Sedgwick County Road and Bridge Gravel Pit Page 10 <br /> 112(c) Operation Reclamation Permit February 25, 2024 <br /> Seeding of topsoil will be done as soon as feasible after topsoil has been placed, ideally not more <br /> than 2 days after placement to prevent loss of topsoil quality and invasion of undesirable plant <br /> species. <br /> The reclaimed area will be monitored for three years with general observation from operators that <br /> good revegetation is taking place.Areas where no vegetation has grown or where there is invasion <br /> from noxious weeds shall be recorded. This will ensure that proper vegetation occurs within five <br /> years of ceased mining operations. Observations will be recorded 4 times a year for 3 years after <br /> seeding. <br /> If acceptable revegetation to control erosion is not taking place the ground in the area of poor <br /> vegetation will be revegetated according to this plan and the area will be monitored for three <br /> additional years. Additionally, if noxious weed invasion threatens the continued development of <br /> the desired vegetation it will be removed and the area that had noxious weeds will be revegetated <br /> according to this plan and the area will be monitored for one additional year. <br /> 5.5 Seeding <br /> The NRCS has provided recommendations for reclamation. This includes seed bed preparation, <br /> method of seeding,and seed mix to be planted.They are described below.These recommendations <br /> are shown in Appendix B and Table 2 below. <br /> 5.5.1 Seedbed Preparation <br /> A no till seedbed preparation is recommended, topsoil will be placed in one 6-12 inch lift and <br /> compaction of topsoil shall be avoided as much as feasible. <br /> 5.5.2 Seeding Method <br /> Seeding will be done with a no-till seed drill applicator. <br /> The NRCS did not provide specifications on drill seeding. To ensure good revegetation, the same <br /> drill seeding method will be used that is in an approved permit for the Colorado Land Board pit in <br /> Washington County.
