Date of incident: July 25, 2010
Location: Marshall, MI, on a tributary to the Kalamazoo River
Case status: Cleanup work continues. Trustees have conducted preassessment work for Natural Resource Damage Assessment and have issued a Notice of Intent to proceed with restoration planning.
Overview: On July 25, 2010, a failure occurred
in a 30-inch diameter pipeline releasing diluted bitumen, a heavy form of crude oil, into a tributary creek of the Kalamazoo River in
Marshall, MI. This type of oil is also referred to as "tar sands oil." Enbridge, the owner and operator of the pipeline, estimated that approximately 843,000 gallons spilled. Oil traveled approximately 40 miles downstream in the Kalamazoo
River. Containment and absorbent booms were placed and the oil did
not pass Morrow Lake, located about 10 miles east of Kalamazoo, MI. NOAA
provided trajectory support to Coast Guard Sector Lake Michigan to predict
transport of oil in the Kalamazoo River. NOAA and partner agencies also
provided recommendations to EPA on ways to minimize the impact of the cleanup
activities by identifying ecologically sensitive areas and providing
information on cleanup techniques.
NOAA is coordinating with co-trustees and Enbridge, to collect information as part of the Natural
Resource Damage Assessment (NRDA) . The purpose of NRDA is to determine
the appropriate type and amount of restoration needed to compensate the public
for injuries to or lost use of their natural resources from the oil spill and
associated response activities.
