Subject:  Plymouth LNG Storage Unplanned Maintenance

Notice Text:

Northwest Pipeline (Northwest) is currently performing

unplanned maintenance on its liquefiers at the Plymouth

LNG Storage Facility (Plymouth). During the Liquefaction

Period, Northwest has experienced intermittent shutdowns

of both liquefiers significantly impacting its ability to

liquify gas into LNG for storage ahead of the winter

season. Current tank levels at Plymouth are approximately



Northwest has been able to successfully return to service

one liquefier and is finalizing an estimate on when the

remaining liquefier will resume operations to reach

maximum and continuous liquefaction. Currently, Northwest

plans to liquify during the Vaporization Period and

provide firm peaking service as outlined in the Rate

Schedule LS-2F.


Based on physical limitations of all system storage

facilities, Northwest may have limited ability to accept

imbalance gas that negatively impacts operations as we

approach the heating season. Northwest requests

customers and interconnects to limit banking and manage

current business to flat or a slight draft. Northwest

continues to monitor pipeline conditions and will provide

updates as warranted.
