r,r�• STATE 0 COLORADO FW: Kokes Pit Betty <logrb @kci.net> To: peter. hays @state. co. us, mkokes @mcgwd.org From: Environment -Inc [mailto :Environment- inc @outdrs.net] Sent: Thursday, December 12, 2013 12:19 PM To: Logan County Roads Cc: Anne Korbe Subject: Kokes Pit Chad, Mon, Dec 16, 2013 at 8:12 AM Here is the map I called about, I did it in Adobe so you could just look at it instead of going to Leibert's. The brown areas are those that need to be sloped 4:1. I have labeled each with the amount of material needed to accomplish that. These are estimates only but would give you an idea of their size. The green line is the line I would suggest you expand to so there is enough room to work above the mine face. Basically I suggest you move the west and first leg of the south line out 100 feet and bled it with the red line to define you permit areas. You don't have to use this new area but if you do, it is in the permit so you don't have to expand the mine area again. This will have little effect on the permit and if it isn't needed for sloping then it does not need to be reclaimed. I think there is enough material in the permit area to do the work you want, it is just a function of how you want to accomplish it. These areas are based on rebuilding the slopes from the bottom and do not take into account a cut /fill method where you would cut the top of the slope off and use that material to build the bottom After looking this over and you have time to decided how you want to do the grading, we can redraw the slopes using a cut /fill method at will tell you how far back from the top of the existing slope you have to go to cut enough material to lay them back to 4:1. What ever we come up with for the final I'll send Anne the Autocad base when it is done. If you need more information of have any questions give me a call.
