1 <br /> ' thus increasing infiltration through flocculation and reducing the quantity of stormwater <br /> runoff. Second, it increases flocculation of suspended particles and aids in their depos- <br /> ition, thus reducing stormwater runoff turbidity and improving water quality. <br /> Conditions of Use <br /> ' PAM shall not be directly applied to water or allowed to enter a water body. <br /> In areas that drain to a sediment pond, PAM can be applied to bare soil under the fol- <br /> lowing 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 /> . Sites having a winter shut down. In the case of winter shut down, or where soil will <br /> remain unworked for several months, PAM should be used together with mulch. <br /> Design and Installation Specifications <br /> PAM may be applied with water in dissolved form. The preferred application method is <br /> ' the dissolved form. <br /> PAM is to be applied at a maximum rate of 2/3 pound PAM per 1,000 gallons water(80 <br /> mg/L) per 1 acre of bare soil. Table 11-4.1.9 PAM and Water Application Rates (p.301) <br /> ' can be used to determine the PAM and water application rate for a disturbed soil area. <br /> Higher concentrations of PAM do not provide any additional effectiveness. <br /> Table 1-4.1.9 PAM and Water <br /> Application Rates <br /> ' Disturbed Area (ac)PAM (bs)Water(gal) <br /> 0.50 0.33 500 <br /> 1.00 0.66 1,000 <br /> 1.50 1.00 1,500 <br /> 2.00 1.32 2,000 <br /> ' 2.50 1.65 2,500 <br /> 2014 Stormwater Management Manual for Western Washington <br /> ' Volume II- Chapter 4 -Page 301 <br />
