Cathodic protection adequate?: Unknown
Piping support adequate?: Yes, piping is secured with no sagging/bending.
Tank properly grounded?: No ground wire directly attached to the tank.
Comments: Verify tank is adequately grounded by associated piping/equipment.

GENERAL COMMENTS:
Tank was built and UL listed as “underground tank” and has been installed as a vertical AST and
normal/emergency venting has been added to top of tank.

RECOMMENDATIONS:
Pilot Thomas representatives should verify if any approval had been given to use the underground tank as an
above ground tank. NFPA 30 Chapter 21.3.4 states, “Tanks designed and intended for underground use
shall not be used as aboveground tanks”. The tank has been fitted with normal and emergency venting
however structural integrity is a concern since the tank was not built to sit vertically supported on its flanged
head. Consider cleaning/recoating the moderately corroded areas of the tank shell and roof to prevent further
external corrosion damage. Manage storm water levels in containment to prevent corrosion at base of tank.
