disturbed area were primarily Pinion-Juniper woodland or dry shrub community. Both <br />had very little herbaceous growth. The reclaimed vegetative community will be <br />perennial grass community with some forbs and shrubs in low percentages. <br />The Revised Universal Soil Equation (RUBLE) as seen below can describe the soil loss <br />for defined area. <br />A=RxKx(LxS)xCxP <br />Where: <br />A =Soil loss in tons/year per acre <br />R =Rainfall Factor <br />K =Soil Erodibility Factor, <br />L x S =Length Slope Factor, <br />C =Cover Factor, and <br />P =Erosion Control Factor <br />Because very little material was actually mined and site terrain remains the same as prior <br />to mining the variables to determine erosion are greatly reduced. The purpose of this <br />requirement is to show that: <br />A Rulaimed ~ A Premine• <br />This is expressed can be proved by the following: <br />R Reclaimed X K Reclaimed X (L X S) Reclaimed X C Reclaimed X P Reclaimed ~ <br />R Premine X K premine X (L Premine X S Preminel x C Premine X P Premine <br />R Reclaimed = R Premine because the site location has not changed therefore the <br />Rainfall factor has not changed <br />K Reclaimed = K Premine because the site's soil was salvaged and replaced <br />L x S Reclaimed - L x S Premine because the site's topography has not changed <br />P Reclaimed = P Premine because the both the premine and reclaimed site have <br />special erosion control structures <br />The following must be proved; <br />C Reclaimed ~ C Premine <br />This is easily proved first by the fact that site has passed its vegetative cover requirement, <br />and secondly by the difference in vegetation community. The premining community was <br />a shrub-based community. While reclamation community is a grass community. <br />
