Clean Air Program

With four air monitoring sites located within tribal jurisdictional boundaries in Oklahoma, the CNEP Clean Air Program operates one of the largest tribal air monitoring networks in the country. Criteria pollutants being monitored include ozone, carbon monoxide, sulfur dioxide, nitrogen oxides, and particulate matter. Meteorological parameters monitored include temperature, humidity, wind speed and wind direction, and precipitation. They also operate a mobile monitor that rotates to various tribes and pueblos within Region 6; it is equipped to monitor ozone, particulate matter, and meteorological parameters. The Clean Air Program participates in national monitoring programs such as CASTNet, IMPROVE, the Mercury Deposition Network (MDN) and the Ammonia Monitoring Network (AMoN).
