5-Year Maintenance Planning for Non-Routine Navigation Laura Hicks, Margie McGill, and Robert Leach initiated effort: –Integrate/present unconstrained budget needs for Snake & Columbia River infrastructure –Speeds and improves funding for system- wide maintenance efforts…Northwestern Division and HQUSACE using information to pursue funding –Successfully targeted specific projects, e.g. Channel Deepening and LoMo rehab

Questions

Major Rehabilitation Projects (e.g. Lower Monumental) Engineer Pamphlet Economically justified by benefit-cost analysis;* Work (construction) will extend over at least two full construction seasons; Fully funded cost estimate exceeds $10.6 million (FY 06) * Local ratio is typically <3; means region competes poorly vs. other national efforts. Therefore, funding likely only if President’s proposed fund location remains in Operations & Maintenance (O&M) account (vs. Congressional preference for funds to be in Construction General (CG) account).

Major Maintenance Reports (may or may not lead to major rehabilitation projects) Approx. Overall Project Cost Estimates > $40-$50 million McNary and Lower Granite Report > 2007 (final) Total Cost (both projects) = $23.5 million Ice Harbor Draft Report > TBD Little Goose Draft Report > TBD LoMo Start Plans and Specifications > FY 09 LoMo Fabrication (if necessary) > FY 10 LoMo Preliminary Lock Outage > Dec 2010 – Mar 2011

Columbia/Snake River Navigation System Capabilities (Walla Walla & Portland Districts )

Maintenance Categories Decision Diagram

Maintenance Categories Urgent and Compelling. Must have an inefficient safety rating, as well as a poor reliability rating possessing a potential to close the navigation lock. The reliability rating is based on a five-year forecast ( ) for the component. Critical. Typically, components in this category have a moderate safety rating or a poor reliability rating with potential to close the navigation lock. The reliability rating is based on a five-year forecast ( ) for the component. Moderate. Components in this category require repair but their current state does not pose a safety issue or a reliability issue. These components have large outage requirements (>=4 weeks). Therefore, repairs become a higher priority if the Columbia/Snake River navigation system has a planned extended outage. Minor. Components in this category require a low priority repair to improve maintenance or operability.
