Windsor East Mine, Exhibit E – Reclamation Plan September 2022 <br /> Page 3 | 4 <br /> <br />Services (SCS) will be contacted periodically throughout reclamation for soil tests. SCS soil fertilizer <br />recommendations, if any, will be followed. <br />7.0 REVEGETATION <br />Following topsoil replacement, reseeding will be performed according to SCS recommended practices. Based on <br />SCS guidance for other local projects having similar surficial soils, the following revegetation procedures are <br />anticipated <br /> Grass seed will typically be planted in unfrozen soil between October 1 and April 30. <br /> Grass seed will be planted with a grass drill, or where necessary, with a broadcast seeder. <br /> The proposed seed mix and application rates in pounds of pure live seed per acre are described on the <br />following pages. <br /> Weed control practices will be implemented as required. <br />The above procedures may be modified as conditions dictate. If a significant invasion of noxious weeds occurs, <br />the area will be mowed periodically for control. Weeds will be mowed before they go to seed during the first growing <br />season. Mechanical control will be used as a first priority. Chemical methods will be used only if no other alternative <br />produces acceptable results. <br />8.0 WEED MANAGEMENT PLAN <br />A weed management program will be undertaken to control noxious and invasive plant species and to replace those <br />species with native and naturalized vegetation. Canada thistle (Cirsium arvense) and leafy spurge (Euphorbia <br />esula) will be treated by a combination of mowing at regular intervals and herbicides used at the appropriate times <br />and applications levels. Please see the attached Weed Management Plan. <br />9.0 SEED MIX FOR UPLAND AREAS <br />Notes: <br />Common Name Scientific Name Variety % of <br />Mix <br />PLS <br />Application <br />Rate (lbs/ac) <br />Western Wheatgrass Agropyron smithii Arriba 17.0% 1.74 <br />Sideoats Grama Bouteloua curtipendia Butte 17.5% 1.80 <br />Mountain Brome Bromus marginatus Bromar 17.0 % 1.74 <br />Prairie Sandreed Calamovilfa longifolia Goshen 1.0% 0.48 <br />Switchgrass Panicum virgatum Pathfinder 7.0% 0.67 <br />Alkali Sacaton Sporobolus airoides 1.0% 0.10 <br />Needle and Thread Stipa comata 13.0% 1.29 <br />Northern Sweetvetch Hedysarum boreale Timp. 10.0% 1.02 <br />Rocky Mountain Penstemon Penstemon strictus Bandera 5.0% 0.46 <br />Scarlet Globemallow Sphaeralcea coccinea ARS2936 3.0% 0.26 <br />Prairie Wildrose Rosa Arkansana 8.5% 0.87 <br />Total lbs/ac 100% 10.43
