Explanatory Note:

This Amendment No. 1 to the Annual Report on Form 10-K for the fiscal year ended December 31, 2005 (the "Annual Report") of
Pacific Energy Partners, L.P. is being filed solely to amend Item 10: Directors and Executive Officers of the Registrant, previously filed with the Annual Report, to provide disclosure under the
heading "Section 16(a) Beneficial Ownership Reporting Compliance" of the failure by one director and one officer to timely file Form 5s, in order to comply with the requirements
of Item 405 of Regulation S-K. Form 5s were required to report the holdings of these individuals as of December 31, 2005 because of purchases during 2005 from
reinvestments of distributions in the individuals' brokerage accounts, amounting to purchases of an aggregate of approximately 600 common units, which were not reported during 2005 on Form 4s
because they were small acquisitions exempt under Rule 16a-6.

In
addition, this filing amends Item 15: Exhibits and Financial Statement Schedules, previously filed with the Annual Report, to provide new certifications by each principal executive
officer and principal financial officer, as required by Rule 12b-15 of the Securities Exchange Act each time an amendment to the Annual Report is filed.

Except
as described above, this Form 10-K/A does not update or otherwise amend the Annual Report as previously filed for changes in events, estimates or other
developments subsequent to March 13, 2006 (the date of the original filing of the Annual Report).

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires directors, officers and persons who beneficially own more than 10% of a class of our equity securities
that is registered under Section 12 of the Exchange Act to file with the SEC and the New York Stock Exchange initial reports of ownership and reports of changes in ownership of such securities.
These persons are also required to furnish us copies of all of the Section 16(a) reports they filed. Based solely upon a review of the copies of reports on Forms 3, 4 and 5 furnished to
us, or written representations that no reports on Form 5 were required, we believe the directors and officers of our General Partner, our General Partner in its capacity as a beneficial owner
and any other persons who beneficially own more than 10% of our common units complied with all filing requirements with respect to transactions in our equity securities in 2005, except that
Mr. Polson inadvertently omitted from reports filed by him on Form 4 during 2005 four sales transactions pursuant to a 10b5-1 plan, involving 100, 200, 500 and 500 of our
common units, which

5

---



were
omitted as a result of administrative error by Mr. Polson's brokerage firm, and Mr. Lemmon and Mr. Boarts each failed to timely file a Form 5. Mr. Polson
and Mr. Lemmon were required to file Form 5s to report their holdings as of December 31, 2005 because of purchases during 2005 from reinvestments of distributions in the their
brokerage accounts, amounting to purchases of an aggregate of approximately 600 common units, which were not reported during 2005 on Form 4s because they were small acquisitions exempt under
Rule 16a-6.

Director Independence

The New York Stock Exchange ("NYSE") listing standards requiring a majority of directors to be independent do not apply to publicly traded limited partnerships
like the Partnership. Four directors are "independent" as that term is defined in the applicable NYSE rules and Rule 10A-3 of the Exchange Act. In determining the independence of
each director, the Board has adopted certain categorical standards. PEM's independent directors as determined in accordance with those standards are: David L. Lemmon, Jim E. Shamas, John C. Linehan
and William L. Thacker. The categorical standard adopted by the Board are as follows:

---





For
purposes of the above-described categorical standards, the term "immediate family member" includes a person's spouse, parents, children, siblings, mothers- and
fathers-in-law, sons- and daughters-in-law, brothers- and sisters-in-law and anyone (other than domestic employees)
who shares such person's home; provided, that any such persons who no longer have any such relationship as a result of legal separation or divorce, or death or incapacitation, shall not be considered
immediate family members.

Committees and Meetings

The Board of Directors has the responsibility for establishing broad policies and for our overall direction and management. The Board of Directors held four
regular meetings and six special meetings during 2005. The Board has established standing committees to consider designated matters. The standing committees of the Board are Audit, Compensation,
Conflicts, and Nominating and Governance.

Audit Committee

The members of the Audit Committee are: David L. Lemmon, Chairman, Jim E. Shamas, John C. Linehan and William L. Thacker. The members of the Audit Committee are
not officers or employees of our General Partner. Among other things, the Audit Committee is responsible for reviewing our external financial reporting, including reports filed with the SEC, engaging
and reviewing our
independent auditors, and reviewing procedures for internal auditing and the adequacy of our internal accounting controls. The Committee held six meetings during 2005.

The
Board of Directors has determined that all of the members of the Audit Committee are "audit committee financial experts," as that term is defined under the Securities Act and the
Exchange Act, and that each is "independent," as that term is used in the Exchange Act.

Compensation Committee

The members of the Compensation Committee are: Jim E. Shamas, Chairman, David L. Lemmon, John C. Linehan, Christopher R. Manning and William L. Thacker. The

recommending
guidelines for corporate governance, and leading the Board in its annual review of the Board's performance. The Committee held four meetings in 2005.

Executive Sessions

The Board of Directors holds executive sessions for the non-management directors on a regular basis without management present. Since the
non-management directors include directors who are not independent directors, the independent directors also meet in separate executive session without the other directors or management at
least once each year to discuss such matters as the independent directors consider appropriate. A majority of the independent directors select a presiding director for these executive sessions. In
addition, any director may call for an executive session of non-management or independent directors at any Board of Directors meeting.

Communications from Unitholders, Employees and Others

Unitholders, employees and other interested persons who wish to communicate with the Board of Directors, non-management directors as a group, a
committee of the Board of Directors or a specific director may do so by letters so addressed to the care of PEM's corporate secretary. Letters addressed to the Board of Directors in general will be
reviewed by PEM's corporate secretary and relayed to the Chairman of the Board of Directors or the chair of an appropriate committee. Letters addressed to the non-management directors in
general will be relayed unopened to the chair of the Audit Committee. Letters addressed to a committee of the Board of Directors or a specific director will be relayed unopened to the chair of the
committee or the specific director to whom they are addressed. All letters regarding accounting, accounting policies, internal accounting controls and procedures, auditing matters, financial reporting
processes, or disclosure controls and procedures are to be forwarded by the recipient director to the chair of the Audit Committee.

Code of Ethics

Our General Partner has adopted a code of ethics that applies to all employees, including its principal executive officers, principal financial officer, principal
accounting officer and its Board of Directors. A copy of the code of ethics is available on our Internet website at www.PacificEnergy.com, and is available in print to any holder of our units who
requests it from our Investor Relations Department. Our General Partner intends to satisfy the disclosure requirement under Item 10 of the current report on Form 8-K regarding an
amendment to, or a waiver from, a provision of its code of ethics by posting such information on our website at the Internet website address set forth above.

Corporate Governance Matters

The NYSE requires the chief executive officer of each listed company to certify annually that he is not aware of any violation by the company of the NYSE
corporate governance listing standards as of the date of the certification, qualifying the certification to the extent necessary. The Chief Executive Officer of the General Partner provided such
certification to the NYSE in 2005 without qualification. In addition, the certifications of the General Partner's Chief Executive Officer and Chief Financial Officer required by Section 302 of
the Sarbanes-Oxley Act have been included as exhibits to the Partnership's Annual Report on Form 10-K.

Reimbursement of Expenses of the General Partner

Our General Partner does not receive any management fee or other compensation for its management of the Partnership. However, our General Partner and its
affiliates are reimbursed for all expenses incurred by them on our behalf. These expenses include the costs of employee, officer and director compensation and benefits properly allocable to us and all
other expenses necessary or appropriate to the conduct of our business. The partnership agreement provides that our General Partner may determine the expenses that are allocable to us in any
reasonable manner determined by our General Partner in its sole discretion.
