(a) Each operator shall, upon completing a Type 1, Type 2A or Type 2 leak repair to its underground facilities, conduct a follow-up inspection at least 14 days after but within 30 days of the repair to validate said repair.
(b) Follow-up inspections are not required for leak repairs completed by the replacement or insertion of an entire length of pipe or service line, or for the repair of leakage caused by contractor or third-party damage, provided a complete reevaluation of the leak area after completion of repairs verifies that no further indications of leakage exist.
(c) Remedial measures such as lubrication of valves or tightening of packing nuts on valves which seal leaks may be considered to be routine maintenance work and do not require a follow-up inspection.
(d) Appropriate records shall be kept.
