Please provide the disturbance acreage on the re-submitted map(s). If there are roads that are not to be <br /> reclaimed, please provide rationale for why they do not need to be reclaimed. <br /> Response: Exhibits C-1 and C-2 have been revised to include the topsoil stockpiles and roads in the <br /> "Disturbance Area".The acreages in Exhibits D, E, and L have been revised accordingly to 120.75 acres. <br /> 7. Exhibits C-1 and C-2 Vegetation: Rule 6.4.3(e) requires the type of vegetation present in the affected <br /> area. Given the more complex revegetation plan, showing the existing types of vegetation at the edges <br /> of the disturbance may be critical in the assessment of the revegetation plan. Please resubmit C-1 or C-2 <br /> showing the types of vegetation. <br /> Response: A description of the vegetation in the vicinity of the mine and a map showing the adjacent <br /> vegetation communities was included in the Amendment 03 Exhibit C. Exhibit C-5 has been included to <br /> show the primary vegetation type within the permit boundary. <br /> 8. Exhibit C-3 Cross-Sections:These four cross-sections are called out on both Exhibits C-1 and C-2 <br /> (existing and post reclamation topography). Please resubmit C-3 with clarification as to which lines <br /> represent existing topography and which are proposed final reclamation. <br /> Response: Exhibit C-3 has been revised to include labels for the existing and reclamation topographies. <br /> 6.4.4 EXHIBIT D—Mining Plan <br /> 9. Fill Compaction, p. D-3:The first and last discuss fill lifts and compaction.Given the critical nature of <br /> the fill as buttress material for the existing slide,The DRMS requires material and compaction <br /> specifications for the fill material to ensure acceptable material is placed and compacted to an <br /> appropriate density. Please provide material and density specifications and discuss how the appropriate <br /> backfill density will be achieved using the proposed three-foot lifts. <br /> Response: The text in Exhibit D has been revised to include material and compaction specifications and <br /> associated geotechnical laboratory testing of the fill material. <br /> 10. Fill Monitoring, p. D-3:The third paragraph mentions future monitoring.The DRMS assumes this is a <br /> reference to slope stability monitoring. Please describe the duration,frequency,and reporting of <br /> reclamation slope stability monitoring, as well as criteria for demonstrating the slope will be stable. <br /> Response: The text in Exhibit D has been revised to include monitoring specifications and slope stability <br /> criteria. <br /> 11. Commitments:The DRMS accepts the following two commitments on p. D-4: <br /> a.Technical Revision submittal to address additional grading for potential supplemental <br /> imported fill in the Lower Borrow Area. <br /> Pikeview Quarry Amendment 4, Response to Adequacy <br /> December 11,2019 <br />
