Yellowstone River Cleanup and Recovery Update

ExxonMobil Pipeline Company provided the following update as Unified
Command cleanup operations continued Friday following a release of oil
into the Yellowstone River on July 1.

CLEANUP STATUS

Under the direction of the Unified Command, more than 500 people are now
involved in the response and cleanup effort including ExxonMobil′s North
America Regional Response Team, the Clean Harbors and ER oil spill
response organizations and additional contractors. Almost 400 people are
along the river banks today to clean up oil.

We have deployed more than 9,000 feet of boom and almost 160,000
absorbent pads to clean up oil adjacent to the river. Deployment will
continue to focus on the highest priority areas to reduce environmental
impact. Twenty boats are available for deployment on the river when
conditions permit.

The EPA is leading the Unified Command Center cleanup activities and
conducting ongoing air and water quality monitoring. Ongoing air quality
monitoring has confirmed there is no danger to public health. Municipal
water systems continue to be monitored by the EPA; no reports of impacts
have been received to date. For additional information, please visit www.epa.gov/yellowstoneriverspill.

COMMUNITY OUTREACH AND CLAIMS UPDATE

Direct contact with those impacted by the spill continues. To date we
have received 263 calls from the community. Our team is responding to
approximately 85 claims related to property, agriculture and health.
More than one hundred calls have been from people offering volunteer
assistance. We appreciate the support of the Billings community as we
work to restore the area.

Our commitment is to make every effort to respond to the concerns of
each individual within 24 hours. Additionally, we are increasing our
on-the-ground response team to work directly with people who have been
affected.

To address individual health concerns, teams of trained environmental
specialists are conducting air and water quality testing. Those who may
have been affected are encouraged to use the community information line
(1-888-382-0043).

WILDLIFE ASSESSMENT AND RECOVERY

We continue to work with International Bird Rescue, U.S. Fish and
Wildlife Service and Montana Fish, Wildlife and Parks to survey the area
for impacts to wildlife. Members of the team are surveying the affected
areas of the river for oiled wildlife. We are also inspecting the
property of landowners who have called the claims and wildlife hotlines.

On Thursday, International Bird Rescue collected a toad on a landowner′s
property. The toad was cleaned on site and released, bringing the total
number of treated wildlife to two. A garter snake was treated and
released on Wednesday.

In addition, several lightly oiled birds were observed, none required
capture or cleaning. U.S. Fish and Wildlife Service will be performing
aerial flights specifically looking for birds in impacted areas.

Today, two boats are scheduled to go out onto the slack, or shallow,
water to continue to search for any additional wildlife that may have
been affected by the incident.
