Citing increased throughput that would result from completion of Pocatello (ID) Compressor Station maintenance Wednesday and the recent levels of northbound primary firm nominations through Kemmerer (WY) Compressor Station, Northwest said it will lift Thursday a Recall Advisory and OFO at Kemmerer. The OFO was issued Dec. 1 in order to reduce primary firm nominations to the operational capacity of 675,000 Dth/d. Because of colder temperatures and other factors, Northwest said, current operational capacity of Kemmerer is approximately 700,000 Dth/d, and customers should keep in mind that for the upcoming holiday week primary firm nominations in excess of 700,000 Dth/d at Kemmerer could result in the declaration of another OFO.
Texas Eastern reported completing repairs on a unit and returning it to service at the Bernville (PA) Compressor Station (see Daily GPI, Dec. 15), and it said limited capacity became available Tuesday for gas sourced upstream of Bernville/Marietta for downstream delivery. In addition, limited capacity was available Wednesday for gas sourced upstream of Bernville/Eagle for downstream delivery, the pipeline said. Due to a continuing outage at the Entriken (PA) Compressor Station, it estimated experiencing a capacity reduction of approximately 65,000 Dth/d through and downstream of Entriken. Texas Eastern also reminded customers that it continues to experience high demand on the system and thus requires them to either stay in balance or run a positive imbalance.
