Docusign Envelope ID:45B9721C-FDE2-4821-B686-80BBC79CA6DD <br /> hatching shows the South Cresson Pit as inaccessible while F-1 correctly identifies <br /> accessible areas for growth media placement at least prior to TR142. <br /> • Exhibits F-1 and F-6 have been revised and are included in (Attachment 4). <br /> f. The southern portion of the Main Cresson Mine shows a 47-acre cross-hatched area <br /> where trees will be planted. Please confirm the topography of this area as it appears <br /> this would be a partially backfilled highwall area with a north-facing slope which would <br /> receive the tree plantings, however the contour lines depict a highwall that has not <br /> been backfilled. <br /> The tree planting area has been modified to show that trees will not be planted in the highwall area <br /> (Map F-6). <br /> g. Maps F-4 and F-7 show a VLF2 slope arrow which is parallel to the contour lines and <br /> not perpendicular. Please review and revise Exhibit F Map slope arrows. <br /> Slope arrows have been modified in the revised maps (Attachment 4). <br /> h. With modifications to the post-mining topography from the VLF expansions, please <br /> review the shape and size of the proposed tree planting areas. Please also review the <br /> site's topography and the reclamation plan criteria for tree planting to determine if new <br /> areas have been created which could now be planted with trees. <br /> Comment acknowledged. Tree planting areas have been reviewed. <br /> i. The Carlton Tunnel area and the AM14 Grassy Valley monitoring well access road are <br /> not shown on any of the Exhibit F maps. <br /> • Map F-5 has been modified to show the Grassy Valley monitoring well access road, and a new Map F- <br /> 9 has been prepared to show the Carlton Tunnel area (Attachment 4). <br /> Exhibit G—Water Information (Rule 6.4.6): <br /> 19. Within Section 2.2, Paragraphs 2 and 3,the volcanic diatreme is discussed. It is stated <br /> Figure G-1 shows no significant groundwater usage occurs in the area of the diatreme. <br /> Please add in the diatreme boundary to the Figure G-1 and Figure G-2 plate series. <br /> The diatreme boundary has been added to the Figure G-1 and G-2 plate series. These figures are <br /> included in (Attachment 5). <br /> 20. Please revise Table G-2 Surface Water Monitoring Parameters and Table G-5 Groundwater <br /> Monitoring Parameters to include the applicable standards each analyte is compared to. <br /> Please note,the Operator may include for certain drainages/analytes a footnote that <br /> acknowledges they are working with CDPHE on potential surface and groundwater site- <br /> specific classification issues to address the potential impacts the site may have on these <br /> systems. <br /> Exhibit G has been updated to include the applicable standards for each analyte. This information has <br /> also been previously submitted to DRMS in the CC&V Water Monitoring QAPP. <br /> 21. Please include the Carlton Tunnel,the affected lands boundary which surrounds it, and <br /> applicable features within 2 miles on the Figure G-1 and Figure G-2 plate series. <br /> A new plate has been added to Figures G-1 and G-2 to show the Carlton Tunnel area and applicable <br /> • features within 2 miles of the affected lands boundary(Attachment 5). <br /> SSR Mining Inc.
