given time is 2.86 acres. The worst case scenario for topsoil replacement will occur when
mining operations are being conducted within Mine Areas 2, 3, and 4. Table 1 lists the areas
requiring topsoil replacement and the associated acreage values:

9. Table D-1 of the Mining Plan breaks down the various types of disturbance which will occur
on the north and south sides of the Middle Fork of the South Platte River (River). The types
of disturbance for the area north of the River lists 0.18 acres associated with the old highwall
and Settling Pond 3. Exhibit C-2: Mine Plan Map shows the old highwall and Settling Pond 3
on the south side of the River in Mine Area 4. Please clarify the location of the old highwall
and Settling Pond 3 and revise Table D-1 as necessary.
10. Table D-1 of the Mining Plan specifies that the water holding pond and surge pond account
for 0.3 acres of disturbance. However, Page E-2 of the Reclamation Plan states that the water
holding pond and surge pond will be 0.36 acres. Please clarify this discrepancy and make the
necessary revisions to the appropriate Exhibit.
11. The Mining Plan states on Page D-21 and D-22 that the total area disturbed at any given time
will be 0.9 acres of affected land for the active mining area and 1.6 acres of ancillary
disturbance, which would result in a total disturbance of 2.5 acres. However, the Mining Plan
states the maximum disturbance at any one time is 2.02 acres. The Division has determined
the maximum disturbance at any one time could be up to 2.86 acres; see additional comments
under Item No. 8. Please provide a description of the ancillary disturbance and provide a
justification for a maximum affected area of 2.02 acres.
12. The Mining Plan states on Page D-6 that all gold bearing gravel south of the River will be
processed at the South Location, located on relatively flat ground west of the
office/residence. Please clarify if Settling Pond 3 will be utilized in the processing of gold
bearing gravel. If so, please demonstrate that there will be enough room to contain the wash
plant equipment, product stockpiles and wash fines such that all associated disturbance is
located outside of the 100 year floodplain.
