The FS1 event occurred June 12 during plant restart operations. Flaring occurred until sufficient gas was brought into the plant to load up the compressors. Flaring occurred from 20:00 to 22:06 (126 minutes), total volume flared was 3499 MSCF. GC1 flared from 20:19 to 22:30 (131 minutes) on June 11. The flaring occurred when the Annex shut down due to a C -bank level transmitter failure. Total volume flared was 1365 MSCF. On June 11 GC2 flared for 18 minutes. However, the flared volume exceeded 5000 MSCF. This event occurred when both LPS turbine /compressors tripped to minimum during a process automation upset. The machines had to be manually reloaded to end the flaring event. Total volume flared was 6875 MSCF. If you require additional information, please don't hesitate to call me.

Intermittent flaring occurred during the troubleshooting and restart process. Flaring ended when sufficient production was brought on to generate enough LP gas to enable the LP compressor to remain loaded.

Flaring in excess of 5,000 MSCF occurred at CGF, FS1, GC1, GC2 and GC3 when CCP unexpectedly shut down two high stage compressors while "de- mobilizing" obsolete, turbine, control panels. During the de- mobilization process an incorrect wire was lifted, resulting in an ESD of two of the four high stage compressors. GPB shut in 2 MMMSCF /d of production to get out of flare. The following volumes were flared at each plant during the event: CGF 8,400; FS1 12,865; GC1 6,475; GC2 4,167; and GC3 6,771 (all volumes MSCF) .

Two extended flaring events occurred at FS1 on 10/1 and 10/2 for planned maintenance on their LPS machines. On 10/1 LPS machine 1803 was shut down for water washing. Total duration was 20 hours and 19 minutes, total volume was 4,385 MSCF. The second event occurred on 10/2, for the same activity on 1804. Total duration was 14 hours and 28 minutes, total volume was 1,293 MSCF. FS2 water washed their LPS machine (1803) on 10/4. Total flare duration was 4 hours and 26 minutes, total volume was 924 MSCF. On 10/5, GC1 had two extended flaring events. The first event took place to de- pressure a flowline to make PSV repairs Total duration was 10 hours and 27 minutes of intermittent flaring which resulted in a total flared volume of 871 MSCF. A second event occurred when ambient temperatures increased. 100 MMSCF /d of production was cut to stop flaring. Total duration of this event was 84 minutes, total volume was 875 MSCF. The LPC facility flared for 97 minutes during the restart process following planned ESD safety system testing on 9/30. Total volume for this event was 97 MSCF. Extended flaring events occurred at GC2 on October 3, 4 and 5 during restart activities following a lengthy, planned, full plant turn- around. Flaring occurred off the LP compressor until sufficient rate was brought on to enable the LP machine to load up and remain loaded (common to all three events). Following the turn - around restart, GC2 was shut down for planned ESD testing, creating an additional extended flaring event. A summary of the flaring events follows: 10/3 Initial restart 21 hrs, 49 min 12,726 MSCF 10/34 Intermittent 22 hrs, 30 min 16,014 MSCF 10/5 Following ESD 8 hrs, 0 min 7,778 MSCF If you require additional information, please don't hesitate to call me.

Dwight Warner GPB Production Optimization TL (907) 659-5566 rage 1 ot 1 An extended flaring event occurred at GC1 on October 21st when CGF had both boosters shut down resulting in high transit line pressure which went to flare. The WOA flared off the annex wet gas flare valve. WOA reduced production rates and shut -in 13 wells (312 mmscfd). Flaring began at 10:25 and ended at 11:16 (51 minutes). Total volume flared was 9846 MSCF. An extended flaring event occurred at GC1 on October 22nd during copus spin cooling on LPS K -7001 compressor for maintenance. Flaring began at 03:18 and ended at 06:04 (166 minutes). Total volume flared was 678 MSCF. An extended flaring event occurred at CGF on October 20th when TIC -1855 shutdown for unplanned maintenance (rub on GG lube oil tine). This caused the stabilizer overhead to go to flare. The flare volume is estimated due to the totalizer not working. A work order has been written for repair. The tandem compressor was fully loaded, process changes were made to reduce flaring while the maintenance was performed. The unit was then repaired, restarted, and loaded. Flaring began at 10:42 and ended at 12:02 (80 minutes). Total volume flared was 2700 MSCF. 1. Facility Number 0290000031 12 Facility Name PBU GC 1 3. Field PBU - W OA 4. Operator BP 5.

A power substation serving CCP went down, causing most of CCP and CGF to shut down. The gas transit line pressured up and all facilities feeding CCP and CGF went to flare (LPC was not affected). After being restored, the substation went down again. Here is a breakdown of flare volumes for each facility. Duration is total duration over both substation failures.

CCP substation was washed that day. followed by CGF and the seawater plants. All substations are in the process of being washed again after the recent windstorm caused dirtying of the insulators from flying dirt/dust/gravel (not enough snow cover).

The large dirt/contamination caused flashover that damagaed the CPS yard step -up transformer T -6 and caused the severe voltage sags and surges to go throughout the entire GPB power grid and shutdown numerous pieces of equipment at some of the facilities causing flaring. Shown below are the totals for each facility and the longest duration of any flaring event due to the outage at the respective facility.

A substation at CCP /CGF surged /shorted which caused CGF to loose all power and the FS1 annex to shut down. This also resulted in flaring at some of the other facilities.
