  3. Outline analysis phase of WAQS monitoring network assessment

Minutes

Attendees: Bo Call (UTDEQ), Rebecca Matichuck (EPA), Cara Keslar (WYDEQ), Barkley Sive (NPS), Doug Kuenzli (MTDEQ), Barb Regynski, Brad Schultz (SDDENR), Kevin Briggs (CDPHE), Mike Barna (NPS), Gordon Pierce, Gregory Harshfield (CDPHE), John Vimont (NPS), Chuck Hyatt (NDDH), Will Vicars (CDPHE), Rodger Ames (CIRA), Dustin Schmidt (CIRA)

Rodger Ames started the call with roll call, then went through the ppt for the call (#6, above). The first item a review Nov. -Dec. Working Group activities. During Nov. Rodger solicited and gathered feedback from state air agency representatives on current monitoring sites and planned chnages for their states. Feedback on two documents (#s 3 & 4 above) was received from Colorado, North Dakota, South Dakota, and Wyoming. Montana provided their 5-year assessment for review.

The need to gather monitoring site information form federal agencies and tribes conducting monitoring was identified, as was the need to clarify WAQS funded monitoring. Just before the call, John Vimont provided information on sites funded through NPS on behalf of the WAQS, and slide 3 in the ppt was updated accordingly. Of the six sites funded via 3SAQS, one was discontinued (Walden-CO), one transferred from NPS to UDEQ (Escalante-UT), and one transferred from UDAQ to UBLM, then to a research site operated by Seth Lyman's group at Utah State.

Slide #4 showed a list of FS operated sites obtained from a recent AQS data pull. Debbie Miller updated the group on the current status of the monitoring sites, and will follow up with an annotated list when she returns from vacation on 12/12. DM noted that Holy Cross and Deadman Pass sites indicated on Slide #4 were yet to be installed.

Slide #4 also included "new monitors" per the 3SAQS network assessment. Gordon Pierce noted that the Dinosaur site is a relocation of the Rock Springs site, and that they (CDPHE?) has an interest in retaining the Shamrock site that is currently jointly operated by FS and COBLM.

Rebecca Matichuck and Bo Call offers assistance in reaching out to Tribes conducting AQ monitoring in their respective regions.

Rodger presented a preliminary outline of analyses for the WAQS assessment. He suggested generally following the approach employed by the state of Colorado in their assessment for area and population served analyses; confining emissions analyses to using WAQS 2011b gridded emissions to represent emission sources; and surveying this working group for projected emissions changes related to new and/or ramping up/down of O&G development areas. As for AQ representativeness, a list of analyses was presented in slide #5, and Rodger offered his opinion that the removal bias analysis may not be useful for the WAQS assessment (Will Vicars agreed).

Final slides outlined next steps and a tentative (and perhaps ambitious) time were shown to conclude the call. After the call, Dustin Schmidt noted that in AQ analysis that compare site DVs to modeling data, exceptional events will need to be accounted for in preparing 2011 and projections based on modeling output. Methods for filtering exceptional events should be discussed on a future call.

Action Items

  • clarification on WAQS funded sites (3 of original 6 3SAQS sites)
  • outreach to federal agencies and tribes on monitoring activities.activities
  • follow up with state air agency representatives on current monitoring activities (where necessary)
  • continue data gathering and begin data analysis
  • next working group meeting in early Jan., 2017
