National Tribal Air Association

The NTAA/EPA Tribal Designations Workgroup provide an opportunity for Tribal air quality professionals to interact directly with EPA officials about upcoming EPA NAAQS Designations. Recently re-formed, and building on the earlier work done by The National Designation & Implementation Work Group (2001 - 2003), this Workgroup will be taking a close look at the potential impacts to Tribes from the NAAQS Designations process, starting with Ozone.

These calls are generally held on the 1st Thursday of each month at 2pm Mountain, 1pm Central, 12pm Mountain, 11am Pacific, 10am Alaska.
