Northwest reminded customers that the operator of the Jackson Prairie storage facility on its system will be conducting an annual bottom-hole pressure test Monday through Friday of next week, during which no injections or withdrawals will be available. Northwest said it will begin accepting withdrawal nominations for the Oct. 6 gas day, and injection nominations “will be accepted as space becomes available in the facility. In order for Northwest to maintain its storage account balance, it is critical that customers do not draft the system on the days leading up to the test.” The pipeline asked that customers stay on rate during the outage as it “will have very limited operational flexibility due to the Jackson Prairie test and the anomaly work being performed between the Muddy Creek and Kemmerer compressor stations.”

Cheyenne Plains Gas Pipeline reported having sufficient information from its damage assessment at Cheyenne Plains Compressor Station (see Daily GPI, Sept. 18) to develop a plan for restoration of the facilities. Its best estimate for resuming full service on the Cheyenne Plains system is mid-November. “We believe the current critical path to service restoration is replacing the cables, wiring and fiber optics necessary to restore power and to operate the facilities once they are back in service,” the pipeline said. “Accordingly, we have arranged for contractors to work around the clock on these tasks. There is other work that is currently less time-intensive, but essential before we can return to full service. This includes removing, replacing and/or restoring certain air systems both in the yard and in the amine processing plant. In addition, certain yard piping and valves, including those involved in the main gas piping, will have to be removed and replaced as well. Some foundations will need to be repaired.” See the bulletin board for further details.

Florida Gas Transmission (FGT) plans to upgrade valves next Thursday 4 at Compressor Station 6 in Zone 1. FGT will schedule up to approximately 200,000 MMBtu/d through the station that day; during normal operations it schedules up to 300,000 MMBtu/d there. It extended an Overage Alert Day implemented Wednesday through at least Thursday.

Gulf South will begin installation of a new operational platform and piping at Eugene Island 51 offshore Louisiana Sunday. The project, which was originally scheduled to begin Aug. 21 but has been delayed several times by uncertainty about offshore weather, is expected to last up to 24 days depending on weather conditions, Gulf South said. It added an eleventh receipt point to 10 listed in the original posting as being required to shut in during the work.

TGT declared an OFO in connection with its mandate earlier this month that all Interruptible Storage Service (ISS) customers must remove their ISS volumes from the pipeline’s storage fields by Oct. 31 (see Daily GPI, Sept. 10). The OFO provides that shippers who do not meet the 100% withdrawal requirement will have any remaining ISS gas become the property of TGT at no cost to the pipeline. In addition, each MMBtu remaining in an ISS customer’s storage account after the deadline will be subject to a penalty “equal to the greater of $50/MMBtu or three times the Highest Average Weekly Price during October” as determined by the pipeline’s tariff. TGT also said it will shut in the Bicknell #2 meter on the Slaughters Montezuma system Monday and Tuesday to accommodate the moving of coal mining equipment across the pipeline’s right-of-way in Knox County, IN.

Trunkline will not accept any nominations at the ANR Patterson meter in South Louisiana during an Oct. 9-10 outage at the location for inspection of meter tubes. The same restriction will be in effect for an Oct. 10-11 outage of the LIG Patterson meter, which is also for inspection of meter tubes.

As part of its Southern System expansion work, Questar will make modifications at Oak Spring Compressor Station Oct. 9-12. To facilitate the work, capacity in Questar’s ML 104 segment will be reduced to 270,000 Dth/d Oct. 9-10 and then to zero Oct. 11-12. ML 104 capacity will return to 380,000 Dth/d Oct. 13.

Transco has scheduled Oct. 4-5 facility modifications associated with a mainline tap installation for the DCP Midstream Meter Station at Mile Post (MP) 71.92 in Brooks County, TX. The tap location is in a single-line section of the mainline, so 11 receipt points upstream of MP 64.65 must be shut in during the work. About 55 MMcf/d will be affected, Transco said, and the Tetco (Texas Eastern) Lacy delivery meter will not be available during this outage due to incompatible operating pressures between the two pipes.

The Alberta BC Meter Station will be undergoing modifications Oct. 1-7, NOVA said, which will limit Alberta/BC (British Columbia) border delivery capability to 2,577 MMcf/d, assuming all facilities are available. There is the potential of an IT delivery restriction during this period, NOVA said.
