Exhibit C <br />Mining Plan <br />Mining Plan: <br />1. Mining of Sand and Gravel deposits started in 1996 and will end in June 2020. <br />The site consists of 9.03 total acres with an anticipated total mining area of 5.64 <br />acres. <br />2. Topsoil depth is approximately 6", which is a grayish brown loamy sand. Topsoil <br />has been stripped and stock piled to build up a building pad for a residential house <br />and shop. Future stripped topsoil will be stock piled as shown on Exhibit C. All <br />future topsoil will be graded with side slopes no steeper than 3H:1 V, with suitable <br />seeding of graded area to prevent erosion. <br />Thickness of the sand and gravel deposit ranges from ten to thirty feed in <br />thickness. <br />4. An access road has been constructed from CR 16 to the sand and gravel pit. <br />5. The pit will be operated as an open pit with no de-watering or discharge to the <br />South Platte River. <br />6. The open pit does intercept groundwater all year, and a Substitute Water Supply <br />Plan has been requested from the State Engineer (enclosed). In addition, the <br />depletions associated with the open mining will ultimately be included in the <br />Logan Well Users Decree 03CW195. <br />7. No refuse, acid or toxic-producing materials will be exposed or used on the <br />mining site. <br />8. Reclamation will be consistent with the future land use including wildlife habitat <br />and the existing residential house and shop area to the south. <br />9. All sand and gravel will be stockpiled on site for use in concrete, barrow material <br />and road base. There will not be any screening, separation or crushing activities <br />of the mined aggregate.
