# Installation of Pipe in a Ditch **Citation:** 192.319 **Type / status:** regulation / current **Agency:** Arkansas Public Service Commission **Effective:** Not stated **Published:** Not stated § 192.319 Installation of Pipe in a Ditch (a) When installed in a ditch, each transmission line that is to be operated at a pressure producing hoop stress of 20 percent or more of SMYS must be installed so that the pipe fits the ditch so as to minimize stresses and protect the pipe coating from dama ## Document text § 192.319 Installation of Pipe in a Ditch (a) When installed in a ditch, each transmission line that is to be operated at a pressure producing hoop stress of 20 percent or more of SMYS must be installed so that the pipe fits the ditch so as to minimize stresses and protect the pipe coating from damage. (b) Each ditch for a transmission line or main must be backfilled in a manner that: (1) Provides firm support under the pipe; and (2) Prevents damage to the pipe and pipe coating from equipment or from the backfill material. (c) Promptly after a ditch for an onshore steel transmission line is backfilled (if the construction project involves 1,000 feet or more of continuous backfill length along the pipeline), but not later than 6 months after placing the pipeline in service, the operator must perform an assessment to assess any coating damage and ensure integrity of the coating using direct current voltage gradient (DCVG), alternating current voltage gradient (ACVG), or other technology that provides comparable information about the integrity of the coating. Coating surveys must be conducted, except in locations where effective coating surveys are precluded by geographical, technical, or safety reasons. (d) An operator must notify PHMSA in accordance with § 192.18 at least 90 days in advance of using other technology to assess integrity of the coating under paragraph (c) of this section. (e) An operator of an onshore steel transmission pipeline must develop a remedial action plan and apply for any necessary permits within 6 months of completing the assessment that identified the deficiency. An operator must repair any coating damage classified as severe (voltage drop greater than 60 percent for DCVG or 70 dBµV for ACVG) in accordance with section 4 of NACE SP0502 (incorporated by reference, see § 192.7) within 6 months of the assessment, or as soon as practicable after obtaining necessary permits, not to exceed 6 months after the receipt of permits. (f) An operator of an onshore steel transmission pipeline must make and retain for the life of the pipeline records documenting the coating assessment findings and remedial actions performed under paragraphs (c) - (e) of this section. ## Provenance - Official: Yes - Source: - Source ID: `ar-car-pipeline-safety` - SHA-256: `aa5dce33f61f2f430648bb7ca48d6899a401471a4d6fc82baf65c34fc40650ed` - Retrieved: 2026-08-12T08:10:37.612Z - Exported: 2026-08-25T05:15:29.963Z - Document slug: `ar-car-23-500-192-319` ### Source metadata ```json { "jurisdiction": "US-AR", "subject": "intrastate-gas", "caveats": { "exactScope": "The searchable corpus contains every current numbered section, the code-wide definitions, and every operative appendix in official 23 CAR Part 500, plus direct pipeline rules 15 CAR sections 275-406 and 275-504.
