5 (FORM 2 -Public filing) <br /> G. Total project area to be disturbed 1.00 (acres) <br /> K. Describe the equipment to be used for the prospecting operations: <br /> Initial evaluation-diesel electric generator;electric mine fan;ventilation fan bag,hand tools as required;diesel or electric <br /> powered rock drill;chipping hammer;air tugger if necessary for ground control work. Tractor mounted backhoe or self propelled <br /> excavator,front end loader,and durrrp truck will be utilized-to clean the existing sedimentation pond and bury and cover the <br /> contents of the sedimentation basin;A small dozer may also be used for site clean-up and maintenance of Storm water <br /> management facilities. a truck will be used for hauling materials. Possible grouting program-grouting equipment as necessary. <br /> Underground locomotive,overshot loader and appropriate mine cars as necessary to complete underground safety work and/or <br /> grouting program. <br /> L. Describe and locate any structures to be constructed(i.e.stockpiles,ponds,impoundments): <br /> No new ponds or impoundments are planned at this time. Existing buildings will be <br /> repaired for this project; a small building may be constructed to house a secondary filter <br /> plant to collect carry-over fine sediment from the sedimentation pond. <br /> M. Describe anticipated relationship to surface water and groundwater(proximity to streams,penetration of ground <br /> water aquifers): <br /> Project is intended to investigate potential reduction of existing groundwater inflows in to the Silver Wing mine. Existing <br /> portal discharge is located-approximately 100 feet above and 300 feet I for izor itally from the Ar in nab Rives.TI le existing <br /> portal discharge varies from 15 to 20 gpm and is routed around the mine dump prior to entering the river. Recent water <br /> quality data is enclosed from ten(10)sets of samples taken between June 29,2011 and September 28,2013. Each <br /> sample set consists of samples taken from the Animas River.both upstream(SW-1)and downstream(SW-3)of the existing <br /> mine features;and,from the portal discharge(SW-2). <br /> IV. OPERATION AND RECLAMATION MEASURES: <br /> 1. The Board suggests that a photographic record of the pre-prospecting and post-prospecting conditions be kept by the <br /> prospector. These photos should be taken from the same location and by the same method to clearly show the pre-prospecting <br /> condition of the land and the reclamation efforts. Upon completion of reclamation and request for bond or surety release,the <br /> Board may consider the photos as evidence of adequate reclamation,and thus, be able to act more quickly on the request for <br /> release. <br /> 2. Provide a description of the native vegetation of the area to be disturbed,including tree,shrub,and grass communities of the <br /> area. Color photographs, sufficient to adequately represent the ecology of the site and adequately labeled (including date, <br /> orientation and location),may be used in lieu of a written description. Based on the quality of the photographs,the Division <br /> may require additional detail. <br /> Ref #1: See attached photographs and descriptions of the pre-prospecting conditions. <br /> No disturbance of existing vegetation is planned. Planned location for burial of settling <br /> pond sludge is in an abandoned site roadway next to settling pond. <br />
