Winter Weather Alert

Due to forecasted wind and heavy moisture for some portions of Wyoming Interstate Company, L.L.C. (WIC) production and service areas beginning Friday, April 18, 2025, WIC is preparing for potential weather-related supply shortfalls on its system. Therefore, to minimize draft imbalances and protect system integrity, WIC will be closely monitoring for any supply shortfalls drafting the system while following its Imbalance Management Procedures below.

Imbalance Management Procedures

WIC expects receipt 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 at receipts 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, WIC will strive to give shippers and operators as much advance notice as possible before implementing non-performance caps. WIC 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, 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.
