Notice of Strained Operating Condition (SOC) - Pack

Colorado Interstate Gas Company, L.L.C. (CIG) is declaring a Strained Operating Condition (SOC) due to high linepack conditions across the CIG system.

Pursuant to CIG FERC Gas Tariff, Second Revised Volume No. 1, (Tariff), General Terms and Conditions (GT&C) Section 11.2(a), CIG is declaring a Strained Operation Condition (SOC) for the transmission system to be effective for Intrady 2 Cycle, Gas Day March 20, 2026 to remain in effect until further notice.

Accordingly, CIG will take the following actions:

1. NNT overrun INJECTION requests will be allocated to zero (0) dth.

2. Interruptible INJECTIONS will not be available.

3. Payback OFF the system will be accepted; payback ONTO the system will not be approved, absent other capacity concerns. Interruptible services may be impacted.

4. Pursuant to Part III: Rate Schedules - Rate Schedule SS-1, Section 2 and Rate Schedule SS-HP, Section 2, Interruptible Swing Service will be available only to the extent that quantities delivered are ABOVE daily scheduled quantities.

5. Rate Schedule SS-1 and SS-HP Operators with a balance owed to the Operator should nominate to reduce that balance to zero (0) dth owed to the Operator. 

6. Pursuant to GT&C Section 6.2 (k) of CIG's Tariff, Exemptions from CIG's Confirmation Balancing Exception Process will be suspended during the SOC.

7. Pursuant to Sections 2.1 (a) & (b) of Rate Schedule APAL-1 of CIG's Tariff, CIG will interrupt its Automatic Interruptible Parking and Lending Service (APAL) for the duration of this SOC.

8. Storage customers should adjust flowing supplies to maintain storage INJECTIONS at or below their Available Daily INJECTION Quantity (ADIQ).

In addition, receipt point operators supplying gas into CIG's pipeline should monitor their flow rates to ensure natural gas flows do not EXCEED scheduled quantities. Delivery point operators taking deliveries from CIG's pipeline should monitor their flow rates to ensure natural gas flows do not FALL SHORT OF scheduled quantities.

CIG will post an update to this notice as system conditions change.

Imbalance Management Procedures

CIG expects operators to continuously manage their confirmations on a cycle-by-cycle basis to match actual flow rates. During the period addressed by this notice, non-performance caps may be implemented for the upcoming Gas Day or even in the intra-day cycles for the current Gas Day, based on current pipeline operating conditions. As always, CIG will strive to give shippers and operators as much advance notice as possible before implementing non-performance caps. CIG will apply non-performance caps on a shorter time schedule and/or on weekends if operating conditions on the pipeline require such action.

To help avoid operational issues related to underperformance, CIG encourages all shippers to actively work with their suppliers and markets to ensure that all parties are aware of the importance of matching their actual flow rates with their confirmed scheduled flow rates.
