Colorado Interstate Gas Company, L.L.C. (CIG)

Notice of Strained Operating Condition (SOC)

Colorado Interstate Gas Company, L.L.C. (CIG) is declaring an SOC due to current high system inventory and upcoming bottom-hole testing that will be conducted at its four mainline storage fields beginning September 21 and continuing through October 28. These two factors limit current and future storage injection capabilities. Please refer to the CIG EBB posting #120131 and associated notices. CIG's ability to absorb imbalances into linepack leading up to and during the bottom-hole testing period is extremely limited. 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.

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 Timely Cycle, Gas Day Sep. 17, 2021 and 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 storage 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, Interruptible Swing Service will be available only to the extent that quantities received are below daily scheduled quantities.

5. Each Rate Schedule SS-1 Operator with an SS-1 balance owed to the Operator must nominate to reduce 10% or 5,000 dth (whichever is greater) of their outstanding SS-1 balance each day until balances are reduced to zero (0) dth owed to the Operator.  Balances not reduced to zero in this manner will become the property of CIG pursuant to Part III: Rate Schedules - Rate Schedule SS-1 Section 4.2(c) of CIG's tariff.

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

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

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 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 to ensure that all parties are aware of the importance of matching their actual flow rates with their confirmed scheduled flow rates.
