• EFCI plans to utilize direct replacement, or live topsoil handling where practical. Live handled topsoil will be transported from topsoil recovery area and replaced directly on regraded disturbance areas. This approach preserves beneficial biological and chemical properties of the soil and takes advantage of plant propagules recovered with the soil during removal as a primary of supplemental source for vegetative reestablishment. In order to promote effective vegetative reestablishment, EFCI will sample and complete laboratory analyses on the upper one (1) foot of replaced soil and other su~cial materials prior to seeding. Objectives of sampling will be to identify any deficiencies in critical soil nutrients and any potential salinity problems that could limit vegetative reestablishment. Representative soil samples will be taken on 500-foot centers to obtain a bulk soil sample. Total sampling depth will be one (1) foot with each sample collected and bagged separately. As soon as samples are collected they will be placed in clean plastic sample bags, sealed, and labeled. Soil samples will be analyzed for pH, texture, nitrate nitrogen, phosphorus, potassium, calcium, magnesium, and sodium and SAR values will be calculated. If soil analysis results indicate deficiencies of critical soil nutrients, EFCI will design and implement a soil conditioning program in cooperation with and based upon the recommendations of Colorado State University -Cooperative Extensive Service. The CDMG will be notified of any salinity concerns identified. Revegetation Plan All existing and future disturbance within the Southfield mine and loadout areas will be reclaimed to post-mining land uses of rangeland and wildlife habitat consistent with pre- mining land use patterns. Backfilling and grading will address reestablishment of a topographic configuration TR-34 2.05.4-17 Revised 8/02
