170.414—How is the tribal long-range transportation plan used and updated?

The tribal government uses its IRR long-range transportation plan in its development of a tribal priority list or TTIP. To be consistent with State and MPO planning practices, the tribe or BIA (for direct service tribes) should:
(a) Review the IRR long-range transportation plan annually; and
(b) Update the plan every 5 years.
