Specialty Tanks






Class A Certification

If there is no documentation for a tank that was closed in place and filled with water prior to 1971, then a site assessment must be performed and the appropriate documentation filed with Commerce.  


It is suggested that if you have any questions in regard to the above issues about tank closure in place and filling tanks with water that you contact Commerce for guidance.


A tank and piping system can only be cleaned and removed from a facility by individual(s) who have been certified by Commerce as a “Tank System Remover-Cleaner.”   The requirements for certification can be found at the Commerce website.
