If pit <br />dewatering operations are required, Cotter will comply with the terms and conditions of <br />the National Pollutant Discharge Elimination System permit for the JD -7 underground <br />mine <br />E.5 Topsoil and Re- vegetation <br />E.5.1 Topsoil <br />Referring to Exhibits C, D and F the open pit will be mined using conventional surface <br />mining equipment such as scrapper, dozers and graders. The topsoil from the semi -arid <br />loam flats was removed to a depth of 20 to 60 inches and stockpiled (Figure J -1). A <br />temporary vegetative cover was established on topsoil stockpiles to minimize wind and <br />water erosion and to maintain organic matter in the soil. Where practicable, woody <br />vegetation will be removed from the site and put to a beneficial use such as firewood by <br />BLM. <br />Some woody vegetation will be piled and left near the site perimeters for use by small <br />animals for cover (see Exhibit I). The overburden will be removed and deposited as <br />depicted in Figures D.5.1 — D.5.11 (Table E.5 -1). Stability of the overburden stored will <br />be insured by a combination of the effects of natural settling and the weight of the <br />earthmoving equipment. <br />Final contours in the reclaimed pit will be approximately 2:1 (horizontal to vertical) <br />slopes and will blend with surrounding topography. When the topsoil is replaced, it will <br />be graded to an average depth of 10 to 14 inches. <br />E.5 -1 Top Soiling Schedule <br />(Thousands of Yards) <br />E -3 <br />
