In order to achieve the desired outcome, the reclamation contractor will undertake the following <br />steps in completing reclamation at each pond: <br />The pond will be dewatered, if necessary, to below the invert elevation of the corrugated metal <br />pipe dewatering device, which is generally in place at each pond. Any water pumped from a pond <br />will be passed through appropriate sediment treatment device, such as silt fence or straw bales, <br />prior to being discharged into receiving streams. <br />The corrugated metal pipe dewatering device will be excavated from the embankment. The sides <br />of the excavation will be no steeper than 2H:1 V. The slope of the base of the excavation will <br />mirror the gradient of the base of the corrugated metal pipe dewatering device, prior to its <br />removal. <br />Excavated dirt will be utilized on the outside face of the embankment, on the top of the <br />embankment, or it may be used as topsoil substitute on the inside slopes of the ponds. <br />The cut created during excavation of the corrugated metal pipe dewatering device will be used as <br />the principle spillway after reclamation is complete. Therefore, it will be lined with native rock rip <br />rap along the base and partially up the sides, as appropriate. <br />Wetlands species appropriate to site conditions will be planted azound the margins of each pond. <br />Revegetation of the pond embankments and of any other adjacent areas disturbed as a result of <br />reclamation construction will be accomplished following the completion of construction activities. <br />STORM WATER MANAGEMENT CONTROLS <br />No mining, milling or processing is being conducted at this site. Reclamation construction is the <br />only activity occurring at this site. Minimization of sediment delivery to adjacent streams as a <br />result of reclamation activities is the primary focus of this SWMP. As reclamation construction at <br />each pond azea is anticipated to be similar, the Storm Water Management Controls to be utilized <br />at each area are also anticipated to be nearly identical. Topographic conditions may dictate that <br />differing methods be implemented at any one pond <br />GENERAL <br />Most reclamation contractors use heavy equipment requiring periodic maintenance and fueling. <br />Division contractors are required to place berms azound any fuel tanks that they bring onto the <br />site. Used oil is contained in a designated area, and is transported off-site for proper disposal. All <br />project areas are kept in a neat and workman-like condition. <br />Pond Reclamation <br />Any water which is discharged from a pond prior to initiating reclamation construction will be <br />passed through silt fence or through straw bales prior to being dischazged into an adjacent <br />receiving stream. <br />
