                      [WASTE MANAGEMENT, INC. LETTERHEAD]


                              FOR IMMEDIATE RELEASE


     WASTE MANAGEMENT COMMENTS ON ARTHUR ANDERSEN'S SETTLEMENT WITH THE SEC

HOUSTON, JUNE 19, 2001 -- Waste Management, Inc. (NYSE: WMI) responded today to
the announcement that its outside auditor, Arthur Andersen LLP, had reached a
settlement with the Securities Exchange Commission regarding audits done for a
wholly-owned subsidiary of Waste Management, Inc. for the calendar years in the
period from 1993 through 1996 and the 1998 restatement of such subsidiary's
financial statements. The subsidiary, which at that time was known as Waste
Management, Inc. (Old Waste Management), was merged with a wholly-owned
subsidiary of USA Waste Services, Inc. in 1998, and changed its name to Waste
Management Holdings, Inc. USA Waste Services, Inc. then changed its name to
Waste Management, Inc. (New Waste Management).

"Although the Company was never a party to the proceedings that the SEC
instituted against Arthur Andersen, we are pleased that the matter was resolved
to the satisfaction of both the SEC and Arthur Andersen," said A. Maurice Myers,
Chairman, Chief Executive Officer and President of Waste Management. "The former
officers of the Old Waste Management that were referenced in Arthur Andersen's
settlement with the SEC are no longer at Waste Management, and we have worked
hard to put in place a new management team that can both prevent the problems of
the past and focus attention on enhancing our position as the industry's leading
provider of comprehensive waste management services. Arthur Andersen's
resolution of its issues with the SEC is another major step in accomplishing
that goal and in putting the issues surrounding the February 1998 restatement
behind us."

The settlement relates to an investigation by the SEC involving Old Waste
Management's 1998 restatement of its prior financial statements for the calendar
years from 1993 through 1996, which were audited by Arthur Andersen. Waste
Management has cooperated fully with the SEC in the investigation, and does not
believe that the SEC will seek any action against Waste Management in connection
with the events detailed in the Arthur Andersen settlement. "Waste Management
has resolved most of the litigation arising out of the 1998 restatement,
including

the settlement of a shareholder class action suit in Chicago and a recent
agreement to settle a class action pending in federal court in Boston by
individuals who sold their companies to Old Waste Management between 1990 and
1997 in return for Old Waste Management's common stock", said Mr. Myers. "The
Company is continuing to work diligently to bring the remaining suits or
proceedings arising out of the 1998 restatement to a conclusion in the near
future."

         Waste Management, Inc. is its industry's leading provider of
comprehensive waste management services. Based in Houston, the Company serves
municipal, commercial, industrial, and residential customers throughout North
America.
