Pacific Energy Partners, L.P. Reports Earnings for Second Quarter 2005

    LONG BEACH, Calif.--(BUSINESS WIRE)--Aug. 2, 2005--Pacific Energy
Partners, L.P. (NYSE:PPX) ("Pacific") announced that net income for
the three months ended June 30, 2005, was $12.2 million, or $0.40 per
limited partner unit, compared to net income of $9.1 million, or $0.30
per limited partner unit, for the period ended June 30, 2004.
Recurring net income for the three months ended June 30, 2005, was
also $12.2 million, or $0.40 per limited partner unit, compared to
recurring net income of $12.0 million, or $0.40 per limited partner
unit, in the second quarter of 2004. All per unit amounts in the text
of this news release are reported on a diluted basis. Recurring net
income for the second quarter of 2004 excludes a $2.9 million write
off of deferred financing costs associated with last year's bond
offering and term loan repayment.
    The results for the quarter ended June 30, 2005, reflect increased
pipeline volumes in the Rocky Mountains, higher tank utilization and
additional storage capacity for Pacific Terminals, and the benefit of
a full quarter of operations in 2005 for the Rangeland system, which
was acquired in May 2004. These increases were offset by lower
pipeline volumes on the West Coast and by $1.4 million of pipeline
repair and maintenance costs associated with earth movement and stream
erosion due to heavy rainfall in Southern California.
    For the six months ended June 30, 2005, net income was $15.6
million, or $0.58 per limited partner unit, compared to $17.2 million,
or $0.62 per limited partner unit, for the period ended June 30, 2004.
Recurring net income for the six months ended June 30, 2005, was $22.6
million, or $0.74 per limited partner unit, compared with $20.1
million, or $0.72 per limited partner unit, for the six months ended
June 30, 2004. Net income for the first six months of 2005 reflects
the benefit of a full six months of operations in 2005 for the
Rangeland system, which was acquired in May 2004, higher pipeline
volumes in the Rocky Mountains, and higher storage and terminaling
revenues for Pacific Terminals. Offsetting these increases were
significantly lower gathering and blending margins from PMT compared
to higher than average margins experienced in the same period of 2004,
and $2.0 million of unscheduled repairs and maintenance associated
with earth movement and stream erosion problems caused by the heavy
rainfall in Southern California.
    Recurring net income for the six months ended June 30, 2005,
excludes a $2.0 million expense for the insurance deductible
associated with the remediation of the Pyramid Lake oil release on
Line 63, a $3.1 million expense related to the accelerated vesting of
restricted units under Pacific's long-term incentive plan as a result
of the change in control attributable to the purchase of Pacific's
general partner by LB Pacific, LP, and a $1.8 million expense as a
result of the general partner transaction (an item that was required
to be recorded as a partnership expense with the general partner's
payment of it recorded as a capital contribution). Recurring net
income for the six months ended June 30, 2004, excludes the $2.9
million write off of deferred financing costs.
    "We are pleased with the continued progress of our two strategic
business units, which we expect will be further enhanced by the
acquisition of storage and pipeline assets from Valero L.P. that was
previously announced. Our May 2004 Rangeland acquisition continues to
exceed expectations, and has also been adding value to our U.S. Rocky
Mountain pipelines. We are currently progressing a series of expansion
projects to increase capacity on the Glacier system, Frontier
pipeline, and the Salt Lake City Core system to be completed in phases
over the next several years," stated Irv Toole, President and CEO of
Pacific. "Our second quarter results continue to show the strength of
the Pacific Terminals storage and distribution system on the West
Coast. That, coupled with the pipeline volume growth that our Rocky
Mountain business unit has experienced, has offset the effect of lower
West Coast pipeline volumes and significant pipeline repair costs
associated with record rainfall in Southern California."
    On July 21, 2005, Pacific announced a cash distribution of $0.5125
per unit for the second quarter of 2005, or $2.05 per unit annualized.
This is unchanged from the first quarter 2005 distribution level and
is 5.1% higher than the second quarter 2004 distribution level. The
distribution will be paid on August 12, 2005, to holders of record as
of August 1, 2005.
    Distributable cash flow available to the limited partners'
interest for the second quarter of 2005 was $18.2 million. On a
diluted weighted average basis, there were 29,742,000 limited partner
units outstanding during the second quarter of 2005.
    Pursuant to the terms of the partnership agreement, on August 12,
2005, 2,616,250 subordinated units owned by LB Pacific, LP will
convert on a one-for-one basis to common units. The conversion of the
subordinated units will not affect future cash distributions.

