Abstract |
In its evaluation of remaining fossil fuel combustion (FFC) wastes, EPA evaluated damage cases in the same way as in previous reports to Congress for Resource Conservation and Recovery Act (RCRA) SC8002 wastes (i.e., the 1993 Report to Congress on Cement Kiln Dust and the 1990 Report to Congress on Special Wastes from Mineral Processing). Specifically, EPA used a test of proof in these reports to identify documented damage cases. For the current Report to Congress, EPA evaluated a number of cases but found that only some of them met EPA's test of proof. The purpose of this technical background report is to present EPA's analysis of all the cases evaluated and present EPA's reasoning for including or not including the sites in the Report to Congress. |
