Section V-30575 - Which facilities must I electrically isolate and what inspections, tests, and safeguards are required? [49 CFR 195.575]

A. You must electrically isolate each buried or submerged pipeline from other metallic structures, unless you electrically interconnect and cathodically protect the pipeline and the other structures as a single unit. [ 49 CFR 195.575(a)]

B. You must install one or more insulating devices where electrical isolation of a portion of a pipeline is necessary to facilitate the application of corrosion control. [ 49 CFR 195.575(b)]

C. You must inspect and electrically test each electrical isolation to assure the isolation is adequate. [ 49 CFR 195.575(c)]

D. If you install an insulating device in an area where a combustible atmosphere is reasonable to foresee, you must take precautions to prevent arcing. [ 49 CFR 195.575(d)]

E. If a pipeline is in close proximity to electrical transmission tower footings, ground cables, or counterpoise, or in other areas where it is reasonable to foresee fault currents or an unusual risk of lightning, you must protect the pipeline against damage from fault currents or lightning and take protective measures at insulating devices. [ 49 CFR 195.575(e)]
