Key Takeaways
- PHMSA does not specify a fixed requalification interval — the operator is responsible for determining what is appropriate for each covered task.
- The operator must define the requalification interval, the method of requalification, and maintain documentation for each qualified individual.
- Common requalification intervals used in the industry are 1 year, 3 years, and 5 years depending on the task and company policy.
- Tracking requalification due dates is essential — an expired qualification is an audit finding if the individual continues performing that covered task.
What PHMSA Actually Says About Requalification
PHMSA does not say "every 3 years" or set any specific requalification interval. What the regulation says is that requalification must occur at intervals not to exceed what the operator determines is appropriate.
That means the company must make a deliberate decision for each covered task: how long is a qualification valid? The answer needs to be documented in the organization's OQ program, and then it needs to be followed consistently.
Expert Note: The flexibility here is intentional — PHMSA recognizes that a simple valve operation and a complex welding task shouldn't necessarily have the same requalification frequency. But that flexibility also means the operator owns the decision and has to defend it.
What Organizations Are Required to Define
For each covered task, the operator's OQ program must establish:
- The requalification interval (how long a qualification remains valid)
- The method of requalification (written test, observed performance, oral exam, simulation, etc.)
- Documentation of each requalification event, including the date, method, evaluator, and result
What Most Organizations Actually Use
In practice, most pipeline operators and utilities settle on requalification intervals that fall into one of three common categories depending on the task type, risk level, and company policy:
- 1 year — often used for higher-frequency or higher-risk tasks
- 3 years — the most commonly used interval across a broad range of covered tasks
- 5 years — sometimes used for lower-frequency tasks with stable procedures
Why Tracking Requalification Due Dates Is Critical
An individual whose qualification has expired should not be performing that covered task. If they are — and an inspector finds it — that's an audit finding. The issue isn't just paperwork; performing a covered task without a current qualification is a violation of the OQ rule.
Many organizations have the right policies in place but fail at tracking. Qualification dates sit in spreadsheets, the due dates aren't surfaced proactively, and requalifications happen late or get missed entirely. That's a documentation problem with real compliance consequences.
What Cambri Compliance Tracks for OQ Requalification
Cambri Compliance helps organizations stay on top of requalification requirements by tracking:
- Qualification date — when the individual was last evaluated
- Requalification interval — the operator-defined period for the covered task
- Expiration date — calculated automatically from the qualification date and interval
- Requalification due date — so upcoming expirations surface before they become violations
- Qualification status — current, expiring soon, or expired
