  • 2 other sites likely to be over with 3 complete years
  • All within existing NAA

 3 sites violating the 75 ppb NAAQS  Early ozone forecasting notifications to

industry for voluntary emissions reduction actions may have reduced ozone levels

 “Clean data year” with 2 definite smoke-

influenced days removed

  • Exceptional events package for 9/2 and 9/4 will be

developed and submitted to EPA

  • No plans to develop additional exceptional event

packages as will not have any impact on designations

 Continue advance ozone forecasting in 2018  Continue APCD precursor monitoring at 2

sites

  • Denver – CAMP = urban influence
  • Platteville = Oil & gas development influence

 Photochemical Air Monitoring Site (PAMS) in

NAA to be operational by June 1, 2019

  • To be located at Rocky Flats-N site

 Continue summer ozone studies in different

areas

  • 2015 = Pueblo area
  • 2016 = Grand Junction area
  • 2017 = Denver to Continental Divide
