The Denali Fuel Company site is located at 8123 Hartzell Road in the Shady Acres Subdivision, Anchorage, Alaska. The property is in a commercial/industrial area at the east end of Dimond Boulevard and includes approximately 100 feet of frontage on Hartzell Road near East 84th Court. The site is currently leased and is used to store building materials. A 12,000-gallon diesel UST and dispensing system was installed on-site in 1986. The site operated as an unmanned, key-card fueling facility for commercial vehicles until its closure and removal in September 1991.
A site assessment was performed in conjunction with the UST removal activities. Diesel fuel contaminated soil and groundwater, above DEC cleanup levels, were identified around the UST to the full extent of the excavation. Additional contaminated soil was excavated in October 1991. Approximately 300 tons (total) of diesel contaminated soils were transported off-site and thermally remediated. A limited release investigation was performed in September 1995. Three soil borings were advanced, sampled for laboratory analysis and completed as monitoring wells. Corrective action (cleanup) activities were initiated in November 2000.
A total of 1,490 tons of petroleum contaminated soil was transported off-site for storage and thermal remediation. Two additional groundwater monitoring wells were installed in September 2001, to further delineate the extent of groundwater contamination. In August 2002, five additional soil borings and one private water well were sampled. The submitted report documented high levels of shallow soil contamination remain at the site. The facility continues to receive grants through the State of Alaska Financial Assistance Program to fund cleanup activities.
Public Health and Environmental Concerns
The contaminants of concern (COCs) are primarily petroleum; diesel and diesel components (BTEX). Petroleum contaminated soil remains on property. Extensive impacts to the groundwater have been identified both on and off property. Shallow and deeper drinking water wells are present in the area, however, no contamination of drinking water wells has been documented. The extent of any confining aquiclude in the area has not been defined.
The results of the 2002 investigation activities have been reviewed by DEC. Excavation of the shallow soil contamination is planned for 2003. Groundwater monitoring is currently in place and will continue.
