Strengthening Damage Prevention: PHMSA Pushes Operators Toward More Aggressive Excavation Risk Management

In its latest advisory tied to National Safe Digging Month, PHMSA is reinforcing a familiar message with sharper operational expectations: excavation damage remains one of the leading threats to pipeline safety, and operators need to tighten coordination, improve locating accuracy, and treat even "near-miss" events as integrity threats.

ADB–2026–05 does not introduce new regulatory requirements, but it clearly signals where PHMSA expects operators to raise their game—particularly in locator performance, stakeholder coordination, and post-damage response.

Why This Matters

Excavation damage continues to be a top cause of pipeline incidents across both gas and hazardous liquid systems. What stands out in this advisory is PHMSA's focus on execution quality , not just program existence.

Most operators already have damage prevention programs, 811 participation, and public awareness efforts in place. This bulletin goes further, emphasizing adoption of CGA best practices, enhanced locator training and oversight, proactive White Lining, speed and effectiveness of response to strikes, integrity verification after near-misses, and public awareness that actually drives behavior change.

PHMSA is also reminding operators of existing regulatory obligations under 49 CFR §§ 192.613 and 195.401, reinforcing that third-party excavation risk is a core component of required surveillance activities.

Move Beyond Compliance to Precision in Locating

PHMSA is explicitly pointing operators to CGA Best Practices. The expectation is that operators validate not just that locates are performed—but that they are accurate, timely, and reliable.

Operators should consider auditing locate accuracy rates (not just completion metrics), evaluating tolerance zone practices, and reviewing damage history tied to mis-locates.

Increase Training and Oversight of Locators

PHMSA is signaling concern around locator performance, particularly in high-growth areas. Operators should review and enhance training of internal and contractor locators, audit both internal and third-party locators, and ensure adequate time, staffing, and tools for accurate marking.

Push Pre-Construction Coordination Upstream

The advisory highlights two underutilized but high-impact practices: white lining excavation areas and pre-construction meetings for large projects. Operators should engage earlier in project planning and ensure excavators understand depth, pressure, and emergency protocols.

Rethink Public Awareness Programs

PHMSA is clearly raising expectations for public awareness effectiveness—not just outreach volume. Operators should expand beyond traditional communication channels, provide clear and actionable guidance on recognizing and responding to pipeline releases, and use performance metrics to evaluate effectiveness.

Treat Near Misses as Integrity Threats

One of the strongest operational signals in this advisory: if a pipeline is struck or scraped—even without a leak—conduct a thorough inspection. Mechanical damage can create latent defects that may evolve into future stress corrosion cracking or delayed failure. Operators should ensure clear procedures for post-strike evaluation and integration of these events into IM/DIMP/TIMP risk models.

Strengthen Patrol Effectiveness

PHMSA reinforces the role of patrols as a frontline defense against excavation damage, including identifying unauthorized excavation activity and ensuring that excavation activity does not pose a threat to the pipeline.

Final Takeaway

ADB–2026–05 is less about new requirements and more about raising the standard of execution across damage prevention programs. Accurate locates matter more than completed locates. Near-misses matter as much as incidents. Public awareness must drive behavior—not just check a box.

For operators, this is a good time to step back and ask a hard question: Is your damage prevention program truly reducing risk in the field—or just meeting minimum expectations on paper?
