Description

 

Ride N Shine is located about three miles east of downtown Anchorage. In 1994, four underground storage tanks (USTs) and associated piping were removed. The USTs consisted of two 10,000 gallon gasoline USTs, one 5,000 gallon gasoline UST, and one 500 gallon used oil UST. All UST excavations were backfilled with the excavated soil after it was sampled, and some imported gravel to bring the soils to surface grade. Shortly after the UST removal, the department notified the responsible party that a petroleum release had occurred on the subject site and that a release investigation must be performed. In December of 2002, a release investigation was conducted. This site received cleanup grant funds through the state’s financial assistance program.

 

 

Public Health and Environmental Concerns

 

The contaminants of concern (COCs) are primarily gasoline constituents and solvents including trichloroethylene. Contaminants have impacted both soil and groundwater. A drinking water survey completed in 1992 showed that there were no drinking water wells within ¼ of the site.

 


Current Status

 

The department recently reviewed the site characterization report of the work performed in fall 2002. This site is located adjacent to another leaking underground storage tank (LUST) site. Therefore, onsite contamination resulting from onsite generation must be differentiated from offsite contamination that also appears to have migrated onsite from the off site LUST facility. The department provided comments regarding the report and requested additional investigative work. A workplan was submitted by the consultant and approved by the department to further investigate the groundwater contamination for petroleum and volatile organic compounds (VOCs), and to delineate the extent of the trichloroethylene found in a soil boring near the former used oil tank in fall 2002. The workplan also specified that a monitoring well will be installed near the used oil tank and sampled for VOCs as well as for petroleum.


DEC approved conditional closure for this site in 2004. Details of closure can be found in the "Institutional Controls Report" within the database entry (see link above).
