• reclamation measures and material handling including permissible slopes, <br />hazardous materials — none, backfilling — none, releases of pollutants to <br />groundwater - none (3.1.5); <br />(d) Topsoil Segregation, Preservation, and Replacement: Because the mining operation is <br />intended only to remove excess topsoil and a sufficient layer of topsoil (2' to 3') shall be left in <br />all areas affected, there will be no need to segregate, preserve, or replace topsoil needed for <br />revegetation (replanting). For re- seeding species and planting schedule see below. <br />(e) Reclamation Schedule: <br />(i) Timing of Reclamation Stages: Re- grading of slopes to shallower than 3:1/H:V will <br />occur periodically as each mining unit is operated. Revegetation will be accomplished in <br />either the Spring or Fall following after cessation of operations within a unit after <br />resource exhaustion, according to dry -land or crop -land species requirements. In no case <br />will more than two mining units be either under operation or reclamation activities at any <br />given time. <br />(ii) Size and Location Reclamation Areas: Mining units are all less than 10 acres in size. <br />The location of slopes and revegetation are shown on the Reclamation Map (Section <br />6.4.6 Exhibit F). <br />(iii) Reclamation Sequence: See previous discussion and Reclamation Map..) <br />(f) A description of each of the following: <br />(i) Final Grading: Slopes shall be no steeper than 3:1/H:V. <br />(ii) Seeding: Dry -land (early Fall planting) - Certified Weed -Free Russian Wild Rye <br />(12 -15 lbs. per acre) and Certified Weed -Free Western Wheat Grass or Intermediate <br />Wheat Grass (5 -10 pounds per acre). It should be noted that the owner's four - generation <br />farming experience in this region indicates that ever - present Kochia weed will inevitably <br />inhabit un- irrigated disturbed land. Crop (Post -frost Spring planting) - Certified Weed - <br />Free Meadow Brome (15 -18 pounds per acre), Certified Weed -Free Alfalfa (10 -12 <br />pounds per acre) and Certified Weed -Free Oats (20 -50 pounds per acre). <br />(iii) Fertilization: None. <br />(iv) Revegetation Trees and Shrubs: None. <br />(v) Topsoiling: None required as sufficient topsoil will remain in place in all areas. <br />6.4.6 EXHIBIT F - Reclamation Plan Map <br />See attached large format Reclamation Plan drawing. <br />8 <br />
