QUESTAR GAS COMPANY  NOTES ACCOMPANYING THE CONDENSED FINANCIAL STATEMENTS  Note 1  Nature of Business  Questar Gas Company (Questar Gas or Company) is a wholly owned subsidiary of Questar Corporation (Questar). The Company provides retail natural gas distribution in Utah, southwestern Wyoming and a small portion of southeastern Idaho. Questar Gas is regulated by the Public Service Commission of Utah (PSCU) and the Public Service Commission of Wyoming (PSCW). The Public Utility Commission of Idaho has contracted with the PSCU for rate oversight of Questar Gass Idaho operations.  Note 2  Basis of Presentation of Interim Financial Statements  In July 2009 the Financial Accounting Standards Board (FASB) completed a revision of non-governmental U.S. GAAP into a single authoritative source and issued a codification of accounting rules and references. Authoritative standards included in the codification are designated by their Accounting Standards Codification (ASC) topical reference, and new standards will be designated as Accounting Standards Updates (ASU), with a year and assigned sequence number. The codification effort, while not creating or changing accounting rules, changed how users would cite accounting regulations. Citations in financial statements must identify the sections within the new codification. The codification is effective for interim and annual periods ending after September 15, 2009. The Company is complying with the new codification standards.  The interim condensed financial statements were prepared in accordance with U.S. generally accepted accounting principles (GAAP) and with the instructions for quarterly reports on Form 10-Q and Regulations S-X and S-K. The interim condensed financial statements reflect all normal, recurring adjustments and accruals that are, in the opinion of management, necessary for a fair presentation of financial position and results of operations for the interim periods presented. Interim financial statements do not include all of the information and notes required by GAAP for audited annual financial statements. These financial statements should be read in conjunction with the financial statements and notes thereto included in the Companys Annual Report on Form 10-K for the year ended December 31, 2008. Certain reclassifications were made to prior-period financial statements to conform with the current presentation.  The preparation of the condensed financial statements and notes in conformity with GAAP requires that management make estimates and assumptions that affect the amounts of revenues, expenses, assets and liabilities and disclosure of contingent assets and liabilities. Actual results could differ from estimates. The results of operations for the three, nine and twelve months ended September 30, 2009, are not necessarily indicative of the results that may be expected for the year ending December 31, 2009.  All dollar amounts in this quarterly report on Form 10-Q are in millions, except where otherwise noted.  The condensed financial statements reflect management's consideration of known subsequent events as of November 9, 2009, the date that the condensed financial statements were issued.  Note 3  Fair-Value Measure  In April 2009, the FASB issued guidance requiring disclosures about fair value of financial instruments for interim periods as well as in annual financial statements. The new disclosure rules are effective for interim reporting periods ending after June 15, 2009. The following table discloses the fair value and related carrying amount of certain financial instruments not disclosed in other notes to the condensed financial statements in this quarterly report on Form 10-Q:  CarryingEstimatedCarryingEstimatedAmountFair ValueAmountFair ValueSept. 30, 2009Dec. 31, 2008(in millions)Financial assetsCash and cash equivalents$    1.2$    1.2

Long-term debt  the fair value of fixed-rate debt is based on the discounted present value of cash flows using the Company's current borrowing rates.   ITEM 2. MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.  The following discussion updates information as to Questar Gass financial condition provided in its previous Form 10-K filing, and analyzes the changes in the results of operations between the three-, nine- and twelve-month periods ended September 30, 2009 and 2008. For definitions of commonly used terms found in this Form 10-Q, please refer to the Glossary of Commonly Used Terms provided in the Companys 2008 Form 10-K.  RESULTS OF OPERATIONS  Questar Gas, which provides retail natural gas distribution services in Utah, Wyoming and Idaho, reported a seasonal net loss of $8.1 million in the third quarter of 2009, compared with a loss of $8.8 million in the third quarter of 2008. Net income was $21.7 million in the first nine months of 2009, up 10% from $19.8 million in the first nine months of 2008. Net income for the 12 months ended September 30, 2009, was $42.1 million compared with $37.7 million in the 12 months ended September 30, 2008.

