E -5 RECLAMATION OF FACILITIES <br />E -5.1 RECLAMATION OF ROADS <br />• • <br />Roads represent a portion of the total area to be disturbed for the Rock School Lease Project. <br />Erosion and sediment controls will be implemented during construction, operation, and reclamation <br />phases to ensure that adverse environmental impacts from roads are minimized. <br />In the construction phase, silt fences, straw bales, and /or check dams may be used to control <br />erosion and sedimentation. At crossings of ephemeral drainages, erosion and sedimentation will be <br />controlled by installing culverts properly sized for the anticipated flow or by using durable surfacing <br />materials with or without culverts. <br />During operational use, roads will be constructed following prescribed specifications for the <br />intended usage. Road specifications will require adequate crowning or sloping to ensure positive <br />drainage from the traveled surface and will provide adequate erosion and sedimentation control <br />structures and practices to safely convey water runoff away from the roads. During a road's <br />operational life, maintenance activities will be performed to ensure that proper surface <br />configurations are maintained. Where required, surfacing will be of adequate thickness and of <br />durable materials capable of supporting the types and amounts of traffic expected. <br />Roads will be provided with drainage systems which are capable of safely carrying runoff from <br />roads into undisturbed drainage channels or to areas where erosion will not occur. Road drainage <br />systems will typically include the use of features including ditches, berms, diversions, channels, <br />water bars, and culverts. Each of the drainage features will be properly sized and installed for its <br />particular use to ensure efficacy. Channel linings in road drainage features will be specified and <br />placed as necessary to control erosion and sedimentation and to protect the drainage feature. <br />These channel linings may include soil, vegetation, synthetic materials, and rock rip -rap which may <br />be used singly or in combination. Inspection and maintenance of road drainage features will be <br />performed on a regular basis and following substantial runoff events to identify and correct problem <br />areas. <br />Water bars may be used to protect roads from erosion during operational use and during restoration <br />and reclamation. When possible, water bars will be located to take advantage of local topography. <br />Outlets of water bars will avoid loose fills and will discharge to stable areas whenever possible. <br />Water spreaders will be used at the outlet ends when necessary. Water bar spacing on roads will <br />be based on road slope and erosion hazard and will generally conform to the following: <br />G.ILM M78545 .007Rectamation1Redamexh.DOC <br />E -6 <br />
