(v) Repairs to secondary containment areas of tanks and piping used for interstitial monitoring and to containment sumps used for interstitial monitoring of piping shall have the secondary containment tested for tightness according to the manufacturer's instructions or a code of practice developed by a nationally recognized association or independent testing laboratory within 30 days following the date of completion of the repair. All other repairs to storage tank systems shall be tightness tested in accordance with Sections 14(g) and 16(b) within 30 days following the date of the completion of the repair unless:

(A) The repaired storage tank system is internally inspected in accordance with a code of practice listed in this Section; or

(B) The repaired portion of any UST system is monitored monthly for releases in accordance with a method specified in Section 16(c) through (j); or

(C) Another test method is used that is determined by the department, pursuant to Section 33, to be no less protective of human health and the environment than those listed above.

(D) The following codes of practice may be used to comply with paragraph (a)(v) of this Section:

(b) All owners and/or operators of repaired UST systems shall ensure the modifications meet the performance standards for design and repair as set forth in Section 6.

(c) Costs associated with remediation of any release from a storage tank system during tank installation or repair work by a tank installer, tester, owner and/or operator, etc., are not eligible for the state's corrective action account funds.

(d) Any time steel connected piping is repaired or modified by replacing the pipe with a non-corrodible pipe, all of the connected piping on that run shall be replaced. Any time steel piping that is not cathodically protected is repaired or replaced, the entire run of pipe shall be replaced with a non-corrodible pipe.

(e) Whenever the integrity of the primary or secondary wall of a double-wall tank has been compromised, repairs shall be made immediately in accordance with the tank manufacturer's recommendations. If the tank cannot be repaired, it shall be permanently closed in accordance with Section 31.

(f) Within 30 days following any repair to spill or overfill prevention equipment, the repaired spill or overfill prevention equipment shall be tested or inspected, as appropriate, in accordance with Section 10(d) to ensure it is operating properly.
