Cumberland River System - Operate and Maintain 10 Multi-Purpose Projects (4 Locks and 6 Dams)
Tennessee River System - Operate and Maintain 10 Locks (Partner with for Dams and Hydro)

Concern: Deteriorating Infrastructure
• 10 Dams preventing $750M annually in damages
• 2 largest reservoirs DSAC 1 (8 million acre-feet of storage)
• 18 Lock chambers at 14 sites
• 11 Locks in operation for over 50 years
• Average age of locks: 59 years
• Minimal advanced maintenance on projects (ARRA Helped)
• Currently “Fix projects as they Fail”
• Now moving towards “Fail to Fix” projects
Can we afford the infrastructure in our inventory?

• Currently longer tows must
perform double lockages
(increased time and money)
• New lock double the size
• New rail and road bridges
• Cofferdam complete
• Monolith walls under construction
Kentucky Lock
• $713.4M Project
• FY 11: $2.9M + $55M (ARRA)
• FY 12 Budget: $0M
• IWTF Funding Challenges

Overall Project – July 2011

BUILDING STRONG®
� Excavation and construction of 9 of 61 monoliths for new lock. Entire critical path of project for 2 years.
� Awarded Base contract (Jan 2010) and 5 of 10 options –
► $48.0M out of $57M total contract► 33 Month long contract (including 5 Opt’s)
� Remaining 5 options – Each option completes a monolith to full height
► $8.9M required to exercise all 5► Would increase contract length to 36 months or more
Upstream Monolith Contract

Lock Excavation - 6 Oct 2011
Slide 22
BUILDING STRONG®
Kentucky Lock Funding Status
� Project funding - 50% Federal & 50% Inland Waterways Trust Fund
(IWTF). IWTF - revenues from a special $0.20 per gallon Federal
tax on marine diesel fuel.
� American Recovery and Reinvestment Act (ARRA) - short term relief
for KY Lock & other navigation projects – not require IWTF match.
� KY Lock - $79.6M in ARRA funds - allowed new lock construction to
resume after its halt in 2006.
BUILDING STRONG®
KY Lock Future Funding
� Existing ARRA - Maintain construction activities thru 1st Quarter FY 13 (Upstream Lock Monoliths). To meet 2016 project completion date requires additional funds in FY 12
� Status of IWTF – Unlikely project receives significant additional funding until at least FY 13 - Depends on the “fix” to the IWTF by Congress
� No additional funding in FY 13 – Mothball project
