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

Highlights from Last Call
• 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)

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 NMb. UA13 Roan Plateauc. 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

Evaluation of Potentially Underserved Areas
• See updated table in: UA_ProsCons_17Jan2014.docx
• Need to rank UAs (H, M, L or 1,2,3…13)Potentially Underserved Area
Pros Cons Add’l Comments Rank*
UA1:
Saguache-Monte Vista-Alamosa
Great Sand Dunes NM on eastern boundary (but at higher elevation)
Far from any existing monitoring sites
Some areas of elevated non-fire O3 impacts predicted, including areas below 8,000’ (WestJump modeling)
Isolated; No significant existing sources or major population centers in immediate vicinity
Far from any emissions sources Generally low O3 contribution from
anthropogenic sources predicted (WestJump modeling)
J. Korfmacher (1/13/14): Not a priority for a number of reasons, but a very interesting area topographically: big, broad valley that may be subject to the inversions and snow cover in the winter that characterize Pinedale and Vernal. A valley-floor monitor for a season or two might be very useful.
L
UA2: East-Central WY
Downwind of major point sources (Dave Johnston and Laramie River Station)
Minimal O&G development Low NOx emissions density Low non-biogenic O3 impacts
predicted (WestJump modeling)
J. Korfmacher (1/13/14): On and around Thunder Basin NG. Probably not much happening out there--very few sources upwind and very well-mixed. Maybe MedBow or R2 have an interest in monitoring around the Thunder Basin.
L
UA3: Medicine Bow – Saratoga
Downwind of CDC development area
Not well represented by higher elevation Centennial monitor
Minimal O&G development No major sources Generally low anthropogenic O3
impacts predicted (WestJump modeling)
USFS (D. Miller) has expressed interest.
J. Korfmacher (1/13/14): Not too far from my Snowy Range field site, so it wouldn't be too big of a deal to manage/maintain. Some potential O&G upwind precursor sources.

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
Area Informal Summary Assessment Recommended Rank [DRAFT]
UA13: Roan Plateau Downwind of O&G developments and far from Rangely; USFS suggests Douglas Pass site
3
UA5: Dinosaur East Side Of interest for several reasons and commentators have suggested high priority but USFS may have difficulty servicing this remote location
3
UA12: Kremmling Area Mostly high elevation; downwind of White River O&G development; low elevation areas not well represented by current network; potential USFS Holy Cross site in southern end and DRI Storm Peak in northern end
2-3
UA2: East-Central WY Considered high priority by WY DEQ due to future development plans; considered low priority by other agencies; mobile monitor in place 2013 - 2014
3 (based on WY DEQ analysis)
UA3: Medicine Bow – Saratoga
Potentially downwind of large O&G development but WestJump predicts low anthropogenic impact; may be manageable by USFS
2
UA9: Dove Creek North Side May be reasonably well represented by existing sites but there is potential for future development in the area (Mancos and Paradox)
2
UA4: Central West WY Some on-going development to the south but otherwise of lower interest; considered medium priority by WY DEQ
1-2
UA6(Caineville-Hanksville), UA7(Green River-Westwater), UA8(Blanding Area)
Long way from any existing assets; UDAQ suggests existing sites are reasonably representative of UA6, UA7 and UA8
1
UA10(Delta-Montrose), UA11(Black Canyon of the Gunnison)
Minimal evidence of ozone greater than background; Near otherwise unmonitored Class I areas (Black Canyon of the Gunnison and West Elk); Easy access via US-50
1
UA1: Saguache-Monte Vista-Alamosa
Low priority based on ENVIRON analysis and other comments received; 1
