Notice of Strained Operating Condition (SOC)

Due to unseasonably warmer temperatures forecasted for the Front Range of Colorado combined with the ongoing Spring Storage Field Maintenance (Notice ID 122192), Colorado Interstate Gas Company, L.L.C. (CIG) ability to absorb imbalances into line pack is expected to be extremely limited. Therefore, (CIG) is declaring a Strained Operating Condition (SOC) pursuant to CIG FERC Gas Tariff, Second Revised Volume No. 1, (Tariff), General Terms and Conditions (GT&C) Section 11.2(a), for the transmission system to be effective for the Timely for Gas Day Thursday, 4/10/2025, 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 onto the system will not be accepted; payback off the system will be approved, absent other capacity concerns. Interruptible services may be impacted.

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

5. 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.

6. As described in notice #122306, Automatic Interruptible Parking and Lending Service (APAL) will not be available.

7. Storage customers should adjust flowing supplies to maintain storage injections at or below their Available Daily Injection Quantity (ADIQ).

In addition, to minimize pack imbalances and protect system integrity, CIG will be closely monitoring for any receipt and delivery points packing the system while following its Imbalance Management Procedures below.

Imbalance Management Procedures

CIG expects receipt and delivery operators to continuously manage their confirmations on a cycle-to- cycle basis to match actual flow rates. During the period addressed by this notice, flow control at receipts and/or non-performance caps at deliveries may be implemented for the upcoming Gas Day or during 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 non-performance, 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. 

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