Study Final Recommendation
? The Evaluation Team and the PRB acknowledged
the potential cost savings of 25M was very
speculative, due to the preliminary nature of the
VE design. ? The PRB concluded that the risks
associated with the long term operability,
maintainability, and navigation safety of the VE
to be unacceptable, regardless of the potential
cost savings.

Lower Monongahela River Project Impacts of
Constrained Funding

• Completion of Charleroi Locks is delayed 6 years
• Risk of failure at L/D 3 increases significantly
  major rehabilitation may be required to extend
  project life until 2016 when Dam 3 is removed.
• Increased OM costs to maintain depreciated lock
  operating equipment at Locks 3 4
• Total benefits foregone with FY-05 constrained
  schedule are estimated at 1.2 billion.

Requirements

• Locks 3 4 (Normal Maintenance Schedule)
• 2007 Repair Valves Gate Miter Sills
  2.0 M
• 2010 Lock Gate Replacement or Rehab
  1.5 M
• 2017 Repair Valves Gate Miter Sills
  2.2 M
• Total (Each Project) 5.7 M
• Dam 3
• Significant potential for foundation failure
  without major Rehabilitation. Pool 3 could be
  lost, resulting in significant impacts to Locks 4
  stability, Municipal water intakes, and private
  facilities.
