hereby files with the Securities and Exchange Commission, pursuant to Rule 2, its statement claiming exemption as a holding company from the provisions of the Public Utility Holding Company Act of 1935, and submits the following information:

     1.     Name, state of organization, location and nature of business of claimant and every subsidiary thereof, other than any exempt wholesale generator (EWG) or foreign utility company in which claimant directly or indirectly holds an interest.

     Questar Corporation ("Questar" or the "Company") is a Utah corporation with its principal executive office and principal place of business at 180 East 100 South Street, P.O. Box 45433, Salt Lake City, Utah 84145-0433. On October 2, 1984, the Company filed an initial Form U-3A-2 with the Securities and Exchange Commission following a holding company reorganization in which Questar Gas Company ("Questar Gas") became a subsidiary of Questar. Questar subsequently filed a Form U-3A-2 on March 1, 1985, and on or before each subsequent March 1 to the present time.

     As a parent company, Questar provides certain administrative services, e.g., personnel, public relations, communications, tax, financial, and audit, to companies within the consolidated group. Questar has three primary direct subsidiaries: Questar Regulated Services Company, a Utah corporation ("Regulated Services"); Questar Market Resources, Inc., a Utah corporation ("Market Resources"); and Questar InfoComm, Inc., a Utah corporation ("Questar InfoComm"). The Company owns 100 percent of the common stock issued by each of these directly held subsidiaries.

     Regulated Services has three subsidiaries: Questar Gas, a Utah corporation; Questar Pipeline Company, a Utah corporation ("Questar Pipeline"); and Questar Energy Services, Inc. ("QES"). Questar Gas is engaged in the retail distribution of natural gas in the states of Utah, Wyoming, and Idaho. Questar Gas also transports natural gas for industrial users in Utah and Wyoming. Questar Gas's activities in Utah and Wyoming are subject to regulation by the respective Public Service Commissions in those states. Pursuant to a special contract with the Idaho Public Utilities Commission, Questar Gas's natural gas service in Idaho is regulated by the Public Service Commission of Utah. Questar Gas's customers in Idaho are served under the provisions of its Utah tariff. Questar Pipeline currently transports and stores natural gas in interstate commerce in the Rocky Mountain states of Utah, Wyoming, and Colorado. It has the following subsidiaries: Questar Transportation Services Company, Questar Southern Trails Company, Questar Overthrust Pipeline Company, and Questar Overthrust Company. Each subsidiary is incorporated in Utah and conducts transmission or processing operations. QES performs energy management services and other activities.

     Questar InfoComm owns data processing and communications systems, and performs data processing and communications services for other members of the consolidated group and third parties. It also owns a majority interest in Consonus, Inc., a Utah corporation that offers data security and related activities.

     Market Resources engages in various businesses not subject to state utility regulation through several subsidiaries: Wexpro Company ("Wexpro"), which conducts oil and gas development and production activities on certain producing properties for the benefit of Questar Gas in the Rocky Mountain region; Questar Exploration and Production Company ("QEP"), which engages in oil and gas exploration and related development and production activities throughout the western and Midcontinent portions of the United States in its name and through Shenandoah Energy, Inc.; Questar Energy Trading Company ("QET"), which conducts energy marketing activities; and Questar Gas Management Company ("QGM"), which is engaged in gathering and field processing activities. Neither Market Resources nor any of its subsidiaries is a "public utility company," as such term is defined in the Act. All companies owned by Market Resources have their principal offices at 180 East 100 South Street, Salt Lake City, Utah, but the group also has offices in Denver, Colorado, Oklahoma City and Tulsa, Oklahoma.

     With the exception of Questar Gas, none of the companies directly or indirectly owned by Questar is a "public utility company" as that term is defined in the Public Utility Holding Company Act of 1935, as amended (the "Act"). Questar's directly held subsidiaries have their principal executive offices at 180 East 100 South, Salt Lake City, Utah. Questar does not have any interest, direct or indirect, in any exempt wholesale generator or foreign utility company.

