</TABLE>

Revenues were higher in the nine months and twelve months
ended September 30, 2000 when compared with the same
periods of 1999 due to gas-processing operations added
mid-year 1999 and increased transportation demand.  A
$1.3 million reduction in and subsequent refund of
processing fees in September 2000 caused third quarter
2000 revenues to fall below third quarter 1999 levels.
Processing fees are determined on the basis of cost of
service.  The refund was the result of lower depreciation
costs.  Even considering the refund, gas-processing
revenues for the first nine months of 2000 were $2.7
million higher than was reported for the same period of
1999.  The gas-processing operations remove carbon
dioxide from certain gas supplies to make them suitable
for Questar Gas' system.  Transportation revenues
increased 3% in the third quarter and the first nine
months of 2000 as a result of the addition of several
short-term firm-transportation contracts. Storage
revenues were 1% lower in the third quarter and the first
nine months of 2000.

Operating and maintenance (O & M) expenses were higher in
the 2000 periods when compared with the 1999 periods due
to the combined effect of one-time adjustments recorded
last year that were not repeated in 2000, the inclusion
of gas-processing operations beginning in mid-1999 and
$.5 million of additional legal expenses.  The one-time
adjustments, mostly to capitalize costs incurred in
constructing plant assets, reduced O & M expenses by $1.8
million in the second quarter of 1999.   Gas processing
costs were responsible for roughly $2 million of the
increase in O & M expenses in the first nine months of
2000.

On June 15, 2000, a lawsuit was filed against Questar
Pipeline Company and several of its affiliates by the
partner in the TransColorado Pipeline.  The Company filed
a counterclaim July 27, 2000.   The Company has been
incurring expenses in the defense of its position in the
case.

Depreciation expense was reduced by $1.3 million in the
third quarter of 2000 reflecting a change from 10 years
to 20 years in the estimated useful life of the gas
processing plant.  Depreciation on the plant is
calculated on the straight line method.

Interest and other income in the first nine months of
1999 was increased by the reversal of a $2.5 million
contingency reserve that was not repeated in 2000. The
transaction was related to the completion of the
TransColorado Pipeline and another construction project.

Earnings from unconsolidated affiliates in 1999 included
the Company's share of losses reported by TransColorado
of $2.6 million for the third quarter and $3.2 million
for the first nine months that were not repeated in the
same periods of 2000.  In the fourth quarter of 1999, the
Company wrote down its subsidiary's investment in the
TransColorado Pipeline.

Debt expense was higher in the nine-and twelve-month
periods of 2000 when compared with the 1999 periods
because of additional long-term borrowings.  The Company
borrowed $42 million in October 1999 through a
medium-term note program.  The amount of capitalized
interest costs associated with construction projects has
increased by $.4 million in the first nine months of 2000
when compared with the prior year period.

The effective income tax rate was 37.2% in the first nine
months of 2000 compared with 36.5% in the 1999 period.

Liquidity and Capital Resources

Operating Activities

Net cash provided from operating activities of
$57,125,000 in the first nine months of 2000 was
$58,396,000 more than the amount reported for the same
period of 1999 due primarily to higher income and changes
in operating assets and liabilities. The changes were
associated primarily from lower payments to vendors when
compared with a year ago due to the completion of
construction projects.

Investing Activities

Capital expenditures were $30,845,000 in the first nine
months of 2000 compared with $27,457,000 in the
corresponding 1999 period.  The increase in the 2000
period is primarily due to expenditures for the Southern
Trails pipeline and the purchase of an additional 18%
interest in the Overthrust Pipeline partnership effective
January 1, 2000. Capital expenditures for calendar year
2000 are estimated to be $57.9 million.  Capital
expenditures include capitalized financing charges
(AFUDC) of approximately $4.2 million in 2000 and $3.2
million in 1999.

Financing Activities

Cash flow from operations plus an equity investment from
the Company's parent company were sufficient to fund
capital expenditures, repay a portion of debt owed to
Questar Corporation and pay common dividends.  Questar
Corporation makes loans to the Company under a short-term
credit arrangement.  Borrowings from Questar as of
September 30, amounted to $9.5 million in 2000 and $72.3
million in 1999.   Remaining 2000 capital expenditures
are expected to be financed with net cash provided from
operating activities, borrowings from Questar Corporation
and a possible equity investment from the Company's
parent company.

