(4) Repairs to secondary containment areas of tanks and piping, containment sumps and spill prevention equipment shall be tested for tightness according to the manufacturer’s instructions, a code of practice developed by a Nationally recognized association or independent testing laboratory prior to returning the underground storage tank system to operating status. All other repairs to tanks, containment sumps and piping shall be tightness tested in accordance with § § 245.421(b)(4)(ii), 245.444(2) and 245.445(2) (relating to performance standards for underground storage tank systems; methods of release detection for tanks; and methods of release detection for piping), respectively, prior to placing the underground storage tank system back into service except as provided as follows:
