                                 PROXY STATEMENT

                                  May 21, 2002

     This Proxy Statement is being furnished to stockholders of Questar
Corporation, a Utah corporation, in connection with the solicitation of proxies
by the Board of Directors of the Company for use at the Annual Meeting of
Stockholders to be held on Tuesday, May 21, 2002, at 10:00 a.m., local time, and
any adjournment or postponement of such meeting. At the Annual Meeting, holders
of common stock will elect four directors of the Company for three-year terms
that expire in May of 2005. Information concerning the Annual Meeting and
solicitation of proxies for it is presented in a question and answer format.

Q:   What am I voting on?

A:   You can cast your votes to elect four nominees to serve new three-year
     terms. The nominees include three incumbent directors--Pactrick J. Early,
     James A. Harmon, and D.N.Rose--and L. Richard Flury who does not currently
     serve on the Board. (Mr. Dixie L. Leavitt has reached mandatory retirement
     age and has not been renominated for election since he is retiring in May.)

Q:   Who can vote?

A:   Stockholders who owned shares as of the close of business on
     March 25, 2002. Each holder is entitled to one vote for each share held on
     such date.

Q:   How do I vote?

A:   Sign and date each proxy card you receive and return it in the enclosed
     prepaid envelope. If you return your signed proxy card, but do not indicate
     how you want to vote, your shares will be voted for the named nominees. You
     have the right to revoke your proxy by notifying the Company's Corporate
     Secretary prior to the meeting, by returning a later dated proxy, or by
     voting in person at the Annual Meeting.

     If you own shares through a broker or other nominee, you must return your
     proxy card to the broker. Your votes cannot be counted if you send the
     proxy directly to the Company.

Q:   What does it mean if I get more than one proxy card?

A:   It means that you hold shares registered in more than one account. Sign and
     return all proxies to make sure that all your votes are counted, but
     consider consolidating your accounts to minimize the administrative cost of
     sending materials to you.

Q:   Who is soliciting my proxy?



A:   Questar's Board of Directors.

Q:   Who is paying for the solicitation?

A:   The Company is paying for the solicitation of proxies and will reimburse
     banks, brokers, and other custodians for reasonable charges to forward
     proxy materials to beneficial holders.

Q:   What constitutes a quorum?

A:   On March 25, 2002, the Company had 81,641,571 shares of common stock. A
     majority of the shares, or 40,820,786 shares, constitutes a quorum. Once a
     quorum is present, the nominees will be elected upon receiving a plurality
     of the shares represented at the meeting. The Company's Bylaws provide that
     votes "withheld" from nominees will not be counted for purposes of
     determining whether a nominee receives a plurality of votes. Shares
     registered in the names of brokers for which proxies are voted for some but
     not all matters will be considered as voted only as to those matters
     actually voted. Abstentions, broker nonvotes, and instructions to withhold
     authority to vote for one or more of the nominees will result in such
     nominees receiving fewer votes. Such action, however, will not reduce the
     number of votes otherwise received by the nominee.

Q:   Who can attend the Annual Meeting?

A:   Any stockholder of record as of March 25, 2002, can attend. If you own
     shares through a nominee or trustee, please obtain a letter, account
     statement, or other evidence of your ownership of shares as of such date.

Q:   How will my vote be handled on other matters?

A:   Questar's Bylaws limit the matters presented at an Annual Meeting to those
     in the notice, those properly presented by the Board of Directors and those
     presented by stockholders so long as the stockholder gives the Corporate
     Secretary written notice of the matter at least 90 days but not more than
     120 days before the meeting. We do not expect any other matter to come
     before the meeting. If any other matter is presented at the Annual Meeting,
     your signed proxy gives the named proxies authority to vote your shares.
     (See "Other Matters" on page 21 for a detailed discussion of the Company's
     Bylaw requirements.)

Q:   When are stockholder proposals due for the next Annual Meeting?

A:   To be considered for presentation at the Company's Annual Meeting scheduled
     for May of 2003 and included in the proxy statement, a stockholder proposal
     must be received at the Company's office no later than December 9, 2002.

