The following restriction, as provided for in Questar Gas Company’s Utah Natural Gas Tariff (Utah Tariff) Section 5.09 and Wyoming Natural Gas Tariff (Wyoming Tariff) Section 5.06, is required due to warmer-than-normal forecasted temperatures, along with Questar Gas’ need to maximize its storage injection capacity:

July 3rd and until further notice:                     
A transportation customer’s supply must match its usage within a +/-5% tolerance window.

Imbalance payback should not be nominated, unless approved by Questar Gas’ Gas Supply personnel on a case-by-case basis.

After aggregation of imbalances at an agent level, and after the allowed trading period, penalties as outlined in the Utah and Wyoming Tariffs will be assessed for those imbalances remaining outside of the balancing tolerances outlined above.

Thank you for your attention in this matter.
