  2. Today’s Agenda • Review discussion from 1/10 call • Provide summary of information received since the 1/10 call • Gather additional information, comments and suggestions • Discuss potential recommendations • Get ready for 24 January call

  3. Monitoring Site Classification Highlights from Last Call Potential 3SAQS Sites Starting Network • Site classification method • Step 1: List of “permanent” and “non-permanent” sites • Step 2: Non-Permanent Class A vs Class B sites • Review Class B sites and potentially underserved areas (UAs) Step 1: Permanent Site? Yes Permanent Sites No Non-Permanent Sites Yes Retain (Class A Site) Step 2 : High value location? Monitoring Network Objectives No Consider Moving (Class B Site)

  4. Input Received Past Week(see new map, revised site spreadsheet and revised UA table) • USFS (J. Korfmacher and D. Miller) • Changes to “permanent” vs. “non-permanent” site list • Comments on Class A vs. Class B non-permanent sites • Comments on UAs • UDAQ (P. Barickman) • Comments on Class A vs. Class B non-permanent sites • Comments on UAs • WY DEQ (C. Keslar) • Potential funding problems for Hiawatha and Campbell Co. sites; move to “non-permanent” • A temporary monitor is currently located in East-Central WY (UA2) for 2013 - 2014 • Comments on UAs • CDPHE (G. Pierce) • Move Pawnee Buttes to “non-permanent” • Palisade and Aspen considered “permanent” • Lay Peak to stay put through 2014; possible move in 2015? • Walden will operate through at least 2014 • Recommended high priority UAs (in order): a. UA5 East of Dinosaur NM b. UA13 Roan Plateau c. UA12 Kremmling as this area had some issues with air quality when the LP waferboard plant was in operation. It is unknown what impact the current pellet facility might have, but the area is subject to deep inversions. d. UA9 Dove Creek

  11. Reminder:3SAQS Monitoring Network Objectives • Provide adequate spatial coverage of study area • Monitor locations with O3 close to or above NAAQS • Monitor locations downwind of existing or planned future development areas • Monitor Class I and sensitive Class II AQRV impacts • Characterize background O3 • Provide data for model performance evaluation (O3, PM and precursors)

  12. Next Steps – Jan. 10th through mid-Feb.