                              ELECTION OF DIRECTORS

     The Company's Restated Articles of Incorporation provide for a board of 13
directors, divided into three classes, approximately equal in number, elected to
serve three-year terms.

     The Board of Directors has selected Patrick J. Early, L. Richard Flury,
James A. Harmon, and D. N. Rose as the nominees for election to three-year terms
that expire in May of 2005. Unless you give other instructions for your shares,
the proxies will be voted for the nominees.

     Each of the nominees has consented to serve for the new term. However, in
the event that any nominee is unwilling or unable to serve as a director, the
proxies named in the enclosed proxy may vote, in their discretion, for any other
person.

     Biographical information concerning the nominees and the current directors
of the Company whose terms will continue after the Annual Meeting is set forth
on the following pages. Unless otherwise indicated, the nominees have been

options at the first regular meeting of the Board of Directors. On February 11,
2002, eligible directors, with the exception of Messrs. Early, Hawkins, Kadlec,
and Michael, each received a stock option to purchase 6,400 shares. The four
named directors each received a stock option to purchase 8,000 shares,
reflecting added responsibilities as Chairmen of Board Committees. The options
are priced at the closing price on February 11, 2002, which was $22.95.

     Nonemployee directors can elect to receive their fees in shares of stock.
The plan for providing payment of fees in stock and the stock option plan have

directors, including Messrs. Cash, Nordloh, Rattie, and Rose, indemnifying them
as directors. The form of these agreements has been approved by the Company's
stockholders.

DIRECTORS' RETIREMENT POLICY

     In May of 1992, the Board of Directors adopted a retirement policy that
permits an outside director to continue serving in such position until the
annual meeting following his 72nd birthday if still actively engaged in
business, financial, and community affairs. With the exception of the Company's
Chief Executive Officer, any inside director is expected to resign as a director
on or before the date of his retirement as an employee.

     (1) These stock options vest in four annual, equal installments, with the
first installment exercisable as of August 1, 2001 (Mr. Rattie's special option)
and August 13, 2001 (all other options). Participants can use cash or
previously-owned shares as consideration for option shares. Options expire when
a participant terminates his employment, unless termination is caused by an
approved retirement, death, or disability. Options can be exercised within 12
months following a participant's death or disability. Options may be exercised
after retirement for terms specified in the terms of the individual option
agreements.

     (2) When calculating the present value of options as of the dates granted
(February 1, 2001 and February 13, 2001), the Company used the Black-Scholes
option pricing model. The Company assumed a volatility of 30.7 percent, a
risk-free interest rate of 5.02 percent, a dividend yield of 2.52 percent, and
an average life of 7.0 years.

     (1) The "value" is calculated by subtracting the fair market value of the
shares purchased on the date of exercise minus the option price. This table does
not reflect any taxes paid by the named executives as a result of exercising
options or selling all or any portion of the shares obtained as a result of
exercising options. The current value of the shares may be higher or lower than
the aggregate value reported in the table.

RETIREMENT PLANS

     The Company maintains a noncontributory retirement plan that is funded
actuarially and does not involve specific contributions for any one individual.
The following table lists the estimated annual benefits payable on a straight
line annuity basis under the Company's Retirement Plan as of December 31, 2001,
and, if necessary, the Company's Supplemental Executive Retirement Plan (SERP).
The benefits shown are based on earnings and years of service for an employee
reaching normal retirement age of 65 in 2001, do not include Social Security
benefits, and reflect a 50 percent surviving spouse benefit. Benefits under the
Retirement Plan are not reduced or offset by Social Security benefits, although
participants who retire prior to age 62 do receive a temporary supplement until
reaching age 62.

