As of today, Hole T and Y are currently being <br />drilled. Additional holes may be necessary. <br />All holes have been drilled on US Forest Service property with the exception of holes Q, V and <br />Z, which were drilled on the Werner property. A drawing is enclosed that shows the location of <br />the drill holes in relation to the underground mine workings. MCC has utilized existing USFS <br />• roads to the extent possible, but has constructed roads off the main USFS road to access the drill <br />sites. The previously mentioned drawing also includes the locations of the roads. Also enclosec <br />is a drawing that shows the approximate location of the disturbance associated with the drilling <br />project. The road loctions and disturbance areas are approximate, as the locations have not yet <br />been surveyed. MCC will provide DIvIG with updated maps once the area and the roads have <br />been surveyed. <br />IvICC has stripped topsoil from the newly constructed roads and drill pad locations. Topsoil <br />stripped from roads has been windrowed to the side of the road. Topsoil stripped from the drill <br />pads has been stockpiled to the uphill side (when possible) of the pads. Drill pads have been <br />bermed to control runoff from the site. <br />MCC expects that some of the drill holes will need to be retained to continue monitoring, but at <br />this time is not sure which holes will be needed. MCC intends to perform interim reclamation <br />following the completion of drilling and sealing (to be discussed in the next section) activities, <br />and final reclamation, which will be completed as the weather conditions improve. <br />The primary goal of the interim reclamation will be to protect topsoil, control drainage, and <br />reduce sedimentation on drill roads and pads. The following tasks will be completed: <br />•Construct berm around topsoil pile <br />. •Ensure berms around drill pads aze intact to contain drainage on pad, or utilize alternate <br />sediment control measures to treat storm water runoff from pad <br />•Grade roads to reduce or eliminate mts <br />•Construct water bazs on roads to control drainage <br />
