has ruled this material needs to be incorporated into a mine reclamation permit. The
Board Order is attached. Please discuss where this material is to be used in reclamation
and include its location on Exhibit C, and Exhibit F if appropriate.
6.4.6 EXHIBIT F — Reclamation Plan Map
19. There is a dry pit shown on the west end of the proposed permit area. No discussion of
this pit being left open was provided. There is a potential for this open pit to collect
stormwater. Please be aware that any collected stormwater must be released or infiltrate
within 72 hours. The Division requires the following specific reclamation information for
this dry pit:
a. Depth,
b. Side slope,
c. Revegetation — side slopes and bottom,
d. Stormwater interception and retention duration estimate.
20. There are no developed water resource features shown on the reclamation plan map. If
the Applicant intends to pursue the phased bond approach, the ultimate reclamation
configuration needs to be presented in this application or an amendment application will
be required prior to initiating the previously discussed developed water resource features.
Please provide the following information on Exhibit F:
a. Grading plans showing final reclamation slopes,
b. Which areas are to be reclaimed as rangeland, which are water storage,
c. Locations of proposed pipelines and discharge points (if applicable).
21. Section 3.1.5(1) Grading indicates materials excavated for the Excelsior Ditch relocation
may be used for the construction of permanent visual berms. Please show these berm
locations on Exhibit F, or commit to submitting either an amendment application or
technical revision, to be determined through consultation with the Divison, prior to
constructing the visual berms.
22. Similar to Comment 2 above, the Exhibit F map implies Nyberg Road is intended to be
included in the permit boundary. Please clarify the Applicant's intent to include or
exclude Nyberg Road in the permit boundary on the map.
6.4.7 EXHIBIT G — Water Information
23. Section (1) Impact to groundwater — the second sentence indicates there is expected to be
some degree of impact on the groundwater flow regime. Please provide some discussion
on the impact the operation is expected to have on local well users (within 600 feet)
access to and quantity of groundwater.
24. There appears to be some discrepancy between text and Exhibit C — Mining Plan Map
and Phase One. The Exhibit C map indicates Phase One is the 9.7 -acre disturbance on
the west end of the proposed operation. Section (1) indicates the "Central Reservoir" is
