What is the planning requirement for a river designated by the Secretary of the Interior (under Section 2(a)(ii) of the Wild & Scenic Rivers Act)?

The requirement for a comprehensive river management plan (CRMP), does not apply to state-administered, federally designated rivers. Federal land managers are responsible for protecting river values in all agency planning and management actions for any portion of a 2(a)(ii) river that flows on federal lands. In some cases, the petitioning state has a requirement for a plan. The existence of a state or local plan to protect river values is one of the factors considered by the National Park Service in its review of the 2(a)(ii) nomination for the Secretary.
