(e) Four topsoil stockpile locations are shown, two for Pit 1 and two for Pit 2, but all of them are in <br />Pit 1. Two of them are on the pit floor, and the other two are on sloped areas. Why are the Pit 2 <br />stockpiles in Pit 1, which will require longer haul distance to replace? <br />(f) The eastern topsoil stockpile for Pit 1 is on a slope that will not be mined, as indicated by the <br />contours. Please note that topsoil that erodes from this area and goes downhill will leave the <br />permitted area. Please show the runoff and sediment controls, for this slope and throughout the <br />permit azea. <br />(g) The western topsoil stockpile for Pit 1 is on a mined slope, though it is not clear at what point <br />during the operation it is to be placed there, eg., is it after the area is mined or before? <br />Please note that several of the questions above may require additional narrative in the Mining Plan <br />(Exhibit D) as well as revisions to this exhibit. <br />Exhibit D -Mining Plan (Rule 6.4.4) <br />Your plan states that the 3:1 slopes and the 1:1 slopePoench areas will be constructed during the <br />mining of those areas. The topsoil replacement on the slopes and benches is unclear. Please describe <br />the topsoil replacement on the benches: Is it to occur before the next lower bench is constructed? <br />Please describe the topsoil replacement on the 3:1 slopes: How will it be carried up and spread, since <br />stockpiles are generally below the slopes? <br />Since mining will not include blasting, the rock is presumed to be fractured enough to excavate with a <br />ripper or hydraulic hammer. As such, if the 1:1 slopes resulting from mining are not found to be <br />stable, then the slope gradient will have to be decreased. Are there existing 1:1 slopes on the site, that <br />appear to have remained stable during mining under this permit? Is there an engineering evaluation <br />of the rock stability? Your response may be included under this exhibit or under Geotechnical <br />Stability -Rule 6.5. <br />Please describe whether the benches are to be sloped into or away from the wall, and whether a low <br />berm-type structure will be used to catch raveling rock. <br />The plan states that mining will proceed from north to south, but it should be more specific, since it <br />may be more complicated due to the existing disturbance as well as the proposed sloping, benching, <br />stockpiling and gulch corridor. <br />The application includes many pages of soil descriptions, but no clear figure stating what depth of <br />topsoil will be salvaged. Please provide the depth, and clazify if it is an average, a minimum or a <br />range. <br />The responses you provide will assist in a better calculation of the bond amount. <br />Exhibit E -Reclamation Plan (Rule 6.4.51 <br />Please describe when and how the benches will be revegetated, eg., will it be done while accessible to <br />tractor-drawn seeder, or broadcast manually, after the next lower bench is begun? (This is related to <br />the question above concerning when and how topsoil will be spread on the benches.) <br />There are topsoil stockpiles along the north of the existing pit, but are not part of the mapped <br />stockpiles or included in the description of respreading the soil. Will the stockpiles be moved, or be <br />respread? <br />The responses you provide will assist in a better calculation of the bond amount <br />
