Mining will begin in the Phase One area as shown on the accompanying Mining Plan Map. <br />First, topsoil will be removed to its' full depth (12" or less) and stockpiled on the south and east <br />perimeter of the area to be mined. This stockpile will be in the shape of a berm approximately 4 feet in <br />height and 15 feet wide at the base. The berm will be seeded with a grass mixture approved by the Soil <br />Conservation Service and mulched with straw. Seeding and mulching will be done mechanically with a <br />broadcaster attached to a 4 wheel UTV. <br />After the soil stockpile is finished, mining will begin in the southeast corner of the Phase I area and <br />proceed westerly and northerly. The pit will be excavated with bulldozers and the material will be fed to <br />a portable crusher and screen plant for processing by rubber tired bucket loaders. Side slopes will not <br />exceed 3:1 and there will be no highwalls. The pit will be excavated to a depth of approximately 40 feet <br />or 7880 feet above Mean Sea Level. In no case will mining occur at or below the groundwater surface. <br />After the material is processed into various products ranging from road sand to W minus gravel to 3" <br />minus road base, it will be transported to either a concrete batch plant or asphalt hot plant located as <br />shown on the accompanying Mining Plan map. <br />Some of the material will be hauled directly off the pit to the County Road for transportation to the <br />intended customer. <br />Each phase of this pit is expected to last about 2 years, with Mining commencing in January 2014 and <br />ending in December 2027. After mining is completed in each phase, the accompanying reclamation plan <br />will be implemented, phase by phase. <br />Mining Plan Time Table <br />Phase # <br />Time Span <br />Phase I <br />2014-2015 <br />Phase U <br />2016-2017 <br />Phase III <br />2018-2019 <br />Phase IV <br />2020-2021 <br />Phase V <br />2022-2023 <br />Phase VI <br />2024-2025 <br />Phase VII <br />2026-2027 <br />Summit Engineering Job Number: 1707122CE 17 <br />719-589-6147 <br />Alamosa, CO <br />
