QUESTAR APPOINTS NEW PRESIDENT OF PIPELINE SUBSIDIARY

SALT LAKE CITY — Questar Corp. (NYSE:STR) announced today that R. Allan Bradley has been appointed president and chief operating officer of subsidiary Questar Pipeline Co. effective Jan. 1, 2005.

Bradley, 53, previously spent 12 years as senior vice president of Coastal Corp. and El Paso Corp. subsidiaries. He left El Paso in 2002 to start a natural gas-consulting business, Ventura Energy LLC. Bradley began his career in 1975 with Exxon Corp. in the finance department, where he worked on domestic and international energy projects. From 1981 to 1990 he managed pipeline joint-venture projects and held various marketing and business-development positions with Texas Eastern Pipeline Co.

In the 1990s Bradley led Coastal’s successful development of the first foreign-owned natural-gas-fired power plant in Mexico (Samalayucca II), and the first foreign and privately owned natural gas pipeline in Victoria, Australia, as well as the development of a new midstream gas business in Canada. At El Paso, following the merger with Coastal, he led the commercial development of liquified natural gas-import projects.

 “Questar investors know that we must improve returns on invested capital in our pipeline business. Allan Bradley is going to help us do that,” said Keith O. Rattie, chairman, president and CEO of Questar Corp. “He brings new ideas, plus a passion for the pipeline business, and he complements our current management team very well.”

Bradley holds a B.S. in Management Science from Georgia Tech (1973) and an MBA in Finance from Tulane University (1975).

Questar is a natural gas-focused energy company with $5.1 billion in enterprise value. Headquartered in Salt Lake City, Questar engages in gas and oil development and production; gas gathering, processing and marketing; interstate gas transmission and storage; and retail gas distribution.

Detailed financial and operating statements are available on Questar's Web site.
