Exhibit 99.01

                            VALERO ENERGY CORPORATION

                       Audit Committee Pre-Approval Policy

I. STATEMENT OF PRINCIPLES

     Pursuant to Section 10A of the Securities Exchange Act of 1934, as amended
     by Section 202 of the Sarbanes-Oxley Act of 2002 ("SOX Act"), the Audit
     Committee of the board of directors (the "Audit Committee") of Valero
     Energy Corporation (the "Company") is required to pre-approve the audit and
     non-audit services performed by the Company's independent auditor to assure
     that the provision of such services does not impair the auditor's
     independence. The SEC's rules establish two approaches for pre-approving
     services. The two approaches are not mutually exclusive:

        -   the Audit Committee may pre-approve each particular service on a
            case-by-case basis ("separate pre-approval"), and

        -   the Audit Committee may adopt a pre-approval policy that is detailed
            as to the particular types of services that may be provided by the
            independent auditor without consideration by the Audit Committee on
            a case-by-case basis ("policy-based pre-approval").

     The Audit Committee believes that a combination of these approaches will
     provide an effective and efficient procedure to pre-approve services
     performed by the independent auditor. Therefore, unless a type of service
     has received policy-based pre-approval (as specifically identified in the
     appendices to this policy), it will require separate pre-approval by the
     Audit Committee.

     The appendices to this policy contain lists of services that have received
     policy-based pre-approval of this Audit Committee in the following
     categories (categorized in accordance with the SEC's rules):

         -  Audit Services

         -  Audit-Related Services

         -  Tax Services

         -  All Other Services

II. TERM OF PRE-APPROVALS

     The term of the policy-based pre-approvals stated in the appendices to this
     policy is the period from January 1, 2005 to January 31, 2006, unless the
     Audit Committee specifically provides for a different period. The Audit
     Committee will review and pre-approve, at least annually, the services that
     may be provided by the independent auditor. The Audit Committee will revise
     the list of policy-based pre-approved services from time to time as the
     Committee deems necessary or appropriate.

III. DELEGATION

     In accordance with the SOX Act and SEC rules, the Audit Committee hereby
     delegates to its Chairman the authority to grant separate pre-approvals of
     services and fees in accordance with this policy. The Audit Committee may
     further delegate pre-approval authority from time to time to one or more of
     its other members in its discretion. Any committee member to whom
     pre-approval authority is delegated shall report any pre-approval decisions
     to the full Audit Committee at its next meeting. The Audit Committee does
     not delegate its responsibilities to pre-approve services to any member of
     the Company's management.

IV. SERVICES FOR WHICH SEPARATE PRE-APPROVAL IS REQUIRED

     The terms and fees for the following services of the independent auditor
     require separate pre-approval by the Audit Committee:

      -  the annual financial statement audit, including all audits, reviews,
         procedures and other services required to be performed by the
         independent auditor to form an opinion on the Company's consolidated
         financial statements, and

      -  the annual audit of the Company's internal control over financial
         reporting, including all services required to be performed by the
         independent auditor to issue its report on (i) management's assessment
         regarding the effectiveness of the Company's internal control over
         financial reporting, and (ii) the effectiveness of the Company's
         internal control over financial reporting.

     The Audit Committee will monitor these engagements as it deems appropriate,
     and will approve, if necessary, any changes in terms, conditions and fees
     resulting from changes in engagement scope, changes in the Company's
     structure or other matters.

V. SERVICES FOR WHICH POLICY-BASED PRE-APPROVAL IS AVAILABLE

   A. AUDIT SERVICES

     The Audit Committee may grant policy-based pre-approval for Audit Services
     other than the services described in Section IV above. These Audit Services
     are generally services that only the Company's independent auditor
     reasonably can provide, and include:

         -  services associated with SEC registration statements (e.g., comfort
            letters, consents), periodic reports and other documents filed with
            the SEC or other documents issued in connection with securities
            offerings,

         -  statutory audits or financial audits for subsidiaries or affiliates
            of the Company.

      The Audit Committee has given policy-based pre-approval for the Audit
      Services listed in Appendix A. All other Audit Services must be separately
      pre-approved by the Audit Committee.