    OPERATING RESULTS BY SEGMENT

    WEST COAST BUSINESS UNIT

    Operating income was $12.4 million for the three months ended June
30, 2005, compared to $14.1 million in the corresponding period in
2004.
    West Coast pipeline volumes for the three months ended June 30,
2005, were approximately 14% lower than in the second quarter of 2004.
During the quarter, volumes were impacted by unplanned Los Angeles
area refinery maintenance, lower Outer Continental Shelf (OCS)
production due to maintenance activities, natural production decline,
and diversion of some volumes north to San Francisco. In addition,
although Pacific was able to shift significant volumes of crude oil
from Line 63 to Line 2000 during the period that Line 63 was out of
service due to the landslide at Pyramid Lake, some volumes were lost
during this quarter as customers sought to ensure their supply.
    In March 2005, Pacific experienced a significant oil release on
Line 63 in northern Los Angeles County in the Pyramid Lake area, which
was caused by a rain-induced landslide. In addition, record rainfall
in Southern California caused stream erosion and earth movement,
exposing Pacific's pipelines in multiple locations. The total costs
associated with the oil recovery and restoration effort at Pyramid
Lake is now estimated at $15 million. Pacific believes that its
insurance carrier will pay these costs, excluding a $2.0 million
deductible, and has been receiving timely reimbursements to date.
Additionally, Pacific estimates that the cost of pipeline repairs and
improvements associated with the Pyramid Lake landslide and the costs
to address earth movement and stream erosion problems at other
locations along Line 63 and Line 2000 will total approximately $5.5
million, of which $3.7 million is expected to be expensed and $1.8
million is expected to be capitalized. Of the expense portion, $1.4
million and $2.0 million were incurred during the second quarter and
year-to-date periods, respectively. The California Public Utilities
Commission recently approved our application to implement a temporary
surcharge of $0.10 per barrel on Line 63 long haul tariff rates,
effective August 1, 2005, to recover the repair costs and insurance
deductible.
    Pacific Terminals' storage facilities had a higher rate of
utilization during the quarter, as well as increased storage capacity.
The higher utilization was primarily the result of refinery
maintenance in the Los Angeles Basin.
    PMT margins were unchanged in the second quarter of 2005 from the
second quarter of 2004. On July 1, 2005, Pacific purchased certain
crude oil contracts and crude oil inventories for $2.2 million plus
additional future payments to be made over the next three-and-one-half
years, based on the performance of the contracts. The purchase
contracts were integrated into PMT's business.
    Pacific continues to advance the Pier 400 deepwater import
terminal project in the environmental permitting process, as well as
in securing additional customer commitments. Pacific expects to have
the permits necessary to begin construction in the second quarter of
2006, with completion and start-up expected in the fourth quarter of
2007.

    ROCKY MOUNTAIN BUSINESS UNIT

    Operating income was $9.0 million for the three months ended June
30, 2005, compared to $5.7 million in the corresponding period in
2004. The increase included a full quarter's results of the Rangeland
system which was acquired in May 2004, as well as increased market
share for pipeline shipments of crude oil to Billings, Montana, and
increased crude oil demand by Salt Lake City refiners. Pipeline
volumes in the U.S. Rocky Mountains for the second quarter of 2005
were approximately 5% higher than in the corresponding quarter of
2004. Salt Lake City Core and Frontier Pipeline volumes improved due
to an increase in capacity resulting from an agreement in June 2005
with the connecting carrier.
    In Canada, the new receiving terminal and pump station for
Rangeland, which will provide access to synthetic and other types of
crude oil in Edmonton, is expected to begin operations in the middle
of the fourth quarter of 2005.

    LOOKING FORWARD

    For the full year ending December 31, 2005, Pacific is forecasting
recurring net income of $1.37 to $1.45 per unit. Included in the full
year guidance is $0.15 per limited partner unit of unusual and
unanticipated expense, including $3.7 million of pipeline repairs on
Line 63 and Line 2000 associated with earth movement and stream
erosion and $0.7 million of similar repairs on Rangeland pipeline,
which was also impacted by record-setting rains late in the second
quarter. For the quarter ending September 30, 2005, Pacific is
forecasting net income of $0.24 to $0.28 per unit. This guidance does
not include the benefit of the acquisition of assets from Valero L.P.
discussed further below. Reconciling items between projected recurring
net income and net income for full year 2005 are unchanged from those
set out in the attached schedule for the six months ended June 30,
2005.
    As previously announced, management intends to recommend a
distribution increase of $0.03 per limited partner unit per quarter,
associated with the acquisition of assets from Valero L.P., and an
additional $0.0125 per quarter increase associated with the start-up
of the initiating synthetic crude oil facility in Edmonton. These
expected increases are unchanged by the unusual costs described above.
    For the full year, Pacific is projecting total capital
expenditures of $57 million, including $42 million for expansion
projects, $12 million for transition capital projects, and $3 million
for sustaining capital projects. The Partnership is increasing its
profit generating capital forecast by $17 million, principally in the
Rocky Mountains and for Pier 400. These estimates exclude any planned
expansion projects associated with the assets being acquired from
Valero L.P.

    ACQUISITION OF CERTAIN ASSETS FROM VALERO L.P.

