GATHERING, TRANSPORTATION AND STORAGEMarch 27th, 2018
FiledMarch 27th, 2018A substantial portion of the cost-of-service natural gas supplies Questar Gas receives under the Wexpro Agreement is contractually dedicated to the System-Wide Gathering Agreement between Questar Gas and Questar Gas Management Company (Gas Management). This long-standing agreement, effective September 1, 1993, incorporates a cost-of-service methodology to determine the reservation and usage rates for gathering services. Each year, new rates are calculated based on the previous- calendar-year costs-of-service allocable to Questar Gas and the previous-calendar-year natural-gas throughput. New rates are effective each year from September 1 through August 31. As specified in the agreement, sixty percent of the annual cost of service is allocated to the reservation charge and forty percent is allocated to the usage charge.
