Rule 17, Section 280.33 is amended to read as
						follows:
Section 280.33. Owners and operators of UST systems shall
						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 all of the following requirements:
(a) Alterations to UST systems for product
					 compatibility, repairs, or upgrades must be properly conducted in accordance
					 with the provisions of subsections 280.20(d) and 280.21(b) and (c).
(b) Repairs to fiberglass-reinforced plastic
					 tanks must be made in accordance with the provisions of subsection
					 280.20(d).
(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 that have released
					 product must be replaced or repaired in accordance with the manufacturer's
					 specifications. The implementing agency may require that replacements or
					 repairs be made where damage to pipe sections or fittings is discovered and
					 presents a significant risk of release.
(d) Repairs to secondary containment areas of
					 tanks and piping used for interstitial monitoring and to containment sumps used
					 for interstitial monitoring of piping must have the secondary containment
					 tested for tightness according to the manufacturers instructions, a code of
					 practice developed by a nationally recognized association or independent
					 testing laboratory, or in compliance with these rules, within 30 days following
					 the date of completion of the repair. Repaired or upgraded tanks and piping
					 must be tightness-tested in accordance with the provisions of sections
					 280.43(c) and 280.44(b) within 30 days after the date of the completion of the
					 repair or upgrade. Exceptions may be made to this requirement if the repaired
					 tank is internally inspected in accordance with a code of practice developed by
					 a nationally recognized association or an independent testing laboratory; the
					 repaired or upgraded portion of the tank system is monitored monthly for
					 release in accordance with a method specified in section 280.43(d) to (i); or
					 another test method that is determined by the department to be at least as
					 protective of human health and the environment as the protections specified in
					 sections 280.43(c) and 280.44(b).
(e) Within 6 months after the repair of any
					 cathodically protected UST system, the cathodic protection system must be
					 tested in accordance with sections 280.31(b) and (c) to ensure that it is
					 operating properly.
(f) UST system
					 owners and operators shall maintain records, in accordance with section 280.34,
					 of each repair for the remaining operating life of the UST system that
					 demonstrate compliance with the requirements of this section.
(g) Within 30 days following any repair to
					 spill or overfill prevention equipment, the repaired spill or overfill
					 prevention equipment must be tested or inspected, as appropriate, in accordance
					 with section 280.35 to ensure it is operating properly.
