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


I, William L. Trubeck, Executive Vice President and Chief Administrative Officer
of Waste Management, Inc., state and attest that:

         (1) To the best of my knowledge, based upon a review of the covered
reports of Waste Management, Inc., (the "Company") described below, 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 Company's
audit committee.

         (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      the Company's Annual Report on Form 10-K for the year ended
                     December 31, 2001;

              o      all reports on Form 10-Q, all reports on Form 8-K and all
                     definitive proxy materials of the Company filed with the
                     Commission subsequent to the filing of the Form 10-K
                     identified above; and

              o      any amendments to any of the foregoing.
