This document provides findings of an analysis of cost and economic impacts associated with alternative disposal and management practices for mitigating human health risks from fossil fuel combustion (FFC) wastes. The document is divided into sections covering the following four FFC sectors: Comanaged wastes at coal-fired utilities; Non-utility coal combustion wastes (CCWs); Fluidized bed combustion (FBC) wastes; and Oil combustion wastes (OCWs). It concludes with a section summarizing overall conclusions and presenting industry-level economic impacts. The remainder of this introduction details the approach and methodology used, outlines assumptions, and describes limitations to the analysis.
