The Utah Public Service Commission has issued an order that will cut Questar natural gas rates by nearly 9 percent for the typical residential customer, or $84 million. The resulting savings will be $64.38 annually for the average ratepayer. The decrease order reflects a drop in the cost of wholesale natural gas.

The PSC states the rates are interim and subject to further auditing by the Division of Public Utilities before becoming final. The rate changes went into effect Thursday.
