COR-030000 Stormwater Management Plan <br />and 2E). BMPs may also be installed immediately prior to the start of activities where they S <br />will control erosion and sedimentation due to site disturbance. Surface activities will <br />continue; until final site reclamation and mine closure has been completed. BMPs will <br />remain until final reclamation is completed and final stabilization is achieved. <br />For a description of specific BMPs to be used, see Section 3 - Stormwater Management <br />Controls. <br />c) Disturbed area (§I.C.l.c): <br />The approximate areas that are disturbed during the mining process are as follows: <br />Sunday Mine: <br />Mining operations 33.0 acres <br />Total site area 40.62 acres <br />St. Jude Mine: <br />Mining Operations 9.7 acres <br />Total site area 10 acres <br />Topaz Mine: <br />Mining operations 8.3 acres <br />Total site area 12.85 acres <br />West Sunday Mine: <br />Mining operations 10.0 acres <br />Total site area 12.1 acres <br />Carnation Mine: <br />Mining operations 9.76 acres <br />Total site area 9.76 acres <br />The estimated total area of the site is 83.23 acres, of which about 70.76 acres will be <br />disturbed. <br />d) Soils (§I.C.l.d): <br />A soils report was not available for this project. The soils within the project are identified as <br />silty clay loams with bouldery and cobbly areas that are typical for this area (NRCS 2007) <br />and do not have an increased potential for erosion and sedimentation. The Bodot, dry-Ustic <br />Torriorthents complex consists of moderately deep, well drained, slow to moderately low <br />permeable soils. Bodot soils are formed on terraces, structural benches and landslides and <br />have slopes of 5 to 50 percent in this area. The Pinon-Ustic Torriorthents complex consists <br />of shallow, well drained, moderate permeability soils. Pinon-Ustic soils formed on hills and <br />ridges and have slopes of 5 to 30 percent in this area. Rock outcrops are also apparent on <br />slopes greater than 40 percent. <br />I? <br />Denison Mines (USA) Corp. Sunday Mines SWMP <br />3
