**body:**

Operators shall comply or ensure compliance with the
following requirements for the installation and construction
of new pipeline metallic systems, the relocation or
replacement of existing facilities, and the operation and
maintenance of steel pipelines.
(1) Coatings. All coated pipe used for the transport
of hazardous liquids or carbon dioxide shall be electrically
inspected prior to placement using coating deficiency
(holiday) detectors to check for any faults not observable by
visual examination. The holiday detector shall be operated in
accordance with manufacturer's instructions and at a voltage
level appropriate for the electrical characteristics of the
pipeline system being tested.
(2) Installation. Joints, fittings, and tie-ins shall be
coated with materials compatible with the coatings on the
pipe.
(3) Cathodic protection test stations. Electrical
measurements shall include but are not limited to pipe casing
installations and all foreign metallic cathodically protected
structures. Readings taken at test stations (electrode
locations) over or near one or more anodes shall not, by
themselves, be considered representative.
(A) All test lead wire attachments and bared
test lead wires shall be coated with an electrically insulating
material. Where the pipe is coated, the insulation of the test
lead wire material shall be compatible with the pipe coating
and wire insulation.
(B) Cathodic protection systems shall meet or
exceed the minimum criteria set forth in Criteria For
Cathodic Protection of the most current edition of the
National Association of Corrosion Engineers (NACE)
Standard RP-01-69.
(4) Monitoring and inspection. Each operator shall
utilize right-of-way inspections to determine areas where
interfering currents are suspected. In the course of these
inspections, personnel shall be alert for electrical or physical
conditions which could indicate interference from a
neighboring source. Whenever suspected areas are identified,
the operator shall conduct appropriate electrical tests within
six months to determine the extent of interference and take
appropriate action.
(5) Remedial action. Each operator shall take
prompt remedial action to correct any deficiencies observed
during monitoring.