Customer growth increased the margin by $0.3 million in the third quarter of 2009 and $1.5 million in the first nine months of 2009 and $2.2 million in the 12 months ended September 30, 2009.  A change in general rates went into effect in mid-August 2008 and increased the margin by $0.4 million in the third quarter of 2009, $6.7 million in the first nine months of 2009 and $10.1 million in the 12 months ended September 30. Questar Gas's allowed return on equity is 10% in Utah and 10.5% in Wyoming.  Temperature-adjusted usage per customer increased 5% in the third quarter of 2009 compared to the third quarter of 2008, decreased 1% in the first nine months of 2009 compared to the first nine months of 2008 and decreased 2% in the 12 months ended September 30, 2009 compared to the 12 months ended September 30, 2008. The impact on the company margin from changes in usage per customer has been mitigated by a pilot conservation-enabling tariff (CET) that was approved by the PSCU beginning 2006. The CET resulted in a margin increase of $0.7 million in the first nine months of 2009, partially offsetting the $1.4 million decrease in margin resulting from lower usage per customer. The decrease in usage per customer in the 12 months ended September 30, 2009 was recovered through the general rate case.


Questar Gas 2009 Form 10-Q 8


Weather, as measured in degree days, was 58% warmer than normal in the third quarter of 2009 and 2% warmer than normal in the first nine months of 2009. Weather for the 12 months ended September 30, 2009, was 2% warmer than normal compared to 10% colder than normal for the 12 months ended September 30, 2008. A weather-normalization adjustment on customer bills generally offsets financial impacts of moderate temperature variations.  Expenses Cost of natural gas sold was down 42% in the third quarter of 2009 compared to the third quarter of 2008 and down 13% in the first nine months of 2009 compared to the first nine months of 2008. The decreases were due to lower gas purchase expenses per dth and lower sales volumes. Cost of natural gas sold during the 12 months ended September 30, 2009 was 4% lower than the year-earlier period because of a 9% reduction in sales volumes partially offset by higher gas purchase expenses per dth. Questar Gas accounts for purchased-gas costs in accordance with procedures authorized by the PSCU and the PSCW. Purchased-gas costs that are different from those provided for in present rates are accumulated and recovered or credited through future rate changes. As of September 30, 2009, Questar Gas had a $37.1 million over-collected balance in the purchased-gas adjustment account representing costs recovered from customers in excess of costs incurred. Questar Gas reduced its rates for gas costs by an annualized $165 million effective March 1, 2009. In addition, Questar Gas rebated approximately $50 million of the over-collected balance in the purchased-gas adjustment account to customers in May 2009 business. Rates for gas costs were reduced by an additional $34 million beginning October 2009.  Operating and maintenance expenses decreased 16% in the third quarter of 2009 compared to the third quarter of 2008, increased 14% in the first nine months of 2009 compared to the first nine months of 2008 and increased 20% in the twelve months ended September 30, 2009, compared to the same period in 2008. Demand-side management costs increased $0.7 million in the third quarter of 2009 over the third quarter of 2008, $9.1 million in the first nine months of 2009 over the first nine months of 2008 and $12.8 million in the 12 months ended September 30, 2009, over the 12 months ended September 30, 2008. These costs are for the company's energy-efficiency program and are recovered from customers through periodic pass-through rate changes. Bad debt costs were $2.3 million lower in the third quarter of 2009 compared to the third quarter of 2008 and $2.0 million lower in the first nine months of 2009 compared to the first nine months of 2008. General and administrative expenses increased 26% in the 2009 third quarter, increased 7% in the first nine months of 2009 and decreased 5% in the 12 months ended September 30, 2009. Operating, maintenance, general and administrative expenses per customer were $114 in the first nine months of 2009 compared to $103 in the first nine months of 2008 due to an increase in demand-side management cost of $10 per customer.  Depreciation expense increased 6% in the third quarter of 2009, first nine months of 2009 and the 12 months ended September 30, 2009, respectively compared to the 2008 periods, primarily as a result of plant additions from customer growth and system expansion.  Forward-Looking Statements This quarterly report may contain or incorporate by reference information that includes or is based upon forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements give expectations or forecasts of future events. You can identify these statements by the fact that they do not relate strictly to historical or current facts. They use words such as anticipate, estimate, expect, project, intend, plan, believe, and other words and terms of similar meaning in connection with a discussion of future operating or financial performance. In particular, these include statements relating to future actions, prospective services or products, future performance or results of current and anticipated services or products, exploration efforts, expenses, the outcome of contingencies such as legal proceedings, trends in operations and financial results.  Any or all forward-looking statements may turn out to be wrong. They can be affected by inaccurate assumptions or by known or unknown risks and uncertainties. Many such factors will be important in determining actual future results. These statements are based on current expectations and the current economic environment. They involve a number of risks and uncertainties that are difficult to predict. These statements are not guarantees of future performance. Actual results could differ materially from those expressed or implied in the forward-looking statements. Among factors that could cause actual results to differ materially are:  · the risk factors discussed in Part I, Item 1A of the Companys Annual Report on Form 10-K for the year ended December 31, 2008;


