Gentlemen:

          Re:  Questar Corporation
               Dividend Reinvestment and Stock Purchase Plan
               Registration Statement on Form S-3

     I am Vice President, Corporate Secretary, and Senior
Corporate Counsel of Questar Corporation, a Utah corporation (the
"Company").  In such capacity, I am acting as counsel for the
Company in connection with the filing of the above-captioned
Registration Statement on Form S-3 relating to 1,000,000
additional shares of the Company's common stock, without par
value (the "Common Stock"), for issuance pursuant to the terms of
the Company's Dividend Reinvestment and Stock Purchase Plan
("Plan") and of the common stock purchase rights ("Rights") that
are attached to and trade with the shares of the Company's Common
Stock issued pursuant to the terms of such Plan.

     I have examined the Restated Articles of Incorporation of
the Company as amended; the Bylaws of the Company, as amended;
the Registration Statement; the Plan as amended; the resolution
adopted by the Company's Board of Directors on February 13, 1996,
reserving the shares for issuance pursuant to the terms of the
Plan; and such other documents, certificates and corporate or
other records as I have deemed necessary or appropriate as a
basis for the opinion set forth herein.  In my examination, I
have assumed the genuineness of all signatures, the legal
capacity of natural persons, the authenticity of all documents
submitted to me as originals, the conformity to the original
documents of all documents submitted to me as originals or
photostatic copies, and the authenticity of the originals of such
latter documents.  As to any facts material to the opinion
expressed herein which were not independently established or
verified, I have relied upon statements and representations of
officers and other representatives of the Company and others.

     I am admitted to the Bar of the State of Utah, and I express
no opinion as to the laws of any other jurisdiction except the
laws of the United States of America.



     Based upon the foregoing, I am of the opinion that:

     (1)  the Company is a corporation duly organized and
          existing under the laws of the State of Utah;

     (2)  the 1,000,000 additional shares of Common Stock,
          together with the remaining 682,526 shares previously
          reserved and registered, to be issued pursuant to the
          terms of the Plan, when paid for and issued, will be
          validly issued and lawfully outstanding, fully paid and
          non-assessable shares of the Common Stock.

     I hereby consent to the filing of this opinion as Exhibit 5
to the Registration Statement on Form S-3 filed with the
Securities and Exchange Commission by the Company for the
registration of 1,000,000 shares of the Company's Common Stock,
together with the Rights, that may be issued pursuant to the
terms of the Plan.

     I further consent to the reference made to me under the
heading "Legal Opinion" in the Prospectus forming a part of the
Registration Statement.

                                   Sincerely,

                                   /s/ Connie C. Holbrook
