(5) On amended page 26 of Appendix 3.3-3a, the consultant commits
to the development of a monitoring program to verify
embankment stability ..in the final design phase of the
project and adjusted during construction as necessary." Our
eventual findings will reiterate this commitment on page 26
of Appendix 3.3-3a, verbatim. It will be necessary to
stipulate a specific timeframe by which this plan for
monitoring the embankment stability of the proposed coal
procesing waste structure must be developed and implemented.
We cannot wait until the life-of-mine, 300' high
configuration, is achieved to determine the slurry
embankment's slope stability.
(6) On page 27 of the original version of Appendix 3.3-3a, the
consultant recommended ..the engineering characteristics of
the coal refuse be evaluated once sufficient quantities of
refuse are available. A reevaluation of the design of the
embankment should be undertaken when the properties of the
coal refuse are known." Approval of the embankment plan will
include a stipulation requiring both the completion of the
material testing and the verification and/or amendment of the
engineered designs for the structure.
In summary, the applicant has submitted the majority of
information required to comprise a "general plan" for the coal
processing waste embankment, as described in Rule 2.05.3(S)(a).
With the addition of a "certification statement that includes a
schedule setting forth the dates that any detailed design
plan...will be submitted to the Division", the general plan would
be complete. Amendment of the design to yield the required
seismic safety factor (see comment (1) above) would then render
the general plan technically adequate. The applicant has not,
however, completed a "detailed design plan", as described in
that same rule.
in the alternative, the applicant could pursue phased approval of
the coal processing waste embankment structure. In order to
pursue this approach, the application would have to be amended to
include appropriate stability analyses for each of the separate
phases' configurations, such as that of the starter embankment."
SRM Response:
Storm Ring Mines will pursue a phased approach to the design and
construction of the coal processing waste (refuse) embankment
structure. Prior to beginning any construction on the Phase "B"
refuse embankment or supporting facilities, Storm Ring Mines will
accomplish the following:
