The Department of Energy/Morgantown Energy Technology Center (DOE/METC) has initiated research on the disposal of solid wastes from advanced coal processes. The objective of this research is to develop information to be used by private industry and government agencies for planning waste disposal practices associated with advanced coal processes. To accomplish this objective, DOE has contracted Radian Corporation and the North Dakota Mining and Minerals Resources Research Institute (MMRRI) to monitor a limited number of field disposal tests with select advanced coal process wastes. These field tests will be monitored over a three year period to collect data on the field disposal behavior of these wastes. There has been considerable research on the characteristics and laboratory leaching behavior of coal wastes -- a lesser amount on wastes from advanced coal processes. However, very little information exists on the field disposal behavior of these wastes. Information on field disposal behavior is needed (1) as input to predictive models being developed, (2) as input to the development of rule of thumb design guidelines for the disposal of these wastes, and (3) as evidence of the behavior of these wastes in the natural environment.
