Topsoil Handling, Stockpiling and Redistribution <br />1.0 Introduction <br />All predicted topsoil salvage information is located in permit Section 2.04.9 Soils Resource <br />Information. As of the submittal of PR -08, all topsoil from the site has been stripped. Much of <br />the topsoil stripped from areas west of 2700 Road has been placed in various stockpiles. Actual <br />topsoil salvaged has been measured in all the stockpiles and a full volume balance has been made <br />for the proposed redistribution of soil. The topsoil handling and stockpiling requirements of Rule <br />2.05.3(5) are addressed in this permit Section 2.05.4(2)(d). All topsoil replacement information <br />is also in this permit Section. Prime farmland specifics (Rule 4.25 satisfaction) of topsoil <br />handling are found in permit Section 2.06.6. <br />Completion of reclamation activities at the New Horizon Mine will depend in large part on <br />finalization of a long-term water treatment plan for the Trench Drain discharge. Some of the <br />options being considered could result in the need to construct treatment facilities within the final <br />backfilling, grading and topsoil redistribution areas. Therefore, an extension to the 180 day <br />requirement for completion of rough backfilling and grading, as outlined in Rule 4.14.1(1)(c), is <br />necessary until a long-term treatment plan has been finalized. <br />This section outlines New Horizon's plan for removal, storage and redistribution of topsoil, <br />subsoils and other material, to meet the requirement of Rule 4.06. The plan addresses <br />reclamation activities that are conducted during and immediately after backfilling and grading <br />(Section 2.05.4(2)(c)), but prior to revegetation (Section 2.05.4(2)(e)). The objectives of the plan <br />are to reconstruct plant growth and aquifer mediums that are capable of supporting the post <br />mining land uses. The plan presents an account of the plant growth material and aquifer medium <br />requirements based upon current and projected disturbance acreage and plant growth material <br />and aquifer medium availability based on topsoil depth mapping and overburden assessments. <br />The plan also describes the procedural aspects of removal, storage, redistribution, and testing of <br />topsoil materials. <br />As of the submittal of PR -08, all mining areas east of 2700 Road have been backfilled, topsoiled <br />and seeded according to the requirements of the approved permit. Large portions of this area <br />have been granted Phase 1 and Phase 2 bond release. The majority of this area has been restored <br />to Irrigated Pasture with excellent productivity. Topsoil erosion has been extremely low due to <br />the vegetation present. No topsoil redistribution for the areas east of 2700 Road have been <br />affected by the changes present in PR -08. <br />July 2018 (TR -84) 2.05.4(2)(d)-1 <br />
