i After mining has passed through an area, non-marketable material and overburden will be replaced at an even depth of 6 to 12 inches along shorelines and graded. Soil amendments are not proposed due to the organic nature of this topsoil. However, if they are determined necessary by the SCS they will be used to enhance plant growth. Revegetation The reclamation plan will revegetate all disturbed areas with appropriate seed mixes to minimize erosion, re-establish natural terrain and create usable farm land. Reseeding of the property will be done after topsoil is replaced in accordance with accepted planting practices. All grass seeds will be planted with a grass drill equipped with depth bands and press wheels. Seed will be planted approximately one-half inch deep and will be drilled between November 1 and April 1 . The grass seed mix includes drought resistant varieties and will be planted either in early spring or fall to insure germination. I Grasses planted in early spring should be warm season cover crops. The permanent grass seed should then be drilled into the cover crop in early fall without additional tillage. Grasses planted in the early fall should be permanent grasses and covered with straw mulch at a rate of 4000 lbs. per acre immediately following seeding. The straw should then be crimped into the soil to control erosion until the grass becomes established. Seed rate mixes and ratios are listed on the table immediately following this discussion. This information was provided by the SCS. If a significant invasion of noxious weeds occurs, the area will be mowed periodically for control. Weeds will be mowed when they reach a height of 6 to 12 inches throughout the first growing season. Mechanical control will be used as a first priority. Chemical methods will only be used if no other alternative produces acceptable results. The property is not forested and will not require fire lanes. A minimum 30 foot setback will be maintained around the permit boundary which will allow access. The reclamation of all processing sites will be delayed until the final phase of mining is completed. At that time the ground will be scarified, leveled, and seeded with grass. g-3
