Item 5.  Other Events.

       The Public Service Commission of Utah (PSCU) has denied Questar Gas
Company's (Questar Gas or the Company) request to recover in the Company's
semiannual pass-through rate filing the cost of removing CO2 from gas processed
at a new plant near Price, Utah.  Some of the natural gas Questar Gas delivers
to its customers must be processed to remove CO2, ensuring a natural gas
composition that can operate safely and efficiently in customers' appliances.

       The required gas processing has been estimated to cost $7.5 to $8.5
million annually. The commission's decision forces the Company to reverse about
$1.9 million of pre-tax income in the fourth quarter of 1999, which the Company
previously anticipated recovering through its semiannual pass-through rate
filings.  The Company will also incur an additional $600,000 to $700,000 in
monthly operating expenses going forward.

       In denying the Company's request, the commission provided guidance for
the Company to seek recovery of future CO2-removal costs through other
rate-making procedures.

       "We disagree and are extremely disappointed with the commission's
decision," said D. N. "Nick" Rose, Questar Gas president and CEO.  "We believe
the fair way to pay for this processing, which is required for safe natural gas
supplies for our customers, is through a pass-through rate proceeding."

       Unlike Utah, the Public Service Commission of Wyoming (PSCW) staff has
recommended immediate cost coverage for Wyoming's share of these costs.

       According to Rose, the Company will ask for a rehearing.  For ongoing
costs, the Company will explore other cost-recovery options including filing
a general rate case as the PSCU suggested its order.

       Questar Gas Company is a wholly-owned subsidiary of Questar Corporation
(Questar).  Questar is a Salt Lake City-based integrated energy resources and
services company with $2.2 billion in assets.
