To amend the Aamodt Litigation Settlement Act to modify a provision relating to the extension of certain dates for the completion of the Regional Water System, and for other purposes.

HR 6869 amends the Aamodt Litigation Settlement Act to change how deadlines for completing the Regional Water System can be extended. It requires that all involved parties - the Pueblos, the U.S. (via the Secretary), the State, the City, and the County - must agree that an extension is "reasonably necessary" before deadlines can be modified. This replaces the previous automatic extension process with a new agreement-based mechanism. The bill directly affects the Regional Water System project and the entities responsible for its completion. The change aims to clarify the conditions under which project deadlines may be extended.
