Report of Independent Auditors

Participants in Questar Corporation
Employee Investment Plan

We have audited the accompanying statements of net assets
available for plan benefits of Questar Corporation Employee
Investment Plan as of December 31, 1997 and 1996, and the
related statements of changes in net assets available for plan
benefits for the years then ended. These financial statements
are the responsibility of the Plan's management. Our
responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted
auditing standards. Those standards require that we plan and
perform our audit to obtain reasonable assurance about whether
the financial statements are free of material misstatement.  An
audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An
audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating
the overall financial statement presentation.  We believe that
our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above
present fairly, in all material respects, the net assets
available for plan benefits of the Plan at December 31, 1997 and
1996, and the changes in its net assets available for plan
benefits for the years then ended, in conformity with generally
accepted accounting principles.

Our audits were made for the purpose of forming an opinion on
the financial statements taken as a whole.  The accompanying
supplemental schedules are presented for the purposes of
complying with the Department of Labor's Rules and Regulation
for Reporting and Disclosure under the Employee Retirement
Income Security Act of 1974, and are not a required part of the
financial statements.  The supplemental schedules have been
subjected to the auditing procedures applied in our audit of the
1997 financial statements and, in our opinion, are fairly stated
in all material respects in relation to the 1997 financial
statements taken as a whole.

Questar Corporation
Employee Investment Plan

Notes To Financial Statements

December 31, 1997


1.  Description of the Plan

The Questar Corporation Employee Investment Plan (Plan) is a
defined contribution plan for employees of Questar Corporation
and its subsidiaries (Questar).  The Plan is an employee stock
ownership plan (ESOP) as defined in Code Section 4975(e)(7).

In addition to Questar common stock, employees are able to
direct the investment of their contributions into the following
funds: the 1) Merrill Lynch Retirement Preservation Trust
(replacing the Equitable GIC and Fidelity Money Market Fund
effective July 1997), which invests primarily in a broadly
diversified portfolio of Guaranteed Investment Contracts (GICs)
and in obligations of U.S. government and government-agency
securities;  2) Fidelity Magellan Fund, which invests primarily
in common stocks; 3) Fidelity Puritan Fund, which invests
primarily in common stocks and bonds; 4) Fidelity Intermediate
Bond Fund, which invests primarily in high and upper-medium
grade fixed-income obligations; 5) Vanguard 500 Portfolio Index
Fund, which invests primarily in common stocks as it seeks to
replicate the Standard & Poor's 500 Composite Price Index; and
6) Vanguard Total International Portfolio Fund, which invests in
a combination of the European, Pacific, and Emerging Markets
Vanguard International Equity Index Funds.  The Plan allows
participants to change their contribution elections one day
before the first day of the calendar month in which the change
is to become effective.

With the exception of the Questar stock fund, participants can
transfer amounts invested between the various investment funds
on a monthly basis.  Employees who contribute to the stock fund
or any of the other investment funds receive employer matching
contributions in the form of leveraged Questar shares released
from the suspense account (Note 3) on up to 6% of their eligible
compensation contributed, at the following percentages:  100% of
the first 2%, 75% of the next 2%, and 50% of the next 2%.

Employees are eligible to participate in the Plan after
completing one year of service.  An employee is credited with
one year of service for each year in which at least 1,000 hours
are worked or paid for by Questar or an affiliate.  Subject to
certain restrictions in the Internal Revenue Code (Code),
non-highly compensated employees can elect to contribute from 1%
to 16% of annual compensation to the Plan on either a pre-tax
basis pursuant to salary reduction arrangements, that will
qualify the contributions under  section  401(k)  of  the code,
on an  after-tax basis, or a combination of the two. Highly
compensated employees"are limited to contributing from 1% to 6%
of annual compensation to the Plan on a pre-tax basis, after-tax
basis, or a combination of the two.

The Plan also provides an additional $200 annual employer
contribution at the end of the Plan year in the form of shares
of Questar stock to each employee eligible to participate in the
Plan at the beginning of the Plan year and employed on the last
day of the Plan year.  This contribution is made irrespective of
whether the eligible employee actually participates in the Plan.

The Plan provides for the direct rollover of taxable amounts
withdrawn from the Plan to the Trustee of the participant's
Individual Retirement Account (IRA) or other qualified plan, if
the participant so elects.

The rules for in-service withdrawals of Questar shares and
investment funds allocated to participants' accounts and for
distributions of such amounts upon termination of employment,
disability or death are set forth in the Summary Plan
Description of the Plan.