     The Company's Retirement Plan has a "step rate/excess" benefit formula. The
formula provides for a basic benefit that is calculated by multiplying the
employee's final average earnings by a specified basic benefit factor and by
subsequently multiplying such sum by the employee's years of service (to a
maximum of 25). This basic benefit is increased for each year of service in
excess of 25 and is reduced for retirement prior to age 62. Employees also
receive a permanent supplemental benefit that is calculated by multiplying the
difference between the employee's final average earnings and his "covered
compensation" by a supplemental factor that varies by age. (The term "covered
compensation" refers to the 35-year average Social Security wage base tied to
year of an employee's birth.) Employees who retire prior to age 62 also receive
a temporary supplement that is tied to years of service until they are eligible
to receive Social Security benefits at age 62.

     Federal tax laws impose limits on the amount of a participant's annual
compensation that can be used when calculating benefits under qualified plans
and on the amount of benefits that can be paid to a participant from such plans.
The SERP, a nonqualified plan, was adopted in 1987 to compensate officers who
are affected by these limits. It provides retirement benefits equal to the
difference between the benefits payable under the qualified Retirement Plan and
the benefits that would be payable absent such limits. The SERP also permits
participants to make advance elections to receive lump-sum payments. With the
exception of Mr. Rattie, all of the officers listed in the table have vested
benefits under the SERP; all of the listed officers earn annual compensation in
excess of the current (2002) cap of $200,000.

     Information concerning each named executive officer's compensation, final
average earnings, and years of service as of December 31, 2001 is shown below:

Each officer's 2001 compensation for purpose of the Company's retirement plans
is different than shown on the table because the former includes cash payments
when made, not when earned; the value of restricted stock when distributed, not
granted, and includes dividends paid on shares of restricted stock.

EXECUTIVE SEVERANCE COMPENSATION PLAN

     The Company has an Executive Severance Compensation Plan that covers the
Company's executive officers and all other officers of the Company and its
affiliated companies. Under this plan, participants, following a change in
control of the Company, are eligible to receive

                                       14


compensation equal to up to two years' salary, cash bonuses, and miscellaneous
benefits upon a termination of their employment (as defined in the plan).

     The dollar amounts payable to the Company's executive officers (based on
current salaries paid by the Company and its affiliates) in the event of a
change in control of the Company are as follows: $1,200,000 to Mr. Cash;
$835,000 to Mr. Rattie: $691,000 to Mr. Nordloh; $660,000 to Mr. Rose; and
$460,000 to Mr. Parks. The Company's executive officers would also receive cash
bonuses, supplemental retirement benefits, and welfare plan benefits.

     Under the plan, a "change in control" is defined to include any change in
control required to be reported under Item 6(e) of Schedule A of Regulation 14A
of the Securities Exchange Act of 1934, as amended. A change in control is also
deemed to occur once any acquiring person becomes the beneficial owner, directly
or indirectly, of securities representing 25 percent or more of the Company's
outstanding shares of common stock.

                       CUMULATIVE TOTAL SHAREHOLDER RETURN

     The following graph compares the cumulative total return of the Company's
common stock with the cumulative total returns of a group of diversified natural
gas companies published by Value Line, Inc., which is a peer group of six
diversified natural gas companies selected by the Company, and the
S&P Composite-500 Stock Index. The Company believes performance of the six peer
company group to be a better benchmark of performance due to the higher
concentration of commodity price exposure, relative size, and business mix of
such companies. (The six peer companies are Energen Corporation; Equitable
Resources, Inc.; Kinder Morgan, Inc.; National Fuel Gas Company; ONEOK, Inc.;
and Southwestern Energy Company. MCN Energy Group, Inc. is no longer in the
group since it merged with another entity.)

December 31, 1996 in the Company's common stock, the equities of peer companies,
and the S&P 500 Index. It also assumes all dividends are reinvested. For 2001,
the Company had a return of -14.4 compared to a return of -3.6 percent for the
Questar peer group, and a return of -11.9 percent for the S&P Index. For the
five-year period, the Company had a compound annual return of 9.9 percent
compared to returns of 15.3 percent for the Questar peer group and 10.7 percent
for the S&P 500 Index.