     2.     A brief description of the properties of claimant and each of its subsidiary public utility companies used for the generation, transmission, and distribution of electric energy for sale, or for the production, transmission, and distribution of natural or manufactured gas, indicating the location of principal generating plants, transmission lines, producing fields, gas manufacturing plants, and electric and gas distribution facilities, including all such properties which are outside the state in which claimant and its subsidiaries are organized and all transmission or pipelines which deliver or receive electric energy or gas at the borders of such state.

     Questar Gas, which is a "gas utility company" for purposes of the Act, was distributing natural gas to 750,128 sales and transportation customers (defined as active meters) in Utah, southwestern Wyoming, and southeastern Idaho as of year-end 2002. Of these customers, 725,097 were located in Utah, 23,371 were located in southwestern Wyoming, and 1,660 were located in southeastern Idaho. Questar Gas owns and operates approximately 22,815 miles of street mains, service lines and interconnecting pipelines in its distribution system, including approximately 21,822 miles in its Utah distribution system.

     Under the terms of a settlement agreement among Questar Gas, Wexpro and various state parties ending several years of litigation, Questar Gas owns the natural gas produced from gas reservoirs that were productive as of August 1, 1981. Most of these productive reservoirs are located in southwestern Wyoming and northwestern Colorado; most of the gas produced from such reservoirs is distributed to Questar Gas's retail natural gas customers. Gas owned by Questar Gas but produced from reservoirs outside the location of pipelines owned by Questar Pipeline is generally sold to or exchanged with other companies. Gas owned by Questar Gas plus gas attributed to royalty interest owners in the same reservoirs constituted 45 percent of Questar Gas's total gas supply in 2002 and is reflected in Questar Gas's rates at "cost-of-service" prices.

     Questar Gas is directly responsible for all gas acquisition activities. Questar Pipeline transports the gas volumes purchased directly by Questar Gas and transports cost-of-service gas owned by Questar Gas and produced by Wexpro. Questar Gas takes delivery of gas from Questar Pipeline and an unaffiliated interstate pipeline at various points in Utah, Wyoming, and Colorado. Questar Gas does not currently own any interstate transmission lines or gas manufacturing plants. QET markets natural gas and electricity, but does not own any distribution facilities in connection with such activities.

     3.     The following information for the last calendar year with respect to claimant and each of its subsidiary public utility companies:

            (a)     Number of kwh of electric energy sold (at retail or wholesale) and Mcf of natural or manufactured gas distributed at retail.

     During the 2002 calendar year, Questar Gas sold 101,525 thousand decatherms ("Mdth") of natural gas, including 90,796 Mdth at retail (defined as residential and commercial customers), and transported 46,459 Mdth of natural gas. (Questar Gas generally reports volumes in decatherms ("Dth"); a Dth is equal to ten therms or one million Btu. In Questar Gas's gas system, each thousand cubic feet of natural gas contains approximately 1.051 Dth.) For purposes of this report, Questar Gas's "retail" customers are general service or residential and commercial customers. The 10,729 Mdth difference between the total sales number and the retail sales number includes sales to industrial customers that are not involved in resale transactions and sales of natural gas to refueling stations that are resold for natural gas vehicles. Questar Gas's total revenues for 2002 were $595,511,000, of which $549,665,000 were attributable to its operations in Utah, $22,616,000 were attributable to its operations in Wyoming, $111,000 were attributable to its operations in Colorado, and $1,033,000 were attributable to its operations in Idaho. (The one contract for service in Colorado expired before year-end 2002.) (Questar Gas's total 2002 revenues included $22,085,000 in addition to revenues from gas deliveries.) Questar Gas did not distribute any manufactured gas during such calendar year. Questar Gas is the only public utility company among the Company's subsidiaries. Questar itself did not make any sales of natural or manufactured gas during 2002.

     The Company itself did not sell any natural or manufactured gas.
