The following values for the remaining factors have been approved in previous submittals: <br />Rainfall Factor R = 30 <br />Soil Erodibility Factor K = 0.32 J <br />Erosion Control Practice Factor P = 1.0 <br />The ECCS weighted values, and USLE parameters/values for each demonstration area in <br />comparison to the undisturbed area follows the summary page for each demonstration <br />area. <br />Conservative values were utilized throughout the USLE calculations for each of the areas. <br />Jr~ ~ <br />Discharge from Ponds M3N and M3S (which currently receive approximately 60% of the ~~r \5~,< <br />disturbed area drainage) have met applicable effluent standards for quite some time. c'~ /Q <br />Given the fairly homogeneous nature of the reclaimed areas, the demonstration areas N~ <br />should also meet the effluent standards. <br />• Evidence of excessive siltation or soil movement is lacking in all three demonstration <br />areas, with such observations being supported by the ECCS value for each area. Water <br />samples collected from Middle Creek (above and below the drainage point for <br />Demonstration Area #2) showed no significant differences under either dry conditions or <br />immediately following a rainfall event. These factors (coupled with the historic values for <br />the M3N and M3S discharge) support the submission of these areas under Rule 4.05.2121. <br />r1 <br />TR 90-06 Exhibit 3 - 43 Revised 11/16/90 <br />
