10. Permit page 2.05 -20 discusses topsoil replacement on the site and references Tables 58 -62, which are
topsoil replacement tables. There are no dates listed in the footer for when these tables were created
but, given the reclamation performed at the site in 2008 and 2009, the topsoil replacement 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:
L 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 was 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 considered resolved.
14. Permit page 2.05 -24 includes a section on Bacljilling and Grading that references Map 29, which
shows the areas to be backjilled and graded, and Table 63, which gives backjzll 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.
