The Air Quality Program's purpose is to protect tribal member health and resources from ambient and indoor air pollution. Efforts are under way to build program capacity, propose and implement air quality regulatory tools, install and maintain a baseline air quality monitoring project, and assume air quality management authority for selected sections of the Federal Clean Air Act from the United States Environmental Protection Agency (EPA) under the Tribal Authority Rule (TAR).
In 2007, the Air Quality Program completed an Air Quality Assessment for the Tribes' Ancestral Airsheds. The purpose of the Air Quality Assessment was to improve the Tribes' understanding of current air quality conditions and determine whether air quality risks from criteria pollutants and/or air toxics exists.
In 2008, the Air Quality Program was successful in securing funding through EPA Region 10 under Section 103 of the Federal Clean Air Act. This funding provided the Air Quality Program with an opportunity to install a PM 2.5 and Meteorological Monitoring Project on tribal lands near the Tribal Administartion Offices. Technical assistance was provided by of the Tribal Environmental Exchange Network (TREX) for station installation and data management. A Quality Assurance Project Plan (QAPP) was developed for the PM 2.5 & Meterological Monitoring Project and was approved by EPA in October 2009. Meterological monitoring was initated on October 2, 2009, and PM 2.5 monitoring was initiated in September 2011.
The Air Quality Program secured a "Teatment in the Same Manner as a State" or TAS authorization for Sections 105 and 505(a)(2) of the Federal Clean Air Act. TAS status provides the Tribes with an "affected status" in regards to the state and federal air quality permitting process.
