Two valley fills and two temporary overburden stockpiles were approved for the South Taylor <br />area in PR -02. The permanent fills are the West Taylor Fill and the East Taylor Fill. The <br />temporary overburden stockpiles are TS West and TS East. The information on the new valley <br />fills is contained in Permit Volume 12 in Sections 4.09, 4.10, 4.11, 4.12 and 4.13. <br />The West Taylor fill is a valley fill located in the upper west fork of Taylor Creek. The final <br />configuration will contain approximately 10 million cubic yards of material from the initial box - <br />cut for the South Taylor Pit. The fill is approved to have a durable -rock drain built by gravity <br />sorting of dumped overburden materials. CCC is approved to use terrace ditches to divert water <br />off of the face of the fill and to the relief drains on the side. Additionally, 100 -year diversion <br />ditches route clean -water around the fill. Upon completion of the West Taylor Fill, the area will <br />have the topsoil replaced and will be revegetated per the approved reclamation plan. <br />The East Taylor Fill is a valley fill that located in the upper east fork of Taylor Creek. The final <br />configuration will contain approximately 50 million cubic yards of material from the initial box - <br />cut for the South Taylor Pit. The fill is approved to have a durable -rock drain built by gravity <br />sorting of dumped overburden materials. CCC is approved to construct terrace ditches to divert <br />water off of the face of the fill and to the relief drains on the side. Additionally, 100 -year <br />diversion ditches route clean -water around the fill. Upon completion of the East Taylor Fill the <br />area will have the topsoil replaced and it will be revegetated per the approved reclamation plan. <br />Temporary overburden stockpile TS West will be located on the top of the East Taylor Fill, in <br />the upper east fork of Taylor Creek. Engineering designs were submitted to verify the stability <br />of the East Taylor Fill with the additional fill material. Upon the completion of mining in the <br />South Taylor Pit, the material from TS West will be returned to the pit using a truck/shovel <br />operation. The surface (which is the surface of the East Taylor Fill) will then be completed as <br />described above. <br />Temporary overburden stockpile TS East will be located on an area that once was part of the <br />Section 16 Pit. Upon the completion of mining in the South Taylor Pit, the material from TS <br />East will be returned to the pit using a truck/shovel operation. The surface will then be regraded, <br />topsoil will be replaced and the fill will be revegetated in accordance with the approved <br />reclamation plan. <br />No permanent excess spoil is anticipated or approved for the mining and development of the <br />Collom Pit. One temporary overburden stockpile is proposed for the Collom area in PR -04. The <br />temporary spoil stockpile will be located in portions of Sections 25, 26, 35 and 36, T4N, R94W, <br />situated north of the Collom Pit. The Collom Permit expansion area is found to be in compliance <br />with Rule 4.09. Information on temporary excess spoil can be found in Sections 2.05 and 4.09 of <br />Volume 15. <br />PR -04, Colowyo Coal Mine C1981-019 49 August 2016 <br />
