Southern Ute Tribe - Air Quality Program Development

Air Sciences continues to work with the Southern Ute Indian Tribe to develop one of the more sophisticated and unique Air Quality Programs in Indian Country. From building essential technical tools (emissions inventories, Operating Permit training) to helping to frame unique inter-governmental cooperation with the State of Colorado, Air Sciences has worked hand-in-hand with the Tribe. Some key aspects of the Southern Ute Air Quality Program are:

  • Preparation of a Feasibility Study for an Operating Permit Program. This assessment prepared by Air Sciences demonstrated that the number of major stationary sources (as defined by the Operating Permit Regulation in 40 CFR Part 70) and the quantity of regulated pollutants (criteria pollutants and hazardous air pollutants) were sufficient to justify a self-sustaining operating permit program delegated to the Tribe under 40 CFR Part 70.

  • Creation of the Southern Ute Tribe/State of Colorado Joint Environmental Commission. Due to unique jurisdictional issues, the Tribe and State worked together for many months to craft an agreement that would allow for the smooth transition of permitting authority to the Southern Ute Tribe. Currently, the Tribe and Air Sciences are working with the Joint Environmental Commission to prepare the necessary documents for the Tribe to apply to the US EPA for delegation of an operating permit program under 40 CFR Part 70.
