state-supplied data; probably not big changes between beta and V1
  • EGU: no changes to base year (unless review issue with beta); just looking at IPM now may not have changes; ERTAC EGU will change if there are new shutdowns or QA/QC issues with current data, no plans on new version; Western interconnect update project will have 2028 data available in March, will need work to introduce into Collaborative
  • nonEGU: changes to base with aircraft/airport; 2017 run is going new, will be used for 2016 base; this sector would change for the projections off of this base, could be done by spring
  • Oil & Gas: simplified projections for beta; looking to improve in V1, base year wouldn’t change much but projections will likely; planning on getting the projections
  • Biogenics: no changes planned
  • Fires: no changes? may have data that came in late to update in V1

Targeting April 2019 release

Preparation for large group call

  • Zac to send template tomorrow; get back by Tuesday;
  • Wed April 3 noon next call

Follow up on 2020

  • Last month had suggested a discussion with OTAQ on this
  • EPA looking to run MOVES (onroad) and NONROAD for 2020 by April 2019
    • EPA needs to get management approval for this work

Transfer of data to IWDW / release to the community

  • See Draft IWDW Support for Inventory Collaborative
  • IWDW to host the 2016 emissions files; outline for organization platform components; worked on building out the file system structure and adding data as they become available; will also host met and BCs, in addition to emissions, and air quality model output as it becomes available
    • software, met, emissions, bcs, and eventually model outputs
    • Decided to host all versions of the platform
    • will send a drive to transfer the met and processed emissions
    • will host SMOKE output files
    • provide the met data needed to create the processed emissions
  • EPA will make BC data available
    • MJOs respond to Norm about needs for ICBC data: what is the parent domain;
    • EPA can extract data as needed if we can come up with a common modeling domain;
    • EPA moving to Hemispheric CMAQ; EPA will provide presentation on the comparison between GC and HemiCMAQ; 36 US domain for downscaling to 12US2;
    • Will there be documentation on the BCs? There will be a manuscript;
    • MJOs need to coordinate on parent domain (horizontal and vertical structure);
    • IWDW is a warehouse, not planning on doing file manipulation; how much prior manipulation of the files will be done, need to tell IWDW what was done with the files before they are sent;

  4. Beta progress issues by sector leads, as needed
  5. Needs for 2020 mobile source data
  6. Modeling workgroup update
  7. Issues / agenda items from coordination WG members


  • Alison, Mark, Caroline, Serpil, Susan, Tom, Eric, Debbie, Jeff, Julie, Doug


Documentation for the beta inventories

  • Timeline: before the end of the year for documentation - lower priority than finishing data
    • EOY seems doable for biogenics, could be tough for oil and gas, other TBD
  • What is level of documentation desired? See the specification sheet example
  • Centralize the documents into a G Drive documentation folder while we are working on it - Alison added a documentation under the Data Repository for beta to put sharable versions of documentation
  • End up with a library of spec sheets and put together a leading chapter

Data repositories for beta files

  • Data repository: inputs to SMOKE and documentation can go on Drive area that Zac set up (outputs are too big)
  • IWDW can host outputs from SMOKE (Globus FTP is high volume / fast FTP)
  • Disks can be loaded [by Roger Aimes] if drives are provided to the IWDW
  • Mark would like to be able to receive one tar ball with EFs and SMOKE and inputs as had been provided for the previous platform
  • Mark would like to be able to get Drives straight from EPA when possible [about 2 TB], but if IWDW can provide in a timely fashion that is OK too
  • EPA could FTP some sector outputs as they are ready for putting into a structure that will be filled out over time
  • MJOs will pull together the folks that want to send drives
  • Action item: some volunteers to meet with Roger about how to draft a guidance document [Mark can help, others will review]
  • Group would plan to check it over on December call [include Jeff and Julie on this]
  • Could try out biogenic data as test case - FTP is simple for this

Inventory collaborative platform use cases and tracking

  • looked over the draft that Zac put together
  • Action: need to add inventory documentation link
  • No other comments just yet

Beta progress issues by sector leads, as needed

  • EGUs - assignment of peaking profiles to units without CEMS is being finalized; ERTAC cases are coming along [folding in some last minute closures]; IPM cases are being worked on / reviewed
    • Southeast regional haze analysis - looked at double counting / missing units - NC used an approach to look at things with GIS for units close to each other
    • will talk about this on next EGU WG call (would be a v1 issue)
  • Oil and gas data for last couple of states and also for projections being worked out
  • Rail yards and line haul still coming this week and can then be projected

Needs for 2020 mobile source data

  • Tom has asked western states - Colorado response will be sent
  • Julie will respond to the questions Alison sent
    • question about use of Advanced EV in the Northeast - may require a different approach using inventory MOVES
    • strategies will be important to look at for their purposes
  • mobile will be an important player in 2020
  • Action: schedule a discussion about some of the issues in December
    • OTAQ will need to participate in this discussion [e.g., to run MOVES on cloud]
  • need to get cloud tools out to MJOs/states

Modeling workgroup update (Eric)

  • Had first group meeting last month; Jeff and Mark were also there
  • Group agreed that initially they won't be recreating a new platform - work on analysis, improvement, documentation,
  • WIll strive to develop some additional reports for emissions modeling
  • Could look at ancillary data for improvements / updates
  • Prepare instructions to swap out a different domain or use difft inventories
  • Next meeting will be after Thanksgiving

October 10, 2018

Next Call: November 14, 2018 @ 2:00 Eastern


  1. Documentation for the beta inventories
  2. Data repositories for beta files
  3. Inventory collaborative platform use cases and tracking
  4. Beta progress issues by sector leads, as needed
  5. Modeling workgroup update
  6. Issues / agenda items from coordination WG members


