Northwest asks that you direct any questions or comments to Dave Madsen (801-584-6864) or Brad Dillon (801-584-6832) by the morning of October 19, 2018. As discussed at the SAB meeting, Northwest intends to request a waiver from filing FERC Form No. 501-G because the reduction in the federal corporate income tax rate was addressed in Northwest's 2017 rate case settlement (Docket No. RP17-346). A draft copy of the proposed filing is available on Northwest's website under Regulatory/Proposed Tariff Filings at the following link: http://www.northwest.williams.com/NWP_Portal/ProposedTariffFilingsMenu.action dm/bd
