Exhibit 99.1

Pacific Energy Partners, L.P. Reports Earnings for Fourth Quarter and
               Full Year 2004 and Provides 2005 Guidance

    LONG BEACH, Calif.--(BUSINESS WIRE)--Feb. 2, 2005--Pacific Energy
Partners, L.P. (NYSE:PPX) announced fourth quarter and full year 2004
recurring net income in line with previously published guidance.
Recurring net income for the three months ended December 31, 2004, was
$9.4 million, or $0.31 per diluted limited partner unit, compared to
recurring net income of $8.0 million, or $0.31 per diluted limited
partner unit, in the fourth quarter of 2003. Recurring net income for
the full year ended December 31, 2004, was $39.4 million, or $1.36 per
diluted limited partner unit, compared to recurring net income of
$26.7 million, or $1.16 per diluted limited partner unit, for full
year 2003.
    On January 21, 2005, the Partnership announced an increase in its
cash distribution to $0.50 per unit for the fourth quarter of 2004, or
$2.00 per unit annualized. This represents an increase of 2.6% over
its previous quarterly distribution level of $0.4875 per unit, or
$1.95 per unit annualized. The distribution will be paid on February
14, 2005, to record holders as of January 31, 2005.
    "We had a very good year in 2004," stated Irv Toole, President and
CEO. "Both of our strategic asset groups continue to strengthen and
grow, as shown by our distribution increase this quarter. The Pacific
Terminals storage and distribution system is a strong and growing
asset in our West Coast segment. Our Rocky Mountain segment has
enjoyed the benefits of a concerted marketing effort in the US, as
well as the early impact of the Canadian pipelines we acquired in
2004. By entering this new market, we have gained access to growing
synthetic crude oil production, as well as a customer base that will
have a positive impact on our future volumes in the Rocky Mountains.
In addition, increasing volumes on the Western Corridor and Salt Lake
City Core systems further enhance our revenue growth. We're excited
about the growth potential in both of our operating segments."

    FOURTH QUARTER RESULTS

    Recurring net income for the three months ended December 31, 2004,
was $9.4 million, or $0.31 per diluted limited partner unit, compared
to recurring net income of $8.0 million, or $0.31 per diluted limited
partner unit, in the fourth quarter of 2003. Recurring net income for
the 2004 quarter excludes a non-cash impairment expense of $0.8
million associated with the pending sale of an idle Pacific Terminals
property. Recurring net income for the 2003 quarter excludes a $1.6
million rate case and litigation settlement expense. Including the
non-recurring expenses, net income for the three months ended December
31, 2004, was $8.6 million, or $0.29 per diluted limited partner unit,
compared to $6.4 million, or $0.25 per diluted limited partner unit,
for the fourth quarter of 2003.
    The fourth quarter of 2004 reflects an increase in Pacific
Terminals' storage and distribution revenues due to greater storage
capacity and higher utilization. Pacific Pipelines experienced higher
revenues due to improved volumes and tariff increases. The quarter
also reflects the benefit of increased volumes and revenue on our
Rocky Mountain pipelines. Offsetting these benefits were substantially
lower gathering and blending margins of Pacific Marketing and
Transportation ("PMT").
    Included in fourth quarter 2004 results are two acquisitions: the
Rangeland Pipeline system, which was acquired on May 11, 2004; and the
Mid Alberta Pipeline ("MAPL"), which was acquired on June 30, 2004.
    Distributable cash flow available to the limited partners'
interest for the fourth quarter of 2004 was $15.1 million. On a
weighted average and diluted basis, there were 29,665,000 limited
partner units outstanding during the fourth quarter of 2004,
approximately 18% more units outstanding than in the fourth quarter of
2003.

