Environmental assessment: source test and evaluation report - coal preparation plant no. 2. Final report Sep 79-Mar 81

Technical Report ·
OSTI ID:5494776
; ; ;
The report gives results and conclusions of a source test and evaluation program at a coal preparation plant, representing cleaning plants that process run-of-mine coal with high pyritic sulfur content, use high technology coal cleaning processes, operate in a high-rainfall environment, and have a low soil-neutralization potential. The major objective of the program was to perform an environmental assessment on the plant's waste streams and fugitive emissions. Chemical analysis results indicated that all streams, except fugitive particulates, contained constituents which may have a potentially harmful health and/or ecological effect. For streams showing potential for ecological effects, Mn was of concern; for streams showing a potentially harmful health effect, Mn and Cr were of prime concern. Contrary to previous studies, high NH3 concentrations were observed in the leachate. Further investigation of the NH3 source is warranted. Bioassays for fugitive particulates, sedimentation pond waters, and fine refuse slurry solid samples indicated moderate biological effects. For leachates, all health-related bioassays showed a low or nondetectable effect; however, the coal and coarse refuse leachate composite and the pond sediment composite produced a moderate effect on the ecological related algae test.
