<br />~~ <br />• DIVISION OF MINERALS Fc GEOLOGY BOARD PERM1"1' APPLICATION <br />REG(ILAR OPERATION (112) <br />PROJECT NAME: HOGUE/RIVEK PIT <br />Pad e ii <br />EXHIBIT D - ~IINING PLAN <br />7. Water diversions wil] be constructed in connection with <br />perimeter trench drains and dewatering systems. Inferior <br />water diversions may be required for site drainage. A <br />100-foot "no work zone" will be preserved between the pit <br />and the Yampa River. Pampa Fiver flows will not be <br />affected. <br />A water impoundment will be created after pi[ excavations <br />are completed and the dewatering system is terminated. <br />Small water impoundments may also be created at the <br />settling ponds used for dewatering operations. These areas <br />may be utilized for wetlands construction by backfilling <br />with overburden or unsuitable material and covering the <br />material with topsoil and/or existing wetland dredge. <br />6. Basic phasing of mine operations is subject to the approval <br />of [he owners. Phase planning is designated to meet the <br />requirements set forth by Mr. Hogue and the Hogue Ranch as <br />well as utilize the gravel reserves on this property. <br />9. The project is proposed to consist of four main phases of <br />mining operations. <br />Phase I operations will begin at the existing pond. <br />' Phasing and operations will expand to the west to include <br />approximately 38 acres that will be affected by mining <br />operations. Mining is expected to take approximately 20 <br />years to complete. A pond approximately 25 to 30 acres in <br />size will be created from mining operations. <br /> SIZE WETLANDS EXT.
