The Division of Reclamation, Mining and Safety (DRMS) has reviewed the application for a technical
revision to the above referenced 112 permit. The purpose of the technical revision is to update the mining
phase sequence and maximum allowable disturbance for the operation. The site is a 40 acre 112c
operation with a current maximum allowable disturbance of 20.6 acres. A review of the application has
revealed a few issues and clarifications to address.
1) According to the map submitted with the technical revision the stockpile locations shown on the
map indicate that the overburden and topsoil are stockpiled together. Per Rule 3.1.9(1), where it
is necessary to remove overburden in order to mine the construction material, topsoil shall be
removed and segregated from other spoil. Please clarify whether or not the topsoil is mixed with
the overburden. In the case that the two are mixed provide an explanation of what measures will
be implemented to separate the topsoil from the overburden.
2) Please clarify what phases remain to be mined. The figure provided does not indicate what areas
remain to be mined or what area is currently disturbed. Please clarify what acreage of
disturbance currently exists at the site.
The technical revision cannot be approved until the issues are adequately addressed. Please submit a
response to the issues as soon as possible but no later than November 28, 2011, so the decision date of
December 16, 2011 can be met. If your response, or a written request for an extension of the decision
date, is not received by November 28, 2011 then the request for the revision may be denied.
If you need additional information, please contact me at the Division of Reclamation, Mining and Safety,
