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 Stilwell site has been designated as a rural NCore site, and a Tekran continuous mercury analyzer is operated at this location. The Clean Air Program also participates in national monitoring programs such as CASTNet, IMPROVE, the Mercury Deposition Network (MDN) and the Ammonia Monitoring Network (AMoN). Past program initiatives have included GIS mapping of tribal trust land, creating an inventory of major and minor sources for ITEC member tribes, reviewing new and/or modified major source permits that have been issued by the state, and providing technical assistance and training to the member tribes related to air quality monitoring.
The CNEP Air Program received a 2006 Clean Air Excellence Award in the category of Community Action. The award ceremony was held in May 2007 in Washington, D.C. at the National Museum of the American Indian.
