ITEM  7.    FINANCIAL STATEMENTS, PRO FORMA FINANCIAL INFORMATION AND EXHIBITS.

         (c) Exhibits.

         99.1     Pacific Energy Partners, L.P. Press Release dated January 27,
                  2004.

ITEM  9. AND 12.      REGULATION FD DISCLOSURE; RESULTS OF OPERATIONS AND
                      FINANCIAL CONDITION.

         Attached as Exhibit 99.1 is a copy of a press release, dated January
27, 2004, announcing Pacific Energy Partners, L.P. fourth quarter 2003 financial
results.

         In accordance with General Instruction B.2. of Form 8-K and Securities
and Exchange Commission Release No. 33-8176, the above information is being
furnished under Items 9 and 12 of Form 8-K and is not deemed "filed" for
purposes of Section 18 of the Securities Exchange Act of 1934, is not subject to
the liabilities of that section and is not deemed incorporated by reference in
any filing under the Securities Act of 1933.

         A calculation of distributable cash flow for each of the three and
twelve months ended December 31, 2003 is presented in the press release included
as an exhibit to this Form 8-K. Distributable cash flow is a non-generally
accepted accounting principle financial measure. The amounts included in the
calculation of this financial measure are computed in accordance with generally
accepted accounting principles ("GAAP"), with the exception of maintenance
capital expenditures. Maintenance or sustaining capital expenditures are defined
as only those capital expenditures that do not increase the capacity of an asset
or generate additional revenues or cash flow from operations. The press release
includes a reconciliation of distributable cash flow to net income, which is the
nearest comparable GAAP financial measure.

         We believe that investors benefit from having access to the same
financial measures being utilized by management. Distributable cash flow is a
significant metric used by our management to compare cash flows generated by the
partnership to the cash distributions we make to our partners. Using this
metric, management can quickly compute the coverage ratio of these cash flows to
cash distributions. This is an important financial measure for our limited
partners (including public unitholders) since it is an indicator of our success
in providing a cash return on their investment. Specifically, this financial
measure tells investors whether or not the partnership is generating cash flows
at a level that can sustain or support an increase in our quarterly cash
distributions paid to partners. Lastly, distributable cash flow is the
quantitative standard used throughout the investment community with respect to
publicly-traded partnerships.

         Several adjustments to net income are required to calculate
distributable cash flow. These adjustments include: (1) the addition of non-cash
depreciation and amortization expense; (2) the addition of non-cash amortization
of debt issue costs, which are included in interest expense; (3) the addition of
non-cash employee compensation under the long-term incentive plan, which is
included in general and administrative expense; and (4) the subtraction of
maintenance capital expenditures.
