BLM East Gravel Pit <br />Mining Method to be Employed: <br />Exhibit D <br />Mining Plan <br />The BLM East Gravel Pit was first 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 />As indicated on the attached plans, it is proposed to continue [he extraction of sand and gravel deposits in a <br />northeasterly direction. Topsoil end overburden materials will be stockpiled in the mined out pit area as <br />indicated. If deemed necessary by BLM personnel, Jackson County will stabilize the topsoil stockpile with <br />suitable vegetation. <br />Gravel deposits will be excavated to maximum depth of 20 feet utilizing dozers and/or front-end 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. It is estimated <br />that approximately 25,000 cubic yards of sand and gravel materials will be removed annually. <br />Access to the proposed BLM East Gravel Pit will be afforded by an existing constructed road from Jackson <br />County Road # 12D. It is not anticipated that any additional road construction will be required for this <br />county operation. <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 the 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 operations. <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 regular basis to inspect for damage and to remove litter and illegal <br />dumping. Jackson County Weed Control will control all noxious weeds. No inoperable equipment or <br />equipment not related to the mining operation will be stored at the site. <br />All ground disturbing activities will occur within the top of the mesa, leaving an undisturbed 20 foot wide <br />(at the top) berm or "egg shell edge" around the entire pi[ perimeter, with excavation and processing <br />occuring within the berm. A berm of not less than 20 feet in width will be left undisturbed a[ the perimeter <br />of the permit area throughout the duration of mining operations. The "egg shell" shall serve as a visual <br />barrier and wind, runoff and erosion barrier during the life of the pit, until final reclamation occurs. At the <br />time of reclamation the berm shall be bladed in and used to reshape the mesa top. <br />Invasive weed treatment shall be conducted annually throughout the entire pit area, and shall include all <br />stockpiles. <br />As gravel pi[ expansion proceeds, topsoil and vegetation shall be removed together and stockpiled. The <br />stockpile shall be signed and kept distinct from subsoil's stockpiled for fill material. <br />All soil stockpiles shall be seeded and stabilized for the duration of the mining operation <br />All overburden encountered in mining shall be stockpiled for reclamation purposes. <br />
