EXHIBIT 99.1

                   STATEMENT UNDER OATH OF PRINCIPAL EXECUTIVE
                    OFFICER REGARDING FACTS AND CIRCUMSTANCES
                        RELATING TO EXCHANGE ACT FILINGS

I, Raymond W. LeBoeuf, state and attest that:

         (1)      To the best of my knowledge, based upon a review of the
                  covered reports of PPG Industries, Inc., and, except as
                  corrected or supplemented in a subsequent covered report:

                  o        no covered report contained an untrue statement of a
                           material fact as of the end of the period covered by
                           such report (or in the case of a report on Form 8-K
                           or definitive proxy materials, as of the date on
                           which it was filed); and

                  o        no covered report omitted to state a material fact
                           necessary to make the statements in the covered
                           report, in light of the circumstances under which
                           they were made, not misleading as of the end of the
                           period covered by such report (or in the case of a
                           report on Form 8-K or definitive proxy materials, as
                           of the date on which it was filed).

         (2)      I have reviewed the contents of this statement with the Audit
                  Committee of the Board of Directors of PPG Industries, Inc.

         (3)      In this statement under oath, each of the following, if filed
                  on or before the date of this statement, is a "covered
                  report":

                  o        Annual Report on Form 10-K for the fiscal year ended
                           December 31, 2001 of PPG Industries, Inc.;

                  o        all reports on Form 10-Q, all reports on Form 8-K and
                           all definitive proxy materials of PPG Industries,
                           Inc. filed with the U. S. Securities and Exchange
                           Commission subsequent to the filing of the Form 10-K
                           identified above; and

                  o        any amendments to any of the foregoing.
