Wis. Admin. Code Public Service Commission § PSC 135.206 - Addition [49 CFR 192.206w]

Current through March 28, 2022

After 49 CFR 192.205, insert:

192.206w Pipelines on private right-of-way of electric transmission lines. Where gas pipelines parallel overhead electric transmission lines on the same right-of-way, the company operating the pipelines shall:

(a) Employ blow-down connections and relief valve vents that will direct the gas away from the electric conductors.
(b) Make a study in collaboration with the electric company on the common problems of corrosion and electrolysis, taking the following factors into consideration:
(1) The possibility of the pipeline carrying either unbalanced line currents or fault currents.
(2) The possibility of lightning or fault currents inducing voltages sufficient to puncture pipe coatings or pipe.
(3) Cathodic protection of the pipeline, including location of ground beds, especially if the electric line is carried on steel towers.
(4) Bonding connections between the pipeline and either the steel tower footings or the buried ground facilities or the ground-wire of the overhead electric system.
(c) Investigate the necessity of protecting insulating joints in the pipeline against induced voltages or currents resulting from lightning strikes. The protection can be obtained by connecting buried sacrificial anodes to the pipe near the insulating joints or by bridging the pipeline insulator with a spark-gap or by other effective means.
