Mr. Jerald Schnabel <br /> November 24, 2019 <br /> Page 2 <br /> 3. Item 11, p. 3: Correspondence information. The DRMS Permittee is Continental Materials <br /> Corporation(CMC),not Castle Aggregate. Please describe the relationship between CMC and <br /> Castle Aggregate. <br /> 6.4 SPECIFIC EXHIBIT REQUIREMENTS—REGULAR 112 OPERATIONS <br /> 6.4.3 EXHIBIT C - Pre-mining and Mining Plan Map(s) of Affected Lands <br /> 4. Exhibits C-1 and C-2 Owners: Rule 6.4.3(a) requires all adjoining surface owners of record <br /> be identified on the Exhibit C Map. No owners are identified on either Exhibit C-1 or C-2. <br /> Please resubmit C-1 and/or C-2 showing adjoining surface owners of record. <br /> 5. Exhibits C-1 and C-2 Topography: Rule 6.4.3(c) requires topography and contours. Both are <br /> provided,however there are several references to specific elevations in Exhibit D Mining Plan, <br /> Exhibit E Reclamation Plan, and Exhibit L Reclamation Costs. Please resubmit C-1 and C-2 <br /> showing contour labels and identifying contour intervals. <br /> 6. Exhibits C-1 and C-2 Involved Area: Rule 6.4.3(d) requires the total area involved in the <br /> operation be identified. There are green lines outlining various areas for which the Legend <br /> identifies as "Disturbance Area". However, some topsoil stockpiles and roads are shown <br /> outside these disturbance areas. Topsoil stockpiles are considered affected area as are all roads <br /> that will not be reclaimed. Please resubmit C-1 and C-2 with the topsoil stockpiles and all <br /> roads to be reclaimed included in the "Disturbance Area". Please provide the disturbance <br /> acreage on the re-submitted map(s). If there are roads that are not to be reclaimed, please <br /> provide rationale for why they do not need to be reclaimed. <br /> 7. Exhibits C-1 and C-2 Vegetation: Rule 6.4.3(e) requires the type of vegetation present in the <br /> affected area. Given the more complex revegetation plan, showing the existing types of <br /> vegetation at the edges of the disturbance may be critical in the assessment of the revegetation <br /> plan. Please resubmit C-1 or C-2 showing the types of vegetation. <br /> 8. Exhibit C-3 Cross-Sections: These four cross-sections are called out on both Exhibits C-1 <br /> and C-2 (existing and post reclamation topography). Please resubmit C-3 with clarification <br /> as to which lines represent existing topography and which are proposed final reclamation. <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 <br /> nature of the fill as buttress material for the existing slide, The DRMS requires material and <br /> compaction specifications for the fill material to ensure acceptable material is placed and <br /> compacted to an appropriate density. Please provide material and density specifications and <br /> discuss how the appropriate backfill density will be achieved using the proposed three-foot <br /> lifts. <br /> 10. Fill Monitoring,p. D-3: The third paragraph mentions future monitoring. The DRMS assumes <br /> this is a reference to slope stability monitoring. Please describe the duration, frequency, and <br /> reporting of reclamation slope stability monitoring, as well as criteria for demonstrating the <br /> slope will be stable. <br /> C"Users�TC1,Documents'',,Projc,tsl_EI Paso\M-77-211 Pikeview Quarry\AM-04 ReviseRechPAR-2019-11-24_M-77-211.docx <br />
