Additional research has brought to light <br />evidence that many of the hydrologic concerns are not valid. <br />First, the main item of concern is sulfur in the " oor material <br />due to a sample which shows a pyritic sulfur content of 3.26. <br />~ini~ was an error^ecusly labeled sample. The Tateria? wa; act:.a':;y <br />the bottom coal of the "A" seam. This occurred because the <br />operator had designated to ACZ (the firm doing the sampling), <br />that the bottom 6 inches of the coa'. seam in one area of the <br />outcrop was cco high in sulfur and would not be mined, therefore. <br />it was assumed at the time to be floor mater~a'. <br />Other evicence has been found which strongly indicate gnat the <br />sulfur in the bottom of the "A" seam is very localized and wil', <br />not present a problem for all of the mining in the proposed <br />permit area. This evidence is discussed below: <br />i) the log for drill hole AM-18, closest to the h'.gh sulfur area, <br />has a wiggle at the bottom of the density log which indicates the <br />high pyritic content of this material. A:i other logs for the <br />permit area and Werth ir. Section 16 do not show any evidence of <br />this pyrite. <br />"c) The Victory #3 Mine, located immediately sout~nwest of the <br />portal area, drains to low point on Coai Gulch where a discharge <br />p=oe was placed in the portal. Discharge frcm this mine, in the <br />"~" seam, has never shown any acid water at all. -he Victory #' <br />
