Questar Gas: Mountain Fuel's New Name
SALT LAKE CITY -- The company that sells natural gas to more than 625,000
customers in Utah, Idaho and Wyoming is no longer known as Mountain Fuel.  On
Thursday, Jan. 1, the company's new name officially changed to Questar Gas
Company.  
     "I want to assure our customers that there has been no change in
ownership of the company," said Nick Rose, president and CEO.  For more than
60 years, Mountain Fuel has been a part of an integrated energy company known
for outstanding customer service.  We want to present a single name in the
evolving energy market that will come to represent the entire spectrum of
products and services offered by Questar.  The Mountain Fuel name is
identified primarily with gas distribution.  The Questar name will reflect all
facets of the industry.
     Questar Corp. traces its roots to 1928, when a holding company, Western
Public Service Corp., was formed to bring natural gas to northern Utah from
southwestern Wyoming. At that time, Mountain Fuel Supply Co. was the name of
the oil and gas exploration and production affiliate. In 1935, the
shareholders voted to reorganize Western Public Service Co. as a single
company and chose the Mountain Fuel name to represent the reorganized company.
     Almost 50 years later, in 1984, Mountain Fuel shareholders voted to
return to the holding-company structure. They chose the name Questar Corp. for
the new parent company.
     Questar Corp. is one of the largest companies with headquarters in Utah.
It has almost 2,500 employees and about $1.8 billion in assets distributed
between Regulated Services, consisting of retail natural gas distribution and
interstate gas transportation, and Market Resources, which includes gas and
oil exploration and production, wholesale and retail energy trading and
marketing, gas gathering and other field services.
