Item 5.  Other Events.

     Questar Corporation ("Questar" or the "Company"), through its
affiliates Questar Exploration and Production Company and Wexpro
Company, is actively involved in drilling operations in the Pinedale
area of western Wyoming.  The two Questar entities have an
approximately 60 percent working interest in 14,800 gross acres in
the Mesa area of the Pinedale Anticline.  The Company's subsidiaries
currently have five drilling rigs in the area and have tentatively
planned to drill 130 wells on 80-acre spacing over the next several
years.  Questar affiliates drilled two successful exploratory wells
in the area with an average initial production rate of 11 million
cubic feet of gas per day.

     If future wells are as successful as the first wells, Questar
could add 300-400 billion cubic feet of  gas (net of royalty
requirements) to reserves.  (This estimate includes cost-of-service
and noncost-of-service reserves.  As of year-end 1999, Questar
reported proved reserves of 613 billion cubic feet equivalent for
noncost-of-service properties and reserves of 358 billion cubic feet
equivalent for cost-of-service properties.)  The wells are being
drilled pursuant to restrictions imposed by the Wyoming state office
of the Bureau of Land Management; these restrictions only permit
Company  affiliates to drill five months of any year.  Questar
currently has the legal ability to drill on 40-acre spacing, if
technically viable; drilling on 40-acre spacing could double the
number of wells that can be drilled in the area and the resulting
reserves.