  • Jeff, Susan, Rebecca, Julie, Michael, Mary, Mark, Caroline, Sarah, Zac, Serpil, Eric, Tom, Alison


Documentation for the beta inventories

  • Timeline: before the end of the year for documentation, but will come after the data
  • As important as the data
  • What is level of documentation desired? See the specification sheet example
  • End up with a library of spec sheets and put together a leading chapter
  • Centralize the documents into a G Drive documentation folder while we are working on it
  • When finished, convert to PDF and package with the data
  • Action Item: Zac to create a Google Drive for documentation; send link to workgroup co-leads
  • Tom: Need to create a layperson description of the inventory collaborative: FAQs and slides; need to track this collaborative component of an air quality modeling platform
    • Note we'll have a high-level presentation on collaborative for CMAS
  • Julie: suggest we hold inventory documentation static and then have another piece of documentation for the modeling
  • Modeling platform workgroup will have documentation coming later; need to include FAQs and pointers to the data; document the findings in the modeling workgroup, will be looking for feedback from outside users in a form similar to what the modeling WG provides
  • Should we have an online forum for discussion?
    • Alison: CMAS has been working on setting up user forums
    • Something like that would be helpful here, especially if it's searchable
  • Describe how to do the file transfers; need organization
  • Should there be a list of files and what is in them? [Appendix]
    • Perhaps name those tables, and have a tree that shows the options by sector

Data repositories for beta files

  • Add a table to the spec sheets that describes what’s included in each sector
  • Action Item: Zac to create a central Google Drive for beta inventories with subfolders by sector
  • Include dates in all file names for versioning
  • Stage data first on the G Drive and then figure out where to put these files later
  • Do we want beta to be released to public?
    • Zac thinks yes, but wait until the documentation is ready to make publicly available

Inventory collaborative platform use cases and tracking

  • How to track the data and assimilate and fix problems/issues found during use of the data
  • Who is using the files? Get descriptions of their use case, timing, and contact, issues they’ve found;
  • Tracking info could be added to the wiki in a new page; prototype with EPA use case
  • Action Item: Zac to create collaborative uses wiki, with initial entry for EPA 2016 modeling
  • Use of the alpha: Tom surprised by EPA regional haze road map because it says EPA will produce nat’l regional haze modeling results at the same time as states doing their own analysis; need to be sensitivity to the fact that multiple results could be problematic; there are potential problems with a 50 state RH planning platform
  • Need to be sensitive about how we describe the use cases
  • Describe where the modeling platform workgroup fits in with the use cases
  • Challenge with different projections across the country is that the future modeling will likely produce different amounts of progress; if EPA presents a national case, it will be the individual states that have to explain what EPA modeling is saying, because the numbers will be different from the regional estimates

Beta progress issues by sector leads, as needed

  • Marine doesn’t have an EPA co-chair
  • EPA is building a 2017 inventory independent of the collaborative, no input from states in this process; contracting to build category 1 & 2, cat 3 is being done in-house by OTAQ
  • Fighting in the collaborative marine committee to get information from EPA, looking to get data that costs money to obtain; EPA is buying these data but not sharing with the collaborative;
  • EPA has obligation for 2017 NEI and it’s independent of this collaborative;
  • There has been passing back and forth between OTAQ and the collaborative; there hasn’t been radio silence from EPA
  • Collaborative getting code from OTAQ for C3, but won’t get the data to drive the code; problems are activity data through AIS, but need to be matched to ship parameters, and these parameters are proprietary data purchases; need to deidentify the data somehow
  • What happens if you need proprietary (commercial data)? Oil and gas purchased the commercial data for other reporting aspects, feeds into the Oil & gas tool. The O&G tool de-identifies the proprietary information
  • Need to engage EPA to work on the marine workgroup; does the marine effort involve regions for the 2017 emissions effort; can we get an EPA regional office lead?
  • Can Sarah explore if there is a middle ground to provide something of value to this workgroup
  • Similar issues with O&G database, contractors were hired by EPA despite recommendations otherwise; looking to be more closely engaged with EPA; long effort to collaborate between EPA and regions/states; benefits for both sides, not just EPA giving

Modeling workgroup update Issues / agenda items from coordination WG members

Transition to v1

  • When will this effort end? Some sectors have small changes beta to v1, others will have large changes; others will have changes to projections
  • Beta documentation will be starting point for v1 documentation
  • Some data will transfer over from beta easily; other sectors are harder

September 12, 2018

Next Call: October 10, 2018 @ 2:00 Eastern


Alison, Sarah, Jeff, Mark J, Tammy, Mary, Caroline, Husain, Tom, Zac, Julie, Debbie, Jim, Rebecca, Gail, Dave, Susan and Debbie (MARAMA)


  1. Review action items from previous meeting
  2. Beta progress highlights by sector leads
  3. Modeling workgroup update - co-leads and group initiation
  4. October 31 target for completed inventories
  5. Quarterly Report Out Call: September 20
  6. Beta documentation
  7. Projection planning and discussion: update on MARAMA's projection tool and collaboration on this
  8. Issues / agenda items from coordination WG members [All]
  9. Date for next quarterly call


Review action items from previous meeting

  • No action items from last meeting

Beta progress highlights by sector leads

  • Onroad: activity data for 2016 finalized and SMOKE-MOVES has been run. Will provide data to workgroup next week. Draft national projection factors by vehicle and fuel based on AEO2018 have been developed and will be presented to the workgroup next week. Once activity projection method is finalized, SMOKE-MOVES runs can proceed. On track to finish before 10/31. ERG is running MOVES on the AWS cloud. No MOVES CDB updates made for beta, but v1 will include CRC A-115 updates.

