The Division of Minerals and Geology (Division) has received your documentation for Technical
Revision-02 ("TR-02") for the Chambers Pit, Permit No. M-1980-136. The purpose of the
revision was to request permission to begin mining of AREA E under the existing permit, and to
request a recalculation of the reclamation bond to include AREA E. However, after review of
the documentation submitted for the TR, several issues need to be addressed before the bond can
be recalculated and TR-02 approved. The issues to be addressed by the operator aze outlined in
the following paragaphs.
1. On June 13, 2003, the Division approved the release of AREA A in AR-Ol. This AR
reduced the total acreage for the permit from 149 acres to 135 acres. In TR-02, Exhibits C
and F (Pre-Mining and Mine Plan Map and Reclamation Plan Map) do not reflect the acreage
reduction. Please resubmit Exhibits C and F to show the new permit boundaries following
the acreage reduction.
2. The mining plan indicates that topsoil and overburden will be stockpiled within the mining
area. However, no topsoiUoverburden stockpiles aze shown on Exhibit C, Pre-Mining and
Mine Plan Map. Please include ]orations of topsoiUoverburden stockpiles when resubmitting
Exhibit C as requested in Item No. 1 above.
3. The irrigation ditch shown in AREA E on Exhibit C appears to be relocated on Exhibit F.
Who is the owner of the ditch and does the operator have permission to relocate it? If the
operator does not own the ditch, the operator needs to provide proof that he has permission to
relocate it.
4. Numerous manmade structures aze located either inside the proposed mining area or within
two hundred feet of the proposed mining azea. These structures include, but aze not limited
to, the baseball fields and associated fences, Fairgrounds Road and associated utilities, the
buildings in the northeast comer of AREA E, and the existing/relocated itrigation ditch. In
accordance with Rule 6.4.19, please provide information sufficient to demonstrate that the
