APPENDIX 2.05.3-7 (Continued) <br />• <br />Two C-factors are used. For the first year of reclamation, it is assumed <br />that cover is provided by 1500 lbs/acre of mulch, even though it is anticipated <br />that a more protective cover crop will, in fact, be established. <br />For the following years, the cover factor assumes a low ground cover (20 <br />percent grasses) to accommodate the possibility of grazing by the landowner, <br />even though this is specifically restricted in the reclamation plan. No <br />P-factor is assumed, although the reclamation operations are expected to include <br />some contour plowing for seedbed preparation. <br />The results of this sediment analysis are as follows. <br />U <br />R <br />1st year r3~ <br />2nd-10th Year 130 x <br />K ~ LS ~ C <br />x ~~ <br />.18 x 12 x .20 x <br />P I = A <br />i`T~5.5b T ate. <br />1 = 12.96 T/ac/yr. <br />For the watersheds to have runoff impoundment or diverted, including areas <br />• <br />A, B, C, and D .shown on Map 11, Tables 1 and 2 of Appendix 2.05.3-7 show the <br />watershed size, the sediment delivery ratio for a watershed of this size, and <br />the sediment yielded for both a single year and for the life of the surface <br />impoundments (10 years). <br />- 256 - <br />(Rev. 5/86) <br />
