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

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
