Following removal of the <br />casing, the wells will be filled with cement and other acceptable <br />plugging materials from the bottom of the hole to the surface per <br />Exhibit D.3.3, Well Abandonment. <br />At the completion of commercial mining operations, all surface <br />facilities will be dismantled. Areas previously occupied by <br />these facilities, and any remaining areas associated with the <br />well field, will be reclaimed and revegetated according to <br />procedures describe~9 in this Section. <br />Surface facilities include the process plant building, product <br />• storage and load-out facility, roads, parking lots, pipelines, <br />power lines, retention ponds, and the evaporation pond. These <br />facilities will be dismantled, and either salvaged or removed for <br />disposal. Concrete foundations and road pavement will be broken <br />up and buried on-site at least three feet below final grade. <br />Salts remaining in the evaporation pond will be removed from the <br />pond and disposed of either in a mined-out cavity or at an <br />approved off-site disposal location. The evaporation pond liner <br />will be removed and disposed of at an approved off-site landfill. <br />The natural gas and water pipelines will be disconnected and <br />purged; they will be left in place because these areas will have <br />already been reclaimed and revegetated. <br />• <br />