  • Nonroad: have performed a test run of MOVES2014b for 4 counties and 3 years (2016, 2023, 2028). Reviewing results now and getting ready for national runs. Beta version will be default run of new model and is on track for 10/31. Following review of beta data, v1 will include state updates and improved allocations to counties.

  • CMV: Beta will be a projection of 2014NEIv2 to '16, '23, '28 and that could be available by 10/31. Will discuss with workgroup next week. For v1.0, WG found a public source of AIS data that should be usable as input to the new method. EPA OTAQ released calculation method for ships to LADCO and CA.

  • Rail: the WG will make the 10/31 date and has incorporated new data from rail companies and passenger rail as well. Projections should be available; flat growth rates. Challenged by assumptions about future engine technologies.

  • EGU: cross reference for the base and future year splitting of EGUs from non-EGUs is nearly done and will support completion of emissions by 10/31. WG is working on temporal allocation approaches for sources without CEMS. ERTAC projection to 2023 should be available around 10/31 with 2028 to follow. EPA working on projections to 2023/2028 using new version of IPM but unsure of completion date. The IPM data includes information on plant closures/fuel switches/changes through at least 2016

  • Non-EGU point: Base year will be split from EGUs and available by 10/31. Working on future year projections: consent decrees, control and projection packets. Consent decree information sent to states for comment, seeking comments on decrees and emissions caps; waiting for aircraft modeling results, will include projections for these sources in V1.

  • Oil and gas: EPA to run oil and gas tool for 2016. Projections subgroup working on growth part of projections. WV, TX, and OH to provide data for beta - others may add for v1.0. Should have base year by 10/31 but projections may be a little delayed. Some states may want to pull data forward from 2014.

  • Nonpoint: WG has determined which subsectors will be pulled forward vs projected and is reviewing data for combustion sources. New population data from ICLUS will be available to use to project sectors that use population as a surrogate.

  • Biogenic: MEGAN and BEIS versions are available. May redo the BEIS runs with updated landuse data. Would like to compare to field data, where possible (looking at SENEX data for summer 2013). AQM runs are desired for this sector.

  • Fires: Received data from 8 states and new national data sets are available. Waiting on a dataset from USFS. Beta should be available by 10/31 and is approaching NEI quality. Split into wild, prescribed, and ag like NEI - pile burns are in nonpoint. Don't have good coverage for prescribed fire smoke management burns. No plans for future year alternatives for beta, but maybe for v1.0.

  • HAPs: Are we including these? They will be included to a point (where it is straightfoward), but not with the same level of QA as CAPs. Zac thinks having having HAPs in v1 would be helpful as we don't know all uses of the modeling for now.

Modeling workgroup update

  • Hussein from MD will be a co-lead.
  • EPA is working on identifying a co-lead.
  • In the meantime, Zac will help get the WG up and running and identify members.
  • The WG will process inventories through SMOKE and will be the first testers of the data and will help review the data.
  • The result of the WG will be an emissions modeling platform with AQM-ready inputs.
  • EPA will create a version of the platform with the configuration they plan to use
  • This WG will allow for other configurations to be developed and facilitate other modeling centers will be able to do their own modeling
  • Mark points out that the marine and rail WGs will need to interface with this WG, as there will be a couple options for configuring these sectors
  • Tom requested that sector leads be included in the kickoff call

October 31 target for completed inventories

  • Base year inventories should be available for all sectors
  • Future year inventories may lag for a couple sectors
  • Working towards a freeze point for the data products
  • The products will be SMOKE input files (most are FF10), not AQM-ready files
  • Would be helpful to create a record/track of where the alpha, beta, v1 platforms are being used
  • ActionAction: Zac to create a spreadsheet for tracking use of the platforms)
  • If FF10 files are ready before Oct 31, please share via Google Drive, with the group

September 20 Quarterly report out call

  • We will keep the date of the call as-is, but if additional outreach needed for hurricane-affected states, that will be arranged
  • The reminder will be sent a week before and will include the link to Wiki page
  • Slide deck template is available - try to include some graphics for interest
  • Get all slides to Zac by noon September 19

Beta documentation and data release

  • Tom asked about compiling a list of applications for the beta by EPA and others - perhaps to discuss on next quarterly call
  • We want to try to standardize the documentation with the specification sheet
  • Want to document what was produced and where can people find it?
  • Show how data came together, where they came from, analyses, summaries
  • Try to leverage human resources on WG to develop docn
  • Action: Revisit the previously provided template prior to the next call - there was one created for ag NH3 emissions months ago

Projection planning and discussion: update on MARAMA's projection tool and Collaboration

  • MARAMA hosted webinars to educate others on their tool and also had conversations with leadership group on this
  • Used EPA approach in some cases and new ideas in others
  • It won't be possible to use the tool for beta - target is v1
  • Will be able to apply methods used to develop 2023 and 2028 for beta and extend to other years
  • EPA is focused on developing default approaches and can help extend to other years once 2023 and 2028 for beta are done
  • If regions outside of MARAMA want to outreach to their states on various options, they would need to take the lead
  • Zac will get back to Julie about his region and other regional leaders are responsible for theirs

