Notice of Strained Operating Condition (SOC)

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

Receipt point operators supplying gas into CIG's pipeline should 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 monitor their flow rates to ensure natural gas flows do not exceed scheduled quantities.

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 an SOC for the transmission system to be effective for INTRADAY 3 Cycle, Gas Day 1/6/2025, and TIMELY Cycle, Gas Day 1/7/2025, to remain in effect until further notice.

Accordingly, CIG will 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).

7. Due to current linepack conditions including under deliveries of required supply, operating pressures on the southern end of the CIG system have decreased such that CIG is experiencing an inability to deliver volumes to the following location(s) and will take the action as noted:

CIG will continue 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.
