|The interim financial statements reflect all adjustments which are, in the opinion of management, necessary for a fair presentation of the results of operations for the interim periods presented. All such adjustments are of a normal recurring nature.  While the transportation and storage operations are influenced by weather conditions, the straight fixed-variable rate design, which allows for recovery of substantially all fixed costs in the demand or reservation charge, reduces the earnings impact of weather conditions.

|Questar Pipeline, directly or indirectly through subsidiaries, has interests in partnerships accounted for on an equity basis.  Questar TransColorado (a subsidiary of Questar Pipeline) owns 50% of TransColorado Pipeline (a general partnership) and Questar Pipeline owns 90% of Overthrust Pipeline (a general partnership).  Questar Pipeline does not have control of Overthrust Pipeline because the approval of the other partner is required for significant partnership decisions.  Transportation of natural gas is the primary business activity of these partnerships.  Summarized operating results of the partnerships are listed below.

|Operating and maintenance (O & M) expenses were higher in the 2002 periods primarily because of legal fees and the start-up operations of the Southern Trails pipeline partially offset by lower fuel costs.  Legal expenses were higher in the 2002 periods by $1.1 million in the second quarter and $1.8 million in the first half compared with the year earlier periods due to the ongoing litigation regarding TransColorado pipeline.                                                                                                                              



|Expenses in preparation for commencing the flow of gas through the eastern segment of the Southern Trails pipeline increased O & M expenses by $ .4 million in the first half of 2002.  The $100 million, eastern segment began commercial operations on June 25, 2002.  The pipeline's 80 million cubic feet per day capacity is fully subscribed.  The Company is evaluating the economics of a 60-mile expansion of the 12- inch portion of the eastern segment (the remainder of the pipeline is 16-inch) to enable the segment's capacity to increase to 120 million cubic feet per day.  The Company continues to market the 120 million cubic feet capacity of the western segment of the Southern Trails pipeline, while at the same time it considers other options, including selling the pipeline.

|The Company's share of the TransColorado partnership was a pretax profit of $2.2 million for the second quarter of 2002.  The unusually wide basis differentials reflected between gas prices in the Rockies versus prices in the San Juan Basin have the pipeline running near-capacity.  TransColorado reported a $1.7 million pretax loss for the year earlier quarter.

|Net cash provided from operating activities of $25.7 million in the first half of 2002 was $3.2 million less than the amount reported for the same period of 2001 due to changes in operating assets and liabilities.

|Questar Pipeline used net cash flow provided from operating activities and borrowed $60.1 million from Questar Corp. in the first half of 2002 to finance capital expenditures and pay dividends.  Forecasted capital expenditures for 2002 are expected to be financed from net cash provided from operating activities and the issuance of long-term debt and common equity.  The Company loans excess funds to Questar Corp. or borrows from Questar Corp. for short-term needs.  Such notes receivable and notes payable bear market interest rates.  The FERC recently issued a notice of proposed rule making regarding cash management arrangements.

|Moody's review of Questar Pipeline and some of its affiliated companies is still pending. On May 2, 2002, Moody's Investors Service placed Questar Pipeline Company under review for a possible rating downgrade of the Company's A1 senior unsecured debt.  Moody's also placed Questar Pipeline's parent company, Questar Corporation and affiliated companies, Questar Gas and Questar Market Resources under review.  The review was prompted by Moody's concern of Questar's increased financial leverage following an acquisition in 2001 and the shift in business mix towards nonregulated businesses.  Moody's review will assess Questar's plan to reduce its leverage and to manage increased business risk and commodity price exposure. Lower debt ratings would increase the Company's cost of debt.  Unless ratings fall below investment grade, a downgrade would not materially affect the Company's growth strategy.

All statements other than statements of historical facts included or incorporated by reference in this report, including, without limitation, statements regarding the Company's future financial position, business strategy, budgets, projected costs and plans and objectives of management for future operations, are forward-looking statements.  In addition, forward-looking statements generally can be identified by the use of forward-looking terminology such as "may", "will", "could", "expect", "intend", "project", "estimate", "anticipate", "believe", "forecast", or "continue" or the negative thereof or variations thereon or similar terminology.  Although these statements are made in good faith and are reasonable representations of the Company's expected performance at the time, actual results may vary from management's stated expectations and projections due to a variety of factors.

|Item 1.   Legal Proceedings.
|----------------------------



|There are various legal proceedings pending against Questar Pipeline Company ("Questar Pipeline" or the "Company") and its affiliates.  Management believes that the outcome of these cases will not have a material adverse effect on the Company's financial position or liquidity.
|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|a.  KN TransColorado, Inc. v. Questar Corp., No. 00CV129 (Dist. Ct. Colo.).  The trial court judge has not entered an order in the complex litigation involving the partners in TransColorado Gas Transmission Company ("TransColorado").  The trial ended May 2, 2002, and the parties to the litigation filed post-trial briefs on or about June 11, 2002.  The case, which was originally filed in June of 2000 in a Colorado state district court located in Glenwood Springs, Colorado, involves the validity of a contractual right claimed by Questar TransColorado, Inc. ("QTC"), a direct subsidiary of Questar Pipeline Company ("Questar Pipeline") and a third-tier subsidiary of Questar, to put its 50 percent interest in the TransColorado pipeline project to KN TransColorado, Inc. ("KNTC").  KNTC, which is an affiliate of Kinder Morgan, Inc., is QTC's partner in the project.