Other Issues

  • None raised

Date for next quarterly call: Wednesday December 19 at noon

Review action items from previous meeting

  • Zac: create an evaluation spreadsheet template for WG co-leads to use for comparing 2016beta with 2016alpha and 2014v2 (and 2011v6?)
    • Status: See evaluation product strawman
    • Zac suggests some state totals, county totals, maps, bar charts, pie charts, thematic county maps of differences in annual state totals for each criteria pollutant in inventories If groups can create FF10s, then perhaps EPA can help automate generation of comparisons and maps
  • Jeff and Doug: consider whether / when air quality modeling for biogenics is feasible
    • Status: ready to go and provide files, don't have a group ready to modeling
    • need met and boundary conditions; go with alpha or wait for beta
  • Julie: arrange for overview of projection spreadsheets
    • Status: put a google doc with draft approach on Google Drive and working on a plan for doing projections off of 2016, including a timeline;
    • Julie put some spreadsheets on Google docs - working on a workplan [have funding now]; has some ideas for who might do what; asked MARAMA states for some things as growth indicators [VMT, population, employment]; will not be possible to finish for beta, but more version 1;
    • who would coordinate subregional data to work on collecting data? (MARAMA can't for all states)
    • LADCO states - they may be able to do this if MARAMA can provide list of info and where typically get data
    • provided webinar to nonpoint folks: schedule webinar for growth - publicize a date - feedback for nonpoint?
    • Julie will send slide deck to this group
    • Tom: won't be factors for many sectors beyond what MARAMA had - problem will persist beyond v1? what about communicating with states in southeast and West? doing something and showing it is different than giving folks a chance for input; e.g. oil and gas projections?
    • Julie points out they provide options / what ifs; different states do different things [e.g., past 2030]; people are willing to use something are comfortable with; what if people are not engaged? [this will happen]
    • Mark: let workgroups talk through growth options and select; agreed - delegate default growth to workgroups
    • include link to Julie's doc in the meeting notes

Beta progress highlights by sector leads

  • Onroad: close to having 2016 activity data with contributions from states, will have some maps and comparisons for the MJO call next week; hoteling comparison
  • EGU: progress on cross-walk between NEI and ERTAC; hopes to finalize this month
  • Biogenics: None
  • Fires: states submitted data, being implement for beta, cuttoff 8/17; implementing more federal fire information databases, bug fixes, fuel bed update from 2007 to 2014
  • Marine: EPA progressing with link-level AIS marine inventory tool, basis for the next marine inventory (C1, C2, C3); getting AIS data from the Coast Guard, still targeting v1
  • Nonpoint: Working with Judy Rand on combustion sources with AEO2014 for projections; working with EPA group on population projections for subsectors that use population as activity; working on ag as well; asked a couple of other states to fill in, nobody felt they could take on the work; Judy Rand (NJ) has stepped up and taken on a lot of this work
  • Nonroad: Beta run is ready to go, need a model; OTAQ will release 2014 NONROAD this month; working with geographic allocations
  • Oil & Gas: 2016 run of the oil and gas tool by the end of August, include in the beta version; may have new gridding surrogates and temporal profiles; starting work on projections through a subgroup, will likely be basic for the beta version
  • Non-EGU Point: working on controls that are still applicable in the future, looking at consent decrees and admin orders
  • Rail: new datasets and including commuter rail in the national inventory, in particular for the big urban areas; expect 2016 and 2017 in time for beta

Is October 31 reasonable date for beta cutoff? What if most sectors are available but a couple are not?

  • We know that there are needs for 2016 at EPA and elsewhere, late fall
  • Uncertainty in the projections, base year is coming along well
  • Whatever is ready at that point will go into SMOKE modeling; we will likely have a beta for 2016, and some sectors will have a future year, but what do we do for sectors where we don't have anything? Is there a default or is better to not run future years if we don't have a reasonable future year for every sector? There will be no projections off of alpha
  • Will likely need to talk to workgroups to figure out what the national default should be for sectors with no growth information
  • Do any groups not feel like they won't have 2016 beta by Oct 31
    • Marine
    • Oil & Gas
  • Selecting a date should be based on a model performance evaluation criteria
    • Projections are important, but need to do MPE on the base year first
    • Need to make sure that the documentation goes out with the projections
  • Example in a non-NEI year it's hard to get prescribed burning information from the states; won't be able to pull this together in the next couple of months; beta on the fire side will be weak; similar issues with oil and gas
  • Need to work hard on documentation by October 31 to include with the inventory/modeling platform

Projection planning and discussion: update on MARAMA's projection tool and collaboration on this

  • Worked with emissions inventory leads for information on growth indicators (e.g. VMT, population, employment)
  • Example outline is provided on GDrive:
  • If we're going to use anything other than national numbers for growth, this data collection effort needs to start right away
  • Currently being divided by sector, but the growth factors cut across sectors, it's not feasible for a single group to collect everything across the country
  • MARAMA working with the NE, should this be done by MJO for collecting projection data
  • MARAMA will send an example data call that they sent to their states, slides with information that they're collecting, workflow (collect, summarize, and then send questions to states on the quality of the data/approach)
  • Alison/Zac to organize a projection call for all of the workgroups to sit in on; get feedback from nonroad group on what else needs to be covered, get slide deck from Julie
  • How to work with sectors where is there is no factor for growth; how to work with states that aren't involved in the process? Can we hold things constant into the future?
    • There will likely be a national default for states that don't provide data
    • Create a decision point, here's the default provide additional information if you don't agree with this approach
    • MARAMA is putting out a strawman approach, will be looking for comments on how to improve;
    • What do you do in situations where nobody is engaged? Flatline or national default, needs to be the choice of the work group on the best default
  • Workgroup should be in the role for selecting default for areas where this is limited engagement

    • Status: done
  • Jeff and Doug: investigate what 2016 modeling data are available to use for evaluating biogenic emissions
    • Status: what elements of platform are available at this point - e.g., met, IC/BCs? Consider moving this thread to modeling WG.
  • Zac: Create an evaluation spreadsheet template for WG co-leads to use for comparing 2016beta with 2016alpha and 2014v2 (and 2011v6?)
    • Status: not complete, will work on it this month

Preparing for Beta

  • Will glider kits rule be included?
    • 2017 production cap in place, vacated to end of 2019
    • OTAQ is looking at how to include this in MOVES
    • Is this an issue that the onroad group should look at? Yes, can we just convert 4% of new sales to use 55x of emissions from new trucks, or convert new to old
    • if this holds, we could consider adjusting HD truck age distribution

