Transportation Notes

Pacific Gas & Electric is lifting Friday a systemwide high-inventory OFO that had been implemented Wednesday.

Northwest notified customers of a Declared Deficiency Period at the Pleasant View Compressor Station that took effect Thursday and was expected to last no longer than five days. "While reviewing the data acquired from the recent south end pig runs, a mainline anomaly requiring immediate repair was identified near the Mapco-Delores delivery point" just south of Pleasant View, Northwest said. It was required to lower the operating pressure in the affected segment to 80% of normal, which cut mainline capacity to 275,000 Dth/d. Since primary nominations through the station were already scheduled above the design capacity of 352,446 Dth/d, this reduction resulted in a daily deficiency volume of 77,446 Dth/d, the pipeline said.

Noting that in July it had restricted backhaul nominations on the Mobile Bay Lateral until further notice (see Daily GPI, July 21), Transco said Thursday it has seen a return of Mobile Bay deliveries to the mainline. Effective Friday Transco will again allow backhaul nominations for gas received on its mainline for delivery to Mobile Bay Lateral locations. The pipeline said it will continue to closely monitor lateral receipts and deliveries to ensure that "the lateral operates within acceptable parameters," adding a caution to shippers that it may need to disallow backhauls again at some point in the future.

Kern River said favorable operating conditions allowed it to increase Veyo Station capacity to 2,025,000 Dth/d Thursday and a further boost to 2,030,000 Dth/d will take effect Friday until further notice.

Gulf South will begin about three weeks of scheduled maintenance on Bistineau Compressor Station Unit #3 on Nov. 27. Injection capacity into the Bistineau Storage Field in North Louisiana will be reduced by 75 MMcf/d during this work, but withdrawal capacity should not be affected, Gulf South said. The pipeline also reported having begun unscheduled maintenance Wednesday on Unit #2 at the Hall Summit Compressor Station. Until further notice Hall Summit capacity could be affected by as much as 75 MMcf/d, it said.
