Latest EPA update on Yellowstone River oil spill

Billings, Mont – July 15, 2011 – The U.S.
Environmental Protection Agency (EPA) continues to oversee the
response to the ExxonMobil spill on the Yellowstone River. This
weekend, EPA will provide direction and oversight as Exxon removes
any residual oil from two segments of pipeline on either side of
the break location. EPA and the state have reviewed and approved
procedures to ensure that there are no further releases of oil into
the environment as a result of these activities.

There are 750 personnel on site with 540 currently in the field
engaged in cleanup or sampling activities. Cleanup crews have used
over 50,000 feet of absorbent booms and 260,000 absorbent pads,
among other materials. There are 56 boats on scene as well.

At approximately 11:00 PM on Friday, July 1 a break occurred in
a 12-inch pipeline owned by ExxonMobil that resulted in a spill of
crude oil into the Yellowstone River approximately 20 miles
upstream of Billings, Montana. The current estimate of the amount
of oil released remains at 1,000 barrels based on information
provided by ExxonMobil. EPA’s primary concern is protecting
people’s health and the environment. EPA will remain on-site to
ensure cleanup and restoration efforts do just that. EPA continues
to hold ExxonMobil, the responsible party, accountable for
assessment and cleanup.
