Approximately 500 cubic yards of stockpiled soil was spread and aerated behind the store, then fertilized and seeded to help control erosion.
Goldstream General Store is located on Goldstream Road, approximately ten miles outside Fairbanks. Leaking product around the pump island and near one of the two 6,000-gallon tanks was detected in January 1992. The two tanks that contained diesel and unleaded gasoline were removed in September 1993.
This site has received financial grants from the DEC Financial Assistance Program to conduct assessment, closure and removal of tanks, and remediation. As of January 2000, benzene was the only tested contaminant that remained at concentrations above the most stringent cleanup levels. Stockpiled soils have been tilled and aerated to attain applicable cleanup levels.
Seeding was successful, as seen in this picture taken in mid-July 2003.
Approximately 800 cubic yards of soil was removed and stockpiled during excavation and removal of the tanks. 300 cubic yards of the contaminated soil was placed back into the excavation to prevent loss of structural integrity to the laundromat building on site. Pump island piping has also been replaced. Concentrations of benzene, BTEX, gasoline and diesel range organics in soil were as high as 13 parts per million (ppm), 321 ppm, 772 ppm and 11,600 ppm, respectively.
During the summer of 2003, stockpiled soil was aerated and spread behind the store, then hydroseeded to minimize erosion. The property owner’s consultant submitted a final work plan to sample stockpiled soil and perform a soil vapor analysis to assess potential impacts to indoor air quality in the laundromat. This work was covered under a final grant from the Financial Assistance Program. The intent was to perform all work necessary to achieve a NFRAP (No Further Remedial Action Planned).
Conditional closure, now called "Cleanup Complete-Institutional Controls" was approved in December of 2004.
