(i.e., "Budget EC"). In determining whether project work falls within
the dollar thresholds set forth in paragraphs 11-3.a(2) and 11-3.b
above, the dollar value of work on separate projects shall not be
aggregated, even if within the same river or waterway system.
11-4. Correction of Design or Construction Deficiencies.
Occasionally a project may require modification after project
completion because of a deficiency detected in the original Federal
engineering design or construction of the project. A design or
construction deficiency is a flaw in the Federal project that
interferes significantly with the project's authorized purposes or
full usefulness as intended by Congress at the time of initial
construction. A design deficiency may be patent and readily
observable or latent and remain hidden for years after completion of
the project. Work required to correct a design or construction
deficiency can be accomplished under existing project authority
without further congressional authorization if the proposed corrective
action meets all the following criteria: (ER 1165-2-119)
a. It is required to make the project function as initially
intended by the designer in a safe, viable and reliable manner.
b.
It is not required because of changed conditions.
c. It does not change the authorized scope, function, or
purpose of the project.
d. It is incrementally justified by current economic
considerations or otherwise needed and justified for safety reasons.
e.
It is not required because of inadequate local maintenance.
f. If corrective measures are proposed and adopted that
involve cost sharing, there is a non-Federal sponsor willing to enter
into a project cost sharing agreement to cover the cost sharing
requirements (using the same percentage as specified in WRDA 1986 for
the project purpose(s)).
11-5. Dam Operations Management. Corps of Engineers dams are managed
in accordance with the safest and most effective criteria and
procedures that can practicably be established. Projects are
inspected at appropriate intervals for signs of weakness or distress
by trained personnel. A Dam Safety Plan is prepared for each dam
consisting of: an emergency notification procedure; a description or
list of conditions leading to emergency situations and way of dealing
with them; reservoir de-watering procedure; dam failure inundation
maps; a listing of location, types, and quantity of emergency repair
materials and equipment; details outlining responsibilities for
inspection and execution of emergency repairs; and a list of
contractors available within a reasonable distance of the dam. (ER
1130-2-530)
11-6. Dam Safety Assurance. This program provides for modification
of completed Corps dam projects when detailed studies indicate that
safety improvements are warranted in light of present day engineering
standards and knowledge. The program facilitates upgrading of dams
and related facilities constructed or operated by the Corps when new
hydrologic or seismic data or changes in state-of-the-art design or
construction criteria make upgrading necessary for safety purposes.
The indicated modifications must be within the Chief of Engineers
discretionary authority to rectify, or a specific congressional