Questar Gas 2009 Form 10-Q 9


· general economic conditions, including the performance of financial markets and interest rates; · changes in industry trends; · changes in laws or regulations; and · other factors, most of which are beyond the Companys control.  Questar Gas undertakes no obligation to publicly correct or update the forward-looking statements in this quarterly report, in other documents, or on the Web site to reflect future events or circumstances. All such statements are expressly qualified by this cautionary statement.   ITEM 4.  CONTROLS AND PROCEDURES.  Evaluation of Disclosure Controls and Procedures. The Companys Chief Executive Officer and Chief Financial Officer have evaluated the effectiveness of the Companys disclosure controls and procedures (as such term is defined in Rules 13a-15(e) under the Securities Exchange Act of 1934, as amended) as of September 30, 2009. Based on such evaluation, such officers have concluded that, as of September 30, 2009, the Companys disclosure controls and procedures are effective in alerting them on a timely basis to material information relating to the Company, required to be included in the Companys reports filed or submitted under the Exchange Act. The Companys Chief Executive Officer and Chief Financial Officer also concluded that the controls and procedures were effective in ensuring that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Companys management including its principal executive and financial officers or persons performing similar functions as appropriate to allow timely decisions regarding required disclosure.  Changes in Internal Controls. There were no changes in the Companys internal controls over financial reporting that occurred during the quarter ended September 30, 2009, that have materially affected, or are reasonably likely to materially affect, the Companys internal control over financial reporting.    PART II.  OTHER INFORMATION  ITEM 1.  LEGAL PROCEEDINGS.  Questar is involved in various commercial and regulatory claims and litigation and other legal proceedings that arise in the ordinary course of its business. Management does not believe any of them will have a material adverse effect on the Companys financial position, results of operations or cash flows. A liability is recorded for a loss contingency when its occurrence is probable and damages can be reasonably estimated based on the anticipated most likely outcome. Disclosures are provided for contingencies reasonably likely to occur which would have a material adverse effect on the Companys financial position, results of operations or cash flows. Some of the claims involve highly complex issues relating to liability, damages and other matters subject to substantial uncertainties and, therefore, the probability of liability or an estimate of loss cannot be reasonably determined.  In United States ex rel. Grynberg v. Questar Corp., Civil No. 99-MD-1604, consolidated as In re Natural Gas Royalties Qui Tam Litigation, Consolidated Case MDL No. 1293 (D. Wyo.), Jack Grynberg filed claims against Questar and other natural gas companies under the federal False Claims Act (Act) alleging industry-wide mismeasurement of natural gas quantities on which federal royalty payments are made. The trial court dismissed the case on jurisdictional grounds because Grynberg was not the original source of information for the alleged mismeasurement as required by the Act. The 10th Circuit Court of Appeals affirmed the dismissal in March 2009. On October 5, 2009, the U.S. Supreme Court denied Grynbergs petition for certiorari which concludes the matter.    ITEM 6.
