L <br />SEDIMENT POND CALCULATIONS <br />K Factor for Universal Soil Loss Equation <br />Torriorthents - Haplargids Complex <br />As this soil type is not listed in the Preliminary Guidance for Estimating Erosion, <br />and upon conversation with AI Spika of Soil Conservation Service in Delta, <br />Colorado, the Torriorthents Soil Type was compared ro Delson Very Stony <br />Loam for the use of the K Factor in the soil loss equation. <br />Thickness K T <br />0 - 8" .15 5 <br />• 8" - 42" .32 5 <br />42" - 60" .24 5 <br />As fhe lands upon which our mines are located are extremely rocky and the soil <br />thin, I will use the 0 - 8" thickness with a K Factor of .15. <br />Refer to Exhibit C1 Sediment Areas for area length slope and water flow direction. <br />• <br />
