• reclamation costs, EFCI, in compliance with applicable regulations, will increase or supplement the extsting bond [o reflect estimated incremental costs poor to initiating proposed changes. Removal of Structures and Faalities All existing mine structures and facilities will be utilized and remain in-place until mining operations for the Southfield Mine have been completed. At that time any structures facilities, and use azeas not approved for retention to support the postmining use will be salvaged or demolished in order to reclaim the site and establish proposed postmining land uses. It is antiapated that much of the equipment utilized at the mine including conveyor systems, rotary breaker, process equipment, storage hoppers, and [tuck scales, along with a number of pre-fabricated steel building can be salvaged for continuing benefiaal use at the end of the mine life. Any remaining equipment not salvaged will be dismantled, and any building or structures which will not be retained and cannot be salvaged will be demolished. Equipment and Facilities to be salvaged will be dismantled and hauled from the site by EFCI or private • salvage contractors. Disassembly and demolition of remaining equipment and structures will involve cutting steel structures and other large components into pieces which can be readily handled by mobile equipment breaking-up foundation slabs and masonry structures, and removing foundations and utilities to at least two (2) feet below the natural ground surface. Resulting demolition debris will be loaded and placed in appropriate disposal areas where it will be effectively covered by backfilling and grading operations with a tnirumum of four (4) feet of suitable material. All concrete will be broken up just enough so that it may be moved. All concrete debris will be disposed of in low azeas of the facility site, and boned. The low azeas include the azea in front of the portals (if portal structures aze not retained) and the Pond 1 basin azea. The concrete will be cazefully place so as not to create any voids which may cause slumping once backfilling is completed. All concrete debris will be covered with at least 4 feet of backfill material. Demolition debris from the south mine fan installation will be backfilled in the fan portal. • Minor Revision MR~1 2.05.47 Revised December 200]
