Underground storagetank removal
Tank removal is a regulated closure: cleaning, excavation, soil sampling and paperwork. Alliance handles the hazmat side from start to closure.

A tank closure,not just a dig
In California, underground storage tank removal is overseen by the local regulatory agency, typically the Certified Unified Program Agency (CUPA), and requires permits, inspections and sampling. The tank has to be emptied and cleaned, removed, and the surrounding soil checked for leaks before the site can be closed.
Alliance cleans and removes tanks, excavates and disposes of contaminated soil where sampling calls for it, and provides the documentation the closure requires. Tank cleaning for industrial, utility and municipal clients is one of Alliance's core services.
