As the data from the <br />three sampling episodes indicate, there is considerable difference between the total of site 700 <br />and site 900 and the reading taken at site 29. It is likely that the rating curve at Site 29 is not <br />representative of the actual flow at site 29. <br />Bond Release Findines <br />In accordance with Rule 3.03.2(2), the Division is required to make an evaluation of whether <br />pollution of surface and subsurface waters is occurring, the probability of future occurance of <br />such pollution, and the estimated cost of abating such pollution, prior to releasing any <br />performance bond at a site. <br />Baseline water quantity and quality parameters, and data collected representing existing quality <br />as of January 31, 1994, where available, were compazed to 1998 data for Mine No. 3. <br />Bedrock Water Oualitv <br />Well 008-77-58 is completed in the Wadge overburden downgradient of the reclaimed pit azea. <br />A marked decline in water level in this downgradient well is noted in the data which <br />corresponds to an increase in total dissolved solids in January of 1980, from approximately 300 <br />