|In the claims and counterclaims filed in the case, each party sought damages in excess of $150 million.  The Questar parties expect to receive the judge's order before the end of the third quarter.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                



|b.  Grynberg v. Questar Pipeline Co., No. 20010731-SC (Utah Sup. Ct.).  The Utah Supreme Court has not set a hearing date for the appeal filed by Jack Grynberg, an independent producer, after a Utah state district court judge granted defendants' motion for summary judgment and dismissed the complaint.  In this lawsuit, which was originally filed in September of 1999 in a Utah state district court, Grynberg claims that Questar Pipeline and other Questar affiliates including Questar Gas Management Company ("QGM") and Questar Energy Trading Company ("QET"), mismeasured gas volumes attributable to his working interest in specified wells located in southwestern Wyoming.  The district court granted the motion for summary judgment filed by the Questar defendants in March of 2001.  Grynberg is seeking damages of $27 million.

|c.  United States ex rel. Grynberg v. Questar Corp., Civil No. 99 MD 1604, Consolidated Case MDL No. 1293 (D. Wyo.).  Questar, Questar Pipeline, QGM, and other named affiliates continue to be involved in joint defense group that is contesting numerous claims filed by Mr. Grynberg under the federal False Claims Act against pipelines and their affiliates.  The case against the Questar defendants was originally filed under seal in Colorado's federal district court in June of 1997, and stayed under seal until the Department of Justice determined not to get involved.  In May of 1999, the Questar defendants were officially served with the second amended complaint that was filed with the Colorado district court in February of 1998.  The cases have been consolidated for discovery and pre-trial motions in Wyoming's federal district court.  The cases involve allegations of industry-wide mismeasurement and undervaluation of gas volumes on which royalty payments are due the federal government.  The complaint seeks treble damages and imposition of civil penalties, but specific damage amounts have not been claimed.

|The presiding judge, who previously denied the defendants' motion to dismiss, recently advised the parties of his intent to establish a scheduling order in the near future and asked the parties to submit recommendations to him.

|d.  Price v. Gas Pipelines, No. 99 C 30 (Dist. Ct. Kan.).  QET, QGM, Wexpro, Questar Gas Company ("Questar Gas"), and Questar Pipeline are among the 147 named defendants in this purported nation-wide class action case in which the named plaintiffs allege systematic mismeasurement of natural gas volumes from private and state lands and resulting underpayment of royalties.  This case was originally filed in the Kansas district court in September of 1999, but was removed to federal district court and consolidated with the Grynberg cases mentioned above in Wyoming's federal district court.  It was subsequently transferred back to Kansas.  The plaintiffs have not set forth specific dollar amounts in damages.
|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|The defendants filed motions to dismiss and those motions were argued on November 29, 2001.  The court has not issued any rulings.  In addition, certain defendants, including the Questar defendants, have filed motions to dismiss the pending action for lack of personal jurisdiction; such motions are set for oral argument on August 29, 2002.  Class certification briefing will begin on September 3, 2002.

|As previously mentioned under Item 1., Questar Pipeline's subsidiary QTC is a 50 percent partner in TransColorado.  This partnership was originally formed in 1990 to build and operate the TransColorado pipeline that commenced operations March 31, 1999.  (The partnership agreement was subsequently amended in 1995, 1997 and 1998.)  This pipeline extends from a point on Questar Pipeline's system 25 miles east of Rangely in northwestern Colorado and extends 292 miles to the Blanco hub in northwestern New Mexico. The partnership agreement is filed as Exhibit 10.3 to Questar Pipeline's 2001 Annual Report on Form 10-K.

|Questar Pipeline also has a 90 percent interest in and is the operating partner of Overthrust Pipeline Company ("Overthrust"), a general partnership that was organized in 1979 to construct, own and operate the Overthrust segment of Trailblazer Pipeline System ("Trailblazer").  The 88-mile Overthrust segment is the western-most of Trailblazer's three segments; Trailblazer itself is an 800-mile pipeline that transports gas from producing areas in the Rocky Mountains to the Midwest.  The remaining 10 percent is owned by an affiliate of El Paso Corporation.  The partnership document does not constitute a material contract for Questar.

|Gains and losses on the reacquisition of debt are deferred and amortized as debt expense over the would-be remaining life of the retired debt or the life of the replacement debt in order to match regulatory treatment.  The cost of the early retirement windows offered to employees is capitalized and amortized over a five-year period in accordance with regulatory treatment.   The Company records cumulative increases in deferred taxes as income taxes recoverable from customers.  The Company has adopted procedures with the FERC to include under- and over-provided deferred taxes in customer rates on a systematic basis.  Questar Pipeline uses the deferral method to account for investment tax credits as required by the FERC.  Regulation allows the Company to recover costs, but does not provide for a return on these assets.  A list of regulatory assets at December 31 follows:
