We issued a $28,000 penalty to the landowner for this spill. Besides the penalty, and under state law, the owner also faces a Resource Damage Assessment for harm caused to public resources. In Washington, an oil spiller is responsible for adequately compensating the public for injuries to their resources. This may take the form of a restoration and enhancement project or study, or the spiller may be assessed damages, which are paid into a restoration fund managed by the state for such projects.
March 25, 2015, final update
Emergency response to the Sulphur Creek oil spill near Sunnyside has wound
down. Work is transitioning to Ecology’s Toxics Cleanup Program, which is
evaluating legacy contamination unrelated to the current spill of used oil from
an aboveground storage tank. The majority of the spill-related contamination has
been captured and cleaned up. Irrigation ditches and canals have been cleaned of
oil and debris and are in service for area farmers.
The remaining contamination on the former feedlot is being evaluated and future
cleanup and responsibility considered.
In a final report on oiled wildlife, FOCUS Wildlife Response and Consulting
says that 22 oiled wild mallards were captured, 6 died in care and 16 were
cleaned and released back to the wild. Early on, some 16 oiled mallards were
observed already dead in the wild. In addition, 57 oiled greylag domestic geese
were captured, one euthanized, and 56 were cleaned and made available for
adoption. All of the geese have been adopted.
March 16, 2015, 3 p.m.
FOCUS Wildlife Response and Consulting reports that seven of the 17 mallards
captured and cleaned of oil were released back to the wild today. The remaining
10 mallards are recuperating and should be released sometime later this week.
Some 19 domestic geese also oiled by the spill have been cleaned as of today and
the 38 remaining should be cleaned by the end of this week. FOCUS along with the
Washington Department of Fish and Wildlife are working to find homes for the
domestic breed geese as they cannot be released to the wild. The geese had been
living informally off the land when they were oiled. Calls to the wildlife
hotline has resulted in enough homes for all 57 geese that were captured and
will be rehabilitated.
March 13, 2015, 2 p.m.
The active search for oiled wildlife was suspended today. FOCUS Wildlife
continues to treat the birds collected in a rehabilitation center until they are
fit for release.
To date, 17 mallards have survived along with 50+ previously domesticated geese.
Nineteen birds were collected deceased or did not survive rehabilitation.
A flock of grey geese, previously domesticated, was gathered and is in the
stabilization stage of rehab. The first of the flock begin the washing process
Once the geese are rehabilitated they will need new homes, as they cannot be
re-released into the wilderness.
Anyone interested in adopting a small flock (5-10 at a time preferred) should
call 1-800-22BIRDS. Suitable adopters will need to meet specific requirements
and sign an agreement on how they will care for the birds.
NRCES crews installed a fence around the site of the leak today, and along with
Ecology, will continue to monitor the area throughout the weekend.
March 12, 2015, 3 p.m.
The unified command has suspended its onsite unit and further cleanup efforts
will continue using a virtual, unified-command
The National Response Corporation Environmental Services, (NRCES) remains on site as contracted and will place
a new plug in the tank; fence off the site; and other tasks before
demobilizing. NRCES will continue to check several areas of the site daily to
FOCUS Wildlife, the contractor working with the oiled birds, set up a
rehabilitation center in Pasco. Current relief efforts are focused on 22 live
mallards and approximately 50 domesticated geese. Nineteen deceased birds total
have been collected.
March 10, 2015, 2 p.m.
Response efforts continue with containment and clean up equipment deployed at
multiple locations. Crews continue to work to remove oil from the piping system
and in the ditches.
Good progress has been made and some containment equipment may be removed today
or in the near future.
Primary efforts continue to be focused near the spill site and the complex
system of ditches and pipes flowing to the Sulphur Creek Wasteway.
Wildlife assessment: Since March 10, the bird count
increased to approximately 20 live mallard ducks in custody, 18 deceased
mallards collected, and one domestic, non-native gray goose in custody. Several
other domestic, non-native gray geese are expected to be collected today.
The Department of Fish & Wildlife continues to monitor the established
hotline to report impacts to wildlife @ 1-800-22BIRDS (1-800-222-4737) or email
March 9, 2015, 9 a.m.
Nine oiled mallard ducks were captured and six deceased ducks were also
collected last week. Oiled birds are not cleaned immediately upon rescue; a rest
period must occur before the cleaning process starts.
A mobile wildlife rehabilitation system is on site and cleaning operations
are expected to begin this week. Efforts are still underway to confirm the spill
pathway. Investigation continues into the volume and cause of the spill.
