Cleanup Continues; Focus
On Submerged Oil
July 2010 Enbridge Oil Spill
Marshall, Michigan	August 2011
During the Spring of 2011, EPA directed the responsible party, Enbridge
Energy LP, to reassess Talmadge Creek and the Kalamazoo River bottom
and adjoining overbank areas. Under the direction of the U.S.
Environmental Protection Agency, cleanup workers placed physical
barriers at strategic locations in these waterways to contain oil that
resurfaced as a result of wanner weather.
Assessing Submerged Oil
The Spring re-assessment revealed the presence of substantial pockets of
submerged oil. More than 220 areas of moderate-to-heavy contamination,
covering around 200 acres of river bottom, requires cleanup. The
inspection also identified a small number of overbank locations and more
than 300 solidified oil deposits needing cleanup.
Recovering submerged oil
Responders are using a number of techniques to recover submerged oil
from the sediment. These methods are designed to recover submerged oil
in a minimally invasive way.
Sediment agitation frees submerged oil so it can be collected, removed and sent off-
site for disposal.

Assessment creivs locate and estimate the extent of submerged
oil.
Reopening the Kalamazoo River
EPA and MDEQ are working closely with local and
state health departments and Enbridge to detennine
when the Kalamazoo River can be reopened.
Submerged oil recovery should be completed in
September. At that time, the agencies will determine
whether any additional work is needed. Potential public
safety risks from cleanup crews, boats and vehicles
working along the river will be considered to detennine
whether a portion of the nver can reopen this year.
Recovering oil from overbanks
After receiving permit approvals from the MDEQ, and
under EPA direction, Enbridge resumed excavating oil-
contaminated soil in overbank areas along the
Kalamazoo River. This will greatly reduce the amount
of oil sheen entering the river during rain or flooding.
Solidified oil removal
Weathering turns oil into a tar-like solid. Last spring,
responders identified small areas of weathered oil on
overbank areas. Current soil recovery operations
include removal of these tarry substances using gentle
techniques to minimize damage to the surrounding
environment.
Air monitoring and sampling
EPA directed Enbridge to increase air monitoring in
work areas and nearby communities to protect
residential areas from potential air pollution released by
the cleanup work.
Odors may be present as work proceeds, especially in
the Ceresco, Battle Creek and Morrow Lake areas.
Monitoring and sampling will be focused in areas
where odors can be detected.
By the numbers (as of August 12, 2011)
Oil/water mixture recovered:
15.3 million gallons
Oil recovered and recycled:
766,000 gallons
Soil/debris disposed of off-site:
127,000 cubic yards
Personnel on site
860
Costs to date
$31.3 million
Temporary roads and platforms are constructed so heavy
equipment can be brought in to excavate oil-contaminated soil
along the Kalamazoo River.
