Subject:  Supply Shortage OFO Communication

Notice Text:

Due to the anticipated impacts associated with Enbridge's posted 
maintenance beginning February 27, 2019 along with the reduced 
deliverability at Jackson Prairie, Northwest would like to provide 
additional information on how a potential Supply Shortage OFO will be 
administered in addition to the communication that was provided in the All 
Shipper Notice No. 19-043. 

If Shippers' OFO compliance after the completion of the evening nomination 
cycle is insufficient to bring the primary firm nomination requests down to 
the greater of the physical design capacity or the posted operational 
capacity, Northwest will invoke a Supply Shortage OFO by posting an All 
Shipper Notice. Below are the actions that will take place under each OFO 
category if such Supply Shortage OFO is invoked.

Realignment OFO - Cut previously scheduled quantities during the 
Intraday 1 cycle going through the constraint point associated with 
any Shipper subject to a Realignment OFO that has failed to comply 
with such Realignment OFO. Shippers that are subject to the 
Realignment cuts may need to reduce load to avoid Entitlement 
penalties pursuant to 14.6 of the General Terms and Conditions of 
the Tariff.

Contract-specific OFO and Must-flow OFO - Shippers subject to a 
Contract-specific or Must-flow OFO will then have until the Intraday 
1 nomination cycle to comply by either nominating the necessary 
displacement gas or taking other actions acceptable to Northwest. 
If, after exerting good faith efforts, Shipper is unable to obtain 
physical supply at any point on the opposite side of the constraint 
point, then in order to avoid penalties for noncompliance, Shipper 
must attest to such facts by providing Northwest with an acceptable 
affidavit, executed by an officer of the company. Any such affidavit 
must be provided to Transporter prior to the Intraday 1 nomination 
cycle for Shipper to be exempt from penalties.

Supply Shortage OFO - Allocate the greater of the physical design 
capacity or posted operational capacity by allocating Shipper's 
previously scheduled primary firm scheduled quantities pro rata 
based on the Shipper's primary firm corridor rights through the OFO 
constraint point in the constraint direction. Shippers that are 
subject to Supply Shortage OFO actions may need to reduce load to 
avoid Entitlement penalties pursuant to 14.6 of the General Terms 
and Conditions of the Tariff.

Any Shipper that fails to comply with its OFO obligations will be subject 
to the OFO penalties outlined in Section 14.15 of General Terms and 
Conditions of Northwest's tariff.

Northwest has posted on its website the presentation that was associated 
with the conference call on Supply Shortage OFO tariff filing. The