                   COMMITTEE REPORT ON EXECUTIVE COMPENSATION

     The Management Performance Committee (Committee) is a Committee of outside
directors that is chaired by Patrick J. Early. Our other members include Teresa
Beck, James A. Harmon, W. Whitley Hawkins, Robert E. Kadlec, and Gary G.
Michael. We review and approve all elements of the total compensation program
for officers of the Company and administer the Company's Long- term Stock
Incentive Plan. We monitor the Company's executive compensation programs to
verify that they are aligned with the Company's business strategies and
financial goals. We believe that such programs motivate the Company's officers
to acquire and retain appropriate levels of stock ownership and are competitive
with programs offered by the Company's peers. We determined that the total
compensation earned by the Company's officers in 2001 achieved these objectives
and is fair and reasonable.

     Each year, we review the performance of the Company on a consolidated basis
and the performance of the Company's major lines of business and compare such
performance to specified groups of peer companies.

     We also assess the individual performance of officers, particularly the
performance of R. D. Cash, Keith O. Rattie, and the other named executive
officers listed in the Summary Compensation Table. We periodically direct
outside consultants to perform an in-depth audit and analysis of the total
compensation paid to the Company's officers.

     The Company's total compensation program for officers includes base
salaries, annual bonuses, and stock options. The total program is designed to
attract, motivate, reward and retain the broad-based management talent required
to achieve corporate objectives and increase shareholder value. Each of these
components of the total program is discussed in greater detail below.

BASE SALARIES

     We review base salaries for the Company's officers on an annual basis. Such
salaries are generally pegged at or near the 50th percentile or market average
of survey data. We have historically awarded salary increases to Mr. Cash and
other officers based on an assessment of each officer's comparison with survey
data, responsibilities, experience and performance. The salaries earned by the
named executive officers during 2001 are listed in the table shown on page 11.

                                       16


ANNUAL BONUSES

     All Company officers, but particularly the five highest paid officers, have
a significant portion of their total compensation at risk. Annual bonuses are
directly linked to key financial and operating objectives for the major business
units and for the Company on a consolidated basis. Each year, we review and
approve annual specified performance objectives. Performance objectives are both
financial (e.g., net income, return on equity) and efficiency objectives (e.g.,
customer service rating, safety performance, finding costs, operating and
maintenance costs). The performance objectives are set after we review actual
results for the prior year and budgeted results for the year in question and are
generally higher than actual results for the prior year and expectations for the
current year.

     An overall performance factor is multiplied by each officer's target bonus
to determine his earned bonus. Each officer's target bonus is a percentage of
his base salary in effect at the time the target bonus is approved. We also
determine the allocation of each officer's target bonus between business unit
results and consolidated results. Beginning with the bonuses earned for 2001,
two- thirds of each officer's earned bonus is paid in cash; the remainder is
paid in shares of restricted stock that vest approximately a year after being
granted.

STOCK OPTIONS

     Annual grants of stock options are awarded to the Company's officers and
key employees as part of their "risk-based" compensation. As a general rule, we
use the prior year's grant as the basis for determining each subsequent year's
grant, but we do change the size of grants when participants are promoted to new
positions or when surveys indicate that stock options should be adjusted. These
grants are awarded pursuant to the terms of an omnibus Long-term Stock Incentive
Plan, which allows us broad flexibility to use a wide range of stock-based
performance awards.

     Stock options, from our perspective, focus attention on managing the
Company from a long- term investor's perspective and encourage officers to have
a significant, personal investment in the Company through stock ownership. Stock
options awarded to officers and key employees become valuable only as the
Company's performance is reflected in increased stock prices. Stock options
constitute the Company's only long-term incentive compensation program. Officers
are encouraged to retain their stock for long-term investment, rather than sell
option shares after purchasing them.

     We have established stock ownership guidelines for officers. (Phantom stock
units attributable to an officer's deferred compensation are included.) All of
the officers named in the Summary Compensation Table satisfy these guidelines,
which constitute a multiple of their base salaries.

     Information concerning the stock options granted to the Company's highest
ranking executive officers in 2001 is included in the table labeled
"Option/Grants in Last Fiscal Year." The table labeled "Option Exercises"
provides information concerning the value realized by the

                                       17


individual members of the group when exercising stock options in 2001 and the
year-end value of their remaining stock options.

