Alluvial monitoring wells will be install at locations were access is readily available <br />so road construction will not be required. Atruck-mounted. hollow stem au eg r will <br />be used to install 2-inch diameter monitoring wells. The same a ui ment will be <br />used to drive the sampling barrel and 3/4-inch well casing for the smaller diameter <br />wells. Well installation procedures have been outlined in the Alluvial Groundwater <br />Characterization plan prepazed by Adrian Brown Consultants for the Big Elk Mine. <br />Section 4.3 from this document is included with the NO[. <br />b. Specifically address: <br />(1) Location and acreage of azeas where topsoil will be salvaged and stored; <br />No topsoil will be removed or stockpiled <br />(2) How much earth moving will be needed for new roads or drill sites, if any; <br />Drill pads or access roads will not be constructed. <br />(3) What seed mix (type and amount) will be used for revegetation; <br />The vegetation and soils will not be impacted by the well installations. <br />(4) Depth of drill holes; <br />The expected depth of drilling is 20 to 50 feet. <br />(5) Whether aquifers will be encountered (include supporting references); <br />Drilling will start from ground surface and continue until bedrock is <br />encountered. Only alluvial groundwater will be encountered during drilling <br />(6) Precise description of how drill holes will be sealed and plugged in <br />accordance with Rule 4.07; and <br />All boreholes will be converted to alluvial monitoring wells. Details on well <br />completions aze given in Section 4.3 of Adrian Brown Consultants' Work <br />Plan for Alluvial Groundwater Characterization. Big Elk Mine (couv <br />attached . <br />
