Sec. 280.33  Repairs allowed.

    Owners and operators of UST systems must ensure that repairs will 
prevent releases due to structural failure or corrosion as long as the 
UST system is used to store regulated substances. The repairs must meet 
the following requirements:
    (a) Repairs to UST systems must be properly conducted in accordance 
with a code of practice developed by a nationally recognized association 
or an independent testing laboratory.
    Note: The following codes and standards may be used to comply with 
paragraph (a) of this section: National Fire Protection Association 
Standard 30, ``Flammable and Combustible Liquids Code''; American 
Petroleum Institute Publication 2200, ``Repairing Crude Oil, Liquified 
Petroleum Gas, and Product Pipelines''; American Petroleum Institute 
Publication 1631, ``Recommended Practice for the Interior Lining of 
Existing Steel Underground Storage Tanks''; and National Leak Prevention 
Association Standard 631, ``Spill Prevention, Minimum 10 Year Life 
Extension of Existing Steel Underground Tanks by Lining Without the 
Addition of Cathodic Protection.''
    (b) Repairs to fiberglass-reinforced plastic tanks may be made by 
the manufacturer's authorized representatives or in accordance with a 
code of practice developed by a nationally recognized association or an 
independent testing laboratory.
    (c) Metal pipe sections and fittings that have released product as a 
result of corrosion or other damage must be replaced. Fiberglass pipes 
and fittings may be repaired in accordance with the manufacturer's 
specifications.
    (d) Repaired tanks and piping must be tightness tested in accordance 
with Sec. 280.43(c) and Sec. 280.44(b) within 30 days following the 
date of the completion of the repair except as provided in paragraphs 
(d) (1) through (3), of this section:
    (1) The repaired tank is internally inspected in accordance with a 
code of practice developed by a nationally recognized association or an 
independent testing laboratory; or
    (2) The repaired portion of the UST system is monitored monthly for 
releases in accordance with a method specified in Sec. 280.43 (d) 
through (h); or
    (3) Another test method is used that is determined by the 
implementing agency to be no less protective of human health and the 
environment than those listed above.
    (e) Within 6 months following the repair of any cathodically 
protected UST system, the cathodic protection system must be tested in 
accordance with Sec. 280.31 (b) and (c) to ensure that it is operating 
properly.
    (f) UST system owners and operators must maintain records of each 
repair for the remaining operating life of the UST system that 
demonstrate compliance with the requirements of this section.
