Southern California Gas declared a high-linepack OFO for Friday, saying it will assess Buy-Back charges in accordance with its tariffs to customers who deliver into its system more than 110% of their actual gas usage on the OFO day.

Northwest implemented a Declared Deficiency Period at the Burley Compressor Station. The pipeline said it had completed inspection work at its Buhl Compressor Station ahead of schedule, and as a result it started Burley inspection work Wednesday, a day earlier than originally planned. Available capacity through Burley during its outage was reduced from the design capacity of 593,000 Dth/d to 469,000 Dth/d, resulting in a daily deficiency volume of 124,000 Dth/d, Northwest said. Primary nominations through this corridor exceeded available capacity, necessitating the Declared Deficiency Period. However, due to the early start of the inspection work, the deficiency period was expected to last one day and end sometime Thursday. Further, based on the early completion of the annual inspections at Buhl and Burley, Northwest has reduced the anticipated two-day outage for the Lava Hot Springs Compressor Station inspection, originally scheduled for May 29-30, to one day (May 30). The available capacity during this outage is estimated to be 578,000 Dth/d.

Texas Eastern said it was required to force balance all long-imbalance TABS-1 (Transportation Aggregation and Balancing Services) pools for Friday in its South Texas and East Texas zones and on the M1 24-inch diameter line.

ANR said Thursday it will continue with unplanned engine repairs at Sardis (MS) Compressor Station along the Southeast Mainline (SEML). The work is reducing total SEML capacity by 250 MMcf/d (leaving 1,055 MMcf/d available) through May 29. Based on current nominations, ANR expects that the reduction will result in the curtailment of interruptible services. ANR also reported completing engine repairs at Havensville (KS) Compressor Station and lifted associated capacity restrictions through the Southwest Mainline.

Wyoming Interstate Co. will be pigging the Wyoming mainline from Wamsutter Station to Harold Burrow Station on two days next month. The pigging operations will reduce capacity through Harold Burrow from 770 MMcf/d to 375 MMcf/d on June 5 and to 350 MMcf/d on June 11.
