Response to Adequacy Comments Dated June 5, 2013 <br />July 4, 2013 <br />Page 2 of 2 <br />13) 6.3.3 (m) The French drain will be built above the large process pond and will <br />operate in conjunction with the de- watering area (slimes pond). A 30 foot by 30 foot pit <br />will be dug sloping to a depth of 5 feet. This area should allow most of the sand and a <br />little of the slimes to fall out and settle. The remaining suspended solids will then flow <br />over a 15 foot wide weir to spread the material flow and reduce its velocity. The slimes <br />would then fall into a 15 foot by 15 foot by 8 foot deep pit filled with washed gravel and <br />rock up to 3 inch. The aggregate will serve as filter media to trap as much of the slimes <br />as possible. Cobble will be placed on the far end of the drain to prevent out wash of the <br />filter media. The use of the French drain is intended to keep effluent out of the pond and <br />provide us with the lightest possible processing water. A diagram of the design is <br />included in this packet. <br />14) 6.3.3 (m) This statement should read: 5 foot wide by 30 foot long sluice box <br />15) 6.3.4 (c) No slimes will be blended with salvaged topsoil. The volume of slimes re- <br />blended with the minus 3 inch rock, gravel and sand will be 16.4 percent. This re- <br />blended material will then be mixed with hay and composted. After composting has <br />occurred the organic loam will be compacted, hand raked and seeded at a rate equal to 40 <br />pounds per acre. <br />
