As posted on the maintenance schedule and communicated in our

annual maintenance call, the Sumas Compressor Station “C” Plant

boiler replacement scheduled from 9/1/2021 through 9/30/2021

has been delayed. This is now estimated to occur from 10/1/2021

through 10/30/2021. The estimated impact days are likely to be

As a reminder, during this maintenance, Northwest will not be
