9. The applicant states that the pit will be mined in three phases. Please indicate these <br />phases on the exhibit(s), note the direction of mining and state the size of area to be <br />worked at any one time. <br />A map showing the approrimate location of the three phases is attached. As we <br />discussed on site, phase 3 may never be mined if sufficient material exists for the <br />project in the other portions of the pit. <br />10. Rule 3.1.9(3) requires that topsoil stockpiles be stored in places and configurations to <br />min;mi~P erosion and be located in areas where disturbance by ongoing operations will <br />be minimized. In accordance with Rule 3.1.9(1), topsoil and overburden must be <br />segregated and stored separately. Please revise the exhibits to depict the location of the <br />topsoil piles. <br />Topsoil stoclgPiles wilt be built in the most convenient areas to be oat of the way <br />during mining. The approximate location of the stockpiles is shown on the attached <br />map. Mr. Orr plans primarily to posh the topsoil to the outside edges of the pit <br />boundary on the north and the west as that area is mined. Topsoil will not be stored <br />with other overburden at the site. Since much of the material will be used for <br />building roads, little to no overburden is anticipated <br />11. Please inform the Division as to how topsoil piles will be protected to prevent wind <br />and water erosion to include the dimensions of the piles sad a temporary seed mixture. If <br />a seed mixture is proposed, please stet the rate in PLS/acre, application method and <br />timing of seeding. <br />Topsoil stockpiles will be seeded with grass seed after a sufficient pile is in hand to <br />require cover. The species recommended by the NRCS by phone was brome grass. <br />The seed will be broadcast and sown daring the months of November through <br />March. <br />12. The applicant notes that the pit is adjacent to a gravel pit operated by Logan County <br />Road and Bridger (the Schumacher Gravel Pit, Pennit No M-1995-063). Please state <br />howmining and r~lamation plan will impact the Logan County Pit. In particular, please <br />state if the pits will eventually join, or will be separated by a set buffer distance. <br />The Schumacher #3 Pit will have little to no impact on the Logan County Pit The <br />boundaries of the two pits do butt up against each other. As agreed at the on-site <br />visit, the area between the two permits will be mined through, rather than leaving a <br />slope on our south boundary and one on their north boundary. This is Mr, Jeff <br />Schumacher's desire. He is the Iand owner of both pits. A revised "Snal rnntonr <br />map" reflects this change. Previous information from the Logan County Pit permit <br />file indicated that a pipeline was in existence immediately north of their pit, bat Jeff <br />Schumacher has informed us that that pipeline has been removed. <br />4 <br />
