Passage of Internal Inspection Devices
§ 192.150 Passage of Internal Inspection Devices#
(a)Except as provided in paragraphs#
(b)and#
(c)of this section, each new transmission line and each replacement of line pipe, valve, fitting, or other line component in a transmission line must be designed and constructed to accommodate the passage of instrumented internal inspection devices in accordance with NACE SP0102, section 7 (incorporated by reference, see § 192.7).#
(b)This section does not apply to:#
(1)Manifolds;#
(2)Station piping such as at compressor stations, meter stations, or regulator stations;#
(3)Piping associated with storage facilities, other than a continuous run of transmission line between a compressor station and storage facilities;#
(4)Cross-overs;#
(5)Sizes of pipe for which an instrumented internal inspection device is not commercially available;#
(6)Transmission lines, operated in conjunction with a distribution system which are installed in Class 4 locations;#
(7)Gathering lines; and#
(8)Other piping that, under § 190.9 of this chapter, the Administrator finds in a particular case would be impracticable to design and construct to accommodate the passage of instrumented internal inspection devices.#
(c)An operator encountering emergencies, construction time constraints or other unforeseen construction problems need not construct a new or replacement segment of a transmission line to meet subparagraph#
(a)of this paragraph, if the operator determines and documents why impracticability prohibits compliance with subparagraph#
(a)of this paragraph. Within 30 days after discovering the emergency or construction problem the operator must petition, under § 190.9 of this chapter, for approval that design and construction to accommodate passage of instrumented internal inspection devices would be impracticable. If the petition is denied, within 1 year after the date of the notice of denial, the operator must modify that segment to allow passage of instrumented internal inspection devices.#
