6.4.4 EXHIBIT D — Extraction Plan
Of the total 203.61± acres of potential extraction, the resulting basins will
function as multiple-use reservoirs with a slightly fluctuating combined water
surface area covering 187.66± acres. The remaining balance of 37.3± acres of
land above the anticipated high-water marls of the reservoirs, and not otherwise
committed to existing or planned structures or infrastructure over the parcel,
will be stabilized with vegetation; including the anticipated 15.95± acres of
basin slopes reflected in the total.
NOTE: Shoreline irregularities and fill to establish and enhance the aesthetic
and end-use functions of the resulting basins shown on Exhibit F: Reclamation
Plan Map, are illustrative only, as this effect as to location and extent will be
field-fit where practical, and may substantively different from that portrayed
under the application. The actual location and extent will be identified in
subsequent OMLR Annual Reports, and absent there, at the time of any
applicable release of a location in part or whole from the permit. Since
representations cannot be accurately portrayed in advance, Exhibit F simply
identifies the near maximum extent [typical] of the resulting basins or ponds
and the potential for shallows during lining and finished grading.
The estimated timetable for extraction, commencing approximately spring to
winter 2023; is estimated to take 23-28± years combined, or longer, followed by
an additional five years to complete reclamation; or a total estimated life of the
mine of 28-33± years; ending approximately winter 2051 to 2056. This is a life
of the mine operation and all timetables are estimates and may prove shorter
or longer than stated. The final determination will occur five years after the
deposit is exhausted and all marketable product has been removed and
necessary infill completed at the location to the point of final reclamation as
approved or modified under the terms of the permit is completed.
This submittal is unable to fully forecast the maximum extent of affected
land expected at any given point in time, beyond an annual basis. As
operational extraction and reclamation efforts will vary annually, the timing
of extraction, reclamation, and life of operation as forecasts must be based
on an initial estimate [refer to Exhibit L - Reclamation Costs], then
subsequently verified and adjusted as reasonably determined at the time of
the required OMLR Annual Report. If justified by field conditions, a rider to
the warranty would follow in due course to reflect current or forecast
conditions where such conditions cannot be reasonably attenuated in a
timely manner prior to the due date of the next year's Annual Report. This
will serve to assure flexibility and confidence in continued operations until
completion of the desired end use.
Additional information on the reclamation and restoration of affected lands is
identified under Exhibit E: Reclamation Plan. All reclamation will follow
