years after lining and at least every 5 years thereafter, the lined tank must be
inspected by a trained professional and found to be structurally sound with the
lining still performing according to original design specifications. Make sure
the professional performing the inspection follows the rules and guidelines as
explained in BUSTR’s “Procedures for the Periodic Inspection of Lined
Underground Storage Tanks.”
Keep records of the inspection (as
specified by BUSTR and in industry standards for lining inspections).

If you chose the combination of
internal lining and cathodic protection for meeting corrosion protection
requirements on your UST, you may not have to meet the periodic inspection
requirement for the lined tank. However, you must always meet the requirements
for checking and testing your cathodic protection system as described in the
corrosion protection “Frank the Tanks” describing impressed current
and sacrificial anodes. The 10-year
and subsequent 5-year inspections of the lined tank are not required if the
integrity of the tank was ensured when cathodic protection was added.
