(2) Any tank failing to meet the testing criteria of paragraph (1) of this subsection shall be repaired and retested within 15 days.

(3) Testing required in paragraph (1) of this subsection shall be conducted in accordance with the following test methods, as appropriate:
(A) Test Method 27 (40 Code of Federal Regulations (CFR) 60, Appendix A) for determining vapor-tightness of gasoline delivery tank using pressure-vacuum test such that the pressure in the tank must change no more than three inches of water (0.75 kPa) in five minutes when pressurized to a gauge pressure of 18 inches of water (4.5 kPa) and when evacuated to a vacuum of six inches of water (1.5 kPa); or

(B) minor modifications to these test methods approved by the executive director.

(4) For tank-truck tanks which are filled with non-gasoline VOC at a facility subject to § 115.214(a)(1)(C) of this title, annual testing using the leakage test method described in 49 CFR 180.407(h) for specification cargo tanks is an acceptable alternative to Test Method 27 ( 40 CFR 60, Appendix A).
