SITREP #: 3

SPILL #: 15309905601

TIME/DATE OF DISTRIBUTION: 4:00 p.m. March 3, 2015

POTENTIAL RESPONSIBLE PARTY (PRP): Colville, Inc.

INCIDENT LOCATION: Dalton Highway milepost 86, approximately 30 miles north of the Dalton Highway Yukon River crossing.

TIME/DATE OF SPILL: The incident occurred at 9:00 a.m. on February 25, 2015. Colville reported the spill to ADEC at 11:18 a.m. on the same day.

TYPE/AMOUNT OF PRODUCT SPILLED: The Colville tractor-trailer was transporting ultra-low sulfur diesel (ULSD). Colville estimates approximately 2,800 gallons of ULSD was released to the environment. Fuel transferred from the affected trailer was loaded into another trailer for transportation to Deadhorse. Upon arrival, recovered fuel was metered to determine the exact amount of product released.

CAUSE OF SPILL: Single vehicle truck accident, the cause of the accident is still under investigation. A hatch on the rear trailer compartment was breached after colliding with a 10-inch diameter spruce tree.

SOURCE CONTROL: The trailer was offloaded and retrieved from the ditch during the evening of February 25, 2015. Source control has been achieved.

RESPONSE ACTION: Colville has hired Emerald Services (Alaska), Inc. and ERM Alaska, Inc. to assist with the cleanup. ADEC responders completed delineating the spill site on February 26 and estimates the affected area to be approximately 0.07 acres. No pooled product was discovered during the delineation effort. Seven Emerald and one ERM personnel mobilized to the site on March 1. Upon arrival, the cleanup contractors established traffic control along the Dalton Highway while removing trees and unaffected snow from the delineated area to gain access to the contamination. On March 2, the cleanup contractors were able to gain access to the contaminated snow, vegetation and soil, and commence cleanup. As of today, approximately 700 cubic yards of affected snow, vegetation, and soil have been stockpiled on-site, awaiting transportation to Organic Incineration Technology’s (OIT) facility in Moose Creek, AK.
ADEC is monitoring the cleanup activities.

RESOURCES AFFECTED: The affected area consists of a boreal forest plant community, as well as black spruce
bog. No wildlife has been seen in the vicinity of the spill site, and no water ways or bodies have been affected,
to date.

FUTURE PLANS AND RECOMMENDATIONS: ADEC will continue to monitor the response.

WEATHER: Today: Snow likely; high 27°F; winds light and variable; chance of snow 70%; snow accumulation of
less than one inch. Tomorrow: Mainly cloudy with snow showers around in the morning; high 32°F; winds light
and variable; chance of snow 50%.
