Pacific Gas and Electric issued a systemwide Stage 2 low-inventory order on its California Gas Transmission system for Friday, setting penalties of $1/Dth for exceeding a 5% tolerance on negative daily imbalances.

Citing mild weather forecasts and limited operational flexibility, Iroquois declared a systemwide Imbalance Warning for Thursday through next Tuesday, requiring all delivery point operators to keep actual daily takes out of the system equal to or greater than scheduled quantities. No unscheduled Operational Balancing Agreement paybacks of due-pipe imbalances will be allowed, Iroquois said.

A recent smart pig run on Columbia Gulf‘s East Lateral revealed an anomaly on Line 300 east of Centerville, LA. Eleven meters were shut in Thursday until the pipe remediation work is completed, which is anticipated to take five days. At this time firm transportation service is not expected to be impacted, Columbia Gulf said.

The Acadian Pipeline interconnect with Southern has been shut in due to a gas quality issue. Southern said it was taking nominations at the point to zero effective with the Evening Cycle for Thursday’s gas day until further notice. Southern also reported that it developed a repair plan and is acquiring replacement parts for an unscheduled engine outage at Selma Compressor Station on the South Main Line in south-central Alabama. Based on its best information available, the pipeline expects to return the engine to service no sooner than Jan. 6. No impact to firm or interruptible service is anticipated through the New Year’s Day holiday, but some reduction in available interruptible transportation could occur until the repair is complete.

Tennessee said Thursday it is investigating a report of a possible leak on Line 524J-100 offshore Louisiana. Six meters have been required to shut in during the investigation, but Tennessee will allow their nominations to remain in place for the time being. Tennessee also said it had completed repairing Unit 1A at Station 323 and returned it to service, allowing the associated force majeure to be lifted.

Northwest said northbound primary nominations through Roosevelt Compressor Station in the Timely cycle for Thursday’s gas day were approximately 586,000 Dth/d, exceeding the current operational capacity of 562,000 Dth/d. To ensure operational integrity over the holiday weekend, Northwest is issuing a Recall Advisory and declaring an OFO at the station effective Friday until further notice. Under the recall advisory, Northwest asks shippers to recall capacity that is subject to OFO recall provisions. If scheduled quantities for Friday continue to exceed the operational capacity at Roosevelt, Northwest will provide shippers with their specific OFO obligations.
