         Subject: EPA's Expenditures to Clean Up the Bunker Hill Superfund Site

         This letter responds to your request that we review the Environmental Protection
         Agency's (EPA) expenditures for the Bunker Hill Superfund site, a mining area in the
         Coeur d'Alene River Basin in northern Idaho. In 1980, the Comprehensive
         Environmental Response, Compensation, and Liability Act created the Superfund
         program to clean up highly contaminated hazardous waste sites. In 1983, EPA listed
         Bunker Hill on the National Priorities List-the agency's list of the nation's most
         contaminated sites-because contamination from heavy metals and other materials
         posed a severe risk to human health and the environment. EPA's Bunker Hill cleanup
         activities have focused on a 21-square-mile area (referred to as the box) located in
         the center of the 1,500-square-mile river basin.

         Originally, some of the mining companies responsible for the contamination agreed
         to conduct the cleanup work. However, EPA and the state of Idaho took over the
         majority of the cleanup effort following the bankruptcy of a major responsible party.
         In April 1995, EPA and the state of Idaho signed an agreement setting out a cleanup
         strategy with an estimated total cost of $126 million; the agreement also capped the
         state's share of these expenses at $12.6 million.' To implement this agreement, EPA
         segmented the cleanup work into various components-such as the demolition of
         industrial complex structures, removal of contaminated soil in gulches and creeks,
         revegetation of hillsides, and treatment of wastewater-and hired contractors to do
         the work. You asked us to determine (1) EPA's actual expenditures for the cleanup
         activities at Bunker Hill and how these expenditures differ from the estimate set forth
         in the agreement and (2) the reasons for any major differences (defined as $2 million
         or more) between the actual and estimated Bunker Hill cleanup expenditures for
         each component.










         'Any change to this share would require an amendment to the agreement.
