This notice is intended to resolve conflicting information received as the result of Notice 1, Docket No. PS-53, that proposed to require the installation of remotely controlled valves at 7.5 mile intervals on pipelines transportating highly volatile liquids (HVL). This nQtice proposes alternative courses of regulatory action that would require remotely controlled valves on HVL pipelines at pump stations and terminals or at intervals spaced in accordance with a class location concept similar to that in 49 CFR. Part 192 for gas transmission pipelines.
