The inclusion of a staging area and access point will minimize soil compaction <br /> across the disturbance area. <br /> GRADING & RECONTOURING <br /> Final grading will support an appropriate seedbed for revegetation and for undetermined future land <br /> use.The substrate shall be contoured to emulate the surrounding land topography and facilitate future <br /> land development.In accordance with section 3.1.5(3)of the Rules,all grading shall be done in a <br /> manner to control erosion and siltation of the affected lands and to protect areas outside the affected <br /> land from slides and other damage.The anticipated post reclamation slope gradient for each of the four <br /> quadrants will not change from the present slope.Pursuant to Rule 6.4.5,refer to the Reclamation Plan <br /> Map for the anticipated final slope gradient. <br /> SEEDING & REVEGETATION <br /> Following mining activities,each quadrant will be revegetated to establish diverse,effective,and long- <br /> lasting vegetative cover(Rule 3.1.10(1)). The operator will mechanically cultivate the area by disk and <br /> plow to ensure the preparation of a proper seedbed and good seed to soil contact. As indicated in the <br /> Project Description,3-6 inches of topsoil will remain on Site after mining operations are complete to <br /> facilitate successful revegetation. If necessary,soil samples will be collected to identify nutrient <br /> deficiencies and determine if fertilizer applications or amendments are needed.Once prepared,the <br /> mined area will be seeded using a native grass seed mix. The site may also be mulched to stabilize <br /> revegetation efforts. Planting native grasses reduces the need for long-term irrigation,soil <br /> amendments,and weed maintenance. <br /> Sanay Site ',1i eud Mix for Welch County', <br /> Seed Species Variety Seeding Rate* Planting Depth <br /> Sand Bluestem Champ,Chet 1.00 Ibs pls/acre <1/2 inch <br /> Sand Lovegrass Bend,Native,Ne27 2.50 lbs pls/acre <1/2 inch <br /> Indian Ricegrass Nezpar,Rimrock 3.00 Ibs pls/acre <1/2 inch <br /> Prairie Sandreed Goshen 0.75 Ibs pls/acre <1/2 inch <br /> Green Needlegrass Lodorm 1.50 Ibs pls/acre <1/2 inch <br /> Little Bluestem Blaze,Cimarron, 0.75 Ibs pls/acre <1/2 inch <br /> Camper <br /> Yellow Indiangrass Cheyenne,Holt,Scout 0.50 Ibs pls/acre <1/2 inch <br /> Switchgrass Blackwell,Nebraska 28 1.50 Ibs pls/acre <1/2 inch <br /> Sand Dropseed ---- 0.50 Ibs pls/acre <1/2 inch <br /> 12.00lbs pis/acre <br /> kscr uin�t ndatcc n�zr., i :-ed on drill seeding;apphcatcun <br /> To ensure the greatest possibility of plant establishment,an approved,local seed mix developed by <br /> Weld County has been selected z The species in this seed mix have been selected based on their success <br /> given the seasonal patterns of precipitation,temperature and wind,soil texture,and fertility.Seeding <br /> rates and time of planting has been recommended by Weld County officials,and the Weld County <br /> Conservation District.
