<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Waste Management, Inc., a Delaware corporation (the &#147;Company&#148;) registered,
among other things, the issuance of up to 31,400,000 shares of its common
stock, par value $0.01 per share (the &#147;Common Stock&#148;), on this Registration
Statement on Form S-8 No.&nbsp;333-45066 (the &#147;Registration Statement&#148;) pursuant to
the Waste Management, Inc. 2000 Stock Incentive Plan and the Waste Management,
Inc. 1996 Stock Option Plan for Non-Employee Directors.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On May&nbsp;14, 2004, the Company&#146;s stockholders approved the adoption by our
Board of Directors of the Waste Management, Inc. 2004 Stock Incentive Plan,
under which an aggregate of 34,000,000 shares of our common stock may be issued
pursuant to awards granted under that plan. The terms of the 2004 Stock
Incentive Plan provide that once the plan becomes effective, all shares
available because they are not subject to outstanding awards under our 2000
Stock Incentive Plan and our 1996 Stock Option Plan for Non-Employee Directors
will become available for issuance under the 2004 Stock Incentive Plan.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On May&nbsp;27, 2004, the Company filed a registration statement on Form&nbsp;S-8
No.&nbsp;333-115932 (the &#147;New Registration Statement&#148;), under which, upon its
effectiveness, there will be an aggregate of 34,000,000 shares registered for
issuance, including 548,656 shares and 1,235,000 shares that are not subject to
outstanding awards under the 2000 Stock Incentive Plan and the 1996 Stock
Option Plan for Non-Employee Directors, respectively, and therefore, have been
rolled into the 2004 Stock Incentive Plan.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Pursuant to the principles set forth in Interpretations 89 and 90 under
Section&nbsp;G, &#147;Securities Act Forms,&#148; of the Manual of Publicly Available
Telephone Interpretations of the Division of Corporation Finance of the
Securities and Exchange Commission (July&nbsp;1997) and Instruction E to Form S-8,
we are hereby removing from registration the remaining 548,656 shares under the
2000 Stock Incentive Plan and 1,235,000 shares under the 1996 Non-Employee
Directors&#146; Plan, previously registered under this Registration Statement,
which, as explained, are now registered under the New Registration Statement
for issuance under the 2004 Stock Incentive Plan.
