The sediment <br /> pond will be used for pit dewatering purposes as mining will take place below the water table. Water <br /> from the pit bottom will be pumped to the sediment pond for sediment settling. The water will either <br /> infiltrate or evaporate prior to release after 72 hours to the permitted discharge point. The discharge <br /> point diverts water through a 20" culvert under the county road to a small ditch. The pit dewatering <br /> system is shown on Map C-2 and has already been constructed as of September 2023. More <br /> information on hydrology is located in the existing permit's Exhibit G, and should be unchanged <br /> from this revision. The active pit will serve as the sediment pond in the case of a large storm event. <br /> The site is accessed by an easement from 1800 Road. This road will be retained after reclamation <br /> for the easement owner, Teddy Graff. Therefore, this road does not need to be included in the <br /> permit area. Documentation of this agreement has already been submitted to the Division in the <br /> existing permit. The access is shown on Map C-2. <br /> No toxic or acid-producing materials will be encountered by mining. If any are encountered, it will be <br /> covered with overburden and/or topsoil, and the mining plan will be adjusted to avoid these <br /> materials. <br /> 2. Mining Timetable <br /> Mining operations at the Anderson Pit are anticipated to take 36 years since the start of mining in <br /> May 2005. As of 2023, there is an estimated 18 year mine life remaining. This may vary based on <br /> the rate of mining which is dependent on demand for the aggregate products. The permitted <br /> production level is 378,750, however, actual production levels will tend to be around 252,500 tons <br /> per year. <br /> Table D-1 - Mining Timetable shows the mining sequence and the amount of time for each step. <br /> Table D-1 - Mining Timetable <br /> Description Time Required <br /> Initial stripping of new mining areas. 1 month (repeated throughout the mine <br /> life as new mining areas are opened) <br /> Mine and reclaim pit according to approved plans. 18 years <br /> Reclamation occurs as mining has reached its <br /> maximum extents in an area. <br /> Total 18 years <br /> Anderson Pit <br /> September 202 D-2 Lewicki&Associates <br />
