Tribal Designations Workgroup

The NTAA/EPA Tribal Designations Workgroup is now inactive.

In the past, the Tribal Designations Workgroup provided an opportunity for Tribal air quality professionals to interact directly with EPA officials about previous EPA NAAQS Designations. The National Designation & Implementation Work Group (2001 - 2003) took a close look at the potential impacts to Tribes from the NAAQS Designations process, starting with Ozone.
