EXHIBIT D MINING PLAN 1. Introduction The following is the mining plan for the proposed Mystic Soil operation by permittee Colorado Gators Inc. It is anticipated that some material will be sold directly after being excavated, and some material will be mined and stored at the Mystic Soil site before being sold and transported offsite. There is sufficient topsoil and overburden onsite to successfully reclaim the site to its final condition of a recreational facility and industrial/commercial area. No material processing, asphalt or concrete manufacturing will take place onsite. 1.1 . Pre-Mining and Topsoil Stripping The site of the proposed Mystic Soil is currently rangeland/shrubland (see Map C-1). Prior to beginning activities on the site, the boundaries of the affected area will be clearly marked. Signs and markers will be posted at the mine entrance listing the name of the Operator, Colorado Gators Inc, and the operation name, `Mystic Soil'; a statement that a reclamation permit for the operation has been issued by the Colorado Mined Land Reclamation Board; and the DRMS permit number. Access to the site will be constructed in the southeast corner of the permit area (Map C-2). This access will remain following reclamation. internal access roads will be constructed along the northern and eastern parameters of the site. These temporary roads will be reclaimed at the end of mining activities. Map C-2 shows the full mining extents; Map C-3 shows cross-sections of the operation. Topsoil and overburden will be stripped at Mystic Soil and placed in stockpiles and berms. Mining of material at Mystic Soil is exclusively sand and soil for offsite sale. The final reclamation plan for each pit is use as a field covered with artificial turf and an industrial/commercial site. No soil will be salvaged from the pits. The stockpile area to the east of the pits will see its topsoil salvaged and stored in stockpiles for the purpose of reclamation of that area. No mining of product will occur in the topsoil stockpile area. Temporary stockpiles of overburden or topsoil required for reclamation will typically be less than 20 feet in height. Temporary stockpiles will be located in the designated area shown on Map C- 2. Because excavation will proceed to final slopes and grades of 3H:1V or shallower(Map C-3), it is anticipated that minimal backfilling with overburden will occur during reclamation. Overburden present on site will be stored in the stockpile area and sold as fill. Mining to final slopes will reduce the need to stockpile backfill material and shorten the time that it will take to reclaim the mine. Details on topsoil and overburden quantities and material balance can be found in Table D-2 and Table E-2. 1.2. Mining Phases Mining will take place in a single phase and will entail the excavating of four pits starting at the south end of the permit area and progressing north. Once topsoil is stripped from the site, the Mystic Soil November 2020 D-1 Lewicki&Associates
