Citing “insufficient supplies of gas,” CIG notified customers that it anticipates suspending operations at the Natural Buttes Processing Plant starting June 1. The plant “was designed to provide gas conditioning services for a volume of gas that greatly exceeds the current throughput of the facility,” the pipeline said. It also reported receiving notice that effective June 1 a large percentage of current throughput at Natural Buttes will be diverted to the new Chipeta cryogenic processing plant and redelivered to CIG at the Anabuttes receipt point. CIG said it will attempt to continue operating the Natural Buttes plant but expects to suspend that activity “until such time as additional volumes are available for conditioning.” A restart of the plant is estimated to take approximately 24 to 48 hours depending on ambient temperatures, CIG said. While Natural Buttes operations are interrupted, all gas tendered to CIG at that receipt point will be required to meet the pipeline’s mainline gas quality requirements.

Noting that it began an annual inspection Thursday at the Lava Hot Springs Compressor Station, Northwest said primary firm nomination requests through the station exceeded the available capacity of 578,000 Dth/d. Thus it notified shippers of a Declared Deficiency Period for Lava Hot Springs in effect for Thursday and Friday.