SPECIFIC COMPENSATION DECISIONS

     The Company's consolidated 2001 performance reflects the success of its
nonregulated business segment that capitalized on higher commodity prices,
favorable drilling results, and improved amortization rates, particularly during
the first half of the year. The Company's regulated business segment performed
better in 2001 than in 2000, reflecting the effects of a late-2000 early
retirement program and improved throughput for pipeline operations. The bonuses
payable to the Company's officers, including Messrs. Cash and Rattie, reflect
the success achieved by the Company in 2001 during a volatile environment. Mr.
Cash's bonus payment of $600,000 for 2001 includes a discretionary bonus in
addition to his earned bonus.

     After serving as Chief Executive Officer since March 1, 1982, Mr. Cash will
resign from this position and retire as an employee effective May 1, 2002. He
will continue to serve as Chairman of the Board. Consistent with his decision to
retire, we did not increase his salary. In recognition of his 20 years of
service as Chief Executive Officer and given the critical role we are asking him
to play in the Company's transition to Mr. Rattie's leadership, we awarded Mr.
Cash an option to purchase 200,000 shares and we set his 2002 target bonus at 75
percent of his base salary.

     We also reviewed the achievements of Mr. Rattie during his first year of
service and supported the decision made by the full Board of Directors to name
him to serve as Chief Executive Officer when Mr. Cash retires. We increased his
salary from $400,000 to $417,500 effective March 1, 2002 and will consider a
further increase for him when he becomes Chief Executive Officer. We granted him
an option to purchase 140,000 shares, and we increased his target bonus to 65
percent of his pre-March 1, 2002 base salary or $260,000.

     We determined to change some of the benchmarks for 2002 performance goals
to focus participants' attention on total shareholder return, earnings per
share, and specific objectives.

MISCELLANEOUS

     We support the Company's historic philosophy that officers are not
fundamentally different than employees, but are paid more due to the nature of
their responsibilities, their experience, and the greater demands on their time.
Consequently, we support the Company's traditional practice of limiting the
perquisites granted to officers. Company officers do not have first-class travel
privileges, cars, country club memberships, supplemental welfare benefit plans,
executive dining room service, or personal use of the Company's airplane.

     Federal tax law precludes the Company from deducting compensation paid in
excess of $1 million per year to any named executive officer. Performance-based
compensation, however, is not subject to this deductibility limit. Awards under
the Company's Long-term Stock Incentive Plan qualify for performance-based
compensation. Consequently, the Company can continue to take a

                                       18


deduction for any ordinary income recognized by officers when exercising
nonqualified stock options. The Company's cash bonus plans do not qualify as
performance-based plans.

                              INDEPENDENT AUDITORS

     Ernst & Young L.L.P. ("Ernst & Young"), independent auditors, has audited
the accounts of the Company for a number of years, including 2001.
Representatives of Ernst & Young are expected to be present at the Annual
Meeting, will have an opportunity to make a statement if they desire, and will
be available to respond to questions.

AUDIT FEES

     Ernst & Young charged the Company $393,098 for professional services
rendered for auditing the Company's 2001 annual financial statements and
reviewing the Company's financial statements included in its Form 10-Q and Form
10 K/A Reports filed in 2001.

FINANCIAL INFORMATION SYSTEM DESIGN AND IMPLEMENTATION FEES

     Ernst & Young did not perform any professional services described in
Paragraph (c)(4)(ii) of Rule 2-01 of Regulation S-X during 2001.

ALL OTHER FEES

     Ernst & Young billed the Company $327,629 for services it rendered other
than those listed above during 2001. These services include audit related fees
of $46,000 for auditing the Company's employee benefit plans, $220,971 for
reviewing registration statements prepared by the Company and its subsidiaries,
$3,135 for reviewing tax returns filed by the Company's officers, and $57,523
for consulting activities relating to energy risk management and tax planning.

                             AUDIT COMMITTEE REPORT

     Our Committee has reviewed and discussed the Company's audited financial
statements for the year ended December 31, 2001. We have also discussed with
Ernst & Young , the Company's independent auditing firm, the matters required by
Codification of Statements on Auditing Standards No. 61.

