Pacific Energy Partners, L.P. Announces Second Quarter 2003 Financial
Results

    LONG BEACH, Calif.--(BUSINESS WIRE)--July 30, 2003--Pacific Energy
Partners, L.P. (NYSE:PPX) announced net income for the three months
ended June 30, 2003, of $5.6 million ($0.26 per limited partner unit)
compared to $9.6 million in the corresponding period in 2002. The
Partnership completed its initial public offering in July 2002;
therefore there is no comparable per unit calculation for second
quarter 2002. Net income for the three months ended June 30, 2003,
reflects lower revenues, primarily due to lower West Coast pipeline
volumes and gathering and blending margins, increased general and
administrative expense as a result of our significant growth in 2002
and becoming a public company, and increased interest expense related
to the fixed-rate debt in our post-IPO capital structure compared to
floating-rate debt in the prior year quarter. These factors were
partially offset by lower operating and transition costs.
    For the six months ended June 30, 2003, net income was $11.8
million ($0.55 per limited partner unit) compared with $18.8 million
in the corresponding period in 2002. This decrease was primarily
attributable to lower West Coast pipeline volumes, increased
depreciation related to our March 1, 2002, acquisition of Rocky
Mountain assets, increased general and administrative expense as
described above and increased interest expense associated with our
post-IPO capital structure. These decreases were partially offset by
increased revenue, primarily due to a full six months of operations
for the Western Corridor system and Salt Lake City Core system assets
acquired on March 1, 2002, and lower West Coast operating expenses and
Rocky Mountain transition costs.
    The Partnership announced a quarterly cash distribution on July
18, 2003, of $0.4625 per unit for the second quarter of 2003. The
distribution will be paid on August 14, 2003, to record holders as of
July 31, 2003. Distributable cash flow for the second quarter of 2003
was $10.3 million, or $0.49 per limited partner unit.
    As previously announced, on July 10, 2003, the California Public
Utilities Commission approved the acquisition of the black oil storage
and pipeline distribution assets of Edison Pipeline and Terminal
Company ("EPTC") by Pacific Terminals LLC, a wholly owned subsidiary
of Pacific Energy Partners, L.P. "We are pleased to be adding these
strategic assets to our West Coast operations and are working to close
this acquisition quickly," said Irvin Toole, Jr., President and CEO.
"We expect this acquisition to be accretive to both net income and
distributable cash flow per unit. After we close this acquisition, we
will provide further guidance on 2003 net income and cash
distributions."
    Mr. Toole added, "During the second quarter of 2003, the
Partnership began a feasibility study for developing a deep-water bulk
liquid petroleum import facility at the Port of Los Angeles. We
recently signed a non-binding memorandum of intent with a base-load
customer for the import facility and have submitted an Application for
Development Projects with the Port. During the second half of the year
we will confirm the economic feasibility of the project and pursue a
program of public and regulatory involvement."

    OPERATING RESULTS BY SEGMENT

    WEST COAST OPERATIONS

    Operating income for our West Coast operations was $9.3 million
for the three months ended June 30, 2003, compared to $10.5 million
for the corresponding period in 2002. Second quarter 2003 pipeline
volumes of 156,500 barrels per day were down 10% from 173,500 barrels
per day in the second quarter of 2002. Offshore California ("OCS")
volumes transported to Los Angeles were lower than in the prior year
period primarily due to maintenance downtime at an on-shore processing
facility as well as the normal production decline. In addition,
refinery maintenance in Los Angeles and increased light crude runs at
Bakersfield refineries reduced volumes shipped via our pipelines to
Los Angeles. We also experienced lower margins on our gathering and
blending operations in the 2003 quarter. Total operating costs for
West Coast operations were $11.1 million for second quarter 2003, 10%
less than the $12.4 million recorded in the 2002 quarter.
    For the six month period ended June 30, 2003, West Coast operating
income was $20.0 million compared to $19.9 million for the
corresponding period in 2002. Volumes of 157,900 barrels per day for
the first six months of 2003 were 8% less than in the corresponding
period in 2002. Refinery maintenance in Los Angeles and increased
mid-barrel crude oil ("MBCO") demand in San Francisco reduced MBCO
deliveries to Los Angeles. OCS volumes were lower due to the reasons
described above. Lower operating costs essentially offset the reduced
revenue.

    ROCKY MOUNTAIN OPERATIONS

    Operating income for the three months ended June 30, 2003, for
Rocky Mountain operations was $3.3 million compared to $2.7 million in
the corresponding period in 2002. Salt Lake City refineries
experienced significant down time and reduced demand in the 2003
period, resulting in lower pipeline volumes. For second quarter 2003,
total expenses were $7.4 million compared to $8.2 million in the
second quarter of 2002, primarily as a result of the elimination of
transition costs incurred following the March 1, 2002 acquisition. For
the six months ended June 30, 2003, operating income was $6.6 million
compared to $5.1 million in the corresponding period in 2002. The 2002
period includes only four months of results for the Western Corridor
and Salt Lake City Core systems acquired March 1, 2002.

    CAPITAL EXPENDITURES

    Capital expenditures for the Partnership were $1.2 million for the
six months ended June 30, 2003, of which $0.7 million was for
sustaining, or maintenance projects. We expect maintenance capital
expenditures during 2003 to total approximately $2.5 million. Capital
expenditure guidance for Pacific Terminals will also be provided
following the closing of the EPTC acquisition.

    Pacific Energy Partners, L.P., a Delaware limited partnership
headquartered in Long Beach, California, owns and operates crude oil
midstream assets located in California and the Rocky Mountain region
with over 3,000 miles of pipelines and 4.6 million barrels of storage
capacity. The Partnership is engaged in gathering, blending,
transporting, storing, marketing and distributing crude oil. The
Partnership generates revenues primarily by charging tariff rates for
transporting crude oil through its pipelines.
    We will host a conference call at 4:30 p.m. EDT on Thursday, July
31, 2003, to discuss the results of the second quarter of 2003. Please
