Group Total: 26,622 Report NSTR Flare report 08-04 FINAL.xls 6 of 6 RE: August Gas Disposition 1) Milne Point installed a new, vertical flare in late August_ This flare uses air for assist gas instead of fuel gas so you'll see the assist gas go to zero in the Sept report_ Pilot purge IS slightly higher with the new flare and I'm tracking down the technical reason for that_ 2) I talked with the Operations Lead Tech at Endicott regarding this flaring. He said they were depressuring and deinventorying the facility over the 14th and 15th. The volumes shown were flared volumes, not assist gas. The comment refers to the need to use some assist gas to prevent black smoke during this time. 3) I've requested this programming change for the Northstar report. Let me know if you need more information.

Jim Regg wants to know is 100% of this assist gas, 1285 mcf? *Northstar *- Something has to be corrected for this facility reports. They are still the most confusing reports to review_ All future reports must be sorted by date and time. It might take some revisions to your reports, how they sort or how they are automated. Too much time is spent trying to follow what is going on. The events greater than 1 hour must be listed by *date and time*. They must include duration of event, mcf gas flared, incident description and remediation.

The DGVs provide head balancing between the stages of the compressor_ If one fails, we get vibration shutdowns as the stages become unevenly balanced_ In this instance, one of the DGV positioners, the device used to move the DGVs, failed with the DGV in the closed position. This is the normal start position so that on subsequent start tries, the failure went unnoticed with only A high vibration shutdown alarm taking the unit down. The repeated start attempts are what gave us the extended flare events. When we figured out the problem, we replaced the positioner, added deviation alarms between DGV demand and actual position and the machine was returned to service. Give me a call if you need more detail_ Thanks Steve Carboy Northstar OTL 670-3601 -----Original Message----- From: James Regg [mailto:jim regg@admin.state.ak.us] Sent: Friday, October 15, 2004 10:44 AM To: PBU, Nstar Ops Team Leader Subject: Northstar Flaring - August Reports August 2004 gas disposition report showed a volume increase in > Ihr events; it appears from summary pages attached to the report that a significant part was attributed to the LP compressor being down "because of diffuser guide vane problems"_ I'd appreciate a brief explanation of the DGV and the specific problems encountered.
