of which 56.50 acre feet of depletions will occur during the Historic Call Period. The
net evaporative depletions are summarized on the Water Balance tables attached
hereto as Tables A-1 and A-2.
(II) Water will be withdrawn from the Custam Crushing Pits as product
moisture and for aggregate washing purposes during mining operations. The product
mined from the Custom Crushing Pits will include product moisture in the amount
of four percent (4%) of the material mined during the yeas, and water will be pumped
from the Custom Crushing Pits (or a settling pond located adjacent thereto) at the
maximum rate of 1,500 g.p.m. for aggregate washing purposes. Of the total amount
of water withdrawn and diverted as product moisture and for aggregate washing
purposes, 2.96 acre feet per year will be depletions Ito the river system. The
remainder of the amount diverted for aggregate washing 'll be discharged back into
the Custom Crushing Pits or into the Colorado River adjacent to the Pits. The
diversions and depletions for product moisture losses and aggregate washing could
occur at various times during the yeaz, both during and outside of the Historic Call
Period.
(III) Water will be pumped from the Custom Crushing Pits at the
maximum rate of 150 g.g,m. for dust suppression purposes in connection with gravel
crushing activities. Applicant anticipates that a total of X0.66 acre feet of water per
yeaz will be diverted for dust suppression purposes, and that such amount will be
totally consumed.
(I~ During mining, the Custom Crushing Pits will be dewatered at a
maximum rate of 5,000 g.p.m., with the water being discharged to the Colorado
River. However, these dewatering operations will not i sult in any depletions in
addition to those described above.
(V) Evaporation losses from the Custom Cnishing Pits will occur both
during mining operations and after mining operations laze completed. All other
diversions and depletions will occur only while mining operations at the Custom
Crushing Pits aze ongoing. Once mining operations have been completed at the
Custom Crushing Pits, these other diversions and depletions will cease. Total
depletions during the Historic Call Period will not exceed 160.12 acre feet, as set forth
on the Water Balance table attached hereto at Table A-1 ~
D. Applicant is entitled to certain depletion credits (collectively referred to herein
as the "Depletion Credits") in connection with the development of the Custom Crushing Pits
and with respect to the water rights described in Paragraph 14, ab~, ove, described as follows:
