M-96-050; Permit Application Adequacy Revi ew MichaelB Long
D rvnion Direaur
Dear Mr. Snook:
The Division has completed its initial adequacy review for Permit
No. M-96-050. The application was submitted on June 26, 1996 and
was initially called incomplete via DMG letter dated June 28, 1996.
The requested information was submitted on August 6, 1996 and the
application was called complete on that day. The decision date for
this application is September 5, 1996. The application is
generally adequate and well organized, however; there are a few
areas that will require the submittal of additional information or
clarification of the existing information.
Exhibit C-Mininq Plan
Under items (h) and (i) in this section, the narrative refers to
encountering groundwater, yet no well permit or augmentation plan
has been referenced. Prior to approval, clearance from the state
engineers office will be required. A letter from the Office of the
State Engineer detailing this requirement is enclosed. If there is
no clearance, the reclamation bond will calculated to include
backfilling the pit to prevent exposing groundwater after
reclamation. With the current information in the permit, the
Division is unable to determine what level the water would be
exposed. Therefore, the bond would have to be calculated to
include total backfill unless it can be determined what level of
backfill will be necessary to prevent groundwater exposure once
reclamation is completed.
Exhibit D-Backfill and Grading
There is some inconsistency with the proposed final slope
gradients. The reclamation map indicates that backfilled slopes
will be no greater than 3H:1V, however; the narrative in Exhibit D
states that maximum gradient of slopes will be 2H:1V. If reclaimed
slopes of steeper than 3H:1V are proposed, the operator must
include a justification that supports the steeper slopes for the
proposed post-mining land use in accordance with rule 6.3.4(1)(b).
The Division prefers 3H:1V or flatter backfilled slopes for
reclamation purposes due to the reduced erosion hazard and
