The soil erodibility factor, "k- Factor ", values are based on Seneca II soil survey information (see Tab 9, Exhibit 9 -1, Soil
Type and Sampling Locations, and Attachment 9 -6 of the Seneca II Mine PAP) as presented in Soils of Colorado, Loss
Factors and Erodibility, Soil Conservation Service, 1983.
The Control Factor values are adapted from Seneca Coal Company mine permit application packages. They are
representative of regional conditions and previously approved by CDRMS in the Seneca II Mine PAP, Permit C -80 -003.
The values are adapted from Renard, et al. (Renard, K.G., Foster, G.R., Weesies, G.A., McCool, D.K., and D.C. Yoder,
coordinators, 1996. Predicting Soil Erosion by Water: A Guide to Converation Planning with the Revised Universal Soil
Loss Equation (RUSLE) . Agricultural Handbook 703. U.S. Department of Agriculture.
