It is realized that this <br />material will exhibit diflerent physical properties than the <br />plant reject material tasted is the analysis. However, the <br />rotary breaker reject material comprises only two or three <br />percent of the total amount o! raluse produced. Utilizing <br />the spreading and compacting methods described above, the <br />rotary breaker reject material will be substantially diluted <br />in the placement process and will not aflect the stability of <br />the pile or increase the possibility of combustion. <br />Finally, with respect to stability, the revised design sub- <br />mitted by the previous operator in 1983 contemplated place- <br />ment of refuse material over substantial areas of previously <br />underground mined land. This resulted in the Division's <br />legitimate concern regarding subsidence of old works with <br />respect to refuse embanlffieat stability. Because the refuse <br />area has been reduced in size to that originally proposed in <br />the initial design, there are ao concerns with respect to <br />disposal of refuse material over old underground mine works. <br />Analyais <br />During the initial permit term, the rock underdrain was con- <br />structed accordia6 to the design. Reluse from the pleat was <br />brought out on the reject belt and wan spread and compacted with <br />a D-8 type Terez dozer and an International 560 front-end loader. <br />Due to the fines iron the prep plant belt press, the overall <br />reject had ezeellent strength properties and the moisture content <br />o! refuse leaving the prep plant was near optimum for compaction. <br />Frequent tests o! compaction were made during embanloneat con- <br />struction with good results. Inspection sad certification <br />reports are available in the 1(I.RD files.
