M MW Sorter <br /> V <br /> DRMS(Item#17): As required by Rule 6.3.4(1)(e), please provide details and designs on the backfilling of <br /> barren waste rock to ensure a stable configuration of the replaced material. <br /> MW Sorter(Item#17 Response): Exhibit D was updated with the following: <br /> Backfill will be placed and smoothed in stable lifts with the slope comprised of inert sorted product <br /> material, placed by loader or compacted dozer lifts. The surface will be sloped at 2H:1V as shown in <br /> Exhibit E Reclamation Plan. <br /> DRMS(Item#IS): As discussed above, the Operation will now salvage the native material underneath the <br /> South London Stockpile Area to be used as a growth media for reclamation prior to seeding the site for the <br /> purposes of stabilization and the protection of off-site lands. Please update Exhibit D with this revised plan <br /> and provide details to address the measures that will be taken to revegetate the site as required by Rule <br /> 6.3.4(1)(c). <br /> MW Sorter(Item#18 Response): Exhibit D was updated with the following: <br /> As native material is exposed, fine grained soil-like material will be excavated and stockpiled on the <br /> upgradient side of the area. Once material is excavated and stockpiled, soil tests will be conducted by a <br /> third-party laboratory to determine soil quality and what amendments if any are needed. <br /> DRMS(Item#19): The quality of growth media underneath the South London Stockpile Area is unknown <br /> and could be degraded. Please demonstrate through a soil test that the material planned to be salvaged <br /> as growth media is of sufficient quantity and quality to cover and revegetate the backfilled barren waste <br /> rock and the footprint of the removed historic waste rock stockpile. If the soil tests indicate soil <br /> amendments are needed, please provide the specific recommendations for how the soil needs to be <br /> modified to support revegetation. Otherwise the Applicant may propose a plan to import the necessary <br /> growth media to the site. Please revise Exhibit D and Exhibit U to address these comments in accordance <br /> with Rules 6.3.4(1)(c)(i)and(ii)and Rule 6.4.21(17). <br /> MW Sorter(Item#19 Response): Exhibit D was updated with the following: <br /> If native soil horizon beneath the South London Stockpile area is impaired, it will be due to depletion of <br /> organic matter content and nutrients from being covered for many decades. Applicant will amend the <br /> fine-grained material with necessary compost and fertilizers as needed to provide support for <br /> revegetation of the final cover. <br /> DRMS(Item#20): Please provide the size of the disturbance footprint associated with each of the waste <br /> rock stockpiles. <br /> MW Sorter (Item#20 Response): South London Stockpile is 4.3 acres, and the Central Extension Area <br /> Stockpile is 1.3 acres. These estimated areas were added to Exhibit D. <br /> DRMS (Item #21): The Division will calculate the total required financial warranty for the site after the <br /> responses to this review letter are received. The Division will provide the Applicant a copy of the Division's <br /> reclamation cost estimate for review prior to the decision on the application. <br /> No response needed. <br /> 8 1 P a g e <br />
