2. Reclamation Timetable <br /> Reclamation will take place concurrently with mining with an additional estimated 6 months of <br /> reclamation commencing after mining is completed. Mining is projected to be completed by <br /> 2065. Therefore, final reclamation and bond release is expected to be completed by 2066 or <br /> within 46 years. Exhibit L: Reclamation Costs describes the worst-case bond scenario. <br /> 3. Revegetation Plan <br /> For each area of reclamation, soil will be disked to loosen surficial soils. Due to the mild grade, <br /> seed can be drilled in most areas, but broadcast seeding will be utilized where reclaimed <br /> perimeter slopes do not allow drilling. The seed mix listed below(Table 3.1)will be used to <br /> revegetate the site with a native grass mix on all surfaces. This seed mix was verified as adequate <br /> for the Bradford Mesa area by Anthony Arnhold of the NRCS Colorado Area 2 Office which <br /> includes Walsenburg, Colorado on December 17, 2019. <br /> Certified weed free mulch will be crimped into the surface at 4000 lbs. per acre, i.e. 2 tons of <br /> weed free mulch per acre. Fertilizer may be added as determined by a soil test at the time of <br /> seeding. Surface roughening will be used in tilled topsoil to provide moisture concentration and <br /> shade areas in order to promote better conditions for successful vegetation establishment. <br /> Surface roughening is detailed in the attached Surface Roughening section from the Urban Storm <br /> Drainage Criteria Manual Volume 3 (November 2010) included at the end of this exhibit. In <br /> areas where slopes or material conditions do not permit for drill seeding, broadcast seeding will <br /> occur at double the drill seeding rate. See the Temporary and Permanent Seeding section from <br /> the Urban Storm Drainage Criteria Manual Volume 3 (July 2012) included at the end of this <br /> exhibit. Seeding will take place during the fall following retopsoiling of slopes. Slopes will be <br /> regraded, backfilled, and retopsoiled as soon as they are able to be reclaimed and as additional <br /> mining phases become active. <br /> Bradford Mesa Quarry I:n i wicW and\s.ocute�Pl t.t <br /> January 2020 E-9 <br />
