Subject:  Overrun Entitlement and system update

Notice Text:

Due to prolonged colder than normal weather and the Jackson Prairie 
deliverability in the decline curve the following changes will be 
implemented on Northwest Pipeline to maintain integrity on its system:

Stage I (3%) overrun Entitlement north of the Plymouth compressor

Stage II (8%) overrun Entitlement in the Kemmerer to Plymouth
corridor 

Withdrawals from Jackson Prairie Interruptible Storage service will 
not be allowed until further notice. Parties who hold gas in SGS-2I 
service are not required to vacate. 

Jackson Prairie Park and Loan rates and volumes will be determined on 
a day-to-day basis. Please check the Daily Operational Report for the 
most up to date information remembering that Northwest may change 
rates and volumes up to 30 minutes prior to the beginning of any 
NAESB gas scheduling cycle based on the operational state of the 
pipeline. 

These changes are effective at the beginning of gas day February 9, 2019.
The Entitlement level will be evaluated on a daily basis based on system
line pack, storage levels, weather forecasts and upstream pipeline notices.
 
If you have any questions, please contact your Marketing Services
Representative or the Scheduling Hotline at 713-215-6301.
