This document discusses wetland and stream restoration techniques used following an oil spill from Enbridge's Line 6B pipeline into Talmadge Creek and the Kalamazoo River in Marshall, Michigan in July 2010. Design concepts included creating representative cross sections, assessing shear stresses and plant communities, and using coir logs, backfill, seed mixes, and other materials. Implementation involved restoring creek banks and installing structures like rock chutes, ramps, and wildlife habitat features. Post-restoration monitoring showed regrowth of vegetation and stabilization of restored areas over time. Unique techniques addressed heavy groundwater flows and unconsolidated soils.

2. Background
•Failure of approximately 5 feet
of 30” steel pipe
•On July 26th Enbridge’s Line 6B
released approximately 843,000
gallons of Canadian crude oil;
approximately 337,0000 gallons
reached Talmadge Creek and
the Kalamazoo River
•Both watercourses were at
flood stage at the time of the
incident, pushing oil into the
contiguous floodplains and
wetlands
11. Design Concepts
•Created representative
cross sections
•Calculated shear stresses
throughout stream (0.7-1.5
lbs/sf) at flood stage
•Assess and match soils
•Assess plant communities
and create appropriate
native seed mixes
•Considered market
availability of materials,
construction sequencing,
and ability to rapidly install
