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:

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

         o  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 the combination of these approaches in
      this policy will provide an effective and efficient procedure to
      pre-approve services performed by the independent auditor. 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):

         o  Audit Services

         o  Audit-Related Services

         o  Tax Services

         o  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, 2004 to January 19, 2005, 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:

         o  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

         o  the attestation engagement for the independent auditor's report on
            management's report on internal controls for 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:

              o  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,

              o  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:

              o  employee benefit plan audits,

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

              o  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.

           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 NON-AUDIT 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.


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 levels or 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 this Audit
      Committee on a periodic basis the results of his monitoring.

    procedures.
