(3) Consider the concerns of Federal land management agencies that have jurisdiction over land within the boundaries of the State;

(4) Cooperate with affected local elected and appointed officials with responsibilities for transportation, or, if applicable, through RTPOs described in section 450.210(d) in nonmetropolitan areas;

(5) Consider the concerns of Indian Tribal governments that have jurisdiction over land within the boundaries of the State;

(6) Consider related planning activities being conducted outside of metropolitan planning areas and between States; and

(c) Two or more States may enter into agreements or compacts, not in conflict with any law of the United States, for cooperative efforts and mutual assistance in support of activities under this subpart related to interstate areas and localities in the States and establishing authorities the States consider desirable for making the agreements and compacts effective. The right to alter, amend, or repeal interstate compacts entered into under this part is expressly reserved.

(f) For non-NHS highways, States may apply principles and techniques consistent with other asset management plans to the transportation planning and programming processes, as appropriate.

(g) The statewide transportation planning process shall (to the maximum extent practicable) be consistent with the development of applicable regional intelligent transportation systems (ITS) architectures, as defined in 23 CFR part 940.
