... the station(s) of the appropriate course of action. For example, excessive discharge pressure at Station A might prompt Gas Dispatch to request Station B to boost discharge pressure resulting in a lower suction pressure at Station A. This, in turn, results in a lower discharge pressure at Station A. Gas...
