Subject: QUESTAR GAS - Gas Supply Communication - Customer Interruption/Hold to Scheduled Quantity

The Questar Gas service territory experiencing extreme cold and supply constraints.  Firm load demand on the Questar Gas distribution system requires that Questar Gas implement a service interruption for customers with interruptible load. 

Supply availability from upstream pipelines to the Questar Gas system is currently limited. Questar Gas is unable to provide additional supplies to make up for any short falls in the amount of gas being provided on behalf of your customers to the Questar Gas system. As a result, even if they have enough firm capacity on the Questar Gas system to cover their usage, they have also been required to limit their usage to not exceed the scheduled quantity being provided to the Questar Gas system for their use.

Their allowable usage for each hour will be equal to the lesser of their firm contract amount divided by 24 or their scheduled quantity divided by 24 for each hour of the interruption. This will be calculated for each hour based on the scheduled quantity available for the applicable hours of the interruption.
