Colorado Insterstate Gas Notice 122131

Strained Operating Condition (SOC) - Update

As an update to the Strained Operation Condition (SOC) declared in notice #122127 on January 6, 2025, pressures in the southern part of the Colorado Interstate Gas Company, L.L.C. (CIG) system have sufficiently recovered such that deliveries the (BIG) Big Blue (PIN #800089) location can resume effective for the Intraday 1 Cycle today, January 7, 2025. 

 
Receipt point operators supplying gas into CIG's pipeline should continue to monitor their flow rates to ensure natural gas flows do not fall short of scheduled quantities. Delivery point operators taking deliveries from CIG's pipeline should continue to monitor their flow rates to ensure natural gas flows do not exceed scheduled quantities.

Under the declared SOC, CIG will continue to take the following actions:

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

2. Interruptible withdrawals will not be available.

3. Payback onto the system will be accepted; payback off 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, Interruptible Swing Service and Rate Schedule SS-HP, Section 2, High Plains Interruptible Swing Service, will be available only to the extent that quantities delivered 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 for APAL will be suspended during the SOC.

6. Storage customers should adjust flowing supplies to maintain storage withdrawals at or below their Available Daily Withdrawal Quantity (ADWQ).

CIG will continue to monitor system conditions and will post an update to this notice as warranted by changes in system conditions.

Imbalance Management Procedures

CIG expects operators to continuously manage their confirmations on a cycle-to-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.
