Rocky Creek Air Monitoring Site

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

To learn about other air monitoring sites the department operates as part of the state's ambient air monitoring network, visit Air Monitoring Sites.

Ozone Pollutant

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