Description

 

The Sunny's Chevron site is located at 152 East Pioneer Avenue, on the northeast corner of Pioneer Avenue and Shelford Street, Homer, Alaska. The property is situated in a commercial/light industrial zone. The site is currently operating as an auto repair business. Three USTs were installed in 1978, and consisted of one 4,000-gallon gasoline tank, one 3,000-gallon gasoline tank and one 2,000-gallon gasoline tank.

 


Public Health and Environmental Concerns

 

The contaminants of concern (COCs) are primarily petroleum; gasoline and gasoline components (BTEX). Petroleum contaminated soil was excavated and thermally remediated. Impacts to on-site groundwater have been identified. Off-site contaminant migration via utility conduit trenches is a concern and is still being investigated and evaluated.

 


Response Actions

 

In July 1989, the 4,000-gallon tank was taken out of service. A limited site assessment/characterization was performed in January 1990. Eight soil borings were advanced. Two of the five soil samples and both water samples collected contained contamination above the cleanup levels. The site operated as a retail gasoline station utilizing the 2,000-gallon and 3,000-gallon tanks until September 1995, when these two tanks were also taken out of service.


In May 1996, a limited release investigation was conducted. Fifteen test pits were dug. Field sampling activities indicated a contaminant plume that extended south-southwest from the fuel dispenser island. In June 1998, all three tanks, associated piping, pumps and dispenser island were removed. Contaminated soils were excavated and stockpiled on site. In June 2002, corrective actions were undertaken. Approximately 1,400 cubic yards of soil was excavated, segregated and stockpiled on site. Approximately 500 cubic yards of this soil exceeded cleanup levels for the contaminants of concern. The 500 cubic yards of contaminated soil was transported off site and thermally remediated. In November 2002, five groundwater monitoring wells were installed to determine groundwater quality.


The facility continues to receive grants through the State of Alaska Financial Assistance Program to fund cleanup activities.



Current Status


After in investigation and cleanup, DEC approved conditional closure, now termed "closure complete - institutional controls," for this site in November 2003.
