QUESTAR CORPORATION
PROXY STATEMENT

May 18, 1999


     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 
18, 1999, 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 2002.  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:   The election of Patrick J. Early, Marilyn J. Kite, Dixie L. 
Leavitt, and D. N. Rose to serve as directors

Q:   Who can vote?

A:   Stockholders who owned shares as of the close of business on 
March 22, 1999.  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.  The Company has not hired an 
independent proxy solicitor, but may use directors, officers, and 
employees to personally solicit proxies.

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 22, 1999, the Company had 82,876,168 shares of common 
stock.  A majority of the shares, or 41,438,085 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 22, 1999, 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 otherwise 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 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 19 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 2000 and included in the proxy statement, a 
stockholder proposal must be received at the Company's office no later 
than December 6, 1999.

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, Marilyn S. 
Kite, Dixie L. Leavitt, and D. N. Rose as the nominees for election to 
three-year terms that expire in May of 2002.  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 a 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 engaged in the same principal

its major operating subsidiaries.  All members are nonemployee 
directors.

     Nominating: Recommends individuals for nomination to the Board of 
Directors.  Will consider director candidates suggested by 
shareholders, but hasn't established formal procedure.

     Executive: May act on behalf of the Board of Directors.

Attendance at Board and Committee Meetings

     The Company's Board of Directors held four regular meetings 
during 1998; Board Committees held a total of six meetings.  All 
directors attended at least 75 percent of the meetings.  The Company's 
directors had an overall attendance percentage of 98 percent.    

Directors' Compensation

     The Company's nonemployee directors receive the following 
compensation for their service as directors:

        Annual Retainer          $14,400 (monthly installments of $1,200)
        Board Meeting Fee        $900
        Committee Meeting Fee:   $700 ($900 for Chairmen)

Directors also receive annual retainer fees of $4,800 (monthly 
installments of $400) and meeting fees of $600 for service as 
directors of the Company's primary subsidiaries.

     Nonemployee directors can also defer the receipt of their fees 
and have such deferred fees earn interest as if invested in long-term 
certificates of deposit or be accounted for with "phantom shares" of 
the Company's common stock.

     Nonemployee directors also receive annual grants of nonqualified 
stock options at the first regular meeting of the Board of Directors.  
On February 9, 1999, such eligible directors, with the exception of 
Messrs. Garrison, Michael, and Simmons, received a stock option to 
purchase 6,400 shares.  The three 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 the date of grant, which was $17.00.

     Nonemployee directors can elect to receive their fees in shares 
of stock.  The plan for payment of fees in stock and the stock option 
plan have both been approved by the Company's shareholders.

     The Company has entered into individual indemnification 
agreements with all directors, including Messrs. Cash, Nordloh, and 
Rose, indemnifying them as directors.  The form of these agreements 
was approved by the Company's stockholders at the 1988 Annual Meeting.

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.  

Certain Relationships and Related Transactions

     Mr. Garrison is the former Chairman, President and Chief 
Executive Officer of Cordant Technologies.  Cordant Technologies

$1,708,853 during 1998 for gas supplies.

     Mr. Parker serves as a member of the Board of Trustees of

employees under the Company's health plan.  In 1998, the Company and 
its subsidiaries paid IHC a total sum of $629,473 in administrative 
fees.

     Mr. Kadlec is the former President and Chief Executive Officer of 
BC Gas Inc.  BC Gas has contracts with Questar Energy for the purchase

$7,098,811 for gas sales and was billed $2,799,767 for gas deliveries 
from BC Gas.  BC Gas also has long-term contracts with Questar 
Pipeline for storage service and paid $2,522,324 for such service 
during 1998.

     Mr. Simmons is the Chairman of the Board of Zions First National 
Bank.  The Company has a line of credit through Zions.  Two of the 
Company's subsidiaries, Questar InfoComm, Inc. and Questar Gas 
Company, have accounts with Zions.  The Company's credit line with 
Zions is priced at the same competitive range paid by the Company for 
other lines of credit, and the services provided by Zions to Questar 
InfoComm and Questar Gas are based on commercial terms that are 
available to other clients.  A Zions' affiliate also leases space from 
a business continuity center owned by Questar InfoComm at the same 
rates charged other customers.

Corporation Educational Foundation and the Questar Corporation Arts 
Foundation, two nonprofit corporations that own an aggregate of

     1These stock options vest in four annual, equal installments, 
with the first installment exercisable as of August 10, 1998.  
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 12 months following a 
participant's death or disability.   Options may be exercised after 
retirement for terms specified in advance by the Committee.

     2 When calculating the present value of options as of the date 
granted (February 10, 1998), the Company used the Black-Scholes option 
pricing model.  The Company assumed a volatility of 20.2 percent, a 
risk-free interest rate of 5.50 percent, a dividend yield of 3.09 
percent, and an average life of 4.40 years.  The real value of the 
options in this table depends upon the actual performance of the 
Company's stock during the applicable period.  There can be no 
assurance that the values shown in this table will be achieved.

     The following table lists information concerning the stock 
options that were exercised by  the named executive officers during 
1998 and the total options and their value held by each at year-end 
1998.

     1All option numbers reflect the Company's two-for-one stock split 
in June of 1998.

     2The "value" is calculated by subtracting the fair market value 
of the shares purchased on the date of exercise minus the option 
price.  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, 1998, 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 1998, do not include Social 
Security benefits, and reflect a 50% 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, under the Retirement Plan, 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 for 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.  All of the 
officers listed in the table earn annual compensation in excess of the 
current cap of $160,000 and all of them have vested benefits under the 
SERP.

