Gas Regulator Station Inspection Checklist [FREE PDF]

Gas regulator station inspections are required under 49 CFR Part 192 to ensure safe operation of pressure regulation equipment, overpressure protection devices, and emergency shutdown systems. Routine inspections help prevent catastrophic failures, uncontrolled pressure events, and gas release incidents that endanger workers and the public. This checklist aligns with OSHA 29 CFR 1910.269, NFPA 54, and applicable FERC and DOE safety orders for natural gas infrastructure.

  • Industry: Natural Gas
  • Frequency: Monthly
  • Estimated Time: 45-60 minutes
  • Role: Utility Inspector
  • Total Items: 38
  • Compliance: 49 CFR Part 192 - Transportation of Natural and Other Gas by Pipeline, OSHA 29 CFR 1910.269 - Electric Power Generation, Transmission, and Distribution, NFPA 54 - National Fuel Gas Code, FERC Order 745 - Demand Response Compensation, DOE Safety Order DOE O 440.1B - Worker Protection Program

Site Security and Access Control

Verify that physical security measures, perimeter controls, and access restrictions are in place and functional.

  • Is the station perimeter fence intact with no visible damage or breaches?
  • Are all gates secured with approved locking mechanisms?
  • Are warning and safety signs posted and legible at all entry points?
  • Is the access log current and signed by all recent visitors?
  • Are unauthorized intrusion or tampering signs absent from the site?

Pressure Regulation Equipment

Inspect pressure regulators, monitors, and associated piping for proper operation and integrity.

  • Is the primary pressure regulator operating within the designed set-point range?
  • Is the monitor regulator functional and set above the primary regulator set point?
  • What is the current inlet pressure reading (psig)?
  • What is the current outlet pressure reading (psig)?
  • Are all pressure gauge faces clean, undamaged, and reading within calibrated range?
  • Are all regulator vents clear of obstructions and terminated safely outdoors?

Overpressure Protection Devices

Verify that relief valves, slam-shut valves, and other overpressure protection devices are operational and properly configured.

  • Is the pressure relief valve (PRV) within its certified relief set-point?
  • Has the PRV been tested within the required inspection interval?
  • Is the slam-shut valve (SSV) set to trip at the correct overpressure value?
  • Is the PRV discharge stack free of blockage, corrosion, or water ingress?
  • Are all overpressure protection test records current and accessible on site?

Leak Detection and Gas Safety

Conduct leak survey and verify gas detection equipment operation throughout the station.

  • Has a combustible gas detector survey been performed at all joints and connections?
  • Are fixed gas detection sensors calibrated and showing no alarm conditions?
  • Is the gas detector reading within acceptable limits (% LEL)?
  • Are all pipe joints, flanges, and fittings free of visible gas leaks or odorant smell?
  • Is emergency gas shutoff clearly marked and accessible within 3 seconds of approach?

Piping and Structural Integrity

Inspect above-ground piping, supports, coatings, and structural components for corrosion, damage, or deterioration.

  • Is all aboveground piping free of visible corrosion, pitting, or coating damage?
  • Are all pipe supports, clamps, and hangers structurally sound and properly secured?
  • Is cathodic protection test point showing acceptable protection potential?
  • Are expansion loops or flexible connections free of stress, deformation, or fatigue cracking?
  • Is any evidence of ground movement, erosion, or soil settlement visible around buried pipe risers?
  • Attach photo documentation of any identified corrosion or structural deficiencies?

Electrical and Instrumentation Systems

Verify electrical supply, SCADA, telemetry, and instrumentation systems are functional and safely maintained.

  • Is electrical supply to the station within acceptable voltage tolerance (+/-10%)?
  • Is the SCADA or remote telemetry unit (RTU) communicating correctly with the control center?
  • Are all electrical panels, junction boxes, and conduits sealed against moisture and pests?
  • Is the UPS or backup power system charged and tested within the last maintenance cycle?
  • Are all instrumentation calibration stickers current and within expiry dates?

Emergency Response Readiness

Confirm that emergency equipment, documentation, and communication systems are in place and ready for use.

  • Is the emergency response plan (ERP) current, on-site, and within annual review date?
  • Are fire extinguishers present, inspected monthly, and within hydrostatic test dates?
  • Is PPE (gloves, gas monitor, hard hat, safety glasses) available and in serviceable condition?
  • Is the emergency contact list posted and includes gas control center, local fire, and police?
  • Are any corrective actions or open work orders from the previous inspection still outstanding?
  • Provide summary of findings, corrective actions required, or observations from this inspection?
