Operator Qualification for Contractors: What OQ Does—and Does Not—Require
Contractors often hear that they 'need OQ,' but the details matter. This guide separates what PHMSA requires from assumptions that can waste time or money.
Important disclaimer
Requirements vary by operator, jurisdiction, work scope, and covered function. Confirm requirements with the applicable operator, regulator, and qualified advisors. This guide is informational and is not legal advice.
Quick answer
OQ is about individuals performing covered tasks under an operator's written program. It is not a national contractor certification and does not by itself qualify a company for every operator or project.

Practical OQ checklist
Confirm where OQ applies
- Verify the scope is on a pipeline facility and includes operations or maintenance tasks required under pipeline safety rules.
- Ask the operator for the covered-task list and written OQ program expectations relevant to your scope.
- Document which specific roles in your crews may perform those covered tasks.
Validate qualification method
- Confirm the operator's accepted evaluation methods and record expectations.
- Ensure qualification records are available for each person assigned to covered tasks.
- Check how the operator handles reevaluation intervals and performance deficiencies.
Align procedures and supervision
- Use operator-approved procedures for covered tasks.
- If unqualified individuals are involved, ensure direct observation and direction by a qualified person per operator rules.
- Make sure field supervisors understand when work must pause for qualification gaps.
What varies by operator
- The covered-task list, qualification intervals, and accepted evaluation combinations.
- How contractor records are submitted, audited, and refreshed.
- Rules for equivalent programs or third-party evaluators accepted by that operator.
- Procedures and abnormal operating condition (AOC) expectations for each task.
Common mistakes
- Treating one OQ card or provider result as universally accepted everywhere.
- Assuming contractor personnel can use contractor-developed procedures without operator approval.
- Confusing classroom completion with full task qualification under the operator's program.
- Failing to track reevaluation dates and task-specific qualification records.
Next steps
- Request each target operator's OQ expectations in writing before assigning crews.
- Build an internal matrix of worker, covered task, qualification status, and expiration.
- Coordinate OQ planning with Part 199 applicability for the same roles.
