Notice Text:

On behalf of Puget Sound Energy, the operator of the Jackson Prairie
Storage Facility, and the Facility Partnership, Northwest Pipeline 
respectively informs its shippers that the facility will be unavailable 
for injections or withdrawals between October 1 through October 21, 
2019 to perform required annual testing and extended maintenance to 
ensure availability of the facility for the winter season. 

The Jackson Prairie facility maintenance corresponds with the annual 
testing of Dominions Clay Basin facility between October 8 through 
October 16, 2019.  During the impacted period, Northwest's balancing 
flexibility will be limited. Shippers are encouraged to stay on rate 
during this period to avoid potential entitlements.

posted daily and the maintenance schedule will be updated with any 
changes on Northwest's web site at www.northwest.williams.com.

Pipeline Hotline at 713-215-6301 if you have any questions.