  • What is beta? Need to agree, within this group, what beta is
    • it's an incremental improvement off of alpha, first of 2016 inventories with projections, defined relative to a date;
    • it will become available as of a certain point in time and can be used for preliminary analyses, but v1.0 would be used for SIP modeling
    • need to include a TSD that describes the strengths and weaknesses of the platform, as it will be used beyond just testing; need a write up that everyone can agree to;
    • what is EPA (and others) planning to do with this beta platform? There are some analyses that need base year in particular in the fall
    • each workgroup to list what was/wasn't included, and what is planned for v1.0
    • need to encourage people to model 2016, knowing that it's not ready for planning; but should convey what will be available in v1.0
    • Will need a TSD to go with the beta; coordination committee could create a template - drafts exist in the charges for the workgroups

Projection Planning and Discussion

  • Julie describes MARAMA's projections approach
    • Develop spreadsheets with factors to grow emissions to the future; internally documented which sources controls apply to, rules they're related to, locations and times they're applied; growth describes factors and areas applied to
    • Set up to have a growth factor for every year of the range of years included in the spreadsheets
    • Dynamic sheets allow you to identify the base and future year to get projection factors between the two years
    • document the source of factors, how they are applied (e.g., by SCC and NAICS), and any rules applied and locations they are applied
    • Takes a few months to put together the spreadsheet
    • Adapt an old template from a previous base year as the starting point fro a new platform
    • Gives states a platform to review and document where changes need to be made
    • Started with the spreadsheet in 2007, adapted for 2011; now adapting to 2016; will be a 6 month process (a lot of state review needed for best results)
    • Developing for all NE states (ME to NC, coast to PA/WV)
    • applied to nonpoint, point, oil and gas, CMV
    • looking to get a webinar on the details, late July/early August
    • EPA reviewed the spreadsheets for 2011 and found them useful; challenge is getting the factors built in, especially for the rules in place; if we can agree on the methods and agree that a national scale tool could be useful
    • Is there interest in other regions to general growth spreadsheets? LADCO, yes
    • This effort is beyond the beta version (v1.0)
    • MARAMA held a webinar with the nonpoint workgroup and invited non-EGU point

  • Beta Cutoff
    • Proposal: October 31 cutoff
    • Will anyone use projection years in November? EPRI's global causes of haze
    • detailed review periods for some sectors (e.g. nonroad) may need to be after beta before v1.0
    • Modeling may not be done until December/January
    • Complete shakeout runs before the platform is distributed
    • Others may use as soon as it is released

Modeling Workgroup Update

  • have co-leads from states - a number of people contacted Zac
  • Wiki page exists - still need to schedule kickoff
  • need to find out what's available for met and IC/BCs
  • need an EPA co-lead

Outstanding Issues

Action Items

  • Zac: create an evaluation spreadsheet template for WG co-leads to use for comparing 2016beta with 2016alpha and 2014v2 (and 2011v6?)

  • Jeff and Doug: consider whether / when air quality modeling for biogenics is feasible

  • Julie: arrange for overview of projection spreadsheets

    • See below for links
  • WG leads: review the modeling workgroup strawman workplan and add/edit, as needed
    • Still looking for comments
    • Julie to send to OTC modeling committee for review

National Call Prep

  • Call is scheduled for 6/20 at noon Eastern
  • Download Slides Template
  • Wiki
  • Send slides to Zac for collation (using this template) by Tuesday 6/19 noon Eastern.
  • Focus of this presentation is the status of the beta version of the inventory: where is the workgroup with the 2016beta inventory and projections? When do you expect to have data to review/release? What are the upcoming milestones?
  • Fill out the overview tab for the Collaborative Inventory Plan and use this to guide the content for the presentation; put all information in this plan and refer people there for more info
  • Add a slide on projection years: why 2023 and 2028, why not 2020; could 2020 be a low priority item? 2020 is not needed for attainment demo modeling, but would be interesting for marginal NAAs for 2015 O3 NAAQS
  • Include a slide for the modeling workgroup; what are they doing and what additional participation will be needed

WG Critical Needs

  • Rail and marine looking for more participation from EPA
  • Suggestion to seek co-lead from OAQPS or regional offices (region 1 for marine or region 9 for rail
  • Alison will communicate to the regions on their next call that the collaborative is going on, and looking for volunteers
  • Alison and MJO directors to reach out to regional offices for participation
  • Modeling workgroup needs members and more scope; suggestion to fold meteorology under modeling workgroup, also include ICBCs; met activities will be to inventory/evaluate what's available for 2016 met data
  • Biogenic workgroup needs a modeling platform to help with the evaluation of the emissions; seeking a 2016 platform; discussion on using the 2015 anthro emissions from EPA with 2016 met as a possibility; Alison will see what it will take to get a 2016alpha platform built at EPA; need to define what will be investigated by the modeling, what are the questions that the workgroups will be investigating through the modeling; the approach taken by the biog workgroup may provide a template/prototype for how other WGs approach modeling for inventory evaluation

Preparing for Beta (Alison)

  • Please fill in the overview tab of the collaborative inventory plan
  • Fill in when beta components will be ready and when the projections will be available; when will there be comment periods

2016alpha nonroad correction and implications for other WGs (Tom/Alison)

