  11. Thunder BasinOzone measurements and corresponding images when wildfires burned in northeast Wyoming

  12. Thunder Basin July 5, 2001 12:00 pm SVR = 87 km O3 = 68 ppb 15:00 pm SVR = 59 km O3 = 77 ppb

  13. July 19, 2002 10:15 am SVR = 130 km O3 = 78 ppb 11:45 am SVR = 54 km O3 = 86 ppb

  14. July 19, 2002 (12:00-12:45 pm) SVR = 23 km O3 = 88 ppb

  15. July 19, 2002 (3:00-3:45 pm) SVR = 58 km O3 = 96 ppb (highest O3 value in 2002)

  16. Future Plans for WDEQ Ozone Monitoring in Wyoming • Existing Monitors: WDEQ plans to continue monitoring at these sites. • Proposed Monitoring: The Legislature is reviewing a request for funding for monitors in the following locations: • Jonah Field: Area of oil and gas development outside of Pinedale • Wamsutter: Area of oil and gas development in the south-central area of Wyoming • Newcastle: Downwind of coalbed methane development, on the border of South Dakota
