MINING PLAN EXHIBIT D(CONT) <br /> stockpiles will be used throughout the year by the company. As <br /> mining ends on a section of the working face it is temporally <br /> graded to 2 : 1 so it is stable when there are no activities in the <br /> mine . Any resoiling and revegetation needed will be completed <br /> when the area where material is removed will not be redisturbed. <br /> This cycle continues until the mine is played out . <br /> Each time the mine is re-entered, mining begins by setting <br /> up the plant and if needed an area is stripped. The salvaged <br /> topsoil will be stockpiled along the mine perimeter setbacks or <br /> on the mine floor, i.e. , in places where it will not be disturbed <br /> until needed. Much of the permit area will continue to be used <br /> by the owners for their ranching purposes throughout the life of <br /> the mine . The approximate location of the soil piles are shown <br /> on the MINING PLAN MAP. <br /> Mining will begin on a section of the slopes created at the <br /> end of the last mining cycle until a near vertical face is open. <br /> This face will be worked to the east and west until it extends <br /> across the property and at that time mining will progress to the <br /> south or north depending on the Stage mining is taking place . As <br /> mining progresses thru the site the processing plant will be set <br /> near the open face to reduce the haul distance from the mine <br /> face . <br /> As mining progresses the plan is to begin to armor both <br /> sides of the embankment along the creek channel . The plan entails <br /> building the channel side as mining progresses when mining gets <br /> within 400 feet of the channel bank. When mining reaches the <br /> final dig line on the excavation side that section will be <br /> armored. In general, the toe of the armoring will be below the <br /> thalweg of the channel, so on the outside it will be 5 ft below <br /> and in the inside it will be 3 feet below. The material will be <br /> placed a minimum of two (2) feet thick. <br /> The armoring material to be used will be recycled concrete <br /> with all exposed rebar removed, that conforms to the definition <br /> of Inert Material, available to the Ellicott Sand & Gravel, the <br /> exterior slopes will be graded 2 . 5 : 1 and the inside slopes will <br /> be 3 : 1 . The size of the material will fall in the range of 12 to <br /> 36 24 inches with some larger pieces and intermixed with fines <br /> and will be placed below grade and on the inside it will be <br /> covered with material from onsite. Adequate quantities will be <br /> stored onsite, to complete the necessary armoring on any give <br /> 7(revised 10.31/19) <br />