  • What does this mean for the review and approval work for the other WGs?
  • Is there sufficient documentation of the process and inputs used by EPA for the alpha datasets?
  • Should there be an “up front” sampling of the 2014 vs. 2016 data inputs to allow comparison before 2016 alpha data were generated?
  • 2016alpha for nonroad was built last year, EPA missed some trends in the unadjusted comparisons with 2014; found that the 2016alpha data were actually 2014 emissions factors run with 2016 met & fuels; NONROAD rerun with 2016 factors to create a new alpha nonroad inventory; not expected that this issue will be relevant for other WGs
  • Remind the WG co-leads about the evaluation steps listed in the inventory collaborative workplan; part of the QA steps for the beta 2016 inventory should be at least state total comparisons back to 2016alpha and 2014v2; seek help from other workgroup members (those not as engaged) to check and comment on these comparisons
  • NE contribution modeling showing that nonroad is projected to be a big deal for future O3 concs.
  • Coordination group (Zac and Alison) to create a spreadsheet template for comparing different inventory versions

Review of making use of the 2023 projections from the 2016 platform (Tom)

Beta vs. v1 / now (whenever there is a robust/complete/representative 2016 platform across all sectors to project from…) vs. in the next couple of years

In a collaborative process, especially for projections, it suggests measurable metrics for quality AND completeness/representativeness across all source sectors and consensus agreement of participants. The process result, even given that many others are using other years for planning purposes, would be better and more defensible if we identified:

  • How good is good enough and why?
  • Individual states have to decide about their moderate SIP submittals and I’m not sure our technical process is specifically addressing what they want/need – is it? Have we asked?

  • Out of time, will cover this on next call

April 11, 2018

Next Call: May 9, 2018 @ 2:00 Eastern

Attendees Zac, Alison, Jim, Sarah, Serpil, Chris, Joseph, Jeff, Mark, Doug, Tammy, Caroline, Susan, Julie


  1. Review action items from March
  2. Follow up on the National Report Out Call (Zac)
  3. Coordination between workgroups (Alison + All)
  4. Creating engagement in workgroups (Zac)
  5. Defining Beta (Alison + All)
  6. Discussion of challenges by workgroup leads (All)


Follow up on the National Report Out Call (Zac)

  • Call went well, but need to allow more time for assembly of full package next time
  • People stayed within their allotted times
  • Get the notes from the call up on the wiki - Zac is working on this action item
  • Add in link to the webinar recording - need to see if LADCO has the recording
  • Follow up on unanswered questions
  • Time of the next national call: noon instead of 1:00 Eastern

Coordination Between Workgroups (Alison)

  • Discussion of where workgroups overlap (e.g., EGU point and non-EGU point splitting) and how to facilitate inter-group collaboration
  • Newly posted data:
    • Comparison report between 2014/2015/2016
    • 2016 point data summaries out there for categorizing into sectors
    • Updates to point need to get into EIS before beta version:
    • data on UNC Google drive are available in larger chunks for easier reassembly:
    • Platforms posted on FTP and Drive will be updated with 2016 alpha point sources soon
    • If there are not resources for both NEI and 2016, NEI should be the priority for states
  • Pressing coordination needed between the point inventory: any changes for the point inventory need to make it in by mid- to late-May, this includes non-EGU point elements like rail yards and ports
  • Need to know information about different types of units to help with modeling these data; need to talk in the workgroups to ensure that all of the fields needed to model the sources are available
  • Examples of workgroups that overlap: fires + non point, EGU + nonEGU point, oil & Gas + non point + nonEGU point, non-road + rail, non-road + marine, non-EGU point + rail
  • All WGs should review the growth factors (i.e., sources of data) used by each sector, to ensure consistency across the inventory

Creating Engagement In Workgroups (Zac)

  • WG co-leads face challenges of inaction by group members and by critical feedback without any suggestions for improvements
  • Need to turn a complaint around into a question or wish, every complaint is a frustrated wish
  • Remind workgroup members that we are balancing best practices and resources. Define best practices (what is possible) and prioritized given resources (what is practical)
  • Given an complaint: respond with, what is a better way of doing X? or reframe with "I wish that..."
  • Be specific about how others have provided state data, and provide timelines; with onroad WG, specified early that states could provide VMT, states then had a target of what they could collect; give very specific inputs of what they could collect/how they could contribute; avoid ambiguity
  • Whenever a state has offered up data for feedback, add them to the agenda
  • Example of where a discussion was taking away from the agenda, WG co-lead moved the discussion offline to work out the issue; set up an avenue for offline discussion if someone (or an issue) is derailing a call
  • Nonroad WG offered an example of where lively discussions on the calls have helped improve the overall process; people have shared their own development approaches, WG leads have taken these insights to the OTAQ non-road development team; discussions have been fruitful to get examples of how others have done things

Defining Beta (Alison + All)

  • How does EPA build a platform given that emissions data are always evolving?
  • How will we know when we have a beta platform? What will be in it, and when?
  • In giving structure to beta, will create a spreadsheet for the WGs to describe what beta will likely include for each sector; describe time constraints on achieving what beta could be; what we want in it and when we think we’ll have it
  • Example non-road: want an improved version of non-road with growth factors but it may not be possible to get these growth factors in by July
  • Collaborative is a unique effort: have a product in mind and an idea for the date, but no hard deadline on producing the platform
  • Building block approach: people can compile sector versions into a platform on any time frame
  • Suggestion that we just pick a date and say that everything available at that time is in; need to have a platform that can be comparable between modeling groups
  • Need to look at schedule for prospective deliverables from the WG leads before deciding on this beta freeze date
  • Action: Alison puts together spreadsheet
  • Action: WG leads fill in what they want in the beta platform and when they think it will be ready
  • Concern about the projections and getting these into beta
  • Need a centralized table/schedule for data review
  • Will be some sectors where there are choices for modelers., e.g. biogenic: MEGAN and BEIS, EGU: EPA engineering and ERTAC; modeling workgroup will discuss issues related to compiling a modeling platform where there are multiple choices for certain sectors
  • Documentation needs to go out with beta versions of the data; specification sheets are proposed to help: how it was built, data sources, how it is done; comparisons between different versions
  • Projections: which data set to use for the comparison: EL for 2028, and EN for 2023; include state totals in documentation

