26. The majority of the PAP maps display numerous symbols and shaded azeas, few of which
are defined on any of the maps. Please review all of the permit application maps and
provide legends for each map, which include all symbols, patterns, and colors
represented.
27. There appears to be a considerable amount of information in the old sets of permit
application binders that did not get carried forward to the currently approved permit
application binders. Please review and compare the three sets and make appropriate
revisions to ensure that all pertinent information is maintained in the currently approved
binders.
28. Sections 2.05.2 and 2.05.3 contain identical text, yet are labeled as "life of mine" and
"operation area". Please review these sections and replace whichever section is incorrect.
4.05 HYDROLOGIC BALANCE
29. Information presented in the Hydrologic Reclamation Plan -Section 2.05.6(3)(b)(v) of the
PAP is not consistent with the discussion of timeframes for lowering of TDS levels in
spoil-water discharge presented in Section 2.05.6(3) -Protection of the Hydrologic
Balance. On page 2.05.6(3)(b)(v)-1, WFC states that: "Replaced spoil is expected to
impact ground water quality for about 25 yeazs when the discharge quality will reach pre-
mining TDS of 1000 mg/I and surface level of 500 mg/1. Because of these findings, no
special handling of materials is anticipated for mining operations conducted", This is not
consistent with the detailed analysis presented in the Protection of the Hydrologic
Balance section of the PAP, where it is shown that elevated TDS in spoil water can be
expected to last hundreds of years. Please revise the Hydrologic Reclamation Plan and
the Protection of the Hydrologic Balance sections of the PAP accordingly to reflect
consistent and correct information.
30. WFC indicates in the Section 2.05.4(2)(c) that Ponds 007, 008, and O10 will likely remain
as stock ponds after reclamation. These ponds have not been approved as permanent
impoundments. In addition to landowner approval, WFC must provide complete
permanent impoundment demonstrations in accordance with Rule 4.05.9(13) (a) through
(f). Landowner approval for Pond 007 and 8 are contained in the PAP. If WFC intends
to retain Pond 007, 008, and 010 as permanent, please provide landowner approval for
Pond 010 and permanent impoundment demonstrations as required by Rule 4.05.9(13)
for each impoundment.
31. As indicated in Item 11 above, design information is provided for only one SAE in
Attachment 2.05.3(3) 7. However, there was no sedimentology demonstration provided
with this design. A sedimentology demonstration is required to demonstrate compliance
with 4.05.2. Please provide a sedimentology demonstration for the SAE at Topsoil Pile
"K" (Due West of 007 Pond).
