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 Energy & Environmental Research Center (EERC) to design, construct, and monitor a limited number of field disposal tests with advanced coal process wastes. These field tests will be monitored over a three year period with the emphasis on collecting data on the field disposal 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 (a) as input to predictive models being developed, (b) as input to the development of rule of thumb design guidelines for the disposal of these wastes, and (c) as evidence of the behavior of these wastes in the natural environment.

Radian Corporation and the North Dakota Energy and Environmental Research Center (EERC) are funded to develop information to be used by private industry and government agencies for managing solid wastes produced by advanced coal combustion processes. This information will be developed by conducting several field studies on disposed wastes from these processes. Data will be collected to characterize these wastes and their interactions with the environments in which they are disposed. Three sites were selected for the field studies: Colorado Ute`s fluidized bed combustion (FBC) unit in Nucla, Colorado; Ohio Edison`s limestone injection multistage burner (LIMB) retrofit in Lorain, Ohio; and Freeman United`s mine site in central Illinois with wastes supplied by the nearby Midwest Grain FBC unit. During the past year, field monitoring and sampling of the four landfill test cases constructed in 1989 and 1991 has continued. Option 1 of the contract was approved last year to add financing for the fifth test case at the Freeman United site. The construction of the Test Case 5 cells is scheduled to begin in November, 1992. Work during this past year has focused on obtaining data on the physical and chemical properties of the landfilled wastes, and on developing a …

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 Energy & Mineral Research Center (EMRC) to design, construct and monitor a limited number of field disposal tests with advanced coal process wastes. These field tests will be monitored over a three year period with the emphasis on collecting data on the field disposal of these wastes. The specific objectives for the reporting period were as follows: review fourth site candidates; obtain site access for the Freeman United site; select an ash supplier for the Illinois site and initiate subcontracts for on-site work; commence construction of the Freeman United test cell; and obtain waste for the Colorado Ute test site. Accomplishments under each task are discussed.

This quarterly report details activities during this reporting period.

The specific objectives for the reporting period of October, 1992 to December, 1992 were as follows: (1) Finish analyzing leachates from the third annual core samples from the Ohio site, collected in August 1992; (2) Collect and analyze the sixth quarterly water samples from the first Illinois test case in August, 1992. Make field measurements and collect data from the data logger; (3) Begin construction of the second Illinois test case; (4) Continue production of a video presentation on the project; (5) Load all remaining EERC data on the Colorado and Ohio sites into the project database; (6) Finalize plans with METC for continued monitoring at the Colorado and Ohio sites beyond the initial three year period, and (7) Submit and the Final Case Report on the Colorado site to the DOE and EPRI.
