Box 116 <br />Kiowa, CO 80117 <br />303 - 621 -3157 <br />March 30, 2015 <br />State of Colorado <br />Attn: Ms. Amy Eschberger <br />Division of Reclamation, Mining and Safety <br />1313 Sherman Street, Room 215 <br />Denver, CO 80203 <br />Re: Permit No. M- 2001 -010 Allison Pit <br />Dear Ms. Eschberger: <br />Elbert County is requesting a change to the drainage at the Allison Pit, Permit No. M- 2001 -010. <br />Enclosed are four pictures from our Fondis Pit, Permit No. # M- 1988 -101 revised drainage. We <br />are looking at installing a similar drain in the Allison Pit, but eight feet wider. <br />Also enclosed are two maps describing the following: <br />• Point 1 — Shows the point at which the pit will be able to drain both ways. As we lower <br />the pit floor, we will not be able to drain out of the old drain, as it will not be low enough. <br />• Point 2 - Shows where the pit will drain when we lower the pit floor. This point may <br />vary depending on the depth we take the pit floor. <br />• Point 3 — Shows where we will remove two feet of dirt keeping a 10 -1 drop. <br />• Point 4 — Shows installation of concrete block with a layer of 5 " -12" rock on the back <br />side, allowing the water to slow down and spread out. <br />
