Can a previously used AST be installed?
A. Yes. The applicable rules do not mandate that a new AST be installed. However, a used AST is subject to compliance with all of the rules and criteria applicable to a new AST (i.e., listed by a recognized testing agency, properly vented, provided with secondary containment, etc.). Furthermore, the OSFM requires that the tank owner or installer provide evidence that a used tank has been re-inspected or retested prior to installation.