The Plan is subject to the diversification requirements imposed
on ESOP's by the Tax Reform Act of 1986 and meets these
requirements by allowing qualified participants to receive
distributions of shares of Questar stock.

Employees are always fully vested in all shares and funds
allocated to their individual accounts.  Should the Plan
terminate at some future time, all amounts allocated to the
employees' accounts would be distributed to them.


2.  Accounting Policies

The preparation of financial statements in conformity with
generally accepted accounting principles requires management to
make estimates and assumptions that affect the amounts reported
in the financial statements and accompanying notes.  Actual
amounts could differ from the estimates.

Investments

Investment in Questar common stock is recorded at market value
based on the closing market price on the last business day of
the year on the  New  York  Stock  Exchange.   The mutual funds
are valued at market.  The Merrill Lynch Retirement Preservation
Trust is valued at cost plus interest earned, which approximates
market.  Short-term investments consist primarily of investments
in a separate money market portfolio fund and are valued at
market.

Dividends

Questar has a Dividend Reinvestment and Stock Purchase Plan
whereby participants may reinvest dividends to purchase
additional shares of Questar common stock at market value.
Dividends payable with respect to Questar stock purchased with
employee after-tax and 401(k) contributions are distributed
directly to participants unless they elect to have such
dividends retained in the Plan.  Dividends on shares purchased
with employer contributions must be reinvested.  Dividends paid
on leveraged shares are applied to the principal and interest
payments on the promissory note payable to Questar (Note 3).

Withdrawals

Withdrawals are recorded based on market prices at the date
withdrawn.  The differences between cost and market at the time
of withdrawal are included in the financial statements as
realized gains or losses.

Administrative Expenses

Legal, accounting, and other administrative expenses except
commissions and a portion of the trustee fees have been paid by
Questar.

Income Taxes

The Plan is a qualified defined contribution plan under section
401(a) of the Code and is exempt from federal income tax.  The
Plan administrator is not aware of any course of action or
series of events that have occurred,  including Plan amendments
subsequent  to the latest determination letter, that might
adversely affect the Plan's qualified status. Participants are
not subject to income tax on employer contributions (including
401(k) salary reductions) or income credited to individual
accounts until such time as these amounts are distributed.  A
description of the income tax consequences to employees is
included in the Summary Plan Description of the Plan, which has
been provided to all participants.

3.  Security Acquisition Loans

In 1989 the Plan issued two promissory notes payable to Questar
totaling $35,000,000 and used the proceeds to purchase 1,992,884
shares (leveraged shares) of Questar common stock at $17.5625
per share.  These shares are held in a separate suspense account
established under the Trust and are released and allocated to
eligible participants as the notes are repaid over a ten-year
period.  Payments on the notes are made with contributions from
Questar and from dividends and earnings received on the
remaining allocated and unallocated leveraged shares. The notes
are collateralized by the unreleased leveraged shares.  The
8.25% Senior ESOP Notes-Series A matured and were redeemed on
July 1, 1996.  The remaining 8.28% Senior ESOP Notes-Series B
had an outstanding balance of $10,172,947 and $15,555,501 as of
December 31, 1997 and 1996, respectively.

Under the terms of the notes, the Plan is obligated to make
principal payments annually, which, in aggregate, must meet or
exceed cumulative minimum principal payments as of each payment
date.  The minimum principal payment requirements for the two
years following December 31, 1997, are $5,300,000 in 1998 and
$4,872,947 in 1999. Cumulative actual payments may exceed the
cumulative minimum payments when the actual number of shares
needed to make matching allocations exceeds the minimum shares
required to be released under the terms of the notes.  Leveraged
shares in excess of those needed to make matching allocations
may also be released from the suspense account in certain years
in order to meet required cumulative minimum payments.  These
excess shares will be allocated to: (i) participants who are
Questar employees on the last day of the year, (ii) participants
who are on leave under the federal Family and Medical Leave Act
of 1993 on the last day of such Plan year, and (iii) to former
participants (or their beneficiaries) who become disabled,
retire, or die during the year in which the excess leveraged
shares are released from the suspense account.  At year-end 1997
and 1996, a special distribution of excess shares was allocated
to the accounts of the eligible participants who contributed to
the Plan during the year. Depending on the market price of
Questar stock, there could be further special distributions of
shares in future years.

4. Investments

First Security Bank, N.A., is the Plan Trustee.  Investments in
common stock of Questar at cost for the two years ended December
31, 1997, were as follows:
