was reached. When access was granted, samples were collected at the Rienau # 2 site in late September, thereby supplementing the sampling that had already been completed. With the inclusion of the Rienau # 2 data, all reclaimed portions of the Meeker Area Mine site were represented within this 1995 study. In accordance with the DMG Bond Release Guidelines, a minimum of 15 samples was agreed upon to be spread throughout the disturbed areas. Within individual. reclaimed subunits (see Table 1, Appendix Map), random sample locations were drawn from gridded disturbed area maps (100 x 100 ft grid for cover transects, 50 x 50 ft grid for production plots) and were located in the field through the use of a compass and pacing. Cover and production sample location are marked on the enclosed map. As noted above, sample placement over the entire mine site followed a proportional allocation design. The number of samples taken in each reclaimed subunit is listed in Table 1 of the Appendix along with estimates of disturbed acreage. The first column in the table lists the acreage for each individual reclaimed subunit. The next column indicates the percentage of the total mine reclaimed area that is contributed by each subunit. This value is then multiplied by the total expected number of samples to be placed over the entire mine site indicating how many samples were to be placed in each subunit. This value is listed in the third column and, in column four, is rounded to the nearest integer to indicate the actual number of samples to be carried out. The fifth column indicates the weight each subunit is accorded in the overall sample based on the rounded or final sample values. It is useful to note that column five and column two values do not differ in any important way, confirming that for the number of samples involved in the study, rounding to whole numbers did not introduce any important exaggeration or underrepresentation of any of the subunits with respect 4
