Cold Weather Alert

Due to the severe winter weather forecast to begin May 5, 2026, Wyoming Interstate Company, L.L.C. (WIC) is anticipating an increase in demand on its system which will limit its ability to manage imbalances associated with supply shortfalls.

WIC expects receipt operators to continuously manage their confirmations on a cycle-to-cycle basis to match actual flow rates.  Non-performance caps may be implemented for the upcoming Gas Day or even for the intra-day cycles for the current Gas Day, based on current pipeline operating conditions. WIC will apply non-performance caps on a shorter time schedule and/or on weekends if operating conditions on the pipeline warrant. Delivery point operators taking deliveries from WIC's system should monitor their flow rates to ensure flows do not exceed scheduled quantities.

To help avoid operational issues related to non-performance, WIC 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.

Furthermore, imbalances at receipt and/or delivery points may necessitate rapid elevation to additional measures, with minimal or no forewarning, such as Operational Flow Orders (OFOs) outlined in Section 11.1 of the General Terms and Conditions of the Third Revised Volume No. 2 of WIC's FERC Gas Tariff.

Weather forecasts related to your relevant areas should be monitored to assist in matching supply nominations to the anticipated demand.
