1. Columbia River Lock Users Meeting Portland District Corps of Engineers August 14, 2007 US Army Corps of Engineers Portland District Portland District

2. Critical Infrastructure Ranking Model For the Columbia – Snake River Waterways Transportation System Laura Hicks, Chief Planning Branch August 14, 2007

3. Three Major Rehab Studies Underway Columbia/Snake System MCR Jetties 1,800 feet lost on North Jetty and 5,000 feet lost on South Jetty Lower Monumental Downstream lift gate John Day Horizontal cracking on monolith bases

4. 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

5. Budgeting Concerns  MVD ranking system’s main performance measures are commercial tonnage and outage time –metrics not very applicable to Columbia-Snake River System

6. Logic Diagram Columbia/Snake System

7.  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 Process Columbia/Snake System

8. 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 funding

9. NAVIGATION Columbia/Snake

14. The Dalles Navigation Lock Miter Gate Pintle Repair US Army Corps of Engineers Portland District Portland District Lance A. Helwig, P.E. Project Manager Pintle

15. 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)

16. 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)

17. What’s the overall plan? Phase/ActivityDateComments Temporary RepairsMar 07Done Install instruments + monitoring 29 Oct – 5 Nov 077d lock outage Interim RepairsMar 08Target repairs for scheduled 14d lock outage Visual inspectionSummer/Fall 087d lock outage, if necessary Design permanent repairs & new pintle assembly 2009Developing scope Final repairsFeb/Mar 2010Extended outage likely (30d) ($3M - $5M)

18. 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
