The seeding rates above are for drill seeding;the rates should be doubled for broadcast seeding. Drill seeding will be done on a seedbed that was prepared by ripping all deep compaction and lightly tilling the surface topsoil layer. Drilling will place the seed %to%2 inch deep,with light compaction. Drill seeding will be carried out on pad and stockpile areas, pit floor and some roadways. Broadcast seeding will be carried out on areas less accessible to equipment,such as the pit benches. Where it is carried out, light dragging will follow broadcasting to incorporate the seed in the soil. Mulch will be spread over seeded areas at the rate of 1000 to 2000 pounds/acre (dry weight). Straw is recommended since it will not attract grazing animals prior to seed germination and establishment. It will be crimped to keep it in place. Again, wherever possible, large equipment will be used for mulching, and smaller equipment will be used in less accessible areas. See Exhibit L for acreages. Fertilizer will be applied,as needed, after seed germination so it will be available to seeded species and not to opportunistic weeds. Application rates should be 40 pounds actual nitrogen and 40 pounds actual phosphate per acre. It can be applied by a spreader mounted on ATV. Areas which fail to become revegetated will be addressed by reseeding and/or other practices considered to be necessary. Noxious weeds will be monitored and controlled during reclamation, by following the weed control plan for the permit. This application packet includes updated information regarding the weed control plan. Structures and Equipment All mining-related buildings,tanks,and equipment will be removed from the permit area. The disturbed footprint of these features will be reclaimed as needed by ripping,topsoiling,seeding. Earthen stormwater control structures(berms,dips,culverts, etc.)will remain as permanent features. Conclusion of Reclamation At the conclusion of the reclamation operations, most areas and features of the site will be fully reclaimed (some roads being the exception, as stated below). This means the quarry will have stable highwalls and revegetated benches; slopes will be topsoiled and revegetated (excluding quarry wall surfaces with exposed obsidian); earthen stormwater controls will remain as permanent structures; roadways will be either stabilized to remain as permanent, or reclaimed by ripping followed by topsoiling and seeding; all required topsoil will be spread and seeded; all product stockpiles will be removed; all disturbed areas will be topsoiled and seeded; all equipment, debris and supplies will be removed; and the operations pad area will be ripped,topsoiled and seeded (including the drainage channel to be constructed there). Reclamation Timeframes Year 1 (mining stage) Concurrent reclamation:grading and seeding of topsoil and overburden stockpile areas;grading,topsoiling and seeding of overburden slopes above quarry highwall; earthen berms constructed and seeded. Year 2-20 (mining stage) Mining activities carried out in the described pit segments,with limited concurrent reclamation carried out where possible in those mining segments, and in mining activity areas. Activities will include moving overburden and topsoil,stockpile stabilization,seeding or reseeding,etc.
