What counts as a covered task
Under 49 CFR 192.801, an operator must qualify every individual performing covered tasks. A covered task is an activity performed on a pipeline facility, an operations or maintenance task, performed as a requirement of Part 192, and one that affects the operation or integrity of the pipeline. The four-part test matters because it pulls in contractor crews: a service technician who works on pipeline facilities, does maintenance work required by the rules, and touches system integrity is performing covered tasks even when the badge on the shirt belongs to another company.
How qualification can be shown
Section 192.803 is specific about the evidence. Qualification may be shown by written examination, oral examination, work performance history review, observation during on-the-job performance, on-the-job training, simulations, or other documented forms of assessment. Qualified means the individual has been evaluated and can perform the assigned covered tasks, and can recognize and react to abnormal operating conditions. The flexibility cuts both ways: an operator can use many evaluation methods, but each one must be documented, because the record is what a PHMSA inspection checks.
The written program is the backbone
Section 192.805 requires each operator to have and follow a written qualification program, and 192.805(g) requires the program to identify the covered tasks and the intervals at which evaluation of qualifications is needed. Hazardous liquid lines carry the same obligation under 195.501. A program that exists on paper but has no evaluation dates, no task lists, and no evidence per individual fails the rule. The gap shows up the same way everywhere: the roster has names, the file has no assessments, and a contractor crew rotated in without ever being evaluated.
OQ sits beside the other credential stacks an oilfield contractor carries: COI and prequalification, driver qualification files, and incident investigation. If evaluations and their dates live in a binder that gets assembled for the inspection, an operations audit will show which workers are qualified on paper and which are qualified on evidence.
