ADEQUACY RESPONSE <br /> Exhibit A <br /> 1. Pursuant to Rule 6.4.1(1)(a) list the nearest quarter-quarter section. <br /> Exhibit A has been revised to list the nearest quarter-quarter sections that encompass the permit <br /> and affected area.Note that this is slightly different than the location of the center of the of the <br /> area of most mining from section nine of the application form. <br /> Exhibit C <br /> 2. Map C-2, Clarify the number of disturbed acres at each mining area that makes up the <br /> 41.4 total acres. The maps only shows the total permitted acreage by area 31.8 ac + <br /> 17.7 =49.5 ac. <br /> Each mining Areas disturbance area has been added to Map C-2. <br /> 3. A truck scale and scale house is mentioned on page D-3. Please depict the location of <br /> the scale and scale house on your map(s). <br /> A truck scale and scale house have been added to Map C-3. <br /> Exhibit D <br /> The Division discourages storing topsoil in piles taller than 4 feet high due to lack of soil <br /> aeration. Short long windrows is preferred over tall consolidated piles if at all possible. <br /> Additionally the Division would encourage you to consider storing topsoil in the backfilled <br /> portions of Area 2 until needed to reduce the need to bond for trucking soil. <br /> 4. What is the maximum length (LF) of vertical slope that will require cut and fill grading <br /> at any given time? This would be the perimeter mining walls of Area 1,plus the interior <br /> active mining high wall that will progressively be moved north. <br /> Please see the revised Exhibit D. <br /> S. Volumes necessary for backfilling Area 2 were not provided. What is the total backfill <br /> amount necessary?Also at any given time what is the maximum amount of material that <br /> will needed to backfilled Area 2 and where will that material be stored? <br /> Table E-2 has been revised due to show the topsoil and overburden requirements of each area. <br /> The maximum backfill required for Area 2 is shown in Table E-2 (Area 2 Material for <br /> Reclamation). Backfilling of Area 2 will take place concurrently with mining,therefore there is <br /> no point where 100%of the backfill volume will be required. Area 2 will require roughly <br /> 182,000 CY of backfill from Area 1 mining to complete reclamation. <br /> Area 1 overburden generation and Area 2 backfill requirements are limited to prevent either pit <br /> from getting"ahead"of the other.
