Agenda

  • Plan for next 3 monthly calls (T. Moore and J Vukovich)
    • Today = point sources
    • July call = future year projections discussion/subgroup formed
    • Aug call = future year projections: recommendations for beta version
  • Update on 2016 point source oil and gas (Vukovich, Moore and Snyder)
  • Gathering info on point sources (Permit info/Registration/caps/etc) (T. Moore)

  • Update on possibility of using Oil and Gas Tool for 2016 (Vukovich, Snyder and Moore)
    • Review availability of 2016 data from states that have directly submitted non-point data in the past
      • Alaska, California, Colorado, Michigan, New York, Michigan, Ohio, Oklahoma, Pennsylvania, Texas, Utah, Wyoming, others?
  • Next workgroup call is Monday July 9th, 2PM ET

Minutes/Notes

  • Content for the 3 workgroup calls were briefly discussed.
  • List of NAICS codes is changing in 2017; must continue to realize this when examining 2016 point source emissions
  • NAICS 211112 for Natural Gas Liquids Extraction may not fall into the "upstream" emissions bin
  • Roslyn Higgin (NM) mentioned that the first 4 NAICS codes in the "upstream" bin in the meeting's pdf presentation are not "upstream" sources according to their state's inventory
  • Recommend looking at NAICS-SCC combinations
  • Tom Moore present template for gathering point source info: permitting, registration, etc.
  • After workgroup discussion, Tom Moore volunteered to modify the template based on that discussion
  • Using the Oil and Gas Tool to generate non-point emissions estimates for 2016 is looking likely occur
    • Discussion occurred where Jennifer Snyder explained her recent email requesting if states wanted to possibly use the emissions from this tool or if they had state-specific 2016 estimates or if they want to just pull forward the 2014NEIv2 inventory to 2016.
    • NY indicated that some adjustments were made to the Oil and Gas tool for their state for 2014NEI; need to make sure those adjustments are used in 2016
    • AK indicated concern with trying to come up with detailed 2016 Oil and Gas tool input data; EPA responded by saying that it is understood that this is a non-NEI year and it may not possible for states to do this. AK will likely just pull forward their 2014NEIv2 estimates to 2016.
    • Jennifer Snyder (EPA) continues to gather up responses to her email dated June 6, 2018
    • NM mentioned a recent email regarding point vs. nonpoint O&G sources for their state. Workgroup co-leaders will meet with NM soon about this.

Action Items

  • Compile all NAICS-SCC combinations for oil and gas point source inventory(Vukovich)
  • Make any edits to the point source info xls presented during this call after discussion and make it available to all workgroup members via a Google document (Moore and Vukovich)
  • Workgroup co-leaders meet with NM (Roslyn and Mark Jones) about NM-specific email concern regarding point vs. non-point sources in their state

Agenda

Minutes/Notes

  • Majority of call consisted of presenting the 2016 point source oil and gas inventory (pt_oilgas) after getting updates for 2016 emissions for some facilities
  • Upstream, Mid-stream and downstream sources and their definitions were discussed
    • NAICS codes do not always give clear definition of if a source is upstream or other
    • Previous inventory studies have found exceptions where compressor stations with "upstream" NAICS was actually involved with transmission activities which could be mid-stream
  • It is important to classify upstream or midstream or downstream because of method/activity data used for growing emissions into future
    • AEO production forecast data can be used for growing upstream sources while maybe consumption forecasts for downstream/mid-stream
    • Perhaps no growth for mid-stream is possible in some cases
    • Members suggested applying growth by NAICS
      • may need to make exceptions but just focused on major emitters
  • Subject of possible double-counting situations with point and non-point sources were discussed
    • Oil and Gas Tool has an option for states to subtract out their point source emissions from non-point inventory
    • If a 2016 Oil and Gas Tool inventory is generated, must keep track of upstream sources in point and non-point inventories
    • WY and CO gave examples of the QA and process they go through to submit point sources and non-point sources for oil and gas.

Action Items_

  • Post pt_oilgas emissions summaries with year 2016 emissions update (Vukovich)
  • Co-leads to generate outline for next 3 calls to get to beta version of inventory ( Moore and Vukovich)
  • States/MJOs/others to quality assure the new point source inventory for 2016 point source (ALL)
    • Are the major emitting facilities classified appropriately by NAICS code? Exceptions?
    • Are the changes from 2014NEIv2 to 2016 levels OK?
    • Provide feedback by JUNE 4, 2018
  • All members continue to think about how best to grow and control emissions to future years 2023 and 2028 (ALL)