                                     Page 2


B. AUDIT-RELATED SERVICES

   Audit-Related Services are assurance and related services that are reasonably
   related to the performance of the annual audit or quarterly review of the
   Company's financial statements or that are traditionally performed by the
   independent auditor. The Audit Committee may grant policy-based pre-approval
   for Audit-Related Services. These services would include:

      -  employee benefit plan audits,

      -  due diligence services related to proposed mergers and acquisitions,
         and

      -  assistance with understanding and implementing new accounting and
         financial reporting guidance from rulemaking authorities.

   The Audit Committee believes that the provision of the Audit-Related Services
   listed in Appendix B does not impair the independence of the auditor, and has
   given policy-based pre-approval for the Audit-Related Services listed in
   Appendix B. All other Audit-Related Services must be separately pre-approved
   by the Audit Committee.

C. TAX SERVICES

   The Audit Committee believes that the independent auditor can provide Tax
   Services to the Company such as tax compliance, tax planning and tax advice
   without impairing the auditor's independence. However, the Audit Committee
   will not permit the retention of the independent auditor in connection with a
   transaction initially recommended by the independent auditor, the purpose of
   which may be tax avoidance and the tax treatment of which may not be
   supported in the U.S. Internal Revenue Code and related regulations or in the
   tax laws and regulations of any jurisdiction in which the Company is subject
   to taxation. In addition, the independent auditor may not provide any tax
   services to the Company that are deemed to be incompatible with auditor
   independence per standards promulgated by the Public Company Accounting
   Oversight Board ("PCAOB").

   The Audit Committee has given policy-based pre-approval for the Tax Services
   listed in Appendix C. All other Tax Services must be separately pre-approved
   by the Audit Committee, including Tax Services related to large and complex
   transactions and Tax Services proposed to be provided by the independent
   auditor to any executive officer or director of the Company, in his or her
   individual capacity, when such services are paid for by the Company.

D. ALL OTHER SERVICES

   The Audit Committee may grant policy-based pre-approval for those permissible
   non-audit services classified as All Other Services that it believes are
   routine, recurring services that would not impair the independence of the
   auditor. The Audit Committee has given policy-based pre-approval for the All
   Other Services listed in Appendix D. Any permissible All Other Services that
   are not listed in Appendix D must be separately pre-approved by the Audit
   Committee.

VI. PROHIBITED SERVICES

     A list of the SEC's prohibited non-audit services is attached to this
     policy as Appendix E. The list sets forth the several services that the SOX
     Act and the SEC have specifically identified as services that may not be
     performed by the Company's independent auditor. The Audit Committee will
     consult the SEC's rules and relevant guidance, with the assistance of
     counsel when necessary or appropriate, to determine whether any proposed
     service by the independent auditor falls within any category of prohibited
     non-audit services.

     In addition, the independent auditor may not provide any service or product
     to the Company for a contingent fee (as defined and interpreted by the SEC
     pursuant to Rule 2-01(c)(5) of Regulation S-X) or a commission, or pursuant
     to an agreement (written or otherwise) by the Company to pay a "value
     added" fee based on the results of the independent auditor's performance of
     a service.

VII. PRE-APPROVAL FEE LEVELS AND BUDGETED AMOUNTS

     Pre-approval fee levels or budgeted amounts for all services to be provided
     by the independent auditor will be established at least annually by the
     Audit Committee. All services that have received policy-based pre-approval
     are subject to the pre-approval fee levels or budgeted amounts set forth in
     the appendices to this policy. Any proposed services exceeding these
     amounts will require separate pre-approval by the Audit Committee or by any
     person to whom pre-approval authority is granted under Section III above.

VIII. PROCEDURES

     Requests or applications to provide services that require separate approval
     by the Audit Committee must be submitted to the Audit Committee by both the
     independent auditor and the Company's Chief Financial Officer (or his
     designee), and must include a joint statement as to whether, in their view,
     the request or application is consistent with the SEC's rules on auditor
     independence. In connection with the Audit Committee's consideration of any
     proposed service, the independent auditor, at the Committee's request, will
     provide to the Audit Committee detailed documentation regarding the
     specific services to be provided so that the Committee can make a
     well-reasoned assessment of the impact of the service on the auditor's
     independence.

     The Audit Committee hereby designates the Company's Vice President of
     Internal Audit (the "Monitor") to monitor the performance of all services
     provided by the independent auditor and to determine whether such services
     are in compliance with this policy. The Monitor will report to the Audit
     Committee on a periodic basis the results of his monitoring.

   procedures.
