    Pacific Energy Partners, L.P. Announces Approval by California
      Public Utilities Commission of EPTC Facilities Acquisition


    LONG BEACH, Calif.--(BUSINESS WIRE)--July 10, 2003--Pacific Energy
Partners, L.P. (NYSE:PPX) announced that the California Public
Utilities Commission, at its July 10, 2003, meeting, approved the
pending sale by Southern California Edison Company ("SCE") of its
Edison Pipeline and Terminal Company ("EPTC") assets to Pacific
Terminals LLC, an affiliate of the Partnership.
    "We are pleased to receive regulatory approval and begin the
process of closing this strategic acquisition, which will expand our
services in the Los Angles area through the addition of significant
storage and terminaling assets with waterborne import and export
capability," said Irvin Toole, Jr., President and CEO of the
Partnership's general partner. Mr. Toole also stated, "We have been
working closely with SCE, its employees, and customers to facilitate a
smooth transition when we begin operating these assets."
    The Partnership anticipates that all remaining contractual
conditions and requirements will be satisfied in time to allow for a
closing within approximately 30 days.
    The EPTC facilities consist of approximately 9.4 million barrels
of storage capacity, of which approximately 6.7 million barrels are in
active commercial service, and 119 miles of distribution pipelines.
The facilities specialize in the storage and distribution of crude oil
and other dark products and serve major refineries, pipelines, and
marine terminals in the Los Angeles basin.
    The purchase price of these assets is $158.2 million, plus upward
adjustments for certain pre-closing capital expenditures and
prepayments made by SCE and the value of displacement oil and
warehouse inventory. The Partnership expects that these adjustments
will total approximately $5 million to $10 million. The Partnership
intends to finance this acquisition with proceeds from its $200
million revolving credit facility. Subsequent to the closing, the
Partnership anticipates repaying a portion of this borrowing with
proceeds from the issuance of additional common units.
    Pacific Energy Partners, L.P., a Delaware limited partnership
headquartered in Long Beach, California, owns and operates crude oil
midstream assets 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.
