BLM East Gmvel Pit <br />Mining Method to be Employed: <br />Exhibit D <br />Mining Plan <br />The BLM East Gravel Pit was fast entered by the County in July 1974, to provide a source of sand and <br />gravel for the county road construction and maintenance within the vicinity of the pit. <br />The maximum disturbed area of the pit shall be approximately 30 acres, with an excavation depth to be <br />approximately 20' at a maximum. The overburden stockpile at present prior to conversion is <br />approximately 9,000 yds, with an expected overall stockpile at the end of mining to be 41,300 yds. The <br />topsoil stockpile at present is approximately 3,300 yds. With and expected overall stockpile a[ the end of <br />mining to be 19,500 yds. Approximately 4,700 yds will be hauled in to complete reclamation. <br />As indicated on the attached plans, it is proposed to continue the extinction of sand and gravel deposits in a <br />northeasterly direction. Topsoil and overburden materials will be stockpiled in the mined out pit azea as <br />indicated. L`deemed necessary by BLM personnel, Jackson County will stabilize the topsoil stockpile with <br />suitable vegetation. <br />Ginvel deposits will be excavated to maximum depth of 20 feet utilizing Dozers and/or frontcnd loaders <br />and side slopes of the pit will be maintained at 3 or 4:1. Operations and stockpiled material will be <br />restricted from the edge or rim of the mesa top as to provide a natural screening of the pit. I[ is estimated <br />that approximately 25,000 cubic yazds of sand and gravel materials will be removed annually during the <br />next ten{10) years. <br />Access to the proposed BLM East Gravel I'it will be afforded by an existing constructed road from Jackson <br />County Road # 12D. It is not anticipated that any additional road constmction will be required for this <br />county opeintion. <br />This site will be kept free of all trash, waste material, garbage, and rubbish at all times. All refuse will be <br />disposed of in the Jackson County Sanitary Landfill. <br />Jackson County will carry on all operations in a workmanlike manner, having due regard for [he safety of <br />employees; and shall safeguard with fences, barriers, fills, covers, or other effective devices, pits, cuts, and <br />other excavations which otherwise would unduly imperil the life, safety or property of other persons. <br />Surface or ground water is not anticipated to create any problem during opeintions <br />A steel gate with warning signs will be placed at the entrance to the pit to restrict access to unauthorized <br />personnel. The pit will be patrolled on a regulaz basis to inspect for damage and to remove litter and illegal <br />dumping. Jackson County Weed Control will control all noxious weeds. No inopeinble equipment or <br />equipment not related [o the mining operation will be stored at the site. <br />
