Passage of Internal Inspection Devices [49 CFR 192.150]

(A)A. Except as provided in Subsections 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 §507). [49 CFR 192.150(a)] .#

(B)B. This Section does not apply to: [49 CFR 192.150(b)]#

(1)1. manifolds; [49 CFR 192.150(b)(1)#

(2)2. station piping such as at compressor stations, meter stations, or regulator stations; [49 CFR 192.150(b)(2)]#

(3)3. piping associated with storage facilities, other than a continuous run of transmission line between a compressor station and storage facilities; [49 CFR 192.150(b)(3)]#

(4)4. cross-overs; [49 CFR 192.150(b)(4)]#

(5)5. sizes of pipe for which an instrumented internal inspection devise is not commercially available; [49 CFR 192.150(b)(5)]#

(6)6. transmission lines, operated in conjunction with a distribution system which are installed in Class 4 locations; [49 CFR 192.150(b)(6)]#

(7)7. offshore transmission lines, except transmission lines 10 3/4 inches (273 millimeters) or more in outside diameter on which construction begins after December 28, 2005, that run from platform to platform or platform to shore unless [49 CFR 192.150(b)(7)] :#

(a)a. platform space or configuration is incompatible with launching or retrieving instrumented internal inspection devices; or [49 CFR 192.150(b)(7)(i)]#

(b)b. if the design includes taps for lateral connections, the operator can demonstrate, based on investigation or experience, that there is no reasonably practical alternative under the design circumstances to the use of a tap that will obstruct the passage of instrumented internal inspection devices; [49 CFR 192.150(b)(7)(ii)]#

(8)8. Gathering lines; and [49 CFR 192.150(b)(8)]#

(9)9. Other piping that, under 49 CFR Part 190.9 and LAC 43:XI.Subpart 3 the commissioner/administrator finds in a particular case would be impracticable to design and construct to accommodate the passage of instrumented internal inspection devices. [49 CFR 192.150(b)(9)]#

(C)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 Subsection A of this Section, if the operator determines and documents why an impracticability prohibits compliance with Subsection A of this Section. Within 30 days after discovering the emergency or construction problem the operator must petition, under 49 CFR Part 190.9 and LAC 43:XI.Subpart 3 for approval that design and construction to accommodate passage of instrumented internal inspection devices would be impracticable. If the petition is denied, within one year after the date of the notice of the denial, the operator must modify that segment to allow passage of instrumented internal inspection devices. [49 CFR 192.150(c)]#
