MANAGEMENT OF TEMPORARY SURFACES <br />The primary goal of temporary surface management is the control <br />of soil erosion, the protection of other resources such as air and <br />water quality is secondary. Management techniques to be applied <br />are mechanical (i.e. roughening surface, mulching, contouring), <br />chemical (soil adherents, lignin sulfonate), or biological <br />(temporary vegetation). <br />Temporary quick-growing vegetation may be used to protect these <br />surfaces from wind and water erosion and from noxious weeds. <br />A cover crop, such as annual rye or the temporary seed mix shown <br />in Table E-7 may be used, depending upon the length of time that <br />the area is to remain undisturbed. <br />REVEGETATION MAINTENANCE <br />• On areas previously reclaimed there may be small areas where <br />reclamation is not adequate. Soil erosion may be controlled <br />through the use of mulch, matting, chemical stabilizers, or other <br />appropriate techniques. Gullies will be filed and stablilized. <br />Bare patches of failed planting will be prepared and replanted. <br />Where there is evidence of poor soil conditions, the area will <br />be retreated or the topsoil replaced as conditions dictate. <br />Attempts will be made to control noxious weeds during reclamation <br />by mowing, spraying or other appropriate methods. <br />EVALUATION OF RECLAMATION SUCCESS <br />Because final reclamation success will not be assessed until <br />several years after permanent revegetation of disturbed areas <br /> <br />E-43 <br />
