sistent with the econanic cutoff lines. In order to do this, the <br />highwall line is surveyed and marked to ensure that the equipment <br />operators do not exceed the economic stripping limits. In areas <br />where there is potential for the stakes to be destroyed by the <br />operators then offset stakes are used. <br />5.3.2.2 Construction of ~1~+++P^t Control System <br />Prior to surface disturbance the sediment control system <br />for the area is constructed. This can include the construction <br />of diversion ditches, collection ditches, sediment ponds and <br />culvert placement. <br />The diversion ditches are located upslope of the disturbed <br />area and are used to convey runoff away from the disturbed area. <br />These ditches aze usually located on steep hillsides and therefore <br />it is not practical to salvage topsoil prior to the construction <br />of the ditches. In the event the ditch traverses an area which <br />is not steep, topsoil will be bladed downslope and stabilized <br />and then the ditch will be cut into the hillside. <br />Collection ditches will be located downslope of the disturbed <br />area and will be used to collect runoff from the disturbed area <br />and direct it to the sediment pond. In view of the fact that <br />these ditches will be near the disturbed area, topsoil will be <br />salvaged and later used in the reclamation of the ditches. <br />The construction of new sediment ponds will occur in <br />the following ma^^or: emUanlamnt and pool boundaries located; <br />woody vegetation, if p*-P~^t, grubbed; topsoil relmved from embarilvrn~t <br />and pool area; embankment created using fill frtan pool area if <br />possible, otherwise fill will be hauled in from the developing pit; <br />V-8 <br />
