The mining <br />activities are not visible from the road. <br />Currently, our permit requires 6 to 12 inches of topsoil/overburden replacement. I request that the <br />requirement for topsoil/overburden material be eliminated. We have found the deposit to be quite <br />homogeneous from the ground surface to the total depths of excavation (approx. 20 to 30 ft) thus far. A <br />few acres of past excavations have been re-contoured with material taken from the excavations and are re- <br />vegetating. , <br />Sincerely, <br />~ ~> ~ /~ <br />"~(- ~ ~ Cijcxec9.~~i <br />Rex Goodrich, PE <br />Region 3 Assistant Materials Engineer <br />Cc Candice Lukow <br />John Gunn <br />File <br />~~ •- ~~„ ~. ,. .'~ ~ ~ ~. ..,, :. . _.-.,,__._ ~: ~~: , ~.~ r,<r ,,.. ~-<, ~...,=tip, ,i- <br />