    FULL YEAR RESULTS

    Recurring net income for the year ended December 31, 2004, was
$39.4 million, or $1.36 per diluted limited partner unit, compared to
recurring net income of $26.7 million, or $1.16 per diluted limited
partner unit, for full year 2003. Recurring net income for the 2004
period excludes a non-cash impairment expense of $0.8 million and a
$2.9 million financing expense. Of the $2.9 million financing expense,
$2.3 million was a non-cash write-down of previously deferred
financing costs, and $0.6 million was a cash payment to terminate
interest swap agreements, both associated with our $250 million bond
offering in June 2004 and repayment of our term loan. Recurring net
income for the 2003 period excludes a $1.6 million rate case and
litigation settlement expense. Including the non-recurring expenses,
net income for the year ended December 31, 2004, was $35.7 million, or
$1.23 per diluted limited partner unit, compared to $25.0 million, or
$1.09 per diluted limited partner unit, for the year ended December
31, 2003.
    For the year ended December 31, 2004, the improvement in recurring
net income was due primarily to increased Rocky Mountain volumes, the
benefit of the Canadian acquisitions, and a full year benefit of
Pacific Terminals, which was acquired on July 31, 2003. These benefits
were partly offset by lower gathering and blending margins and lower
West Coast pipeline volumes.
    For full year 2004, distributable cash flow available to the
limited partners was $61.6 million. On a weighted average and diluted
basis, there were 28,488,000 limited partner units outstanding for
full year 2004, approximately 26% more units outstanding than in full
year 2003. Our distribution coverage ratio for full year 2004 was 1.1
times. The distribution coverage ratio is the ratio of distributable
cash flow available to the limited partners compared to distributions
paid to them for the year.

    OPERATING RESULTS BY SEGMENT

    WEST COAST OPERATIONS

    Operating income was $11.0 million for the three months ended
December 31, 2004, after the $0.8 million impairment expense, compared
to $11.9 million in the corresponding period in 2003. Pacific
Terminals had higher utilization as well as increased storage
capacity, resulting in increased revenues. Pipeline volumes for the
three months ended December 31, 2004, were approximately 7% higher
than in the corresponding period of 2003, primarily due to San
Francisco-area refinery maintenance, which resulted in an increase in
volumes moving south to the Los Angeles Basin refineries. PMT
continued to experience lower gathering and blending margins in the
fourth quarter, due to competitive pricing pressures as a result of
steeply discounted foreign crude oil entering the West Coast market.
This pricing pressure began in the third quarter of 2004 and is
expected to continue through the first quarter of 2005. At that time,
an existing PMT contract that has resulted in adverse pricing
consequences will terminate.
    On January 10, 2005, Shell announced an agreement to sell their
Bakersfield refinery to Flying J. The Partnership believes there could
be an opportunity to transport additional volumes of crude oil to the
Bakersfield refinery and additional mid-barrel volumes from the
refinery to Los Angeles.
    In the third quarter of 2004, producers began the development of
the Rocky Point field in the California Outer Continental Shelf
("OCS"), with the drilling of the first of eight planned wells. The
second well is anticipated to be completed soon. Rocky Point is
estimated by the operator to have reserves of up to 50 million barrels
of crude oil, and the Partnership anticipates that a significant
portion of the Rocky Point production will be transported on its
pipelines.
    The Partnership recently installed vapor treating equipment at a
cost of $0.6 million at its Pacific Terminals facilities, which is
expected to reduce third-party contractor costs by approximately $1
million annually. In addition, the Partnership has filed an
application with the California Public Utilities Commission for the
sale of certain surplus properties that were part of the Pacific
Terminals acquisition. The fourth quarter impairment expense of $0.8
million is associated with one of these properties. It is expected
that the overall sales program will result in an improvement to net
income as well as approximately $10 million of cash proceeds.
    For the year ended December 31, 2004, operating income was $48.7
million, after the $0.8 million impairment expense, compared to $42.7
million for the year ended December 31, 2003. This increase was
primarily attributable to a full year benefit of the Pacific Terminals
storage and distribution system, which was acquired on July 31, 2003.
PMT experienced lower gathering and blending margins in the third and
fourth quarter of 2004, as well as reduced demand for PMT's blended
crude. Pipeline volumes for the year ended December 31, 2004, were 6%
lower than in the year ended 2003, primarily due to OCS production
declines, as well as increased crude runs by Bakersfield refineries
which reduced the volumes available to move south to Los Angeles.
Helping to offset lower volumes were increased tariff rates on Line
2000 in May 2004 and Line 63 in November 2004, and a more favorable
tariff mix.
    The future growth strategy in West Coast operations focuses on
expansion, both through development projects and through acquisitions.
At present, Pacific Terminals has approximately 1.5 million barrels of
idle storage, which can be reactivated as demand increases, and
existing gas oil storage can continue to be converted to high demand
crude oil storage, providing less seasonality. In addition, pipeline
tariff rate increases, as well as new services to our customers, are
assessed periodically. We also expect to capitalize on the anticipated
growth of crude oil imports to the Los Angeles Basin, with our Pier
400 deepwater import terminal project. The project continues to move
forward in securing additional customer commitments, as well as
progressing the environmental permitting process.

