EaNlslr c <br />NINIBG PLAN <br />1. Dates of mining: Summer of 1988 to fall of 1993. <br />2. Depth of topsoil salvage: 12" to as deep as soil goes. <br />Topsoil to be applied on low areas of adjoining pastures. See <br />Eahiblt C. <br />3. Thickness of overburden: No overburden ae gravel is right <br />under topsoil. See Exhibit E. <br />4. Thickness of deposit to be mined: !0' to 20 ' until bedrock <br />is reached within that distance. <br />5. Major components of the mining operation: 175' road across <br />meadow from ranch road to pit. Movable crusher. See Exhibit <br />E. <br />6. Dimension of gravel pit: 4.2 - S acres. <br />7. Dimensions of exisiting and proposed road: 12'x175' road from <br />ranch road to pit. 1' of gravel dirt mix to be laid across <br />meadow and then removed after gravel operation ie completed, <br />unless we decide to keep the road to service the fish pond. <br />Ranch road to be regravaled wherever needed. <br />g. d••r -.r a F.. •1 rnA nnn -.-i+__ •• ; i'~O W0.5 hr^/! <br />,r-- o r <br />-awe. ever rrvtpfem¢n{-ec <br />9. Ground water sediment-containment: Groundwater is encountered <br />at 3'-4' in early summer and is 6' by mid-summer. I propose <br />to dig a 200' long holding pond on the south end of the pit <br />with 75' of gravel between the pond and stream. The water <br />will be pumped out of the southern end of the pit into the <br />holding pond every morning after the aedlment has had all <br />night to settle. The water dill then drain through 75' of <br />gravel into Che stream. I have found overnight settling to be <br />more than enough time for the water [o clear. <br />L0.

On site processing: Gravel will be crushed and/or screened <br />using a portable crusher to 4 min. r^ ~-;-+'~ '-- •-°°~-' no saa tt <br />wafer fr rh r Pam- rr#-~l--be ^ -'---`--~~ -1^o,^,-r^w^.^ pr-oduch~a!~ <br />a-1-1-en d-a- -o-n. rado or was~r.~~ <br />g' e- Pe'r- Y-pe-r-o per-a'~i <br />ems. <br />
