Due to an imbalance on upstream pipelines and requests for drafting gas that has been banked over the last several days, Southwest Gas issued a Hold Burn to Scheduled Quantities notice Wednesday. Southwest asked shippers “to ensure that actual takes meet or exceed scheduled supplies, which will assist in clearing the positive imbalance that has been created on the upstream pipelines. Also, positive daily nominations for imbalance paybacks from customers to Southwest have been eliminated” effective Wednesday until further notice. If current conditions persist, Southwest said, it may be required to issue an OFO.

Citing seasonal operating conditions, Questar reduced capacities at its Clay Basin Storage facility Wednesday to 300,000 Dth/d for current daily injections and 25,000 Dth/d for Park and Loan injection service, for a total daily injection capability of 325,000 Dth/d. Questar also reported experiencing a mechanical failure on the #2 unit at Blind Canyon Compressor Station, which is used with the Oak Spring station to supply Questar’s ML 104 segment. “The compressor bundle will need to be shipped to the vendor for work, which will take approximately one week,” the pipeline said. It reduced ML 104 capacity Tuesday to 460,000 Dth/d until further notice, saying based on Cycle 1 nominations for Wednesday’s gas day, that means about 5,000 Dth/d is being cut.
