and reclamation activities in the area of the mine during the current permit term. <br />This CHIS is available under separate cover in the files of the Division. <br />Pursuant to Rule 2.07.6(2)(c) and in consideration of the absence of <br />demonstrated significant hydrologic impacts by anticipated mining and <br />reclamation operations in the study area, either individually or cumulatively, the <br />Division finds the proposed Southfield Mine operation to have been designed to <br />prevent material damage to the hydrologic balance outside the proposed permit <br />area. <br />IV. Topsoil <br />Topsoil resource information is contained in Section 2.04.9 of the permit <br />application. Topsoil handling information is in Sections 4.06 "Topsoil", 2.05.3 <br />"Operations Plan" and 2.05.4 "Reclamation Plan". The location of the five topsoil <br />piles that were at the mine site can be seen on Map No. 14, "Mine Soils Map". <br />There were four topsoil piles at the mine site that consisted of topsoil salvaged <br />during initial construction of the refuse area and one topsoil pile at the Newlin <br />Creek Mine. There was no topsoil salvaged for the facility area since it had been <br />disturbed from previous pre-law mining operations. There are no proposed <br />operations that will require further topsoil stripping. <br />Topsoil stripping depths at the refuse pile were 4 feet. The operator salvaged <br />approximately one foot of "A" horizon and three feet of "B" horizon material from <br />this area. Soil analysis indicated little difference between the two soil horizons, <br />as plant growth media. The Division previously determined that there was no <br />need to store the A and B horizon materials separately. The operator was only <br />required to handle these materials separately when "live handled". Live handled <br />topsoil was reapplied immediately after stripping. <br />With the submission and approval of Technical Revision 20, the Division finds <br />that there is adequate topsoil to complete the approved reclamation plan. This <br />Technical Revision resulted in the termination of Stipulation 24. <br />V. Sealing of Drilled Holes and Underground Openings <br />Drill holes from 1987 and 1988 exploration projects within the permit area have <br />been filled and sealed, as described in the "Proposed Decision, Phase I Bond <br />Release" Document dated September 15, 1990. <br />Detail of the five portal sealing plans can be found in Sections 4.07.3 and 2.05.4, <br />page 8 R of the permit application. The mine portals have been sealed by <br />constructing a concrete block wall as depicted on Figure 21, seen on page <br />2.05.4-9. MSHA approved techniques and sealant were applied to all five portal <br />seals. Once the seals were in place, the entry between the seal and opening <br />Page 28 of 36