Over the weekend, response efforts through the Unified Command focused on:
Cleaning up oil in the ditch near the spill site.
Continuing to collect and clean up oil at several locations including in at
the mouth of the Sulphur Creek Wasteway.
Monitoring for oil in the Yakima River and at the Fish hatchery on the Yakima
River in Prosser.
Surveying for oil birds and wildlife. Establishing the mobile rehabilitation
facilities and preparing to clean birds early next week.
Assessing oiled shoreline and determining the least impactful method to clean
Determining current costs and burn rate for the response.
Updating local officials, stakeholders and interested parties of the response
We continue to assess impacts to sensitive areas and determine where we can
collect and clean up oil.
March 4, 2015, 2 p.m.
Initial estimates are that 1,500 – 2,200 gallons of oil flowed into a ditch
leading to the Sulphur Creek Wasteway. The oil entered the Yakima River and
traveled downstream towards the City of Prosser. To date little oil has been has
been observed downstream of Prosser.
A Unified Command made up of Ecology, U.S. Environmental Protection Agency, the
Yakama Nation and the Responsible Party are continuing to direct response
The National Response Corporation (NRC), Yakama Nation, and Ecology Responders
continue clean-up efforts. A significant amount of absorbent pads, protective
boom and collection equipment has been deployed by Ecology and NRC responders at
multiple locations in the area to contain and clean up oil.
As of now the majority of the response is being paid for through Ecology’s Oil
Spill Response Account.
As reported yesterday, Ecology conducted one over-flight on Monday, March 2, and
several on the ground assessments to determine the impacts to shorelines,
sensitive areas and impacts to wildlife. The surveys confirmed:
The source is contained.
The ditch from the source to the Sulphur Creek Wasteway is heavily
The Sulphur Creek Wasteway is heavily oiled.
There are pockets of oil and sheening along the shores of the Yakima
River downstream to Prosser.
Minimal sheening downstream of the Prosser Diversion Dam.
Impacts to birds are verified. Ecology directed NRC to subcontract with Focus
Wildlife to begin addressing wildlife impacts.
Focus Wildlife is on-site today conducting surveys to locate impacted wildlife.
The Department of Fish and Wildlife has established a hotline to report impacts
to wildlife @ 1-800-22BIRDS (1-800-222-4737) or email
March 3, 2015, 2 p.m.
Responders have observed at least 50 birds that are moderately oiled as a result
of the spill.
Unified Command will work with a wildlife rehabilitation organization to conduct
surveys and a full evaluation of the impacts to waterfowl and other wildlife.
This will include any rehabilitation deemed necessary.
People are requested to stay away from oiled wildlife to minimize stress to the
animals. Citizens should not attempt to capture any oiled wildlife; such efforts
could endanger the safety both of the public and the animals.
An over-flight taken by Ecology the afternoon of Monday, March 2, showed the
vast majority of the oil released remains in a 7-mile stretch of Sulphur Creek,
which is boomed at the confluence with the Yakima River.
A light sheen of oil can be seen for approximately 12 River Miles along the
Yakima River between Sulphur Creek and Prosser, with little observed below the
Ecology has established a Unified Command with representatives from the Yakama
Nation, the US Environmental Protection Agency, and Deaton Land LLC, owners of
the property where the release occurred.
On Tuesday, oil collection and shoreline assessments will continue along Sulphur
Creek and on the Yakima River.
March 2, 2015 3 p.m.
Washington Department of Fish and Wildlife (WDFW) has activated its oiled
wildlife hotline where citizens may report birds or animals affected by the
spill. The Yakima River provides habitat for hundreds of fish and wildlife.
Sulphur Creek drains into to the Yakima River near the Sunnyside Wildlife Area,
where waterfowl are wintering. The area also is home to river otters, muskrats,
beaver and other water-oriented mammals
Oiled Wildlife Reporting Hotline:
The public may notify the Wildlife Branch of oiled wildlife observations by
leaving a detailed message at 1-800-22BIRDS (1-800-222-4737) or email
Please describe how many animals were observed, the location of the animals
observed, how much oil was observed on the animal, and whether or not the animal
appeared mobile or incapacitated. Reports received from the public will be
routed to personnel in charge of searching for and recovering oiled wildlife.
Members of the public are requested to stay away from oiled wildlife to minimize
stress to the animals. They should not attempt to capture any oiled wildlife; as
such efforts could endanger the safety both of the public and the animals.
Volunteer Information: We are not requesting volunteer assistance at this time. In the event that volunteers are needed, a separate Public Service
Announcement will be issued instructing the public on available opportunities.
