LAC 43:XI.4555. Valves: Location (Formerly §1555)

A. A valve must be installed at each of the following locations: 1. on the suction end and the discharge end of a compressor station in a manner that permits isolation of the station equipment in the event of an emergency; 2. on each mainline at locations along the pipeline system that will minimize damage from accidental carbon dioxide discharge, as appropriate for the terrain in open country, for offshore areas, or for populated areas; 3. on each lateral takeoff from a trunk line in a manner that permits shutting off the lateral without interrupting the flow in the trunk line; 4. on each side of a reservoir holding water for human consumption.
