Summary

The Secretary of the Army, using the Chief of Engineers, must start and run a national program to inspect dams as soon as possible to protect people and property. All U.S. dams must be inspected except four kinds: those managed by the Bureau of Reclamation, the Tennessee Valley Authority, or the International Boundary and Water Commission; dams built under licenses from the Federal Power Act; dams a State agency inspected in the 12 months before August 8, 1972, if the State’s Governor asks to exclude them; and dams the Secretary decides pose no threat. The Secretary may inspect Federal Power Act–licensed dams if the Federal Energy Regulatory Commission asks, and may inspect IBWC dams if that Commission asks. If a State dam safety agency asks about a dam whose failure could affect the State, the head of any federal agency must either give the State information on the dam’s design, operation, upkeep, condition, or emergency plans, or let a State official take part in the federal inspection.