                                       19


     We have also received the written disclosures and the letter from Ernst &
Young required by Independence Standards Board Statement No. 1, and we have
discussed with representatives of Ernst & Young its independence from the
Company. We have considered whether Ernst & Young's provision of services to
generate the miscellaneous fees listed above is compatible with maintaining its
independence. We have also discussed with the Company's officers and Ernst &
Young such other matters and received such assurances from them as we deemed
appropriate.

     Based on our review and discussions, we have recommended to the Company's
Board of Directors the inclusion of the audited financial statements in the
Company's Annual Report on Form 10-K for the year ended December 31, 2001.

     Our Committee originally adopted a Statement of Responsibilities in May of
1997 and revised it in February of 2000.

                       ANNUAL REPORT AND FORM 10-K REPORT

     Questar has recently mailed an annual report for 2001 to shareholders of
record. The Company does take advantage of the special "householding" rules
recently adopted by the Securities and Exchange Commission to mail single copies
of the annual report (not the proxy statement) to multiple security holders
sharing an address unless we have received contrary instructions from one or
more of the security holders. We will promptly send a separate copy of the
annual report to you if you live at a shared address that only received a single
copy. Please contact Connie C. Holbrook at 180 East 100 South, Salt Lake City,
Utah 84111, or 801-324-5202, if you want to receive a separate copy of the
annual report now or in the future or if you want to request that only one copy
of the annual report be sent to your address if you are currently receiving
multiple copies of it.

     We will also send you without charge a copy of our Annual Report on Form
10-K (excluding exhibits) that was filed with the Securities and Exchange
Commission. You can contact the person identified above to make the request.

                            SECTION 16(a) COMPLIANCE

     Pursuant to Section 16(a) of the Securities Exchange Act of 1934 and
regulations promulgated by the Securities and Exchange Commission, the Company's
directors, certain officers, and persons that own more than 10 percent of the
Company's stock, are required to file reports of ownership and changes in
ownership with the Commission and the New York Stock Exchange and to furnish the
Company with copies of all such reports they file.

                                       20


     Based solely on its review of copies of such reports received or written
representations for certain reporting persons, the Company believes that all
filing requirements were satisfied for 2001.

                                  OTHER MATTERS

     Pursuant to the Company's Bylaws, business must be properly brought before
an annual meeting in order to be considered by stockholders. The Bylaws specify
the procedure for stockholders to follow in order to bring business before an
annual meeting. A stockholder who wants to nominate a person for election as a
director must deliver a written notice, by certified mail, to the Company's
Secretary. Such notice must be received at least 90 days and not more than 120
days prior to the date of the meeting. The notice must set forth (1) the name,
address, and stock ownership of the person making the nominations; (2) the name,
age, business address, residential address, and principal occupation or
employment of each nominee; (3) the number of shares of the Company's stock
owned by each nominee; (4) a description of all arrangements and understandings
between the stockholder and nominee pursuant to which the nomination is made;
and (5) such other information concerning the nominee as would be required,
under the rules of the Securities and Exchange Commission, in a proxy statement
soliciting proxies for the election of the nominee. The notice must also include
the signed consent of the nominee to serve as a director if elected.

     The Company's Bylaws also require that any stockholder who is entitled to
vote at the annual meeting and who wants to submit a proposal at such meeting
without having it considered through the proxy materials, must deliver a written
notice of the proposal, by certified mail, to the Company's Secretary. Such
notice must be received at least 90 days and not more than 120 days prior to the
date of such meeting. The notice must set forth (1) a brief description of the
proposal; (2) the stockholder's name, address, and stock ownership; and (3) any
material interest of the stockholder in the proposal.

     If the written notice is not received by the date specified in the Bylaws,
the named proxies will have discretionary voting to deal with the nomination or
proposal. A copy of the Company Bylaws specifying the requirements will be
furnished to any stockholder upon written request to the Secretary.

                                               By Order of the
                                               Board of Directors
