Exhibit 99.1

   Pacific Energy Partners, L.P. Reports Record Recurring Earnings
  for Second Quarter 2004; Recurring Earnings Per Unit up 54 Percent

     LONG BEACH, Calif.--(BUSINESS WIRE)--July 28, 2004--Pacific Energy
Partners, L.P. (NYSE:PPX) announced recurring net income for the three
months ended June 30, 2004, of $12.0 million, or $0.40 per diluted
limited partner unit compared to $5.6 million, or $0.26 per diluted
limited partner unit in the second quarter of 2003. Recurring net
income for the second quarter of 2004 excludes a $2.9 million
non-recurring financing expense. Of that 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 recent bond offering and repayment of our term
loan. Including the non-recurring financing expense, net income for
the three months ended June 30, 2004 was $9.1 million, or $0.30 per
diluted limited partner unit.
    The record results of the current quarter reflect the benefit of
the Pacific Terminals storage and distribution system, higher margins
in the gathering and blending operations by Pacific Marketing and
Transportation ("PMT"), and higher volumes and revenue on our Rocky
Mountain pipelines, partially offset by lower volumes and revenue on
our West Coast pipelines.
    On July 19, 2004, the Partnership announced a cash distribution of
$0.4875 per unit for the second quarter of 2004, unchanged from the
prior quarter, but 5.4 percent higher than in the second quarter of
2003. The distribution will be paid on August 13, 2004, to record
holders as of July 30, 2004. Distributable cash flow available to the
limited partners' interest for the second quarter of 2004 was $17.6
million. On a weighted average and diluted basis, there were
29,632,000 limited partner units outstanding during the second quarter
of 2004, approximately 40 percent more units outstanding than in the
second quarter of 2003, due to the equity financings associated with
the Pacific Terminals, Rangeland and Mid Alberta Pipeline ("MAPL")
acquisitions.
    "Our second quarter earnings continue to show the strength of the
Pacific Terminals acquisition. That coupled with the higher gathering
and blending margins achieved by PMT, has more than offset the effect
of lower West Coast pipeline volumes. The West Coast volume decline
was primarily due to high levels of maintenance at Los Angeles Basin
refineries, which extended well into the second quarter," stated Irvin
Toole, Jr., President and CEO. "In addition, our recent acquisition of
the Rangeland Pipeline system contributed to our growth in the Rocky
Mountain region. We expect both Rangeland and MAPL to provide added
value as our integration effort proceeds."
    Mr. Toole continued, "We expect recurring net income per unit for
2004 to be in the range of $1.35 to $1.45 per limited partner unit, an
increase from our prior guidance of $1.30 to $1.40 per unit, and are
forecasting net income for the third quarter of 2004 of $0.28 to $0.32
per unit, reflecting high levels of pipeline maintenance during the
summer months."

    OPERATING RESULTS BY SEGMENT

    WEST COAST OPERATIONS

    Operating income was $14.1 million for the three months ended June
30, 2004 compared to $9.3 million in the corresponding period in 2003.
This increase of 52 percent was primarily due to the income earned by
Pacific Terminals, which we acquired on July 31, 2003, as well as PMT
having unusually high gathering and blending margins. Pipeline volumes
for the three months ended June 30, 2004 were 11 percent lower
compared to the corresponding period in 2003 primarily due to extended
maintenance downtime at the Los Angeles Basin refineries, as well as
reduced California Outer Continental Shelf ("OCS") volumes due to
on-going production decline.
    On May 1, 2004, tariffs were increased by $0.08 per barrel on Line
2000, which averaged 75,000 barrels per day for the quarter. In July
2004, we completed the refurbishment of a 72,000 barrel tank at our
Long Beach Terminal. This is the second tank we have reactivated,
increasing the aggregate storage capacity of Pacific Terminals by
525,000 barrels since December 2003. We expect to make additional
investments to increase our storage capacity as market demand
continues to grow.

    ROCKY MOUNTAIN OPERATIONS

    Operating income was $5.7 million for the three months ended June
30, 2004, compared to $3.3 million in the corresponding period in
2003. The increase of 73 percent was the result of higher pipeline
volumes to the Salt Lake City refineries and to Billings, as well as
the contribution of the Rangeland Pipeline system, which we acquired
on May 11, 2004.
    On June 30, 2004, we completed the acquisition of MAPL. With the
acquisition of Rangeland and MAPL, we are implementing our strategy of
providing a new pipeline corridor from Alberta, Canada to the Rocky
Mountain refineries. The 9,000 barrel per day expansion of pipeline
capacity to Salt Lake City became operational during the second
quarter and is expected to reach full utilization during the third
quarter 2004.

    BOND OFFERING COMPLETED

    In June 2004, we completed an offering of $250 million of 7 1/8%
Senior Notes with a maturity date of June 2014. With the proceeds of
the offering, we repaid our $225 million term loan, thereby extending
the maturity date of our debt from 2009 to 2014. The primary objective
of the bond offering was to increase our financial flexibility for
future growth. Of the $250 million issued, we have converted $80
million from a fixed rate to floating rate. The impact of the offering
to recurring net income and cash flow is essentially neutral.

    CAPITAL EXPENDITURES

    Capital expenditures were $5.5 million for the three months ended
June 30, 2004, of which $4.6 million was related to expansion, $0.7
million was related to the transition of the Rangeland and Pacific
Terminals systems, and $0.2 million was for sustaining capital
projects. We have forecast total capital expenditures of $16.5 million
in 2004, including $10 million for expansion projects, $3 million for
transition capital projects and $3.5 million for sustaining capital
projects.

    We will host a conference call at 2:00 p.m. EDT (11:00 a.m. PDT)
on Thursday, July 29, 2004, to discuss the results of the second
quarter 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 live discussion.

    loan, we had a $2.3 million non-cash write-down of deferred
    financing costs and incurred a $0.6 million cash expense to
    terminate related interest rate swaps.

(3) Distributable Cash Flow provides additional information for
    evaluating our ability to make the minimum quarterly distribution
    and is presented solely as a supplemental measure. You should not
    consider Distributable Cash Flow as an alternative to net income,
    income before taxes, cash flow from operations, or any other
    measure of financial performance presented in accordance with
    accounting principles generally accepted in the United States. Our
    Distributable Cash Flow may not be comparable to similarly titled
    measures of other entities. Additional information regarding
    distributable cash flow is included in our annual report on Form
