Southern Ute Indian Tribe

Air Quality Division

Jeremy Wade Shockley | Southern Ute Drum


The Southern Ute Indian Tribe’s Air Quality Division is dedicated to ensuring that the air on the Southern Ute Indian Reservation remains clean and safe for Tribal Members and residents, now and into the future. This is being done through monitoring of air quality, permitting and compliance monitoring of large pollution sources, emissions inventories, and continued research of air pollution and its sources.

Ambient Monitoring

The Air Quality Division maintains three State and Local Air Monitoring Stations (SLAMS) to monitor air quality on the Reservation. The air monitoring station Ute 1 is located just north of Ignacio, Colorado while the second station, Ute 3, is located off of Colorado State Highway 550 north of Bondad, Colorado. The third station, a mobile monitoring station, is located at Lake Capote on the east side of the Reservation. All stations adhere to Environmental Protection Agency (EPA) SLAMS quality assurance guidelines and data is reported to the EPA Air Quality System for National Ambient Air Quality Standard comparison and EPA’s AirNow website.

Title V Operating Permit Program

On March 2, 2012, the United States Environmental Protection Agency approved the Tribe’s Title V Program application, granting the Tribe full authority to implement and administer its 40 CFR Part 70 Operating Permit Program for Title V sources within the exterior boundaries of the Reservation.

Environmental Commission

The Mission of the Environmental Commission is to oversee the development and implementation of a comprehensive and effective program for the protection of air quality throughout the Southern Ute Indian Reservation.

Reservation Air Code

The Reservation Air Code (RAC) was approved by the Southern Ute Indian Tribe/State of Colorado Environmental Commission (Commission) on November 12, 2008, and became effective on the March 2, 2012 approval date of the Southern Ute Indian Tribe’s Part 70 operating permit program.

On November 14, 2012, the Commission approved RAC Article II, Part 2 and Part 3 to incorporate certain New Source Performance Standards and National Emission Standards for Hazardous Air Pollutants. On July 8, 2013, the EPA approved delegation to the Southern Ute Tribe to implement and enforce New Source Performance Standards and National Emission Standards for Hazardous Air Pollutants as a direct final rule. This rule became effective on September 6, 2013.


Emissions Inventory

The Southern Ute Indian Tribe Air Quality Division prepares emissions inventories for air emission sources within the Reservation boundaries. Comprehensive inventories of emissions from all quantifiable point, nonpoint sources, mobile, and fire events are completed every three years and inventories of large point source emissions are completed annually.

For more information about the emissions inventories and to view comprehensive and annual emissions inventory reports prepared by the Southern Ute Air Quality Program, please visit the Emissions Inventory web page.
