Taking the rare step of issuing an OFO on the morning of its implementation, Southern California Gas (SoCalGas) declared a high-linepack OFO on the Intraday 1 nominations cycle for Wednesday. The giant LDC said it would assess Buy-Back charges in accordance with its rules and tariffs to customers who delivered more than 110% of their actual gas usage on the OFO day. The OFO was extended with the same conditions through Thursday.

Southern Natural Gas said a dive boat had confirmed a leak in its 14-inch diameter Main Pass 107 line offshore Louisiana upstream of the Toca Compressor Station (see Daily GPI, May 2). A repair plan has been developed and approved, Southern said, and based on the available information it anticipated the line returning to service sometime Sunday. “However, current weather forecasts indicate inclement weather in the area Wednesday through Friday and this could impact the in-service date,” the pipeline added.

Recent changes on the West Leg of Northern Natural Gas at the Minneapolis #1P Town Border Station have resulted in a change in flow, the pipeline said. Gas can no longer flow from the West Leg northward onto the Willmar branchline. As a result, all delivery points on the West Leg between the Iowa/Minnesota state line and Minneapolis #1P “will no longer be subject to Oakland or Ogden allocations, since gas originating from Demarc/Trailblazer/REX to these points avoids these constraints.” However, this configuration change also means that any gas received at the Welcome point for delivery to points downstream of the Oakland and Ogden constraints will be included in these allocations, because this gas must pass through the constraints, Northern said, adding, “These changes will be implemented in the near future and will be conveyed in a posting as the date is determined.”