Challenges (All)

  • On-The-Books rules are being rescinded and/or reworked - how to handle these changes when building inventory projections?
  • Stick with the on-the-books and only make changes when a rule is finalized
  • Need to tease out rules that may be on the chopping block and make it easy to take these rules out, if needed
  • Control packets could be made by rule, but it complicates the modeling effort

Action Items

  • Strawman on modeling workgroup
  • Post notes and, if possible, recording of webinar
  • Zac and Alison to follow up on unanswered questions
  • Alison to post updates to distributions on FTP and Drive to include 2016 point sources
  • Alison to post Google Drive spreadsheet to prepare beta
  • Workgroup leads fill in the beta spreadsheet

March 13, 2018

Note alternative date for March meeting

Attendees Zac, Alison, Serpil, Doug, Mark, Jeff, Julie, Tom, Mary, John, Sarah, Chris, Joe, Caroline


  1. Review plan for national outreach call on 3/15 (Zac, Alison)
  2. 14-15-16 Platform Update (Alison)
  3. Discussion of challenges by workgroup leads
  4. Registration from May Training in RTP from Sally Dombrowski


National outreach call review

  • workgroup leads to prepare a few slides
  • Keep workgroup presentations to 7 minutes so all groups have time to report out; see Alison notes on what to include in the presentations:
    • Intro to workgroup – co-leads, List of members
    • Structure of workgroup (if any sub-groups)
    • Information on level of participation
    • Planned methods and work focus areas
    • Likely contents of beta inventory
    • Data that might become available for comment and schedule for this
    • High-level plans for projections (more about this next time)
  • Discussion on need to introduce the point source inventory development approach; Alison will create a slide on the general point source release to add into the intro slides
  • Need to include a wrap up slide that broadcasts where to find notes and when the next meeting will be (June 20 @ 1:00 EDT)
  • Plan for handling of questions
    • We will direct attendees to ask questions through the webinar client; Alison and Zac will facilitate the discussion, and if time will pose a couple of questions while on the call; all questions will be addressed after the call on the wiki
    • Julie will put together a slide that describes how to ask questions through the webinar client
  • Discussion on when/who will do the 2016 air quality modeling for evaluating the 2016 inventory products, and sensitivities
    • LADCO will do 2016 runs, but no solid scope yet
    • Need to develop a wishlist of possible sensitivities: biogenic (MEGAN vs BEIS), with/without fires, projection approaches, source apportionment...
    • What is the best forum for this discussion? InterRPO data share group? probably need an emissions modeling workgroup to discuss issues with processing the 2016 data

14-15-16 Platform Update (Alison)

  • Alison is working on the platform component table
  • EPA is working with UNC to post a full archive of each platform to a Google Drive for distribution; in addition to scripts, will include sample SMOKE outputs for testing

Challenges (all)

  • Jeff: participation is good in the biogenics workgroup; two groups: one that follows and adds a little here and there and another small group that is doing most of the work; co-leads working to make sure that everyone has current data and information in front of them to drive the process forward; don't know what the dynamics of the fire and oil and gas workgroups will be yet
  • Julie: trying to head off people who are getting ahead of the process and catastrophizing about the schedule; co-leads have had to circle people back to the leadership to address some "alarmist" requests about involvement in the group
  • Tom: some sectors have relied heavily on contractor support (oil/gas, fires) in previous inventory efforts and it's not clear what the path forward will be without this support; Jeff has worked to secure possible support from USFS to work on the fire inventory; possibly some resources to contract ERG to help with oil/gas
  • Caroline: also dealing with varying levels of engagement; a lot of suggestions that the methods be changed but no input on how they should be changed; challenge to get people to move beyond criticism and into more substantial contributions to the process; looking for ideas
  • Mark: make more of an effort to accommodate the people who are doing the real work
  • Caroline: is there still interest in forming an aircraft subgroup within non-EGU point? there was originally discussion about this group, but now questioning whether there is enough momentum to support it; EPA and MARAMA are doing some work in this area
  • Joe: nonroad group is sorting out what states and MJOs have done in this area that can help the process; set up an approach to review two subsectors each call, seems like a good approach

MOVES2014b Release

  • EPA planning a release of MOVES2014b in the summer that will include updates to nonroad database: emissions factors, projection information, engine populations

    • Status: Pending - best to do after alpha version is available
  • For Future consideration: Success metrics.

Check in on meetings to-date

  • Most workgroups have met. First fire workgroup meeting is scheduled for March 1. Oil and gas plans to have a meeting in early March. A roadmap is being developed for the WRAP effort. An outline will be developed regarding how to leverage that effort for the 2016 collaborative and with ideas for building 2016. International group had a discussion via email. This group may benefit from EPA regional staff involvement. Alison will probably schedule a call after new Mexico data are available to review that and other issues.

Remind co-chairs of their charges: starting with alpha, and facilitating development/innovation toward a beta version

  • Zac described parallel efforts in the workgroups: 1) production of usable products for alpha, beta, v1; and 2) development/discussion of longer-term improvements and innovations to be used for later versions of 2016 and 2017 inventories. The goal is to leverage a larger group of people involved in this effort to develop new methods and data. It could be difficult to balance the two efforts, so workgroups will need to prioritize. The first step is to evaluate the existing 2014NEIv2 and 2016 alpha data. The workgroups will then need to figure out what is doable for the beta and v1 versions, given the size and level of engagement of the workgroups, and work towards accomplishing those steps.