Early Retirement Offered

On August 28, 2000, Questar's Regulated Services unit
announced an early retirement window program to be
effective October 31, 2000.  A total of 281 employees and
14 disability recipients from Questar Gas, Questar
Pipeline and Questar Regulated Services were eligible for
the enhanced benefit.  The offer was accepted by 262 of
Regulated Services' employees and all 14 long-term
disability recipients.  The window program is projected
to result in pretax labor cost savings for Regulated
Services of over $1 million in 2000 and $6-8 million
yearly.

Regulatory Matters

The Federal Energy Regulatory Commission (FERC) issued a
final order granting a certificate of convenience and
necessity to Questar's Southern Trails Pipeline. The
FERC's July 28 ruling came after the agency became
satisfied that the pipeline was in the public convenience
and necessity and could be completed in an
environmentally sound manner. Southern Trails must
receive final environmental approvals from state and
federal agencies before conversion to carry natural gas
can begin. Under the terms of the certificate, the
Company has two years in which to convert the line to
carry natural gas.  Questar Pipeline is actively working
on right-of-way issues and exploring marketing
opportunities to subscribe Southern Trails' pipeline
capacity.

Revenue Recognition Guideline Issued by the Securities
and Exchange Commission (SEC)

In December 1999, the SEC issued Staff Accounting
Bulletin (SAB) 101, "Revenue Recognition in Financial
Statements." The SAB raised issues concerning the timing
of recording revenues given that sales transactions may
contain some conditions allowing customers to return
products or receive refunds.  The SEC expects companies
that make conditional sales to postpone fully recognizing
revenues until the earnings process is completed.  The
Company records revenues when services are provided or
products are delivered.  Periodically revenues are
collected subject to refunds pending final orders from
regulatory agencies.  In those situations, revenues are
reported net of estimated refunds.  The pronouncement is
effective for Questar Pipeline beginning with the fourth
quarter of 2000 and is not expected to cause a change in
the method used to record revenues.

                               Part II
                          Other Information

Item 1.   Legal Proceedings.

     On October 31, 2000, KN TransColorado, Inc. ("KNTC"), a
subsidiary of Kinder-Morgan, Inc. ("Kinder-Morgan") filed a motion
to dissolve the TransColorado Gas Transmission Company ("TC
Partnership") and appoint a receiver to operate the TransColorado
pipeline project.  KNTC and Questar TransColorado, Inc. ("QTC"),
which is a wholly owned subsidiary of Questar Pipeline Company
("Questar Pipeline" or the "Company"), are 50 percent owners in the
TC Partnership. The motion was filed as part of the complex
litigation that is pending in a Colorado state district court in
which the Company and Questar Corporation are named defendants in
addition to QTC.  The litigation involves claims and counterclaims
concerning QTC's contractual right to put its 50 percent ownership
interest in the TC Partnership to KNTC during the 12-month period
commencing March 31, 2001.  See the Company's Form 10-Q for the
quarter ended June 30, 2000, Item 1.  Legal Proceedings, for
additional information concerning the case.

     QTC has submitted KNTC 's motion to dissolve the TC Partnership
and appoint a receiver to the administrative agent for the TC
Partnership's $200,000,000 credit facility to determine if it has
any impact on the terms of such facility.  After the original
complaint was filed in June of 2000, QTC and KNTC, on behalf of the
TC Partnership, and Questar Pipeline and Kinder-Morgan, as
guarantors, executed an amendment to the credit agreement that the
complaint itself did not constitute an event of default.  Questar
Pipeline has provided a guaranty of $100,000,000 for the credit
facility.

     QTC and its affiliates have filed a motion to dismiss KNTC's
complaint or, in the alternative, to stay the action and refer some
issues raised in the complaint to the Federal Energy Regulatory
Commission for resolution.  They also filed a counterclaim and third
party complaint against KNTC and specified affiliates, including
Kinder-Morgan.

Item 5.   Other Information.

     Messrs. Gary W. DeBernardi, Lowell F. Gill, and Stephen C.
Yeager resigned as officers of the Company effective October 31,
