Oregon InternationalPort of Coos BayWRDA Section 203 Process:Channel Modification Project• Investigate potential navigation improvements under WaterResources Development Act of 1986 (Section 203)• U.S. Army Corps of Engineers (Corps) is the lead agency• Authorizes non-Federal interest to undertake their ownfeasibility study of proposed navigation improvements• Studies must comply with Corps guidance• ASA makes a recommendation to Congress

Oregon InternationalPort of Coos BayWhy Section 203 Process?• Potential for Federal cost sharing of channel modificationconstruction• Maintain Federal navigation channel status (O&M costscovered or cost shared by the Federal government)• Permitting process somewhat streamlined

Oregon InternationalPort of Coos BayStudy Phases• Phase 1: Preliminary Studies (2007–2008)• Phase 2a: Alternative Formulation & Detailed TechnicalStudies (2009-2011)• Phase 2b: Draft FS & EIS (2012-2013)• Phase 3: Final FS & EIS (2013-2014)

Oregon InternationalPort of Coos BayPhase 1: Preliminary Studies (2007-2008)• Fatal Flaw Analysis– Economic (Benefit/Cost)– Environmental (Henderson Marsh Mitigation)– Engineering (Dredge Disposal, Preliminary Costs)• Wetland Delineation of Henderson Marsh• Preliminary Mitigation Plan for Henderson Marsh• Public Scoping for FS/EIS

Oregon InternationalPort of Coos BayPhase 2a: Alternative Formulation &Detailed Studies (2009-2011)• Preliminary Screening of Possible Commodities and TerminalLocations• Selected Configurations to Study in Detail (AlternativeFormulation)• Detailed Technical Studies– Engineering– Economics– Environmental

Oregon InternationalPort of Coos BayPhase 2a: Preliminary Screening Results• Expansion or development of terminals downstream of RM 9• Full range of commodities examined• Alternative Formulation– No deepening, 400’ wide channel– 45’ deep, 400’ wide channel– 49’deep, 450’ wide channel• Henderson Marsh used for dredge disposal, so site can bedeveloped as a terminal (49’ deep, 450’ wide)
