EXHIBIT D mine plan INTRODUCTION -Elam Construction established a "year round" office in their present location at the Vagneur Gravel Pit in 1990 after gaining a local land use approval in 1988. The operation is located in the Woody Creek area of Pitkin County. Elam Construction, Inc. has conducted a sand and gravel business constantly since that time. The amended plan consists of continued gravel extraction, crushing, washing, asphalt and concrete production together with the stockpiling of imported soil, asphalt and concrete rubble. The predominate feature of the 104.6 acre Vagneur Gravel Pit site is extraction and processing of sand and gravel products. Exhibit C depicts the permit boundary, various mining activities, and the location of other uses ancillary to the entire operation. Specific activities which occur on the property include: MINING AREA -All of the overburden and topsoil has been removed from the 60 acre mining area and has been used for the construction of seeded berms along the westerly side of the mining area, along the haul route, and around the employee housing area. As areas are mined, the side slopes of the pit are graded to a 2 foot horizontal to 1 foot vertical slope and then seeded. Herbicides are applied annually to control weed growth. Setbacks between the mining area and the property boundary have been maintained to protect the integrity of the adjoining land. In 1990, gravel extraction began near the south end of the mining area and proceeded to the north boundary. Gravel extraction occurs in approximately 30 foot lifts and proceeds from north to south and then south to north. As of this date, one 30 foot lift of extraction has occurred across the mining area and the second 30 foot lift started at the northerly most point of the mining area in 1997. Past mining activities have shown that the nature of the sand and gravel resource to be a 80 foot thick alluvial deposit. LIFE OF MINING AREA -Several factors affect the total life of most sand and gravel operations. Most notable is the surrounding communities future gravel, asphalt and concrete needs. Other factors include:
