6.4.12 Exhibit L-Reclamation Costs
22. The reclamation cost estimate provided by the Applicant is from 1998 and includes the cost
of reclaiming the Rex Quarry(M-1977-304). Also,the defined mining and reclamation phases
at both the Owl Canyon Quarry and the Rex Quarry have been revised. As a result, this
information is not sufficient for the Division to complete a reclamation cost estimate for the
Owl Canyon Quarry. As required by Rule 6.4.12(1),the Operator must provide all information
necessary to calculate the costs of reclamation that would be incurred by the state. The
Division requests the following information:
a) Specify the maximum number of acres that will be disturbed; all reclamation calculations
must be based on the maximum allowed disturbance. (The 2013 Annual Report states
there is currently 93 acres of affected land)
b) Specify overburden volumes to be backfilled, push/haul distances and the grade of all
haul routes.
c) Specify topsoil/waste sand volumes, push/haul distances and the grade of all haul routes.
d) Specify the total length, height and grade of all highwalls to be reduced.
e) Specify the length and width of all roads to be reclaimed.
f) Specify number of acres requiring final grading.
g) Specify number of acres requiring revegetation.
h) Specify the type of equipment to be used for each reclamation task.
PLS Response:Please find the information below.
a. Concurrent reclamation is included in the mine plan. Therefore,the maximum
acreage allowed for disturbance will be a combination of reclaimed and
currently disturbed and unreclaimed land. However, the affected land
boundary is 270 acres.
b. Concurrent reclamation is included in the mine plan. The average grade is 5 to
8%for haul roads. The average push pull distances will be 500 feet.
c. No waste sand will be used. The minimum topsoil depth will be 2 feet. The
average push/pull distance will be approximately 500 feet with an average grade
of 6%.
d. The high walls will have the following characteristics. The height will range
from 85 to 90 feet, the length will be approximately 3,100 feet, and the average
grade to reduce the highwalls to will be 6%.
e. Roads within mining boundaries are not included as these will be reclaimed
during backfilling activities. The perimeter roads will not reclaimed to allow
for well access.
f. The approximate acreage requiring final grading will be 187 acres.
g. The approximate acreage requiring revegetation is 187 acres.
h. A D9 Dozer will be used for rough grading. A 16H Moter Rader will be used
for final grading. A DIO dozer will be used for ripping. A 637E push pull
scraper will be used for material placement in growth media application.