    ROCKY MOUNTAIN OPERATIONS

    Operating income was $6.8 million for the three months ended
December 31, 2004, compared to $2.4 million in the corresponding
period in 2003. The increase included results of the Rangeland
Pipeline system, which was acquired on May 11, 2004, as well as higher
pipeline volumes on all US Rocky Mountain systems driven by an
increase in demand by the refineries in Salt Lake City and Billings.
On our Salt Lake City Core system, higher gathered and truck volumes
also increased revenues.
    On December 1, 2004, we increased our location differentials for
the Rangeland Pipeline system. Location differentials are the
difference between the values of the purchase and sale contracts for
crude oil and related products transported between various origin and
destination points on Rangeland's pipeline. In addition, the new
receiving terminal and pump station for Rangeland, which will provide
access to synthetic and other types of crude oil in Edmonton, is in
the initial development stages. Construction of this facility is
expected to be completed and begin operations at the beginning of the
fourth quarter of 2005.
    For the year ended December 31, 2004, operating income was $23.7
million, compared to $13.1 million for the year ended December 31,
2003. Strengthened demand at Billings in the latter half of the year,
as well as the increased demand by the Salt Lake City refineries,
helped drive higher pipeline volumes on all US Rocky Mountain systems.
The 9,000-barrel-per-day expansion at Wahsatch, completed in the
second quarter of 2004, further increased volumes into Salt Lake City.
The Partnership is currently evaluating a second expansion phase into
Salt Lake City to meet increasing demand.
    Expansion projects, such as the one into Salt Lake City, are an
integral part of Pacific's strategy for growth in the Rocky Mountain
segment. Our Western Corridor and Salt Lake City Core system, as well
as Frontier Pipeline, all have the potential for expansion to meet the
projected demand in the area. Other enhancement projects such as
additional tankage, truck terminals or gathering connections would
provide increased volume and revenue. Lastly, acquisitions that
further enhance or expand the existing infrastructure of the strategic
pipeline corridor created by the acquisition of the Rangeland Pipeline
system are being evaluated.

    CAPITAL EXPENDITURES

    Capital expenditures were $16.5 million for the year ended
December 31, 2004, of which $12.9 million was related to expansion,
$1.6 million was related to the transition of the Rangeland and
Pacific Terminals systems, and $2.0 million was for sustaining capital
projects.

    LOOKING FORWARD

    For the first quarter ending March 31, 2005, we are forecasting
net income of $0.28 to $0.32 per unit. For full year 2005, we expect
net income to be in the range of $1.38 to $1.46 per unit. We are
forecasting capital expenditures for the full year 2005 of $36.5
million, of which $23 million is related to expansion, $11 million is
related to transition projects and $2.5 million is related to
sustaining capital projects. In addition, upon completion of its
terminal and pump station in Edmonton, Alberta, with the expected
increase in volumes, the Partnership previously announced that it
expects to increase its distribution by 5% for the fourth quarter of
2005, payable in February 2006.
    Mr. Toole stated, "We continue to focus on enhancing our existing
strategic asset groups, as well as expansion into other midstream
pipeline or terminal businesses. We look forward to further increases
in our cash distributions as we develop the Rangeland Pipeline system,
complete additional acquisitions, and pursue key development projects,
such as Pier 400. We are excited about our prospects for 2005 and
beyond."

    OTHER MATTERS

    On October 29, 2004, we announced that The Anschutz Corporation
had agreed to sell its 36.6% interest in the Partnership (the
"Transaction"), to LB Pacific, LP, formed by Lehman Brothers Merchant
Banking Group. Under the terms of the Transaction agreement, The
Anschutz Corporation will sell its 10,465,000 subordinated units,
representing a 34.6% limited partner interest and its 2% general
partner interest. The closing of the Transaction is anticipated to
occur in the first quarter of 2005. In the guidance provided for 2005
as listed above, we have not included any non-recurring costs
associated with the Transaction, including an expense for the
accelerated vesting of restricted units outstanding under the
Partnership's long-term incentive plan, in accordance with the terms
of the restricted unit agreements.
    The Partnership will host a conference call at 2:00 p.m. EST
(11:00 a.m. PST) on Thursday, February 3, 2005, to discuss the results
of the fourth quarter and full year of 2004. Please join us at
www.PacificEnergy.com for the live broadcast. The call, with questions
and answers, will continue to be available on our web site following
the call.
