For P, support practice, a value of 0.9 can be used with track -walking up and down slope <br />(Page 5.24, [Goldman, 1986]). <br />The annual soil loss analysis for NCRCSL with the above factors is tabulated below for the two <br />prevalent slope conditions for the proposed Final Grading and Drainage Plan: <br />Slope Area <br />R <br />K <br />P <br />I L <br />S <br />Bare Soil (Unprotected) <br />Vegetated Soil (Protected <br />LS <br />C <br />A(Tons/Acre) <br />LS <br />C <br />A(Tons/Acre) <br />0'21 <br />Side Slopes <br />20 <br />0.9 <br />150 <br />33% <br />8.5 <br />1 <br />32-40 <br />6.8 <br />0.05 <br />1.3-1.6 <br />0.26 <br />0.21 <br />Plateau Areas <br />20 <br />0.9 <br />600 <br />5% <br />1 <br />1 <br />4-5 <br />1 <br />0.05 <br />0.2 <br />0.26 <br />The annual loss of protected soil for NCRCSL, after vegetation is established, is calculated to be <br />0.2 tons per acre per year for the top deck areas, and about 1.6 tons per acre per year for the <br />perimeter slopes. Both values are below the EPA's accepted value for completed landfills. <br />Attachments: From Handbook 703: Figure 2-3 <br />Figure 3-1 <br />Tables 4-1 and 4-3 <br />References: <br />Goldman, Steven, 1986, Erosion and Sediment Control Handbook. <br />U,S.
