</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I am Senior Counsel &#150; Corporate &#038; Securities of Waste Management, Inc., a Delaware corporation
(the &#147;Company&#148;), and have acted in such capacity in connection with the issuance of 318 shares of
the Company&#146;s common stock, par value $0.01 per share (the &#147;Common Stock&#148;). The 318 shares of
Common Stock are being issued under a registration statement on Form&nbsp;S-3 (No.&nbsp;333-137526) filed
under the Securities Act of 1933, as amended.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I have examined corporate documents of the Company, including its Certificate of Incorporation
and Bylaws, and resolutions adopted by its board of directors and committees thereof. I have also
examined the Registration Statement, together with the exhibits thereto, and such other documents
that I have deemed necessary for the purposes of expressing the opinion contained herein. I have
relied on representations made by and certificates of the officers of the Company and public
officials with respect to certain facts material to my opinion. I have made no independent
investigation regarding such representations and certificates.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Based upon the foregoing, I am of the opinion that the Common Stock is validly issued, fully
paid and nonassessable.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I hereby consent to the filing of this opinion as an exhibit to the Registration Statement.
