Southern California Gas did not extend a high-linepack OFO beyond Saturday.

Citing scheduled maintenance and warmer market-area forecasts this week, Tennessee said an Imbalance Warning will become effective Tuesday in Zones 5 and 6. It requires all delivery point operators in those zones to keep actual daily takes out of the system equal to or less than scheduled quantities regardless of their cumulative imbalance position. All receipt point operators are required to keep actual daily receipts into the system equal to or greater than scheduled quantities regardless of their cumulative imbalance position, Tennessee said.

In addition, affiliated Spectra Energy pipelines Texas Eastern, Algonquin and Maritimes & Northeast said they were requiring shippers in their Northeast market area to either stay on rate or run positive imbalances starting Tuesday until further notice.

Northwest reported that the control upgrade project at the Jackson Prairie storage facility, which was scheduled for June 1-7 and prevented injections or withdrawals, had been completed to the extent that injections and withdrawals were being allowed again for Monday’s gas day.

Rockies Express (REX) declared a force majeure effective Sunday until further notice due to mechanical issues on Unit #2 at Steele City Compressor Station. Following an assessment of the damage, REX said it has determined that repairs will not be completed until at least Sunday. During the work, quantities through Segment 260 will be limited to 1,500,000 Dth/d, the pipeline said, and AOR/IT, secondary and primary FT nominations are at risk of not being fully scheduled. REX reminded shippers that emergency shutdown tests and maintenance projects are still scheduled for Tuesday at the Julesburg, Blue Mound, Arlington and Wamsutter compressor stations, along with a smart pig run from Bertrand to Steele City. During this outage, capacity through Segment 130 will be limited to 1,550,000 Dth/d; capacity through Segment 140 will be limited to 1,650,000 Dth/d; and capacity through Segment 200 will be limited to 1,400 MDth/d, putting AOR/IT, secondary and primary FT quantities at risk of not being fully scheduled.

Questar said it has completed the repairs necessary to get Thistle Compressor Station running again and raised ML 104 segment capacity to 520,000 Dth/d Monday. “Shippers should note that a shutdown for permanent repairs will be needed in the future,” Questar added.