    On July 5, 2005, Pacific announced that it had signed a definitive
agreement to acquire certain terminal and pipeline assets from
subsidiaries of Valero L.P. consisting of two California terminals
handling refined products, refinery blend stocks, and crude oil with
4.1 million barrels of storage, three East Coast refined and specialty
products terminals with 3.2 million barrels of storage, and a 550-mile
refined products pipeline with four truck terminals and 1.7 million
barrels of storage in the U.S. Rocky Mountains. The aggregate purchase
price is $455 million. Pacific expects to fund the acquisition by
issuing common units for approximately 60-65% of the acquisition price
and debt securities for approximately 35-40% of the acquisition price.
The acquisition of these assets is expected to close by the end of
September 2005.
    Pacific will host a conference call at 2:00 p.m. EDT (11:00 a.m.
PDT) on Wednesday, August 3, 2005, to discuss the results of the
second quarter of 2005. Please join us at www.PacificEnergy.com for
the live broadcast. The call, with questions and answers, will
continue to be available on Pacific's web site following the call.

    About Pacific Energy:

    Pacific Energy Partners, L.P. is a master limited partnership
headquartered in Long Beach. Pacific is engaged principally in the
business of gathering, transporting, storing, and distributing crude
oil and other related products in California and the Rocky Mountain
region, including Alberta, Canada. Pacific generates revenues
primarily by transporting crude oil on its pipelines and by leasing
capacity in its storage facilities. Pacific also buys, blends, and
sells crude oil, activities that are complementary to its pipeline
transportation business. Pacific Energy recently announced the signing
of a definitive agreement to purchase several refined products
terminals and a pipeline for $455 million. Closing is expected by the
end of September 2005 following receipt of regulatory approvals.

    This news release may include "forward-looking" statements within
the meaning of Section 27A of the Securities Act of 1933, as amended,
and Section 21E of the Securities Exchange Act of 1934, as amended.
All statements other than statements of historical fact included or
incorporated herein may constitute forward-looking statements.
Although Pacific believes that the forward-looking statements are
reasonable, it can give no assurance that such expectations will prove
to be correct. The estimates associated with the acquisition are based
on facts known at the time of estimation and Pacific's assessment of
the ultimate outcome. Among the factors that could cause results to
differ materially are regulatory and other closing requirements and
the successful integration and future performance of the assets
acquired. The forward-looking statements involve risks and
uncertainties that may affect Pacific's operations and financial
performance. Among the factors that could cause results to differ
materially are those risks discussed in Pacific's filings with the
Securities and Exchange Commission, including our Annual Report on
Form 10-K for the year ended December 31, 2004.
    The estimates associated with the oil release are based on facts
known at the time of estimation and the Partnership's assessment of
the ultimate outcome. Among the many uncertainties that impact the
estimates are the necessary regulatory approvals for, and potential
modification of remediation and repair plans, the amount of data
available at the time of the assessment of the impact of soil and
water contamination, the current uncertainty of the geological
conditions that will be encountered during the final repairs of the
Line 63 pipeline, changes in costs associated with environmental
remediation services and equipment, and the possibility of third-party
legal claims giving rise to additional expenses. Therefore, no
assurance can be made that costs incurred in excess of the estimated
costs, if any, would not have a material adverse effect on the
Partnership's financial condition, results of operations, or cash
flows, although the Partnership believes it is likely that most, if
not all, of any such excess cost, to the extent attributable to
clean-up and third-party claims, would be recoverable through
insurance. As new information becomes available in future periods, the
Partnership may change its expense accrual and recovery estimates.

(1) General and administrative expenses, accelerated long-term
    incentive plan expense, transaction costs, interest expense, other
    income, and foreign income tax expense are not allocated among the
    West Coast and Rocky Mountain business units.
(2) On March 3, 2005, in connection with the change in control of
    the Partnership's general partner, all restricted units
    outstanding under the Long-Term Incentive Plan became immediately
    vested pursuant to the terms of the grants. The Partnership
    recognized accelerated compensation expense of $3.1 million
    relating to the vesting.
(3) Pursuant to an Ancillary Agreement, our general partner reimbursed
    us $1.8 million for costs incurred in connection with the sale of
    our general partner. Generally accepted accounting principles
    require us to record an expense with the reimbursement shown as a
    partner's capital contribution.

(1) On March 23, 2005, there was an oil release of approximately
    3,400 barrels in northern Los Angeles County. Although this event
    will involve an outlay of cash, we believe these costs are unusual
    and are not indicative of the Partnership's recurring earnings.
(2) The cash cost associated with the accelerated vesting of units
    is $2.0 million. However, we have not deducted this amount in
    determining distributable cash flow as the accelerated vesting was
    unusual and not indicative of the Partnership's recurring
    earnings.
(3) Pursuant to an Ancillary Agreement, our general partner reimbursed
    us $1.8 million for costs incurred in connection with the sale of
    our general partner. Generally accepted accounting principles
    require us to record an expense with the reimbursement shown as a
    partner's capital contribution.
(4) In June 2004, in connection with the repayment of our term 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.
(5) 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
    10-K for the year ended December 31, 2004.
