After receiving feedback from Shippers, Northwest has revised its proposed tariff filing mentioned in All Shippers

Letter #20-051 relating to a Realignment Shipper’s unutilized MDQ pursuant to Section 14.15(d)(iii) of the General

Terms and Conditions of the Tariff. Under the proposed change, Northwest is reducing the number of exceptions

from four to two. In addition, Northwest will provide shippers the flexibility in the nomination process to determine

which shipper will receive the credit towards their unutilized MDQ when a downstream gas supply is transported to a

downstream non-associated pool.

The revised Tariff 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').

In addition, an updated presentation diagramming and explaining the two exceptions mentioned in the proposed

tariff language is available on Northwest’s website under Other at the following link:

http://www.northwest.williams.com/NWP_Portal/ (click ‘Other’, then ‘Realignment Shippers Unutilized

MDQ Scenarios (Revised)’ located under Shipper Advisory Board).

Please direct comments and concerns to Mike Rasmuson (801-584-7278) or Dave Madsen (801-584-6864) on or

before May 19, 2020.
