Drainage Reconstruction <br /> <br />Refer to Section 3.0 of this annual report. <br /> <br />Contour Ditch Construction <br /> <br />During 2020, Trapper did not construct any contour ditches. <br /> <br />Stock Tank Construction <br /> <br />No new Stock Tanks were constructed during the 2020 field season. Refer to Section 6. <br /> <br /> Stock Tank Reclamation <br /> <br />No Stock Tanks were reclaimed during the 2020 field season. Refer to Section 6. <br /> <br />Developmental Drill Sites <br /> <br />During the 2020 Developmental Drilling season 45 holes were drilled within the permit boundary <br />in the I, J, N and L pit areas. All applicable developmental drill holes were abandoned per <br />permit section 3.3.2 and will be reclaimed and seeded per section 3.6.3.5 of the permit. Drill <br />hole abandonment typically uses Alternative 2 for sealing of the borehole. <br /> <br />Topsoil Piles <br /> <br />During 2020, Trapper moved pile A92-2 to the new piles constructed near the ash dump road. <br />Trapper moved A97-3 to pile A94-2 and A98-2 was moved to the various new piles constructed <br />along the new LOM Road in the N-Pit area. Additional topsoil was also placed on pile 18-3. <br />Trapper constructed 16 new topsoil piles in the I, J, L and N Pit areas during stripping and re- <br />disturbance activities in the 2020 field season. Refer to Section 5. <br /> <br />Sediment Dams <br /> <br />No sediment ponds were cleaned or constructed in 2020. <br /> <br />1.2.6 Previously Revegetated Acres <br /> <br />The locations and acres for all previously revegetated areas, seeded to perennial species, are <br />presented in Map(s) 1. To date, Trapper has revegetated approximately 4,754.2 acres, <br />including 19.3 acres in 2020. Of the total revegetated acres, 3,597.2 reclaimed acres have <br />received final phase III bond release. The phase III total includes 178.7 acres of re-disturbance <br />in I and N-Pit during 2020. <br /> <br />Not shown on Map(s) 1 in this annual report are the areas seeded to temporary perennial mixes <br />that will require final reclamation prior to the end of the project (life of mine). <br /> <br />1.2.7 Re-Disturbed Reclamation Acres <br /> <br />The parcel identification and acres re-disturbed due to mining activities for all previously <br />revegetated areas will be documented here. Table 1.2 will show acres re-disturbed and <br />summarize the bond release status of each parcel. N Pit development resulted in 178.2 acres <br />of re-disturbance. I Pit development resulted in 4.7 acres of re-disturbance in 2020. <br /> <br />GCR 2/21 <br />[DRMS20RPT\20RECtext1-0]
