Citing low linepack, Transwestern issued an Alert Day for the West of Thoreau area for Tuesday's gas day. Transwestern said it was utilizing an Alert Day rather than an OFO because the low linepack is not attributable to performance of particular receipt or delivery points. Transwestern said it hopes that the lowpack conditions will subside enough to allow the Alert Day to be canceled, but meanwhile operators should plan for this operating provision to be in effect for the entire gas day.

Southwest Gas issued a Hold Burn to Scheduled Quantities notice Friday due to low linepack on upstream Kern River Gas Transmission. Southwest also said negative daily nominations for imbalance paybacks from Southwest to customers were eliminated for Friday's gas day. On Monday, with low linepack continuing on Kern River, the Las Vegas-based LDC said it would implement Tuesday a Stage 3 OFO, but the OFO will end Wednesday morning.

Maritimes & Northeast U.S. (M&N) said over the holiday weekend it had been advised that a previously planned outage of the Sable Offshore Energy Project has been delayed. The revised schedule called for a partial-day outage Monday (Nov. 29) followed by a complete one Tuesday and another partial-day outage Wednesday. Full Sable operation will return for Thursday's gas day, M&N said. No supply will be available from Sable to flow on the M&N system during all three outage days, the pipeline said, and shippers sourcing gas from Sable should make appropriate arrangements. See the bulletin board for more information.
