14.15 Operational Flow Order ("OFO")


(a) General. NAESB WGQ Nominations Related Standards 1.3.26 and

1.3.34 (Version 1.8) will apply and are incorporated by reference.


This Section 14.15 will apply to any Shipper, including any

Replacement Shipper, receiving firm service under any Rate Schedule

contained in Third Revised Volume No. 1 of Transporter's FERC Gas

Tariff. Transporter will issue OFOs when in its reasonable judgement

Transporter determines OFOs are necessitated by the conditions described

in Section 14.15(b) hereof, and when all other available operating

measures, including storage options and excluding any firm service

curtailment, have been exhausted.


This Section 14.15 also will apply to the implementation and

administration of contract-specific OFOs issued by Transporter within

the contract-specific OFO parameters set forth on Exhibit A of a Rate

Schedule TF-1 Service Agreement.


(b) OFO Operational Conditions. An OFO may be issued to create the

displacement capacity relied upon by Transporter to provide firm

transportation from a primary or alternate receipt point to a primary or

alternate delivery point to the extent that firm transportation using

alternate points is supported by primary point capacity which entitles

Shipper to primary firm transportation through the relevant corridor

established by its primary points ("corridor rights"). (Primary receipt

and delivery points are described in Sections 2 and 14.1 of the General

Terms and Conditions of Northwest's tariff.)


An OFO may be issued when scheduled receipt and deliveries:


(i) will not maintain sufficient operating pressures required to

satisfy firm transportation commitments;


(ii) will not prevent insufficient or excessive linepack for firm

transportation commitments; and
