AST/UST Closures

Above Ground Storage Tanks (ASTs) and Underground Storage Tanks are unique challenges on construction and re-development sites.  OSG has Ecology certified storage tank de-commissioners who can help you quickly get back to work.  From small home heating oil tanks to very large fueling station tanks, OSG can quickly get the tank lawfully removed and make recommendations on the most efficient way to test and dispose of the surrounding soil.
