# Pressure Limiting and Regulating Stations: Inspection and Testing **Citation:** 192.739 **Type / status:** regulation / current **Agency:** Arkansas Public Service Commission **Effective:** Not stated **Published:** Not stated § 192.739 Pressure Limiting and Regulating Stations: Inspection and Testing (a) Each pressure limiting station, relief device (except rupture discs), and pressure regulating station and its equipment must be subjected, at intervals not exceeding 15 months, but at least once each calendar year, to in ## Document text § 192.739 Pressure Limiting and Regulating Stations: Inspection and Testing (a) Each pressure limiting station, relief device (except rupture discs), and pressure regulating station and its equipment must be subjected, at intervals not exceeding 15 months, but at least once each calendar year, to inspections and tests. These inspections and tests shall include the following: (1) Pressure regulating devices. (i) Each regulator must be inspected to ensure it is in good working order, controls pressure and capacity within acceptable limits for the system in which it is installed. (ii) Shuts off pressure within acceptable limits. (iii) Second stage regulator will withstand and control first stage inlet pressure if a relief valve is not installed between regulators. (iv) Properly installed control lines, controllers, actuators and protected from conditions that may prevent proper operation. (v) Except as provided in paragraph (b) of this section, set to control or relieve at the correct pressure consistent with the pressure limits of § 192.201(a); and (2) Pressure limiting and relief devices. (i) Monitor regulators tested for proper operating parameters. (ii) Except as provided in paragraph (b) of this section set to control or relieve at the correct pressure consistent with the pressure limits of § 192.201 (a); and (iii) Vent stacks are free of obstructions, properly routed, vented outside of building and vents adequately covered. (iv) Block valves connecting relief devices to a system shall be locked in the open position and block valves in manually-fed above ground bypasses shall be locked in the closed position. (b) For steel pipelines whose MAOP is determined under § 192.619(c), if the MAOP is 60 p.s.i. (414 kPa) gage or more, the control or relief pressure limit is as follows: If the MAOP produces a hoop Then the pressure limit is: stress that is: Greater than 72 percent of SMYS MAOP plus 4 percent Unknown as a percentage of SMYS A pressure that will prevent unsafe operation of the pipeline considering its operating and maintenance history and MAOP ## Provenance - Official: Yes - Source: - Source ID: `ar-car-pipeline-safety` - SHA-256: `4e5184225ad4257be1f9758a15fc441361738e5f0f71bc9e4bf5d44056f56f90` - Retrieved: 2026-08-12T08:10:37.612Z - Exported: 2026-08-26T02:18:29.760Z - Document slug: `ar-car-23-500-192-739` ### 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.
