</TABLE>

Revenues were higher in the 3- and 12-month periods of 1998 due
primarily to increased firm-transportation reservation charges.
Questar Pipeline is expanding working gas capacity at Clay Basin
in 1998 by 5 Bcf at an estimated cost of $4 million.  In an open
season sign-up conducted in January 1998, all potential new
capacity was pledged under long-term commitments. The expansion
is expected to add about $3 million in annual storage revenues
beginning in the second quarter of 1998.

Operating and maintenance (O & M) expenses were 11% higher in
the first quarter 1998 when compared to the same period of 1997
due primarily to a timing difference in billings from a
technology supplier.  O & M expenses were lower in the 12 months
ended March 31, 1998 due primarily to cost efficiencies
resulting from sharing services with an affiliated company.
Questar Gas Company and Questar Pipeline share the costs of
certain administrative, marketing, accounting, technical and
related services under Questar Regulated Services Co.

Depreciation expense was higher in the 1998 periods as a result
of increased investment in property, plant and equipment.  Other
taxes were lower in the first quarter of 1998 and in the
12-months ended March 31, 1997 as a result of receiving property
tax refunds in the first quarter of 1998 and the third quarter
of 1996.

Income from unconsolidated affiliates in the 1998 periods
includes the Company's share of earnings reported by
TransColorado Gas Transmission Co.  The earnings reflect
capitalization of interest and equity costs (AFUDC) associated
with the construction of the TransColorado pipeline amounting to
$318,000 in the 3 months ended March 31, 1998 and $4,774,000 in
the 12 months ended March 31, 1998.

The effective income tax rate was 32.4% in the first quarter of
1998 compared with 37.1% in the first quarter of 1997 due to
adjustments that reduced 1998 tax expenses.

A regulatory proceeding involving Questar Pipeline, Federal
Energy Regulatory Commission (FERC) Docket No. IN97-1, has been
resolved by an order issued March 2, 1998.  The FERC found that
Questar Pipeline was not liable for any refunds related to
charges made to Questar Gas for rendering gathering services.


Liquidity and Capital Resources

Operating Activities

Net cash provided from operating activities of $7,545,000 in the
first quarter of 1998 was 17% below the $9,086,000 reported for
the same period in 1997 due primarily to changes in operating
assets and liabilities.

Investing Activities

Capital expenditures were $5,084,000 in the first quarter of
1998 compared with $3,270,000 in the corresponding 1997 period.
Capital expenditures for calendar year 1998 are estimated to be
$76,100,000, which includes $27,700,000 for the Company's share
of equity investments in unconsolidated affiliates.

Financing Activities

The Company has a short-term line-of-credit arrangement with a
bank totaling $200,000.  No amounts were borrowed under this
arrangement at March 31, 1998.  In addition, Questar Corporation
loans funds to the Company under a short-term arrangement.  As
of March 31, amounts borrowed from Questar were $19,100,000 in
1998 and $4,000,000 in 1997.   First quarter financing
activities focused on payment of dividends and a partial
repayment of the Company's notes payable to Questar.  Capital
expenditures for 1998 are expected to be financed from net cash
flow provided from operations and short- and long-term debt
including borrowings from Questar.


Forward Looking Statements

This 10-Q contains forward-looking statements about the future
operations and expectations of Questar Pipeline.  According to
management, these statements are made in good faith and are
reasonable representations of the Company's expected performance
at the time.  Actual results may vary from management's stated
expectations and projections due to a variety of factors.
