It started on 02/18/2015 and continued through 02/21/15. Maintenance applied additional pressure to the actuator to seat the valve which temporarily stopped the leaking until the valve could be isolated and rebuilt on 3/2. Upon teardown of the valve, it was noted the cage was fine but the seats and plug needed replacement negating the need to wait 3 months for a cage replacement. The valve has been repaired and the flaring has ceased. 02/18/2015 00:01 and stopping at 02/18/2015 23:59 with a volume of 622 (MSCF).
