7.1 . Surface Water Handling — Mining <br /> Surface water runoff will be handled the same way throughout the Mystic Soil's mine life: runoff <br /> within disturbed areas will stay in disturbed areas using berms and grading. Berms will prevent <br /> off-site discharge from entering the Soil Storage Area. The site road will be graded to drain into <br /> the Soil Storage Area. Grading of the site to drain internally, along with the buffers of <br /> undisturbed ground between the disturbed area and Lateral Forty-seven the Farmers Union <br /> Canal, will ensure that no sediment laden water enters the Lateral. Once surface water is <br /> collected within the mining pit, it will remain in the pit floor and be allowed to infiltrate. <br /> 7.1.1. Disturbed Area Runoff <br /> Drainage basin within the Mystic Soil site can be seen on Map C-2. Stormwater runoff data can <br /> all be found in Appendix G-1 in this exhibit. The results of those calculations can be seen on <br /> Map G-1. Mining and reclamation will not create additional drainage from the site. Baseline <br /> (Map C-1), mining (Map C-2), and reclamation (Map F-1) drainage basins and 100-YR runoff <br /> volumes are delineated on each map. Drainage direction is also delineated on each map. <br /> Sediment discharge will be controlled during mining by routing all discharge to the disturbed <br /> areas where it will infiltrate or evaporate. No discharge of sediment from the site will occur. <br /> Mystic Soil <br /> October 2022 G-5 Lewicki&Associates <br />
