Our Navigation System
Uniqueness of the system and national metrics
OMBill Metric of $/tons Multipurpose projects Number 1 national export system for
grain System reliability is critical to users Transportation of juvenile salmon
Budgeting Concerns
MVD ranking system’s main performance measures are commercial tonnage and outage time –metrics not very applicable to Columbia-Snake River System
Logic DiagramColumbia/Snake System
Four broad ranking categories relate roughly to 4 FY08 funding increments and similar to other river system approach
Decision points evolved from discussions with the Operating Projects as well as internal team discussions
Safety and Reliability were determined to be the most critical when evaluating a budget item
Some adverse results not immediate (i.e., eventual dredging shutdowns to due loss of disposal site because of environmental non-compliance)
Found need to add ‘Essential Information Requirement’ to address items considered critical but ranked lower than critical in original diagram – MCR jetty monitoring, Dam Safety monitoring, hydrographic condition surveys all moved to ‘Urgent & Compelling’ based on results of applying updated logic diagram
Logic Diagram ProcessColumbia/Snake System
Columbia/Snake System Results
FY08 rankings compared to FY09 logic diagram results Mostly consistent Rehab reports ranked higher Some (mostly smaller $) maintenance items
ranked lower
Urgent and Compelling Fairly Consistent with EC guidance for level 1

Pintle
What’s the problem?
March 07 lock outage (14 d) Cracks in both miter gates near
pintle, north gate worse Lower 30’ not mitering Undesirable load path Performed temporary weld
repairs
May 07 – current Vibrations & shock loading Monitoring situation (visual) Did cracks reopen?
Propagated? Did bolts shear off again (2005)? Lower Granite (NWW)
What needs to be done now?
Visual inspection of pintle area (diving/submersible won’t work)
Install instruments, strain gages & accelerometers
Lock outage 25 Oct (12 hr), sweep sills 29 Oct – 5 Nov (7d)
Objectives Possible minor repairs Collect data for interim repair in Mar 08 Ensure gate safe for continued use Develop contingency plans (as appropriate)
What’s the overall plan?
Phase/Activity Date Comments
Temporary Repairs Mar 07 Done
Install instruments + monitoring
29 Oct – 5 Nov 07 7d lock outage
Interim Repairs Mar 08 Target repairs for scheduled 14d lock outage
Visual inspection Summer/Fall 08 7d lock outage, if necessary
Design permanent repairs & new pintle assembly
2009 Developing scope
Final repairs Feb/Mar 2010 Extended outage likely (30d) ($3M - $5M)
On-going Challenges
Currently blind (underwater), need instruments Funding: new problem, not part of 08 budget Unscheduled outages impacts to river users Commo Plan, need to work w/ industry &
stakeholders (periodic updates) Upstream lock gate
Vibrating Investigating problem

TDA Spillwall ExtensionUpdate
Mar 07: invited river users to ERDC Reps from Shaver, Tidewater and Foss Bay 6/7 wall – no navigation impacts
Jul 07: wall moved to Bay 8/9 reduced gas Sep/Oct 07: model 8/9 wall
ERDC (H. Parks) run model tug Expects no impacts to navigation Corps will send out model results to river users Determine if river user trip is necessary
