Item 7.01 Regulation FD Disclosure

     Effective January 1, 2004, Waste Management, Inc. (the “Company”) initiated a landfill pricing study by implementing different levels of price increases at 30 of its landfills. The Company will periodically make reports on the landfill pricing study, which will be included on the Company's website and in reports filed with the Securities and Exchange Commission. This study does not affect the Company’s pricing practices and decisions at its other landfills, which are made from time to time in the ordinary course of its business. The objective of the study is to gather and analyze information to assist the Company in better understanding the reactions to price increases in various markets in the U.S. and Canada.

     The 30 sites were chosen based upon a number of criteria, including broad geographic scope, third party disposal volumes, and internal revenue growth. Although some of the chosen landfills do not meet all of the criteria, the Company attempted to select those landfills for the study that: receive a significant amount of third party disposal volumes; are located within Market Areas where the majority of the volume does not go to municipal sites; and had positive volume internal revenue growth while experiencing flat-to-negative yield internal revenue growth in the first nine-months of 2004.

     The Company will raise disposal pricing on municipal solid waste (“MSW”) and/or construction and demolition waste (“C&D”) at the chosen landfills. The volumes received at the 30 chosen landfills represent approximately 16% of the Company’s total MSW volumes and 7% of its total C&D volumes for the nine months ended September 30, 2004. The Company currently plans for the study to be in effect throughout 2005. Price increases for customers that are not under contract will generally range from 2.5% to 7.5% and will go into effect immediately; however, some customers will be temporarily exempted from the price increase, either because of a recent price increase or certain other factors. Pricing for customers under contract will be limited by the terms of the customers’ agreements.

     The 30 landfills included in the study are:
