• EFCI plans to utilize direct replacement, or live topsoil handling where <br />practical. Live handled topsoil will be transported from topsoil recovery <br />areas and replaced directly on regraded disturbance areas. This approach <br />preserves beneficial biological and chemical properties of the soil and <br />takes advantage of plant propagules recovered with the soil during removal <br />as a primary or supplemental source for vegetative reestablishment. <br />In order to promote effective vegetative reestablishment, EFCI will sample <br />and complete laboratory analyses on the upper four (4) feet of replaced <br />soil and other surficial materials prior to seeding. Objectives of <br />sampling will be to determine suitability of the upper four (4) feet of <br />material for use as a vegetative growth medium and to identify any <br />deficiencies in critical soil nutrients. Representative soil samples will <br />be taken on 500 foot centers to obtain a bulk soil sample. Total sampling <br />depth will be four (4) feet with each one (I) foot sample collected and <br />bagged separately. As soon as samples are collected they will be placed <br />in clean plastic sample bags, sealed, and labeled. Soil samples will be <br />• analyzed for the same parameters utilized during the baseline soil <br />sampling as listed by Table 23, Soil Analysis Parameters in Section <br />2.04.9, Soils Resource Information. If any of the samples indicate <br />potential suitability problems, the area/increment (s) of concern will be <br />identified and the area/increment will be re-sampled. If the backup <br />sample also indicates potential suitability problems, EFCI will have the <br />option of delineating potentially unsuitable materials, removing these <br />materials and replacing them with suitable materials, or capping the <br />materials with an adequate thickness of suitable material. If soil <br />analysis results indicate deficiencies of critical soil nutrients, EFCI <br />will design and implement a soil conditioning program in cooperation with <br />and based upon the recommendations of Colorado State University- <br />Cooperative Extension Service. <br />Reveaetation Plan <br />All existing and future disturbance within the Southfield mine and loadout <br />• areas will be reclaimed to post-mining land uses of rangeland and wildlife <br />habitat consistent with pre-mining land use patterns. Backfilling and <br />grading will address re-establishment of a topographic configuration <br />2.05.4-17 <br />
