  1. 1. Wetland and Stream Restoration Techniques Following EmergencyWetland and Stream RestorationResponse Actions to the Line 6B Oil Leak in TechniquesMichigan Marshall, FollowingEmergency Response Actions tothe Line 6B Oil Leak in Marshall, Michigan Ecological Consulting Native Plant Nursery Restoration Services Cultural Resource Management
  2. 2. 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

  11. 11. 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
  12. 12. Design Concept•Coir logs•Backfill•Seed•NAG C-125BN•Have surveyors stake pre-remediation bankfull mark basedon original survey
