The department established the Rocky Creek station in 2002, two years after assessing its ozone network and outlining its plan to expand monitoring. The air monitoring station lies north of the Kansas City downtown area and west of the department's Watkins Mill and Liberty monitors. It helps characterize ozone concentrations downwind of the Kansas City area; determine ozone exposure for the Kansas City metropolitan statistical area (MSA) and monitor attainment of the ambient air quality standards. 


Ozone Pollutant

The primary National Ambient Air Quality Standard for ozone is 0.070 parts per million averaged over eight hours (annual fourth-highest daily maximum 8-hour concentration, averaged over three years). The federal ozone season for monitoring runs from March 1 to Oct. 31.
