The intermittent event lasted for 1440 minutes. Flaring was due to suspected leaking flare valve or PSV associated with the GLT system or other plant system. Flaring continued into the following day as operations staff investigated the cause of the flaring event. A flaring event occurred at GC1 starting at 02/06/2013 00:00 and stopping at 02/06/2013 24:00 with a volume of 960 (MSCF). The intermittent event lasted for 1440 minutes. Flaring was due to suspected leaking flare valve or PSV associated with the GILT system or other plant system. Flaring continued into the following day as operations staff investigated the cause of the flaring event. A flaring event occurred at GCI starting at 02/08/2013 00:00 and stopping at 02/08/2013 24:00 with a volume of 3700 (MSCF). The intermittent event lasted for 1440 minutes. Flaring was due to suspected leaking flare valve or PSV associated with the GLT system or other plant system. Flaring continued into the following day as operations staff investigated the cause of the flaring event. A flaring event occurred at GC1 starting at 02/10/2013 00:00 and stopping at 02/10/2013 24:00 with a volume of 4166 (MSCF). The intermittent event lasted for 1440 minutes.

A flaring event occurred at GC1 starting at 02/11/2013 00:00 and stopping at 02/11/2013 24:00 with a volume of 4970 (MSCF). The intermittent event lasted for 1440 minutes. Flaring was due to suspected leaking flare valve or PSV associated with the GLT system or other plant system. Flaring continued into the following day as operations staff investigated the cause of the flaring event. A flaring event occurred at GC1 starting at 02/21/2013 00:01 and stopping at 02/21/2013 06:23 with a volume of 6980 (MSCF). The event lasted for 382 minutes. Flaring was due to a failed power supply on the OT -28 (oil transit line) PLC which caused the shutdown of oil shipping pumps and associated production banks. Flaring continued while the power supply was replaced, production banks were restarted and flare valves went closed one plant stabilized. A flaring event occurred at GC1 starting at 02/25/2013 00:00 and stopping at 02/25/2013 24:00 with a volume of 2539 (MSCF). The intermittent event lasted for 1440 minutes.

Flaring was due to suspected leaking flare valve or PSV associated with the GLT system or other plant system. Flaring continued into the following day as operations staff investigated the cause of the flaring event. A flaring event occurred at GC1 starting at 02/27/2013 00:00 and stopping at 02/27/2013 24:00 with a volume of 4330 (MSCF). The intermittent event lasted for 1440 minutes. Flaring was due to suspected leaking flare valve or PSV associated with the GLT system or other plant system. Flaring continued into the following day as operations staff investigated the cause of the flaring event. A flaring event occurred at GC1 starting at 02/28/2013 00:00 and stopping at 02/28/2013 24:00 with a volume of 4020 (MSCF). The intermittent event lasted for 1440 minutes. Flaring was due to suspected leaking flare valve or PSV associated with the GLT system or other plant system.

A flaring event occurred at GC1 starting at 05/22/2013 16:45 and stopping at 05/23/2013 with a volume of 320 (MSCF). The event lasted for 435 minutes and was due to the skid50 valve closure which shut down the GC1 shipping pumps. Flaring occurred to maintain compressor operation, and stopped when flow rates were re-established to the GC. A flaring event occurred at CGF starting at 05/29/2013 15:35 and stopping at 05/29/2013 17:00 with a volume of 16847 (MSCF). The event lasted for 85 minutes. The event had a volume greater than 5000 (MSCF) and was due to shutdown of 1805 T/C due to PCU glitch. A flaring event occurred at CGF starting at 05129/2013 08:40 and stopping at 05/29/2013 11:00 with a volume of 16847 (MSCF). The event lasted for 140 minutes. The event had a volume greater than 5000 (MSCF) and was due to a shutdown of 1855 T/C — flaring occurred while operations/maintenance worked to get the machine back online. A flaring event occurred at FS3 starting at 05/29/2013 01:45 and stopping at 05/29/2013 03:55 with a volume of 875 (MSCF). The event lasted for 130 minutes and was due to 1806 T/C cooldown for planned maintenance. Flaring stopped when cooldown was completed. A flaring event occurred at FS1 starting at 05/26/2013 16:30 and stopping at 05/26/2013 16:31 with a volume of 83 (MSCF). The event was a black smoke event. Another event occurred at FS1 starting at 05/26/2013 16:11 and stopping at 05/26/2013 16:13 with a volume of 168 (MSCF). The event was a black smoke event. A third event occurred at FS1 starting at 05/26/2013 15:51 and stopping at 05/26/2013 16:00 with a volume of 755 (MSCF). The event was a black smoke event. These events were all related to the 1803 T/C water wash gas crank sequence, including attempts at the crank sequence to investigate flare issues. Please let me know if you have any questions.

The intermittent event lasted for 1440 minutes. Flaring was due low rates at GC1 during TAPS proration resulting in intermittent flaring from the LP and IP systems. Flaring ended as rates were increased after proration was over allowing the LP/IP systems to remain loaded. A flaring event occurred at GC1 starting at 06/11/2013 00:00 and stopping at 06/11/2013 24:00 with a volume of 40 (MSCF). The intermittent event lasted for 1440 minutes. Flaring was due to flaring during startup of a GILT compressor, starting turbine exhausts to flare system. Flaring ended when GLT startup was complete. Note: Suspect duration is over- stated — however this is how event was reported. A flaring event occurred at GC1 starting at 06/14/2013 10:15 and stopping at 06/14/2013 13:20 with a volume of 2030 (MSCF). The intermittent event lasted for 185 minutes. Flaring was due to flaring off of V-136 and HP 1st Stage Separators due to high gas transit line pressure at GC1 resulting from a compressor shutdown at CGF. Flaring continued while unit at CGF was restarted and transit gas pressure returned to normal operating range, at which time flare valves closed. A flaring event occurred at GC1 starting at 06/22/2013 13:25 and stopping at 06/22/2013 16:57 with a volume of 130 (MSCF). The intermittent event lasted for 212 minutes. Flaring was due to shutdown testing on GC1 Slug Catchers. Flaring continued during testing. Flaring ended when testing was completed and flare valves closed.

The event had a volume greater than 5000 (MSCF). Approximately 1/3 of the GC1 facility (LPS, WSW, & PWX) lost all power simultaneously. The loss of power resulted in the gas compressor cooling fans (gas/utility water), and instrument air going down. Soon after this occurred the LIPS and GILT compressors were shutdown in a controlled fashion by the board operator. The loss of these compressors resulted in a flaring event. A flaring event occurred at GC1 starting at 10/19/2013 00:00 and stopping at 10/19/2013 14:30 with a volume of 3022 (MSCF). The event lasted for 870 minutes and was due to.

Flaring was due to flaring off of C Bank Slug Catcher during the de -pressuring of the Y Pad GLT supply line, via the Y Pad LDF. The GLT supply line was de -pressured as a precautionary measure, while the LDF is down for repairs. Flaring ended when the GLT supply line was sufficiently de -pressured.
