Notice on September 10, 2021

2021 FALL MAINTENANCE 

Annual Fall maintenance for the Mist storage facility is scheduled to take place from October 18 through October 29, 2021. NW Natural does not guarantee it will be able to confirm nomination requests for storage injections and withdrawals during this maintenance period, and service could be interrupted as discussed in Section 7.9 of the Mist Operating Statement.

In order to minimize service disruptions, NW Natural requests customers contact us regarding any plans to utilize Mist storage during this time. Should any service disruption be necessary, firm service requests shall take priority over interruptible service requests.

Thank you for your cooperation and your business. Please continue to monitor this site for updates.

If you have any questions, please contact NW Natural's Gas Supply Department as soon as possible at the email nominations@nwnatural.com
