Pit Benches <br /> The pit benches, being roughly level, can be revegetated. Overburden will be placed on the pit benches, <br /> at a depth of approximately one foot (12 inches). Topsoil will be placed at a depth of at least 6 inches on <br /> top of the overburden on the benches. Broadcast seeding and dragging will follow topsoiling. <br /> The entire site will be monitored for erosion and sedimentation, especially on disturbed areas being <br /> reclaimed. Any problem areas will be addressed in a timely manner. <br /> Revep,etation <br /> Revegetation seeding will be carried out on all disturbed surfaces,with the exception of some roadways <br /> and exposed obsidian in the quarry pit. Mulch will be spread after seeding, and fertilizer will be applied <br /> as needed after seed germination. <br /> Seed Mix: Seed Name Variety Pounds of PLS/Ac <br /> Western wheatgrass Arriba 9.6 <br /> Arizona fescue Redondo 0.9 <br /> Little bluestem Pastura 1.4 <br /> Total pounds PLS/Ac 11.9 <br /> The seeding rates above are for drill seeding; the rates should be doubled for broadcast seeding. Drill <br /> seeding will be done on a seedbed that was prepared by ripping all deep compaction and lightly tilling <br /> the surface topsoil layer. Drilling will place the seed %to% inch deep. If broadcast seeding is used, light <br /> raking or dragging will follow broadcasting to incorporate the seed in the soil. <br /> Mulch will be spread over seeded areas at the rate of 1000 to 2000 pounds/acre (dry weight). Straw is <br /> recommended since it will not attract grazing animals prior to seed germination and establishment. It <br /> will be crimped to keep it in place. <br /> Fertilizer will be applied, as needed, after seed germination so it will be available to seeded species and <br /> not to weeds. Application rates should be 40 pounds actual nitrogen and 40 pounds actual phosphate <br /> per acre. <br /> Areas which fail to become revegetated will be addressed by reseeding and/or other practices <br /> considered to be necessary. <br /> Noxious weeds will be monitored and controlled during reclamation, by following the same weed control <br /> plan currently in place for the permit. <br /> Structures and Equipment <br /> All mining-related buildings, tanks, and equipment will be removed from the permit area. The disturbed <br /> footprint of these features will be reclaimed (as needed by ripping, topsoiling, seeding). <br /> Earthen stormwater control structures (berms, dips, culverts, etc.)will remain as permanent features. <br /> Conclusion of Mining <br /> At the conclusion of the operations, all areas and features of the site will be fully reclaimed. This means <br /> the quarry will have stable, benched highwalls; slopes will be topsoiled and revegetated (excluding in- <br /> quarry surfaces with exposed obsidian); earthen stormwater controls will remain as permanent <br />
