Regulations: during and after rehabilitation

Corrosion control

Corrosion control falls into the same category as welding, in that any
coating activity would have to meet the applicable regulation. This would
include coating material specification, cleaning and preparing the pipe
surface, test stations and leads, monitoring and corrosion-control records.

Operations

The operations' requirements cover a broad range of subjects that are
essential to the safe operation of any pipeline. These include written operat-
ing procedures for normal operations and maintenance, emergency plans and
procedures, training requirements, establishment of MAOP (maximum allow-
able operating pressure), and maps and records. Because rehab work is
maintenance, the O&M procedures must also cover this work.
This section of the regulations is the only time that an operator writes his
own regulations. The basic regulatory requirement is that he prepare a
written plan, and then that he follows it. The operator has the responsibility
of developing requirements adequate for the safe operation of his particular
system.
We might also note that an operator cannot delegate or contract away this
responsibility. He, as the regulated, is always responsible for seeing that these
procedures are met, even if a contractor does the work.

Maintenance

One should also be aware that this also covers a variety of subjects, some
of which may apply to rehab work. These include line markers, valve
maintenance, permanent field repairs of imperfections and damages, maps
and records, and the prevention of accidental ignition.

Accident and safety-related condition reporting

This reporting is required by both the gas and liquid regulations. In many
cases, the lines are worked under pressure and, in the event of an accident,
the accident-reporting requirements would apply. This also applies to the
safety-related condition requirements if the time requirement for corrective
action cannot be met.
