Mining Plan <br />BLM Pit -West of Maybell <br />A. Soil overburden will be removed from the portion of the pit to be excavated and stockpiled for <br />later use when reclaiming the pit. if overburden is stockpiled longer than 1yr the stockpiled <br />overburden will be graded and seeded. The materials beneath the over burden material will be <br />excavated and mined with typical construction equipment. The usable sands and gravels will be <br />removed and used offsite. <br />B. Earthmoving will be accomplished with typical excavation construction equipment including <br />excavators, front end loaders, and dump trucks. The usable excavated materials will be hauled <br />offsite to be used for construction purposes. <br />C. A minor amount of water is anticipated onsite from precipitation. A soil berm will be placed at <br />the upper portion of the perimeter to reroute any possible offsite flows from entering the site. <br />All onsite precipitation will diverted offsite via existing drainage paths. Onsite water usage will <br />be minimal. <br />D. An area up to an acre in size will be excavated at one time. Other areas may be used for <br />stockpiling and crushing operations. <br />E. The mining sequence is anticipated to begin at the southern portion of the pit and continue <br />north. An approximate completion date is dependent on the materials needed. It is anticipated <br />that a small portion of the pit, up to one acre, will be mined at a single time. Each portion is <br />anticipated to take an entire year. The process will include removing and stockpiling all topsoil. <br />Once topsoil is removed the gravels will be removed for offsite use. After gravels have been <br />removed the reclamation process will begin. This entire process is anticipated to take an entire <br />year but if the mining process stalls or is extended the stockpiled topsoil will be graded and <br />reseeded until needed for reclamation. <br />F. The overburden will be removed up to a full maximum depth of 6 inches. The material to be <br />mined consists of sands and gravels used in roadway construction. The excavation depths will be <br />a maximum of 20 feet with maximum 3:1 slopes. Below the excavated material likely consists of <br />wet gravely sands above gravely cobbles. <br />G. The materials to be mined are the sands and gravel materials. The materials will be sorted, <br />stockpiled and hauled from the site. The final use of the material is road construction. <br />H. No incidental products are anticipated to be mined onsite. <br />1. No explosives will be used onsite. <br />
