<br />DISCUSSION OF FIELD SAMPLING PROCEDURES <br />Greg Lewicki, mining engineer for D. H. Emling Company, was the sole <br />person involved in taking samples. <br />To assure representative samples, the following steps were taken: <br />(1) During initial prep plant operation, many adjustments were <br />made to produce clean coal and refuse of the proper quality <br />and quantity. Most of this work was done during December <br />1982. Refuse samples were taken on January 17-20, 1983, after <br />all adjustments were made. <br />(2) Samples were taken from the coal refuse belt immediately after <br />the belt left the prep plant. A shovel was used to grab samples <br />from the belt at 1/2 hour intervals over a period of three days <br />on the daylight shift. No samples were taken from the temporary <br />refuse stockpile. <br />(3) Immediately after collection, all samples were placed in plastic <br />drums and sealed to preserve the moisture content of the refuse <br />as it was produced. <br />(4) A total of 75 pounds of sample refuse was sent to the laboratory <br />for analysis. <br />It should be noted that rotary breaker reject material was not included in <br />the physical analysis because of its larger size. Although it is recognized that <br />this material could have significantly different physical properties, it only <br />comprises 2 to 3% of the total refuse produced, and is not expected to alter the <br />stability of the embankment. This aspect will be discussed in more detail in the <br />request for revision. <br />D. H. EMLING COMPANY <br />
