Gr.Yl1/8 /7 F <br />Reclamation Plan - Burros <br />Presently the only waste~g dumped on the surface is that belong- <br />ing to a third party leasing minerals from EP.DA and subject to reclamat <br />in through the terms of that lease. Union Carbide is responsible for <br />the other surface facilities used by the contractor in conjunction with <br />removal of this mineral. In the future UCC may again be extracting mineral <br />and [•raste, and depositing it on these properties. Current life of the <br />mina estimates are 10-15 years, therefore very little, if any, reclamation <br />xo^!~: can be done until cessation of mining activities. The surrounding <br />__.:.s 3r2 ~_',2.''. a5 vcPy rdn~•'13r:i and 4lildl!fe h?bltat, thcncfprc; the <br />reclamation choice is to return the "affected lands"to grazing and wildlife <br />va~ues. The r=_clamation gill be conducted in three phases. <br />I. Clean-up; t0 be completed within appror.imately two years <br />after permanent cessation of mining activity. This phase <br />wi'_1 require clean-up and removal of surface structures, <br />e:araneous debris and other removable surface facilities <br />fro;, the affected lands. The portal, ventholes and shafts <br />will be sealed or closed to prevent hazards and unauthcrized <br />entries. Cement pads and other permanent foundations c. ill <br />be removed or cover e,] >rith topsoil. <br />II. Earthmoving: to be cempleted within two years of permanent <br />cessation of mining activities. This phase will involve the <br />reoontouring of roads, cutbanks and dump surfaces to approxi- <br />mate e::isting contours and prepare a seeding surface. Dumps <br />containing sub-economical mineral values today are anticipated <br />to be of value in the future and therefore need to be ].eft in <br />such a manner as to make them accessible as conditions may <br />dictate. Crests of dumps :gill be rounded off to slope; of <br />14-25 degrees with berms at the edges to entrap run-off water, <br />sediments and natural seeds. Small berms and impoundments <br />will be placed on the surface in the appropriate drainage <br />direction to again entrap 'dater and sediments. 47here feasible, <br />cutbanks will ba blended into dump surfaces to match n<,tural <br />contours. Roads will be water barred at appropriate places and <br />cutbanks will be resloped where necessary. .411 surfaces will <br />be scarified to break the crust, and dragged. Our experience <br />indicates that eurfaces that are too smoothly prepared on slopes <br />are not effective in retaining moisture, sediments and natural <br />seeds. Therefore, it is best to leave small gouges and ridges <br />from cat tracks and blades. <br />
