PART II—OTHER INFORMATION

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

        On March 22, 2002, upon the recommendation of the audit committee, the board of directors approved the dismissal of Arthur Andersen LLP (Arthur Andersen) as Valero L.P.'s independent public accountants and the selection of Ernst & Young LLP (Ernst & Young) as Valero L.P.'s new independent public accountants to audit the consolidated financial statements of Valero L.P. for the year ending December 31, 2002. This change will become effective upon the completion by Arthur Andersen of its audits of the financial statements of the Wichita Falls crude oil pipeline and storage facility operation, which audits are expected to be completed by April 16, 2002.

        Arthur Andersen's reports on Valero L.P.'s (formerly Shamrock Logistics, L.P.) consolidated and combined financial statements for each of the years ended December 31, 2001 and 2000 did not contain an adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles. During the years ended December 31, 2001 and 2000 and through the filing date of this Annual Report on Form 10-K/A, there were no disagreements with Arthur Andersen on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure which, if not resolved to Arthur Andersen's satisfaction, would have caused them to make reference to the subject matter in connection with their report on Valero L.P.'s consolidated and combined financial statements for such years; and there were no reportable events as defined in Item 304(a)(1)(v) of Regulation S-K.

        Valero L.P. provided Arthur Andersen with a copy of the foregoing disclosures. Included as Exhibit 16.1 is a copy of Arthur Andersen's letter, dated April 3, 2002, stating its agreement with such statements.

        During the years ended December 31, 2001 and 2000 and through the filing date of its Annual Report on Form 10-K, Valero L.P. did not consult Ernst & Young with respect to the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on Valero L.P.'s consolidated and combined financial statements, or any other matters or reportable events as set forth in Items 304(a)(2)(i) and (ii) of Regulation S-K.
