11. Commitments: The DRMS accepts the following two commitments on p. D-4:
a. Technical Revision submittal to address additional grading for potential supplemental
imported fill in the Lower Borrow Area.
b. Technical Revision submittal to address temporary haul roads necessary for
reclamation to be constructed in previously disturbed areas.
6.4.5 EXHIBIT E—Reclamation Plan
12. Topsoil Importation: The third paragraph on p. E-2 discusses importing topsoil for
reclamation. The importation of topsoil may have significant reclamation bonding
implications. Please provide an estimate for the required amount of imported topsoil and if a
source has been identified.
13. Subgrade: The first paragraph on p. E-4 discusses placing a "1.0-foot thick subgrade of
weathered granite" over areas where shot rock remains at the surface. Shot rock can have
significant void space. Please address the following:
a. Will a foot of weathered granite be sufficient to prevent topsoil from being lost to
void spaces in the shot rock?
b. Where is this extra material included in Exhibit L?
6.4.6 EXHIBIT F—Reclamation Plan Man
14. Exhibit F Proposed topography: Rule 6.4.6(a) requires topography and contours. Both are
provided,however there are several references to specific elevations in Exhibit D Mining Plan,
Exhibit E Reclamation Plan, and Exhibit L Reclamation Costs. Please resubmit Exhibit F-1
showing contour labels and identifying contour intervals, also ensuring the entire affected area
is included (Please see Comment No. 6 above).
15. Reve etation: Exhibit L, Worksheet No. 3 indicates 100 acres will require revegetation.
Exhibit L, Worksheet No. 14A indicates 108 acres will require reseeding.
a. Please explain the 8 acre discrepancy.
b. These 100 or 108 acres need to be identified in Exhibit F, and should include topsoil
and overburden stockpiles containing material to be used in the reclamation.
16. Exhibit F Final Land Use: Rule 6.4.6(b) requires showing the proposed final land use. Given
the more complex revegetation plan, it will be helpful in understanding the final revegetation
plan if types of vegetation in the disturbance area if these are shown. Please resubmit F-1
showing the different types of vegetation proposed.
6.4.6 EXHIBIT G—Water Information
17. Drainage Features: Various drainage features are discussed in Exhibit G, most of which are
not identified on any maps submitted in Exhibits C, F, or G. Please submit a map identifying
and showing the location of the following:
