      Pacific Energy Partners, L.P. Reports Record Earnings for
                          First Quarter 2004

    LONG BEACH, Calif.--(BUSINESS WIRE)--April 28, 2004--Pacific
Energy Partners, L.P. (NYSE:PPX) announced net income for the three
months ended March 31, 2004, of $8.1 million, or $0.31 per diluted
limited partner unit compared to $6.1 million, or $0.29 per limited
partner unit in the first quarter of 2003.
    The first quarter 2004 results are the highest quarterly earnings
for the Partnership since its July 2002 initial public offering. The
results of the current quarter reflect the benefit of the Pacific
Terminals storage and distribution system, which was acquired on July
31, 2003, and higher volumes and revenue on the Rocky Mountain
pipelines, partially offset by lower volumes and revenue from the West
Coast pipelines, lower margins in the gathering and blending
operation, and increased maintenance expenses.
    On April 19, 2004, the Partnership announced a cash distribution
of $0.4875 per unit for the first quarter of 2004, unchanged from the
prior quarter but 5.4 percent higher than in the first quarter of
2003. The distribution will be paid on May 14, 2004, to record holders
as of April 30, 2004. Distributable cash flow available to the limited
partners' interest for the first quarter of 2004 was $13.5 million. On
a weighted average and diluted basis, there were 25,149,000 limited
partner units outstanding during the first quarter of 2004,
approximately 20 percent more units outstanding than in the first
quarter of 2003, due to the August 2003 equity financing associated
with the Pacific Terminals acquisition.
    Irvin Toole, Jr., President and CEO, said, "We are pleased to
report record first quarter earnings. The Pacific Terminals storage
and distribution assets that were acquired last July have demonstrated
their value this quarter, with income contribution more than
offsetting the impact of lower West Coast pipeline volumes resulting
primarily from unusually high levels of refinery maintenance in the
Los Angeles Basin. We continue to expect net income per unit for 2004
to be in the range of $1.30 to $1.40 per limited partner unit and are
forecasting net income for the second quarter of 2004 to be in the
range of $0.26 to $0.30 per unit."
    Mr. Toole continued, "Regulatory approvals for the previously
announced Rangeland Pipeline acquisition have been received, and
closing is expected to occur in May 2004. We also expect to sign a
binding purchase and sale agreement for the Mid Alberta Pipeline
assets during the same time period."

    OPERATING RESULTS BY SEGMENT

    WEST COAST OPERATIONS

    Operating income was $12.3 million for the three months ended
March 31, 2004 compared to $10.7 million in the corresponding period
in 2003. This increase of 15 percent was primarily due to the income
earned by Pacific Terminals, which acquired the EPTC storage and
distribution assets on July 31, 2003, partially offset by lower
revenue due to reduced pipeline volumes. Pipeline volumes for the
three months ended March 31, 2004 were 16 percent lower compared to
the corresponding period in 2003 primarily due to extensive
maintenance downtime at Los Angeles Basin refineries. Gathering and
blending margins were also lower than in the prior year quarter, in
part due to reduced demand for blended crude oil caused by new
California gasoline specifications.

    ROCKY MOUNTAIN OPERATIONS

    Operating income was $3.6 million for the three months ended March
31, 2004, compared to $3.3 million in the corresponding period in
2003. This increase of 9 percent was the result of higher pipeline
volumes and revenue partially offset by moderately higher expenses for
maintenance and power. The $3 million expansion of pipeline capacity
to Salt Lake City remains on track to become operational during the
second quarter of 2004.

    CAPITAL EXPENDITURES

    Capital expenditures were $2.4 million for the quarter ended March
31, 2004, of which $0.5 million was for sustaining capital projects.

blends and sells crude oil, activities that are complementary to its
