Narrative
At 13:51 on 11/30/2013 the station control panel programmable logic controller (plc) failed due to a digital input card failure. The plc failure caused the station to shut down and blow down. The station isolation valves and blowdown valve operated correctly and vented the station main gas piping. At the same time, the fuel gas vent valves opened, but the fuel gas isolation valves, hv-1014 and hv-1036 failed to close. The on-call technician arrived at the station at 16:15 and discovered gas venting through the fuel gas vent valves. At 16:25 the fuel gas vent valves were manually closed. The station was restored to service at 01:15 12/01/2013.
