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