Citing customer drafting and receipt point shortfalls, Northwest said it “lost a notable volume from its Jackson Prairie storage account” during Wednesday’s gas day. It also pointed out that Questar‘s Clay Basin storage facility is currently shut in and the forecast for the Pacific Northwest called for cooler temperatures into early this week. “In anticipation of the cooler weather and to ensure the preservation of its Jackson Prairie balancing account, Northwest is providing notice that it may declare customer-specific or system entitlements for overruns for receiving parties located north of the Kemmerer Compressor Station,” the pipeline said. “In addition, Northwest will not tolerate any shortfalls from receipt points south of Kemmerer. If necessary, Northwest will cut nominations in all cycles to match any underdeliveries by upstream interconnects.”

Southern Natural Gas said Friday it is unable to accept nominations at the Main Pass 289 VK receipt point due to a damaged control valve on the meter station. A repair plan is being developed and based on the best available information at this time, the point will not return to service until mid-November, Southern said.

Questar reported that the third-party processing plant it uses to deliver gas to TransColorado at Greasewood had experienced a mechanical failure. Questar cut Greasewood nominations to zero effective with Cycle 3 in Friday’s gas day, but said capacity would return to normal (47,500 Dth/d) in Cycle 1 nominations for Saturday’s gas day. Questar also said it experienced third-party damage to its JL 46 segment near the Altamont Plant, requiring that the plant be shut in last Saturday. Normal service was expected to resume Sunday.

Gallup Station’s C unit will be unavailable until further notice due to unscheduled maintenance, El Paso said Friday. This will reduce San Juan Basin base capacity of 2,840 MMcf/d by 200 MMcf/d, it added.

Kern River said Friday it had replaced the Elberta Compressor Station’s gas turbine (see Daily GPI, Oct. 18) and put the unit in service, allowing an increase of operational capacity at Veyo Compressor Station to 2,025,000 Dth/d.

In conjunction with Oct. 22-23 maintenance between the Baileyville and Richmond compressor stations and a reduction of flows through Richmond to zero during this work (see Daily GPI, Oct. 19), Maritimes & Northeast U.S. said that as of last Saturday until further notice, it is not allowing any due-shipper imbalance payback nominations or due-pipe imbalance creation.

ANR began unplanned engine maintenance Friday at St. John (IN) Compressor Station, reducing total St. John west-to-east capacity by 140 MMcf/d (leaving 1,165 MMcf/d available) through Monday (Oct. 22). Based on current nominations along the Michigan Legs, it is anticipated that the reduction may result in curtailment of IT and Firm Secondary nominations, ANR said.

Tennessee said it had completed replacement of Main Line Valve (MLV) 851 and of pipe at Highway 15 between MLVs 851-1 and 852-1 Friday, ending related restrictions on the 800 Line.