  • Tom brought up that it will be important to clarify the components of the alpha platform: which are from 2014 versus 2016. He suggested something similar to what Pat Dolwick had provided would be helpful. Additional documentation will be important including documentation on emissions factors, spatial allocation, temporal allocation, speciation, and plume rise.

  • Zac agreed that some level of documentation for the inventories and that the beta version should have more data for 2016. Documentation would need to specify which sectors don't have actual 2016 data.

  • Tom wanted clarification on why we have an alpha version and who is going to use it.

  • Mark described that it often takes a while to get the desired model performance, so the alpha version will allow LADCO and others to get started modeling their regions so that issues with meteorology and other aspects of the platform can be addressed. The beta version is a step along the way to the final version and it gives us an opportunity to have a first set of projections. Zac agreed that the alpha is to shake out modeling with the new year, not for planning purposes and that beta would be an improvement.

Update from EPA on NEI14v2 and planned 2016 inventory/platform releases

  • See NEI2014v1 Pie Charts Courtesy LADCO. Note that 2014NEIv2 should be live on the NEI website by President's Day.

  • EPA is planning a coordinated release of 2014, 2015, and 2016 alpha that will include the rest of the input data needed for emissions modeling and scripts by late February or early March. EPA will not have fully processed AQM-ready emission inputs or AQM outputs for these cases, but others can prepare their own. The scripts will be tested prior to release and some sample outputs for selected days can be provided. These distributions will include MOVES emissions factors, SMOKE-processed onroad mobile emissions, and biogenic emissions for each year.

  • For 2014, only NATA/HAPs simulation/scripts will be available from EPA

  • For 2016, EPA will provide year-specific data for onroad mobile, nonroad mobile, fires, biogenics, oil and gas, and point; the nonpoint sectors will mostly be for 2014

  • Collaborative may be forum for creating a unified set of SMOKE scripts to use for processing the different modeling years

  • Comments were made that the platform table would be helpful to clarify what is in this release.

Discuss/brainstorm challenges being faced by workgroups

  • We didn't have time to get to this item, but we encourage WG leads to email Zac and Alison with any challenges they may be having.

Outside involvement in the collaborative: who else can be involved and to what extent

  • University researchers expressed interest in being involved. We believe that the workgroups would become unwieldy with external parties that could have different agendas. The workgroups should primarily consist of State/local/tribal/regional organizations, but each workgroup has latitude to consider what makes sense for their group. For example the rail workgroup has included rail organizations from its inception, and workgroups may want to have invited speeches from researchers or contractors.

Upcoming meetings

  • Fed/State Collaborative: Thursday 2/22 @ 11 Eastern (see attached draft presentation on emissions). Mary pointed out that we should be sure to include some background as some on this call may not be very familiar with the origin of the effort. Alison provided a draft presentation - please send comments if you have them.

  • Next month’s broader meeting: need to determine mechanism and call-in – hold as a webinar? It seems that we may want to schedule this on a separate day/time/mechanism from the regular call. Perhaps as a webinar in late March. Details to be worked out.

Action Items

January 17, 2018 Update

Reach out to your Workgroup Members

Action requested:

  • Please send an introductory message to those who have volunteered for your workgroups. Let them know where to find your workgroup page on the Collaborative WIKI and also point them to the top level collaborative WIKI page.
  • Please update your WIKI page to include your workgroup charge and your workgroup member names, but not emails (to help prevent SPAM).
  • Internally, you will also need to maintain lists of the workgroup emails so you can send your notices and meeting notes. You should start with the names on the spreadsheet Julie sent November 30. Since then, a few other messages were received and forwarded to co-leads.
  • If you update your list on the Wiki, we’ll all be able to see and cross-check that all of the members who want to participate have been added to the groups.
  • If you are piggy-backing your meetings with other existing workgroups, please be sure you explain that to your new members and you get them added to the existing workgroup invitee lists.

    • Success Metrics - How do we measure workgroup success? Are there milestones and required products? Are these consistent across workgroups?
    • Accuracy, Utility, and Value Weighting - What do these mean?
    • Review and distribution of specification sheets to others outside of the collaborative - at what point do we distribute the spec sheets? after the alpha versions of the inventories? just before/after the beta versions?
    • Sharing information outside of the Collaborative under “Representative Review and Comment”:

Each workgroup will provide documentation of work products for ongoing review and assessment by states and tribes across the country, and accept and record all comments received on each work product. Further, a more complete process for sharing information about the 2016 EMP with others outside the collaborative and receiving input from outside stakeholders will be defined by the coordination committee. For example, sector specification sheets and documentation from workgroups could be posted for review and comment by stakeholders outside of the 2016 EMP Collaborative for the 2016 alpha, beta, version 1.0, and v1 projections.

  • Specification sheets are key for transparency and documentation - try to update as progress is made
  • Concerns about access and permissions discussed: VA and CA known to not have access to G-Suite, likely others; workgroup leads will need to figure out work arounds
  • Bear with the coordination leads as we work through the initial permissions and access issues to the resources laid out for this process
  • The process and resources are suggestions, not prescriptive
  • Need MJO/state co-leads for non-EGU point and non-road
  • EPA will likely just lead the Mexico/Canada group
  • Alison gathering 2016 data that they already have in-hand for the workgroups. Currently have on-road, non-road, fires, biogenics for 2016; most of the non-point sectors they have are for 2014
  • Make sure to distinguish between the 2016 and 2014 data; 2014 will be labeled 2014v2

EPA 2014v2 status

  • onroad, nonroad, point fires (wild, rx), point are ready; nonpoint is still being worked on, hopefully ready in January
  • Is there a reference or resource for EPA 2016 global modeling for ICBC data? EPA can share the input data and status of this effort. Would like to see a presentation (webinar) on the hemispheric modeling, when available (several months away)
