activities will be placed in a concrete washout pit. Signage indicating "Truck Washout <br />Area" will be placed at the concrete washout facility. If incidental washout, which is <br />discouraged, does occur on site, such as for the cleaning of concrete finishing hand tools <br />and wheelbarrows, the wash water will be disposed of inside the concrete washout <br />containment areas and allowed to harden. Hardened solids will be recycled. <br />5.3.8 Groundwater and Stormwater Dewatering <br />Any required dewatering of excavations shall be conducted in a manner that avoids <br />pollution and erosion. Any water from dewatering operations will be land applied and <br />allowed to infiltrate into the soil. Any water from dewatering operations shall not be <br />discharged into any waters of the State including wetlands, drainages, or storm sewer. <br />In summary, water from dewatering operations will not be discharged off the property. <br />6.0 POST - MINING AND POST- PROCESSING FINAL STABILIZATION AND <br />LONG TERM STORMWATER MANAGEMENT <br />The areas disturbed during mining and processing that are re- contoured to finished <br />grade will be stabilized in accordance with the permit's specifications as soon as <br />possible. Final stabilization will use a combination of roughening exposed slopes, <br />installation of rolled erosion control products (on slopes steeper than 3:1), seeding, <br />mulching and landscaping with sod, bedding plants, shrubs and trees. All erosion <br />control BMPs will be inspected and maintained until such a time the exposed soils have <br />been re- vegetated to 70 percent of pre- disturbance levels. After 70 percent re- <br />vegetation is achieved, all temporary erosion control measures shall be removed and <br />disposed of properly. Borrow area benches and walls will be re- contoured to a stable <br />configuration. <br />When it is not possible to permanently stabilize a disturbed area after earth disturbance <br />has been completed or where significant earth disturbance activities have ceased, <br />temporary stabilization measures such as surface roughening, mulching, application of a <br />tactifier, and / or temporary seeding will be implemented. All temporary stabilization <br />measures will be maintained until permanent soil erosion measures are implemented. <br />7.0 CONSTRUCTION ACTIVITIES INSPECTIONS <br />7.1 Minimum Inspection Schedule <br />Inspections will be conducted at least every 14 days. Post -storm event inspections must <br />be conducted every 24 hours or within 24 hours after the end of any precipitation event <br />producing the potential for erosion at the site. <br />Animas Glacier SWMP February 2012 <br />p. 17 <br />
