Water that may be "captured" is water that may be routed (by a small berm we'll install to keep unfiltered <br />storm water that falls on the disturbed areas from leaving the site) to lower elevation "discharge" areas. <br />At these areas, we'll construct filters that may be made of rock (similar to a rock "blanket "), straw /hay <br />bales, waddles (a netting tube filled with an inert material (straw, wood chips etc.)), silt fence etc. that will <br />filter silt from the storm water prior to it exiting the site. <br />2. Toward the southern and southwestern boundaries, the topsoil depth becomes less since there is a sand <br />stone shelf in these vicinities. When the reclamation process starts, we may screen this top soil to remove <br />the bigger rocks although this isn't written in the pit's exhibits. If we do screen it, we'll lose that volume of <br />"top soil" that the rocks currently occupy. Please revise the top soil salvage depth range to 4" to 10 ". <br />6.4.5 Exhibit E — Reclamation Plan <br />3. Please revise Exhibit E.2.f.v to reflect topsoil depth as ranging from 4" to 10 ". <br />Sincerely, <br />r /lvr,/ 40 it-t,i vJ� <br />Phil Dorenkamp <br />LAC R &B <br />REcElV <br />Ep <br />MAY n 9 ?� 13 <br />DIV/610NaF <br />M!NlNCANO,3AF ,z� ON <br />
