Air Quality Conformity Demonstrations

When COMPASS develops or updates the regional long-range transportation plan (Communities in Motion) or the Regional Transportation Improvement Program (TIP), it is required to demonstrate that the transportation projects funded via these plans will not degrade air quality in the Treasure Valley. This is referred to as an “air quality conformity demonstration.” Learn more.

The documents demonstrating conformity for Communities in Motion and recent TIPs are below. Find older conformity demonstration documents in the archives.
