Sustainable Group, Inc.

Scope Of Work

For this project, Sustainable Group provided Underground Storage Tank (UST) expertise to Sierra Pacific Industries and DS Ventures Inc. to ensure the proper removal and disposal of a 2,000 gallon gasoline underground storage tank at the now decommissioned Camino Sawmill. Specifically, Sustainable Group oversaw the proper cleaning and removal of all remaining product from the tank; the triple rinsing of the tank; the inerting of the tank with “dry ice” to keep oxygen levels below 10% within the atmosphere of the tank; the actual tank extraction and finally, the final tank disposal. Since the California Department of Toxic Substances Control considers excavated tanks which held hazardous material to be hazardous waste, Sustainable Group assisted the project team with identifying one of the few remaining facilities that will take excavated tanks for processing. This assistance ensured the tank was indeed disposed of properly. Sustainable Group completed this project on budget and on an accelerated timeline without incident of any kind.
