Notice Text:
As posted in the maintenance schedule on Northwest Pipeline’s Website and referenced in All Shipper Notice #24-104, Northwest was scheduled to begin the Blue Lake Pipe Replacement and The Portland Hydro Test (Gorge Outage) on Gas Day July 30, 2024, through Gas Day August 13, 2024. However, due to current State and County Environmental Fire Restrictions, the outage schedule has now been pushed out to begin on Gas Day August 2, 2024, and will last through Gas Day August 18, 2024.
During this outage, the pipeline will be isolated between the Washougal and Willard corridor. The cut points will be the Washougal South Constraint which will be limited to net 0 Dth/d southbound and the Willard CS which will be limited to net 0 Dth/d northbound.
If primary nomination requests through the Washougal South Constraint exceeds the available capacity of net 0 Dth/d southbound (or whatever NWP cannot mitigate during any day of the maintenance), pursuant to Sections 10.2 and 10.3 of Rate Schedule TF-1 in Northwest's Tariff, Northwest will give notice of a Declared Deficiency Period based on a design capacity of 407,741 Dth/d southbound. The deficiency period will continue until the work is completed on Gas Day August 18, 2024.
If primary nomination requests through Willard CS exceeds the available capacity of net 0 Dth/d northbound (or whatever NWP cannot mitigate during any day of the maintenance), pursuant to Sections 10.2 and 10.3 of Rate Schedule TF-1 in Northwest's Tariff, Northwest will give notice of a Declared Deficiency Period based on a design capacity of 540,000 Dth/d northbound. The deficiency period will continue until the work is completed on Gas Day August 18, 2024.
