Adapted from PennDOT Compost shall meet the standards in Table 4.2. STANDARD CONSTRUCTION DETAIL #4-2 Compost Filter Berm Compost filter berms shall be placed at existing level grade. Both ends of the berm shall be extended at least 8 feet up slope at 45 degrees to the main berm alignment (see Figure 4.1). The maximum slope length above a compost filter berm shall not exceed that shown in Table 4.4 for the standard silt fence (18” high fence). Tall grass shall be cut prior to installation to minimize potential for undercutting. Berm shall be netted or otherwise anchored after installation. Sediment shall be removed when accumulations reach 1/3 the aboveground height of the berm. Any section compost filter berm which has been undermined or topped shall be immediately replaced. Concentrated flows shall not be directed toward any compost filter berm. 363-2134-008 / March 31, 2012 / Page 68
Installation - Compost filter berms may be installed by hand, by using construction equipment (e.g. backhoe, wheel loader, or skid loader), or with specialized equipment such as a pneumatic blower or side discharge spreader with a berm attachment. The compost should be uniformly applied to the soil surface, compacted, and shaped into a rough trapezoid. Filter berms may be installed on frozen or rocky ground. Heavy vegetation should be cut down or removed to ensure proper contact with the underlying soil surface. Vegetated berms may be seeded by hand, by incorporating seed into the compost prior to installation — a typical procedure when installed by pneumatic blower or mixing truck with side discharge — or by hydraulic seeding after berm construction. WEIGHTED SEDIMENT FILTER TUBE - Sediment Removal Efficiency: MODERATE. This device is an ABACT for HQ but not EV watersheds. Weighted sediment filter tubes are tube-shaped devices filled with non-biodegradable filter materials for longevity and reuse. They may be used to control runoff from small disturbed areas where silt fence would normally be used as well as certain locations where a silt fence is not typically effective (e.g. above headwalls and endwalls). In general, the maximum slope length for standard silt fence may be used for 12” diameter tubes and slope lengths for reinforced silt fence (Table 4.4 or Figure 4.3) may be used for 18” to 20” diameter tubes. However, longer slope lengths may be considered by the Department on a case-by-case basis. The tubes can also be used instead of rock filters or as filters for storm sewer inlets located in sump areas. Standard Construction Details # 4-3 through # 4-5 may be used for weighted sediment filter tubes installation and maintenance. When the area tributary to a tube has been stabilized, an undamaged tube may be removed and used at another location. ACF Weighted sediment filter tubes may be placed in areas of concentrated flow in lieu of rock filters if installed according to manufacturer’s recommendations or Standard Construction Detail # 4-4. Weighted sediment filter tubes may not be used in lieu of protective liners in constructed channels. Where flow path widths exceed the length of one filter tube, Standard Construction Detail # 4-5 should be used. 363-2134-008 / March 31, 2012 / Page 69
