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

Slide 19

BUILDING STRONG®

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
