Northwest asks that you provide any comments or concerns on or before March 11, so Northwest can respond prior to the filing being submitted to FERC. Please direct comments and concerns to Dave Madsen (801-584-6864) or Josh Taylor (801-584-6673). Northwest plans to make a tariff filing to propose: (1) the addition of index-based discount rate language, (2) the removal of outdated language in Section 3.5 of the General Terms and Conditions regarding the ranking of receipt gas not meeting the tariff quality specifications, (3) the addition of language describing how negotiated rates, which include an option fee, will be calculated for the purposes of determining scheduling priorities and evaluating available capacity bids, and (4) other miscellaneous housekeeping/cleanup changes. 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/ (click 'Regulatory,' then 'Proposed Tariff Filings'). dm/bd/jt
