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.
