About the CTUIR Air Quality Program

The CTUIR Comprehensive Air Quality Program Office of Air Quality is a program within the Department of Science and Engineering. Recognizing that air is one of our most important natural resources, the goal of the CTUIR CAQP is to ensure clean air on the UIR by developing a program to assess, monitor, regulate and remedy both indoor and outdoor air quality.

The CTUIR air quality program began in 1997 with the hiring of an air quality coordinator. This was in response to the planned incineration of 13% of the United States Chemical Weapons Stockpile at the Umatilla Chemical Depot, near Hermiston Oregon. Since then the CTUIR and EPA have worked together to address air quality through the development of and air emissions inventory of the Umatilla Indian Reservation and investigating indoor air quality on the Umatilla Indian Reservation.

As of January 1, 2007 the CTUIR is administering smoke management rules on the reservation.
