While bringing production rates up following a total GC S/D, LPS compressors would not load resulting in high S/C pressure and discharging to flare. 2.

Action Taken to Stop Flaring: 1. Flaring was permitted to continue while GC operations personnel attempted find the cause of the problem. A valve was found stuck open and was subsequently closed. 2.
