(1) Repairs.
(a) Repairs shall be performed if any component of a storage tank system has:
1. A release or discharge or has contributed to a release or discharge of a regulated substance, or
2. The presence of groundwater in the interstice of an underground double-walled pipe, or
3. An operational or structural problem that could potentially result in a release or discharge, or lead to the presence of water in the interstice of a storage tank or integral piping other than condensate.
(b) The storage tank system shall immediately cease operating and accepting deliveries, if:
1. Repairs are required for any component of a storage tank system; and,
2. The nature of the repair activities or the condition of the component cannot be otherwise isolated from the storage tank system. The restrictions against operating the storage tank system shall not apply if the storage tank system contains fuels used solely for the generation of electricity by an electric utility as defined in Florida Statutes Chapter 366, where the removal of the storage tank system from use would result in the shutdown of electrical generating units serviced by the storage tank system; and
3. The condition of the component results in an on-going discharge, pursuant to Fl. Admin. Code R. 62-762.441
(c) Repairs shall be made:
1. To restore the structural integrity of the storage tank system and in a manner that will prevent releases or discharges from structural failure or corrosion for the remaining operational life of the storage tank system; and,
2. In accordance with manufacturer’s specifications and applicable reference requirements.
(d) Repaired components shall be integrity tested for liquid tightness before being placed back into operation.
(e) Piping that is damaged or that has caused a discharge of a regulated substance shall be replaced or repaired. Repairs of pipe sections, sump penetration fittings and pipe fittings shall be made in accordance with applicable requirements in subsections 62-762.502(3) and (4), F.A.C. Replacement of additional lengths of single-walled piping in contact with the soil are exempt from the requirements for secondary containment, provided that:
1. The piping system does not have, or will not have to install secondary containment until the deadlines established in Fl. Admin. Code R. 62-762.502; and,
2. The length of replacement or additional piping is less than 25 percent of the total length of the existing integral piping for the individual tank, or 100 feet, whichever is more for each repair event.
(f) A storage tank system that requires repair, but cannot be repaired within 90 days to operate in accordance with the requirements of this chapter, shall be taken out-of-service in accordance with subsection 62-762.802(2), F.A.C.
