Subject:  Update - Chehalis Outage ISD

Notice Text:

As referenced in Notice ID# 25-112, Northwest is experiencing&nbsp;<br />additional unplanned maintenance at the Chehalis Compressor&nbsp;<br />Station. The current available capacity is 600,000 Dth/day&nbsp;<br />southbound. The in-service date is now expected to be gas day&nbsp;<br />August 22, 2025.&nbsp;<br /><br />Northwest apologizes for the prolonged disruption at the&nbsp;<br />Chehalis Compressor Station. Although the previously completed&nbsp;<br />work was done successfully and safely, it is not unexpected to&nbsp;<br />experience some residual attention and recalibration in&nbsp;<br />adjacent areas as Unit 1 exercises high amounts of run time.&nbsp;<br />Northwest&rsquo;s operational and commercial priority is to bring&nbsp;<br />Chehalis back to full and consistent throughputs for an&nbsp;<br />uninterrupted remainder of the year.<br /><br />Northwest will continue to mitigate Operational Flow Orders&nbsp;<br />(OFO) and deficiency impacts at the Chehalis compressor station&nbsp;<br />on an operationally available basis, as referenced in Notice ID&nbsp;<br />25-112. Any changes or updates to the schedule will be promptly&nbsp;<br />communicated via the Northwest Pipeline Portal.&nbsp;&nbsp;<br /><br />Please reference the Maintenance Schedule tab at&nbsp;<br />www.northwest.williams.com for more information.<br /><br /><br />If you have any questions, please contact your Commercial&nbsp;<br />Services Representative or the hotline at 713-215-6301.<br />
