Pipeline Right-of-Way Patrol Inspection Checklist [FREE PDF]

Pipeline right-of-way patrol inspections are mandated under API 1160 and 49 CFR Part 195 to identify encroachments, corrosion indicators, leaks, and third-party activity that could compromise pipeline integrity. Operators must document patrol frequency, findings, and corrective actions to satisfy PHMSA integrity management program requirements. This checklist standardizes field observations to ensure consistent, defensible records for regulatory review and incident prevention.

  • Industry: Pipeline Operations
  • Frequency: Weekly
  • Estimated Time: 45-75 minutes
  • Role: Pipeline Inspector
  • Total Items: 42
  • Compliance: API 1160 Managing System Integrity for Hazardous Liquid Pipelines, 49 CFR Part 195 Transportation of Hazardous Liquids by Pipeline, 49 CFR Part 192 Transportation of Natural Gas by Pipeline, EPA 40 CFR 112 SPCC Spill Prevention Control and Countermeasure, API RP 14C Production Safety Systems

ROW Markers and Signage

Verify pipeline markers, warning signs, and boundary indicators are present, legible, and correctly positioned along the right-of-way.

  • Are all pipeline markers visible and undamaged at required intervals?
  • Do markers display required information including operator name and emergency contact number?
  • Are boundary markers at ROW edges intact and legible?
  • Have any markers been removed, vandalized, or obscured by vegetation?
  • Are aerial marker balls present and intact at road and waterway crossings?

Encroachment and Third-Party Activity

Identify unauthorized construction, excavation, or land use within or adjacent to the pipeline right-of-way.

  • Is there any evidence of unauthorized excavation or digging within the ROW?
  • Are there any new structures, buildings, or permanent installations encroaching on the ROW?
  • Is there evidence of agricultural tiling, drainage work, or irrigation installation on the ROW?
  • Are there any vehicles, equipment, or machinery operating on the ROW without apparent authorization?
  • Have any crossings or encroachment permits been verified for observed third-party work?
  • Describe any encroachment or third-party activity observed during patrol?

Surface Conditions and Erosion

Evaluate ROW surface for erosion, subsidence, washouts, and conditions that may indicate pipeline movement or exposure.

  • Is there any evidence of soil erosion or washout that may expose the pipeline?
  • Are there visible signs of ground subsidence, sinkholes, or soil settlement along the ROW?
  • Is the pipeline exposed above ground at any unintended location?
  • Are drainage ditches and culverts along the ROW clear and functioning?
  • Is there evidence of landslide, slope movement, or bank erosion near the pipeline?

Vegetation Management

Assess ROW vegetation for compliance with operator clearing standards and identification of conditions that obstruct inspection or damage pipeline coating.

  • Is vegetation on the ROW maintained within operator-specified height limits?
  • Are there any trees or deep-rooted plants growing within the ROW that could damage the pipeline?
  • Is vegetation cleared adequately at all valve sites and above-ground appurtenances?
  • Is there evidence of invasive species or noxious weeds requiring treatment?
  • Are there areas where vegetation obscures pipeline markers from road or aerial view?

Leak Detection and Environmental Observations

Document sensory and visual observations that may indicate a pipeline leak, spill, or environmental release.

  • Is there any unusual odor consistent with petroleum, natural gas, or H2S along the ROW?
  • Is there visible product staining, sheen, or discoloration of soil or water on or near the ROW?
  • Is there dead or stressed vegetation in a pattern that may indicate a subsurface release?
  • Are there any bubbling water features, oily sheen on streams, or discolored watercourses near the ROW?
  • Was a combustible gas detector or H2S monitor used during this patrol segment?
  • Provide any additional observations regarding potential leaks or environmental concerns?

Above-Ground Facilities and Valve Sites

Inspect above-ground pipeline appurtenances including valves, vents, drains, and cathodic protection equipment encountered along the patrol route.

  • Are all valve boxes and valve vaults accessible, locked, and in good condition?
  • Are cathodic protection test stations intact, accessible, and clearly identified?
  • Are above-ground piping, flanges, and fittings free of visible corrosion or coating damage?
  • Are pressure relief device vents and drains unobstructed?
  • Is fencing, lighting, and security at any above-ground valve stations adequate?

Road, Rail, and Water Crossings

Evaluate conditions at all road, railroad, and waterway crossings encountered during patrol for evidence of stress, exposure, or damage.

  • Are road crossing warning signs present and visible on both sides of each road crossing?
  • Is there evidence of scour, undermining, or bank erosion at waterway crossings?
  • Are railroad crossing casings and markers intact and undamaged?
  • Is there evidence of pipeline movement, displacement, or spanning at any crossing?
  • Document milepost locations and conditions of all crossings inspected during this patrol?

Patrol Closeout and Corrective Actions

Summarize patrol findings, document any deficiencies identified, and record corrective action notifications made during or after the patrol.

  • Were any deficiencies or anomalies identified during this patrol that require corrective action?
  • Were all required milepost segments patrolled and recorded during this inspection?
  • Were any emergency notifications or regulatory reports made during this patrol?
  • Provide a summary of all findings, notifications, and corrective actions initiated during this patrol?
  • Attach photos taken during patrol?
