Changes in engineering estimates typically include minor modiÑcations to the available disposal capacity
of a landÑll based on a reÑnement of the capacity calculations resulting from updated information. Changes in
design typically include signiÑcant modiÑcations to a landÑll's footprint or vertical slopes.
During 2002, total available airspace increased by 22.6 million cubic yards primarily due to the opening of
a greenÑeld site in South Carolina, changes in engineering estimates and changes in design partially oÅset by
consumption. During 2003, total available airspace increased by 56.1 million cubic yards due to new
expansions undertaken, two landÑlls that were acquired during the year and changes in design partially oÅset
by airspace consumption and changes in engineering estimates. During 2004, total available airspace
decreased by 15.5 million cubic yards primarily due to airspace consumption partially oÅset by the acquisition
of a landÑll.
As of December 31, 2004, we owned or operated 58 solid waste landÑlls with total available disposal
capacity estimated to be 1.7 billion in-place cubic yards. Total available disposal capacity represents the sum
