maintenance at Jackson Prairie (JP). In May, Puget Sound Energy, the 
operator of the JP storage facility, notified Northwest that 
maintenance will be performed at JP beginning Gas Day July 19, 2021 
through Gas Day July 25. During this time, the facility will be shut-in 
and injections or withdrawals will not be available (netting of 
injection and withdrawal nominations will not be allowed during the 
outage). As a result, the annual maintenance that is usually scheduled 
the first week of October will not be taking place this year.

Additionally, Dominion Energy Questar Pipeline posted its scheduled 
construction and maintenance at Clay Basin. For Gas Day July 13 through 
July 15, Clay Basin will be unavailable for injections and withdrawals.
