volumes listed are probably not accurate. Please review topsoil replacement Tables 58 -62 and update the topsoil replacement volumes as necessary to reflect the reclamation that was completed at the Williams Fork Mines in 2008 and 2009. a. MCM Response: The referenced soil replacement tables have been reviewed and updated, as appropriate, to reflect recent reclamation activities. Copies of the updated tables accompany these responses for replacement in the PAP. b. DRMS Response: i. Revised Table 59 lists the acreage for the 5A Portal and Pond 5A -P2 &3 under the "depth" column of the table. Please correct this table and indicate the depth the material will be placed over this area. ii. Revised Table 60 indicates the same volume of material exists in each of the topsoil stockpiles as is currently listed on this table and does not appear to account for the 2008/2009 reclamation of the No. 9 Portal and Waste Disposal pile. The revised permit text indicates this area was reclaimed and cover material and soil material were placed over the area. Please explain this discrepancy and/or revise the tables to account for the completed reclamation. c. MCM Response #2: The referenced tables have been revised to address the noted concerns, and the revised tables are included with these responses. d. DRMS Response #2: i. The Division did not receive a revised Table 59. This item remain outstanding. Please address item 10(b)(i) above. ii. Item #10(b)(ii) is resolved. e. MCM Response #3: The revised Table 59 accompanies these responses. f. DRMS Response #3: This item is resolved. 14. Permit page 2.05 -24 includes a section on Backfilling and Grading that references Map 29, which shows the areas to be backf lled and graded, and Table 63, which gives backf ll volumes. Based on the recent reclamation at the site and the anticipated future reclamation, please review Map 29 and Table 63 and update them accordingly. This updating should be done in conjunction with the creation of the detailed reclamation plan requested in question 12 above. a. MCM Response: The referenced Permit backfilling and grading map and table have been reviewed, revised, and updated, as appropriate, to reflect recent site reclamation activities. Copies of the revised map and table accompany these responses for replacement in the PAP. b. DRMS Response: i. Revised Map 29 does not depict the cross - sections that are discussed in this section of the permit and the contour lines do not show adequate detail to depict the post mine topography. Also, the legend does not cover all the symbols used to depict features on the map. Please see the adequacy review section Rule 2.05.4 — Reclamation Plan above, specifically Item #1.
