Rodger lead the group through the WG5 powerpoint presentation linked above. Key topics included an update on the site-to-site correlation analysis, maps showing monitoring site locations and relevant spatial layers aimed at helping the group assess potential regions that are not represented by monitors in the current network. A final set of slide focused on analysis of WAQS 2011b emissions and the intersection of monitors with PM, NOx and VOC emission sources, particularly for O&G sectors.

Attendees: Attendees: Barkley Sive (NPS), Kevin Briggs (CDPHE), Chad Meister (BLM-CO), Doug Kuenzli (MTDEQ), Brad Schultz (SDDENR), Gregory Harshfield (CDPHE), Cara Keslar (WYDEQ), Debbie Miller (NPS), Rita Bates (NMED), Zac Adelman (UNC-IE), Roman Szkoda (NMENV), Rodger Ames (CIRA), Tom Moore (WESTAR/WRAP)

Action Items

Rodger: update O&G well locations with recent WOGCC data.

Rodger: add spatial layers of Indian lands to the presentation maps.

WG participants are encouraged to provide updated information regarding O&G activity in their states. Such information could be updates O&G well locations, leasing information, and recent changes in monitor status.

WG participants are also encouraged to review the maps in the PowerPoint and help identify gaps in the current monitoring network (particularly with respect to current and/or planned O&G development)

The morning of April 20 was suggested for the next call. Rodger will send out an announcement to the group.
