49 CFR 195.9
Outer continental shelf pipelines.
Operators of transportation pipelines on the Outer Continental Shelf must identify on all their respective pipelines the specific points at which operating responsibility transfers to a producing operator. For those instances in which the transfer points are not identifiable by a durable marking, each operator will have until September 15, 1998, to identify the transfer points. If it is not practicable to mark durably a transfer point and the transfer point is located above water, the operator must depict the transfer point on a schematic maintained near the transfer point. If a transfer point is located subsea, the operator must identify the transfer point on a schematic which must be maintained at the nearest upstream facility and provided to PHMSA upon request. For those cases in which adjoining operators have not agreed on a transfer point by September 15, 1998, the Regional Director and the Bureau of Ocean Energy Management, Regulation and Enforcement Regional Supervisor will make a joint determination of the transfer point.#
