While the oil and train cars have been removed, worked continues at the site
in Mosier, OR to clean up the area.
Currently crews are testing and sampling the earth and groundwater
potentially impacted by the oil train derailment.
A group made up of NOAA, Oregon Dept. of Environmental Quality (DEQ), tribes,
and cities is working together to ensure appropriate surface water monitoring.
The nearby park reopened but city and state officials will continue to work
on a restoration plan for the fire damaged area, construction and excavation
Future questions regarding the status of the site should be directed to DEQ

Crews in Mosier transported the last of the derailed cars to a steel
recycler in Portland, transitioning the incident from emergency operations to a
Union Pacific and its contractors will continue to assess and remove any
contaminated soil and replace it with clean-fill material. Crews will also
repair all damage to the Mosier wastewater treatment plant.
The remaining cleanup and environmental monitoring work will be overseen by the
Oregon Department of Environmental Quality, with support from the Environmental
Protection Agency and other local, state and federal partners.

All of the oil has been removed from the rail cars and transported to The
The remaining rail cars are being cleaned and decontaminated, and are being
trucked to Portland for recycling.
Once all the rail cars have been removed, crews will begin removing
June 7, 12:30 p.m.
Overnight crews recovered a significant amount of oil from derailed train
cars and could have all of the oil transloaded offsite by the end of today.
Once all of the oil is removed from the site crews will begin cleaning and
removing the damaged rail cars.
The oil is being transferred to The Dalles on special tanker trucks and
staged for transport by rail to Tacoma, Wash., its original destination.
Water-sample tests showed that the water is safe to drink. Monday, June 6,
the city lifted the boil water advisory for all residents
except for two homes on Rock Creek Road.
Union Pacific has identified a preliminary cause of the crash, stating a bolt
that fastens the rail to the railroad ties may have been at fault. The final
determination of the cause has not been made.
Booms remain in place for precautionary measures but no new signs of oil
sheen have been seen or reported on the river or other waterways.
Environmental specialists believe the source of the sheen has been controlled.
Crews continue to carefully monitor air and water quality around the site.
A temporary bypass system, which allowed the city to restore sewer service to
local customers, remains in place. The city’s wastewater is being
collected and trucked to Hood River for disposal.
Federal, state, tribal, and local authorities remain at the command center
near the scene to coordinate response until the cleanup is complete.
June 6, 2 p.m.
Response crews made significant progress on environmental cleanup and oil
removal from the train cars that derailed in Mosier.
Interstate 84 and the Mosier exit 69 have been re-opened.
The 96-car train was carrying Bakken crude oil and 16 cars derailed on
Friday, June 3. Officials estimate that 42,000 gallons of crude escaped from
four rail cars.
Recovery of oil includes 10,000 gallons from the wastewater system, and the
remaining 32,000 gallons were either burned off and vaporized, captured by booms
in the Columbia River, or absorbed by soil, with an undetermined amount
remaining in wastewater lines.
Thirteen cars remain at the incident site, two have been fully pumped, and the
remaining 11 are in the process of having oil transferred to tanker trucks and
transported to The Dalles. The oil will be staged in The Dalles until resuming
its trip to Tacoma, Wash.
Most essential services have been restored to Mosier. A short-term fix has
allowed operations to continue on the city’s wastewater treatment plant, which
is now operating and allowed the evacuation to be lifted.
The City of Mosier continues to ask residents to conserve water. As a
precaution, the boil water order remains in effect. Bottled water is available
to anyone who needs it at the Union Pacific Claims Center across from the Mosier

Much work was completed Sunday and after setting up a bypass for the waste
management system, evacuated residents were allowed to return to their homes.
Sampling is being conducted on the drinking water and residents are being
asked to boil water until the sampling results are complete.
Air monitoring continues to be conducted 24/7 and is currently in the
Status of rail cars
All oil has been removed from the damaged rail cars. Oil from the cars is
being vacuumed out onto special tanker trucks and being transferred to The
Dalles before going to is final destination in Tacoma.
Thirteen rail cars remain on site, two have been fully pumped, on partially,
the remaining 10 will be pumped as quickly as possible.
Additionally, the damaged rail was repaired.
Status of environmental damage
An unrecoverable sheen was observed in the water Sunday (no new spills) and
all protective boom will remain in place.
Contaminated soil has been removed and today begins planning for the long term
soil remediation. Ten - 15 acres of wildland burned and was contained quickly
within the first 24 hours after the derailment.

Overnight crews were able to make good progress and this morning 13 cars
The priority today is focusing on the community and returning residents to
their normal daily lives. The waste-water system was damaged in the derailment
and residents have not been able to put anything down the drain.
Crews are working to restore the system and remove all oil from the site so
those evacuated from their homes can return.

Ecology is responding to a train derailment in
Mosier, Oregon. Ecology responders are en route with
equipment and expectation that oil will enter the
Columbia River and possibly impact Washington
We launched an overflight from Olympia to
determine if oil is entering the Columbia River and
also activated our crisis management team to support
our responders in the field and provide support to
the response in Oregon if needed.
Confirmed information includes:
- Up to eight rail cars have derailed with
some on fire close to the Town of Mosier, Oregon
- The derailment is also adjacent to a creek
that flows into the Columbia River
- I-84 is closed
- One elementary school has been evacuated
- Wildfire crews have been dispatched
- Oil spill response contractors have been
dispatched Smoke has been reported in the area
Local fire authorities and other responders will be
monitoring for air quality.
Inhalation of smoke and vapors may cause headaches,
dizziness, nausea, vomiting, irritation of the eyes
and throat and difficulty breathing at high levels
of exposure, particularly in people with asthma or
other respiratory illnesses.
People in the affected area should avoid smoke if
the see or smell it.
This is an evolving event and we will share
additional information as we receive it.
