<br />~ -~ ~ DRAFT <br />The maintenance and reclamation plans for the roads at the Red Canyon No. 1 <br />and No. 2 mines are in conformance with the requirements of the regulations. <br />Maintenance will be conducted by an appropriate private sector contractor, <br />as necessary. The amended application states that backfilling will be completed <br />using tracked vehicles, excavators or backhoes, topsoiled and appropriately <br />revegetated. The road design, maintenance and reclamation aspects of the amended <br />permit application are judged by the Division to be in compliance with the <br />requirements of the regulations. <br />XXII. Sealing of Drilled Holes and Underground Openings (2. 05.4(2)(8), 4.07) <br />The applicant observes that exploration holes are cemented immediately following <br />drilling. Monitoring wells are properly cased, bottom-cemented and capped. <br />Further, the portals of both the Red Canyon No. 1 and No. 2 mines will be double <br />block wall sealed, in conformance with MSHR regulation 30 CFR 75.1711-2, and <br />then backfilled and graded, topsoiled and appropriately revegetated. The <br />Division finds these plans to be in compliance with the regulatory requirements. <br />XXIII. Subsidence (2.05.6(6), 4.20) <br />The amended permit application contains a complete inventory of potentially <br />effected structures and renewable resource Lands. Twelve structures are identified <br />on Table 2.05.6 (6)(a)(ii)(R)-1 and depicted on Land Use Map 2.04.3(2)(a)-1. <br />Further, the amended application delineates the alluvial aquifer of ward Creek, <br />which overlies the proposed underground workings, and constitutes a renewable <br />resource land. <br />The amended application also contains a thorough discussion of the worst possible <br />consequences which subsidence, if it occurred, could have for such structures <br />and renewable resource Lands. The applicant observes that structures would suffer <br />significant damage and that the alluvial aquifer of ward Creek might be dewatered <br />into the underlying underground workings. Volume VIII of the amended application <br />discusses the potential aquifer effects in detail and demonstrates that the <br />anticipated effects are projected to be insignificant and capable of remedy. <br />
