Bob Oswald <br />Re: Camation Mine, Permit M-1977-416 <br />Request for Technical Revision <br />Page 2 of 4 <br />these two Permits sharing a common boundary. Reclamation of the Camation and Sunday sites <br />will be facilitated by incorporating this suggested revision. <br />The requested boundary revision will incorporate the entire waste dump located in the southwest <br />comer of the Permit; previously, a portion of this dump was outside the Permit boundary. <br />An updated mine site map, "CARNATION MINE, PERMIT M-1977-416, 1" = 100,' is <br />enclosed. This map shows the revised Permit boundary. This boundary was marked in the field <br />during early November 2003, and the Operator has provided formal notification to the Division <br />of Minerals and Geology of the marking of the boundary. <br />Reclamation Plan <br />The Camation Mine was originally permitted by Pioneer Uravan, Inc. in 1978. The Camation <br />Mine was subsequently acquired by Union Carbide, which also held permits for a number of <br />other mines in the Camation Mine vicinity. As a consequence of the evolution of operators, <br />reclamation plans for the five permits now held by this current Operator for mines in the area are <br />not consistent. This Operator prefers to take this opportunity of submitting a proposal for a <br />Technical Revision to make minor clarifications and revisions to the reclamation provisions in <br />the Permit so that reclamation practices will be uniform (subject to individual site conditions and <br />requirements) for the five permits held by this Operator in the Carnation Mine area. These <br />changes will facilitate reclamation planning and execution. <br />Portal Closure: As noted in the Permit, the Carnation Mine portal will be permanently <br />closed by pulling the structural support in the portal entrance and backfilling with barren rock. <br />The portal entrance structure and gate will be removed prior to final plugging of the portal. The <br />decline is approximately 10' x 10' in section. The Operator proposes that, prior to closing the <br />portal, site debris and trash be placed in the portal for permanent burial. This will include <br />placing debris from buildings and concrete floor slabs in the portal, which will provide a solid <br />stop against which backfill material will be placed. <br />Filling and reclamation of the portal will be conducted with a small capacity front-end loader <br />(likely in the 3 cu. yd. range). In addition, a small track mounted dozer, or equivalent, will be <br />used to push fill material up in the portal to ensure that it remains stable. <br />As with all disturbed areas occumng on sloping ground, the final graded exterior surface of the <br />portal plug will not exceed 2:1 slope. <br />Building Debris and Slabs: The external dimensions of the Camation Mine <br />shop/dry/office metal building are 32' x 28'. This building has a "T" shape with insets of 5' x <br />16' and 8' x 16'. Another metal building is located at the northern end of the Permit. This <br />building is 32' x 24', and there is a 14' x 16' concrete slab immediately to the north of this <br />building. Both buildings and the concrete slabs will be removed in final reclamation. <br />Concrete slabs are generally 4 inches thick, although there may be areas of slightly thicker <br />concrete due to irregularities in the substrate during placement of concrete. Concrete slabs are <br />typically reinforced with-wire mesh, and occasionally minor amounts of trash steel were placed <br />in the pours for additional strength. <br />
