RE: Third Party Comments Received, Gold Hill Mill, File No. M-94-117
Dear Mr. Hartley:
Please find enclosed a copy of correspondence from the Committee on Mining
and the Environment, Gold Hill Town Meeting, Inc. (Committee) regarding
the above referenced application. This is provided to you in accordance
with Rule 1.7 of the Mineral Rules and Regulations of the Mined Land
Reclamation Board. Rule 1.7 also requires that the Division of Minerals
and Geology consider third party comments received in the review of a
permit application. The Committee has raised a number of pertinent issues
that will have to be adequately addressed before the permit application
can be approved. These critical issues are listed below.
1. Given that a loss of containment has occurred through the door at
the northwest corner of the mill building, the Division concurs with
the Committee that measures need to be implemented to prevent a
reoccurrence. Such measures could be installation of a concrete
sill such as that proposed for the man-door in the lower part of the
building.
2. The Division concurs the Committee that water and other lines should
be checked prior to mill start-up after a period of inactivity.
Please commit to pre-operational inspection and testing of all
critical systems prior to mill start-up, and commit to recording all
pre-operational inspection observations in the mill log book that
COM, Inc. has previously agreed to maintain.
3. The Committee has raised the issue of erosion prevention on the
downstream tailing embankment face. It is the Division's view that
the prudent erosion prevention method for the dam face is to
implement the approved reclamation plan on this area upon completion
of embankment construction. Please commit to such implementation.
4. As you know from previous correspondence, the Division shares the
Committee's concern that topsoil be effectively salvaged at the
