J. J. Dudash 2 January 12, 2006 <br />3. In Figure 170 for alluvial well AW-16, there are three field comments that state <br />that the alluvial water was "soapy". Please explain what is meant by "soapy". <br />Also, since this alluvial well is directly down gradient of the gob pile no. 2, <br />please discuss what this field finding may mean for water quality coming from <br />the gob pile. <br />BRL - AW-16 has been basically dry since it was drilled. There has never been <br />adequate water to bail and clean the well. The water present at the bottom of <br />the well has been characterized by the sampler as muddy and soapy at <br />different times. The soap is likely residue from drilling with foam. <br />4. The data presented in Figures 81 and 88 for surface water monitoring stations <br />B-Gulch-lo and C-Gulch-lo respectively have relatively high values for <br />_ __. _ _ _ _ ~_ _conductivity_a~d_certain~onstituents__such as_iron,.sodium,_sulfate_and_calcium. _ _ _- _ <br />Is the Division correct in assuming that these samples were obtained from <br />washdown water from the mine facilities before flowing into sediment ponds B <br />and C, rather than from a precipitation event? <br />BRL -Yes. The samples are obtained at the inlet to the sediment ponds. <br />2004 Bi-Annual Subsidence Report <br />On Map 276, "Subsidence Features" of the Annual Report, there are cross- <br />hatched black and white areas with a "no cracks" notation followed by a date. <br />Is the Division correct in assuming that this refers to areas that showed <br />subsidence cracks in 2004 but which eventually healed by the listed date? <br />Also, the Division requests that a note be added to Map 276 for future Annual <br />Reports that clarifies the meaning of this designation. <br />BRL - The cross-hatched black and white area indicates the locations <br />inspected on the date noted. The "no cracks" notation indicates there were no <br />new subsidence cracks identified during the inspection. <br />If you have any questions, please contact me. <br />Sincerely, <br />~~~~1 <br />J. E. Stover, P.E. <br />Consulting Engineer <br />Enclosures <br />cc: U. S. Forest Service <br />Bureau of Land Management <br />
