This program is conducting air monitoring at eight tribal sites throughout Oklahoma. At three of the tribal sites, ITEC is monitoring for criteria pollutants and meteorological parameters. These pollutants are carbon monoxide, ozone, sulfur dioxides, nitrogen oxides and particulate matter. The meteorological parameters are temperature, humidity, precipitation, wind speed and wind direction.

At the eight sites, fine particulate matter is monitored as part of the EPA's National PM2.5 Network. Other program initiatives have included: GIS mapping of tribal trust lands; inventorying major and minor air sources for the ITEC member tribes; reviewing the state of Oklahoma's new and/or modified major source permits; and providing technical assistance and training to the member tribes for various clean air aspects.

The Cherokee Nation Clean Air Program consists of an array of air pollution monitoring devices sited on Cherokee tribal land. There are currently four continuous ambient air monitoring stations monitoring for criteria pollutant emissions and meteorological data. These sites are located at

• Newkirk (Chillocco School)

• Pryor

• Stilwell CastNet Station

• Tahlequah

Each station monitors for similar parameters which include: Ozone, Carbon Monoxide, Oxides of Nitrogen, Sulfur Dioxides, Particulate Matter (PM2.5 & PM10) & meteorological parameters.
