2. Do not allow the saturation of topsoil with water. 3. Do not use plastic covering. Maintenance Inspect stockpiles regularly,especially after large storm events. Standards Stabilize any areas that have eroded. is • Establish soil quality and depth toward the end of construction and once established,protect from compaction, such as from large machinery use, and from erosion. Plant and mulch soil after installation. • Leave plant debris or its equivalent on the soil surface to replenish organic matter. • Reduce and adjust,where possible, the use of irrigation, fertilizers, herbicides and pesticides, rather than continuing to implement formerly established practices. BMP C126: Polyacrylamide (PAM) for Soil Erosion Protection Purpose Polyacrylamide(PAM) is used on construction sites to prevent soil erosion. Applying PAM to bare soil in advance of a rain event significantly reduces erosion and controls sediment in two ways. First, PAM increases the soil's available pore volume, thus increasing infiltration through flocculation and reducing the quantity of stormwater runoff. Second, it increases flocculation of suspended particles and aids in their deposition, thus reducing stormwater runoff turbidity and improving water quality. Conditions of Use PAM shall not be directly applied to water or allowed to enter a water body. In areas that drain to a sediment pond, PAM can be applied to bare soil under the following conditions: During rough grading operations. • In Staging areas. Balanced cut and fill earthwork. • Haul roads prior to placement of crushed rock surfacing. Compacted soil roadbase. • Stockpiles. After final grade and before paving or final seeding and planting. • Pit sites. Vohnne 1I—Construction Storinwater Polhaimi Prei,ention-August 2012 4-32 is
