    • Background•Failure of approximately 5 feetof 30” steel pipe•On July 26th Enbridge’s Line 6Breleased approximately 843,000gallons of Canadian crude oil;approximately 337,0000 gallonsreached Talmadge Creek andthe Kalamazoo River•Both watercourses were atflood stage at the time of theincident, pushing oil into thecontiguous floodplains andwetlands

    • Design Concepts•Created representativecross sections•Calculated shear stressesthroughout stream (0.7-1.5lbs/sf) at flood stage•Assess and match soils•Assess plant communitiesand create appropriatenative seed mixes•Considered marketavailability of materials,construction sequencing,and ability to rapidly install
    • Design Concept•Coir logs•Backfill•Seed•NAG C-125BN•Have surveyors stake pre-remediation bankfull mark basedon original survey
