Exhibit D—Mining Plan <br /> This pit is already in operation.As such,the haul road is already constructed. <br /> Topsoil is minimal in this area and would range from two to zero inches deep.This will be scraped from <br /> the surface using loaders and piled in a manner along the boundaries of the pit area.This will be seeded <br /> to prevent erosion. <br /> No overburden is expected in this operation as the sand and gravel are readily available at the surface. <br /> The sand and gravel has historically been surface to approximately ten to fifteen feet deep in this <br /> operation. <br /> The pit excavation will be twelve to fifteen feet in depth in the center with ratio of up to 3:1 sloping to <br /> the edges.This slope will be maintained throughout the operation. <br /> The mining operation will continue in a southern direction from the existing affected area.The mining <br /> will be done in approximately five acre increments throughout the additional ten acres. Each five acre <br /> area will be in operation for approximately 10 years, adding another 20 years to the operation.As this <br /> mining occurs,two of the three fences will be affected as well as a portion of the ranch road.There is no <br /> plan to relocate or replace the fence at this time as no cattle are in the area. <br /> The mining will occur with loaders and backhoes scraping any usable topsoil and placing it in a stockpile. <br /> This stockpile will be vegetated and maintained in a manner consistent with DRMS regulations. <br /> The sand and gravel will then be removed with loaders and hauled out of the area of operation with <br /> belly dump style trucks. <br /> This operation should not create water diversions or impoundments. Rainfall in this area is minimal.All <br /> rainfall should be easily absorbed by the high sand and gravel content of the pit area. <br /> The mining will be intended to collect the sand and gravel that this area has historically consisted of. <br /> This operation should not contain secondary commodities. <br /> The sand and gravel that will be collected in this operation will be used for maintenance of existing and <br /> the building of new county roads. It may be mixed with a small stockpiles of millings that is brought on <br /> site from external sources. <br /> No water will be used in this operation. <br /> No groundwater should be exposed in this operation. <br /> No explosives or chemicals will be used or stored on site in this operation. <br /> No secondary commodities are expected. <br />
