Northwest Pipeline (“Northwest”) posted the following short term firm capacities at the request(s) of a
prearranged Shipper(s) on February 15, 2021, which day is designated by the General Terms and
Conditions of Northwest’s tariff as a non-Business Day:
Posting Package Vol Term Bid Period
21.032 Stanfield (r) – Ignacio/LaPlata (d) 296 2/16-19 2/15 7:45-8:45a
21.033 Opal (r) – Clay Basin (d) 20,000 2/15-16 2/15 10:45-11:45a
21.034 Stanfield (r) – Ignacio/LaPlata (d) 296 2/20-28 2/15 10:45-11:45a
Section 25.5(b) of the General Terms and Conditions of Northwest’s tariff states “Transporter’s
competitive bid postings will be subject to the following bid period timelines: (i) Transactions for a term
of thirty-one days or less will be posted for a competitive bid period of no less than one hour. Any one
hour posted bid period will commence at either 8:45 A.M., 11:45 A.M. or 4:45 P.M. Central Clock Time
(7:45 A.M., 10:45 A.M. or 3:45 P.M. Mountain Clock Time) on a Business Day.”
Business Day is defined in Section 1 of the General Terms and Conditions of Northwest’s tariff as,
“Monday through Friday, excluding Federal Banking Holidays for transactions in the U.S., and similar
holidays for transactions occurring in Canada and Mexico.”
The error in posting these capacities on a non-Business Day was identified after the capacities had been
awarded. Northwest offered the prearranged Shipper(s) the option to retain the capacities awarded or
to rescind the transactions with the option of re-requesting and re-posting the capacities on the
following Business Day, February 16, 2021
Northwest regrets this error and will be making system modifications to ensure that competitive bid
transactions for terms of thirty-one days or less cannot be posted on non-Business Days.
