适用范围
This specification covers compost produced from various organic by-products for use as a filter berm media for erosion/sediment control. The technique described in this specification is primarily used for temporary erosion/sediment control applications where perimeter controls are required or necessary. This technique is appropriate for slopes up to a 2:1 grade (horizontal distance:vertical distance) and on level surfaces and should only be used in areas that have sheet flow drainage patterns (not areas that receive concentrated flows). The filter sock technology is appropriate for areas outlined in Section 1.2 as well as areas of high sheet flow erosion@ around inlets@ and in other disturbed areas of construction sites requiring sediment control. Unlike filter berms@ the filter sock technology may be used in areas that have concentrated flow drainage patterns@ up to 10 gallons per minute per linear foot of filter sock.