     Information concerning each named executive officer's 
compensation, final average earnings, and years of service as of 
December 31, 1998 is shown below:

S. E. Parks         205,105               186,483           24.4

Each officer's 1998 compensation for purpose of the Retirement Plan is 
different than shown on the table because the former includes cash 
payments when made, not when earned, and the value of restricted stock 
when distributed, not granted.

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 
compensation equal to up to two years' salary 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: 
$1,000,000 to Mr. Cash; $607,800 to Mr. Rose: $590,000 to Mr. Nordloh; 
$491,600 to Mr. Heiner; and $375,000 to Mr. Parks.  The Company's 
executive officers would also receive certain supplemental retirement 
benefits, welfare plan benefits, and cash bonuses.

     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 15 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., a 
peer group of nine diversified natural gas companies selected by the 
Company, and of the S&P Composite-500 Stock Index.  The Company 
believes performance of the nine 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 nine peer companies are Columbia Energy Group, Consolidated 
Natural Gas, Energen, Equitable Resources, KN Energy, MCN Corporation, 
National Fuel Gas, ONEOK, and Southwestern Energy.)

For 1998, the Company had a return of -10.2% compared to a return of 
28.4% for the S&P Index and a return of 3.4% for the ValueLine group 
and -12.5 for the Questar peer group.  For the five-year period, the 
Company had a compound annual return of 6.9% compared to returns of 
24.1% for the S&P 500 Index, 16.8% for the ValueLine Index and 11.0%

COMMITTEE REPORT ON EXECUTIVE COMPENSATION

     The Management Performance Committee (Committee) is a Committee 
of outside directors that is chaired by Gary G. Michael.  Other 
members include Patrick J. Early, U. Edwin Garrison,  W. Whitley 
Hawkins, Robert E. Kadlec, and Scott S. Parker.  This Committee 
reviews and approves all elements of the total compensation program 
for officers of the Company and administers the Company's Long-Term 
Stock Incentive Plan.  The Committee monitors the Company's executive 
compensation programs to verify that they are aligned with the 
Company's business strategies and financial goals.  The Committee 
believes 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.  The Committee believes 
that the total compensation earned by the Company's officers in 1998 
achieves these objectives and is fair and reasonable. 

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

     The Committee also assesses the individual performance of 
officers, particularly the performance of R. D. Cash and a group that 
includes the other named executive officers listed in the Summary 
Compensation Table.  The Committee periodically directs 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

     The Committee reviews 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.  The increases 
historically awarded to Mr. Cash and other officers are 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 1998 are listed in the table shown 
on page 10. 

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, the Committee reviews and 
approves 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 the Committee reviews 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.  The Committee determines the allocation of 
each officer's target bonus between business unit results and 
consolidated results.  As a general rule, one-half of each officer's 
earned bonus is paid in cash; the remainder is paid in shares of 
restricted stock that vest in two annual, equal installments.

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, the Committee uses the prior year's grant as the 
basis for determining each subsequent year's grant, but does change 
the size of grants when participants are promoted to new positions or 
when surveys indicate that stock options should be adjusted.  The 
Committee increased the size of options granted to the Company's 
highest ranking officers in 1998 after receiving a consultant's report 
that the option grants were not competitive, but did not increase them 
to the levels recommended by the consultant.  These grants are awarded 
pursuant to the terms of an omnibus Long-Term Stock Incentive Plan, 
which allows the Committee broad flexibility to use a wide range of 
stock-based performance awards.

     Stock options, from the Committee's 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.

     The Committee has 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 1998 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 individual members of the group when exercising stock options 
in 1998 and the year-end value of their remaining stock options.

Specific Compensation Decisions

     The Company's consolidated 1998 performance is a direct result of 
lower commodity prices, particularly crude oil.  The Company's stock 
price, in common with the stock prices of other integrated energy 
companies, has also been negatively affected.  The Committee, after 
considering 1998 performance results, did not increase the 1999 
salaries for Messrs. Cash and Nordloh, the individuals primarily 
responsible for the performance of the Market Resources unit.  Since 
the Committee believes that the Company's executive officers should 
continue efforts to achieve shareholder value and should be brought to 
the level of the stock options recommended by the Committee's 
consultant in 1998, the Committee increased the size of the options 
granted to Messrs.  Cash, Nordloh, and Rose.  In February of 1999, the 
Committee awarded Mr. Cash an option to purchase 140,000 shares at a 
price of $17.00 per share, compared to his 1998 option grant of 
130,000 shares.  The 1999 stock options vest in four equal annual 
installments beginning August 9, 1999.

Miscellaneous

     The Committee supports 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, the Committee 
supports 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.  The Company's Long-Term Stock Incentive Plan  
qualifies for performance-based compensation.  Consequently, the 
Company can continue to take a deduction for any ordinary income 
recognized by officers when exercising nonqualified stock options.  As 
is shown on the Summary Compensation Table, the annual compensation 
earned by Mr. Cash, the Company's highest paid officer, is 
significantly below the $1 million limit.

INDEPENDENT AUDITORS

     The firm of Ernst & Young LLP, independent auditors, has audited 
the accounts of the Company for a number of years, including 1998, and 
is expected to continue doing so.  Representatives of Ernst & Young 
LLP 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.

ANNUAL REPORT AND FORM 10-K REPORT

     An annual report for the year ending December 31, 1998, 
containing financial and other information about the Company, has been 
recently mailed to all stockholders of record.

Report on Form 10-K (excluding exhibits), as filed with the Securities 
and Exchange Commission, to any stockholder upon written 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.

     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.

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 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 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
