Contract No. 100314

 

THIS SERVICE AGREEMENT (Agreement) by and between Northwest Pipeline LLC (Transporter) and Avista Corporation (Shipper) is made and entered into on December 29, 2025 and restates the Service Agreement made and entered into on October 27, 2017.

 

WHEREAS:
  1. Shipper originally entered into contract #100314 pursuant to the provisions of the approved Joint Offer Settlement in Docket No. RP93-5-011 which unbundled the storage and redelivery transportation services, effective April 1, 1994.
  2. The storage redelivery service hereunder is related to that certain Rate Schedule JP-2 service agreement (#100408) dated October 04, 2007.
  3. The storage redelivery service hereunder is related to its storage rights under the Storage Gas Service Agreement (JP-2, #100408) dated January 12, 1994.
  4. Significant events and previous amendments of Contract 100314 reflected in the contract restatement include:

    1. By amendment dated June 2, 1995, Transporter and Shipper agreed to reduce the delivery volumes at Spokane Mead and increase the delivery volumes at Spokane (Kettle Falls) by 12, 862 Dth/d because of a facility agreement which expanded delivery capacity at Spokane (Kettle Falls).

    2. By amendment dated July 5, 1995, Shipper last made changes to the delivery points on the Agreement.

    3. By amendment dated November 17, 1996, the Contract-Specific Operational Flow Order ("CSOFO") through the Columbia river Gorge was 25,282 Dth/d (30,900 Dth/d / 55% = 56,182 Dth/d * 45% = 25,282 Dth/d) November 17, 1996 through October 31, 2004; 8,023 Dth/d (9,806 Dth/d / 55% = 14,587 Dth/d * 45% = 8,023 Dth/d) November 1, 2004 through September 30, 2009; and 6,591 Dth/d (8,056 Dth/d / 55% = 14,647 Dth/d * 45% = 6,591 Dth/d) October 1, 2009 through October 31, 2016.

    4. By amendment dated November 17, 1996, the CSOFO up the Spokane Lateral was 30,310 Dth/d from November 17, 1996 through October 31, 2004; 9,806 Dth/d from November 1, 2004 through October 31, 2009 and 8,056 Dth/d from November 1, 2009 through October 31, 2016.

    5. By amendment dated May 20, 1998, Transporter and Shipper agree that Article 4 of the Agreement shall be replaced with a Unilateral evergreen provision.

    6. By notice on December 14, 1998, Shipper changed its name from Washington Water Power Company to Avista Corporation effective January 1, 1999.

    7. By Amendment dated October 15, 1999, Transporter and Shipper agreed that, with the abandonment of Transporter's SGS-1 Service in conjunction with the Jackson Prairie Gas Storage Project Agreement dated January 15, 1998, as amended, and termination of Shipper's SGS-1 Agreement effective November 1, 1998, Shipper's storage redelivery capacity hereunder is related to that portion of Shipper's storage owenership rights under the Jackson Prairie Gas Storage Project Agreement dated January 15, 1998.

    8. By amendment dated March 26, 2008, Transporter and Shipper amended the non-conforming CSOFO language on Exhibit B to reflect the remaining CSOFO through (1) the Columbia River Gorge of 8,023 Dth/d through October 31, 2009 and 6,591 Dth/d through October 31, 2016, and (2) up the Spokane Lateral of 9,806 Dth/d through October 31, 2009 and 8,056 Dth/d through October 31, 2016.

    9. By amendment dated October 14, 2009, Transporter and Shipper agreed to move 13,192 Dth/d of primary delivery point rights (MDDO's) from Spokane (Kettle Falls) to Nine Mile Falls due to the plans to permanently disconnect the Spokane (Kettle Falls) meter station from Transporter's system.

    10. By amendment dated October 19, 2009, Transporter and Shipper agreed to remove Exhibit B in its entirety. Prior to this amendment, the Exhibit B contained two non-conforming CSOFO's that have since expired. Transporter agreed to remove the final CSOFO's because Shipper agreed to amend the path on contract 193649 from Jackson Prairie receipt point to Sumas delivery point back to its original path of Jackson Prairie receipt point to Spokane Mead delivery point. The amendment on 193649 reverses the negative impacts of the original amendment and restores the displacement that Transporter's system relies upon through these corridors.

    11. By amendment dated August 3, 2010, 2,470 Dth/d of primary delivery point rights (MDDO's) were amended from the Spokane (Kettle Falls) Delivery Meter to the Nine Mile Falls Delivery Meter to facilitate the permanent disconnect of the Spokane (Kettle Falls) meter station from Transporter's system.

    12. By amendment dated June 25, 2012 Transporter and Shipper agreed to (1) add the following two non-conforming provisions: (i) Moscow Capacity; and (ii) FERC Approval, and (2) relocate 2,622 Dth/d of MDDOs from the Moscow Delivery Meter to the Connell and Colfax Delivery Meters by 1,000 Dth/d and 1,622 Dth/d respectively.

    13. By amendment dated June 25, 2012 Transporter and Shipper agreed to realign the following MDDOs on the Coeur d'Alene Lateral: 2,450 Dth/d from the Kellogg Delivery Meter; 20 Dth/d from the Page Mine Delivery Meter; 61 Dth/d to the Smelterville Delivery Meter; 106 Dth/d to the Pinehurst Delivery Meter; 285 Dth/d to the Coeur d'Alene East Delivery Meter; 118 Dth/d to the Coeur d'Alene West Delivery Meter; 152 Dth/d to the Post Falls Delivery Meter; and 1,748 Dth/d to the McGuire Delivery Meter.

    14. By amendment dated June 25, 2012 Transporter and Shipper agreed to add a delivery pressure condition on Exhibit A to reduce the delivery pressure at the Kellogg Delivery Meter from 200 psig to 150 psig through October 31, 2017.

    15. By amendment dated June 25, 2012 Transporter and Shipper agreed to amend the Primary Term End Date on Exhibit A from October 31, 2016 to October 31, 2017, along with modifications to the non-conforming provision relating to the Primary Term End Date on Exhibit B.

    16. By amendment dated July 3, 2012 Transporter and Shipper agreed to amend the Primary Term End Date on Exhibit A from October 31, 2017 to November 1, 2017, along with corresponding modifications to the non-conforming provisions relating to the Primary Term End Date on Exhibit B. Under the terms of a settlement agreement with Shipper, certain point amendments are to become effective November 1, 2017. Because the Primary Term End Date preceded the effective date of the amendments, the new Primary Term End Date is necessary in order for Transporter's system to be able to execute the provisions relating to the Settlement Agreement.

    17. By restatement dated August 8, 2013, Transporter and Shipper agreed to remove the non-conforming provisions titled Moscow Capacity and FERC Approval as a result of Transporter installing the necessary facilities on July 22, 2013 to support Avista's historical contractual rights on the lateral. Therefore, pursuant to the Moscow Capacity non-conforming provision, the Parties agree to realign MDDOs of 1,000 Dth/d from Connell and 1,622 Dth/d from Colfax back to the Moscow delivery location.

    18. By restatement dated October 27, 2017, Transporter and Shipper further agree to restate the Agreement to: (1) remove the Exhibit B because the non-conforming provisions no longer apply, (2) terminate the future Amendments dated July 9, 2012 and August 21, 2013, both with an effective date of November 1, 2017, and (3) change the Primary Term End Date from November 1, 2017 to November 30, 2018.

    19. Transporter and Shipper agreed to restate the Agreement to reflect the current form of service.
