To:  All Questar Gas (QGC) Transportation Customer Suppliers

To avoid imposing daily balancing restrictions over the long holiday weekend, QGC requests that supplies delivered to its system on behalf of transportation customers match actual usage. Please plan accordingly to ensure that supply versus usage stays within the normal +/-5% daily tolerance window. Also, ensure that imbalance payback nominations are in place to accurately reflect your plans to manage contract imbalances.

As provided for in QGC's Utah and Wyoming Natural Gas Tariffs (Utah tariff section 5.09, and Wyoming tariff section 5.06), QGC will allow +/- 5% of a customer's volumes delivered from upstream pipelines as a daily imbalance tolerance window. However, QGC may require customers or nominating parties to adjust deliveries or usage that contributes to an aggregate imbalance that would 1) require QGC to take action to maintain system integrity, or 2) reasonably be expected to force QGC to materially alter its prior day's planned level of a) gas purchases, b) QGC production, or c) storage injections or withdrawals.

"Due to additional unplanned maintenance, Indianola will not be available for agents to supply its southern system customers until further notice."
