All hazardous leaks must be remedied at once. 183.2 In addition to other inspections required by this Part, after a high pressure holder has been in service for a period of ten years, and at intervals not exceeding ten years thereafter, a complete and thorough internal and external inspection shall be made and reported upon by competent inspectors who are selected by the utility and are agreeable to the Commission. A copy of the report shall be provided to the Commission. 183.3 In lieu of an internal inspection, when it is not practical to enter the holder, a sufficient number of plugs shall be cut from, or holes bored in, the shell at points believed most subject to internal corrosion, to enable examination for corrosion. The interior of at least one container of a holder constructed entirely of pipe and fittings shall be inspected by removing the end closures and entering the container. 183.4 As an alternative to the above requirements to enter the container, or to cut plugs or bore holes in the holder, a nondestructive test procedure such as ultrasonic testing may be used. The test instrument must be calibrated to measure the wall thickness of the steel plates so that the error of indication shall not vary more than plus or minus two thousandths (±0.002) of an inch. 183.5 When such inspections determine that the holders are in a defective and hazardous condition, they shall be taken out of service until repaired and placed in a safe workable condition. All others in the same group shall immediately be inspected and repaired if found defective. If any portion of the shell of a high pressure holder is located underground and exposed to the soil, inspection of its exterior for corrosion and leaks shall be made by suitable representative excavations at the time of the inspection. ## Provenance - Official: Yes - Source: - Source ID: `ca-cpuc-go-112-f` - SHA-256: `29ee88744c023e94f71aee3ff4f2d01dfdf0145af86aa80720e43b42f811194a` - Retrieved: 2026-08-20T06:57:47.831Z - Exported: 2026-08-24T20:32:20.201Z - Document slug: `ca-cpuc-go-112-f-183` ### Source metadata ```json { "jurisdiction": "US-CA", "corpus": "CPUC General Order 112-F", "unit": "183", "subpart": "SUBPART E GAS HOLDERS", "legalScope": "State gas-pipeline safety rules governing design, construction, testing, operation, and maintenance of covered gas gathering, transmission, distribution, LNG, gas-holder, and petroleum-gas vessel-station facilities, plus reporting and whistleblower requirements.", "applicabilityCaveat": "General Order 112-F applies according to its own definitions and the California Public Utilities Commission's jurisdiction, including covered natural-gas transmission and distribution systems, master-meter systems, and covered LPG distribution systems.
