ITEM 4.  CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT.

The Board of Directors determined on March 12, 2002 to appoint Ernst & Young LLP
to serve as the Company's independent auditors for the fiscal year ending
December 31, 2002. The appointment of Ernst & Young is being presented to
Valero's stockholders for ratification at the Company's 2002 Annual Meeting of
Stockholders to be held on May 9, 2002. Prior to the selection of Ernst & Young,
Arthur Andersen LLP served as the company's independent auditors.

Arthur Andersen's reports on the Company's consolidated 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 date hereof, there were no
disagreements with Arthur Andersen on any matter of accounting principle or
practice, 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 the
Company's consolidated financial statements for such years; and there were no
reportable events as defined in Item 304(a)(1)(v) of Regulation S-K.

The Company provided Arthur Andersen with a copy of the foregoing disclosures.
Attached as Exhibit 16 is a copy of Arthur Andersen's letter, dated March 13,
2002, stating its agreement with such statements.

During the years ended December 31, 2001 and 2000 and through the date hereof,
the Company 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 the Company's
consolidated financial statements, or any other matters or reportable events as
set forth in Items 304(a)(2)(i) and (ii) of Regulation S-K.
