Under the OFO Recall Advisory, Shippers are required to: (1) recall capacity that is subject to an OFO recall provision; or (2) take other action that is acceptable to Northwest, to satisfy its OFO obligation. If the southbound scheduled quantities exceed the greater of Northwest’s design capacity of 672,000 Dth/d at Chehalis or the operationally available capacity at that location on that day, Northwest will provide Shippers with their specific OFO obligations by 4:00 p.m. MST. Shippers must comply with their OFO obligations no later than the Evening nomination deadline (5:00 p.m. MST). If an OFO is necessary for a given Gas Day, Northwest will wait until the Evening scheduling process to provide notice of a Declared Deficiency period and will make deficiency cuts to bring the nomination requests at the Chehalis compressor from the southbound design capacity of 672,000 Dth/d to the operationally available capacity of 492,000 Dth/d. If an OFO is not necessary, but a deficiency period is, Northwest will provide notice of a Declared Deficiency period and will make deficiency cuts in the Timely scheduling process to bring the nomination requests at the Chehalis compressor to the operationally available capacity of 492,000 Dth/d (or whatever NWP cannot mitigate during any day of the maintenance period), all pursuant to Sections 10.2 and 10.3 of Rate Schedule TF-1 in Northwest's Tariff. The deficiency period will continue until the work is completed. Shippers can monitor throughput quantities and obtain a copy of Northwest’s OFO procedures on Northwest’s website at www.northwest.williams.com.
