It is unknown how many of the identified wells are still in operation today. Some of the wells
are large capacity, irrigation wells with the majority being small capacity wells. It is unknown
if any of the wells provide domestic water to the owner, however, given the poor water
quality in the area, it is unlikely that water from this aquifer serves as a potable supply. The
operator proposes to monitor the groundwater table as follows:
A monitoring grid will be located azound the property. A total of 6 monitoring points
will be established with baseline data collected prior to the start of mining. The
baseline information will consist of at least three sets of water table measurements
being made before mining starts. The measurements will attempt to collect data
during different times of the year to allow for fluctuations that normally occurs, such
as deep water percolation for irrigation, etc.
The operator will monitor the water table on a monthly basis for the life of the mine.
The water table data shall be supplied to the Division of Minerals and Geology
(DMG) with the annual report.
Project Water Requirements
The proposed minittg operation will consume water from plant operations, lake evaporation _..f
from exposed groundwater, and moisture loss in materials transported from the site. M'"
The water losses will be accounted for in an approved Substitute Water Supply Plan (SWSP)
submitted to the State Engineer's office. A copy of the approved plan will be submitted to
the DMG when it is received. ~~ ,,~.+ ^,~TS'P
Water Quality "' ~ ~ n gLBS~"°'~
The proposed mining operation will not adversely impact water quality to either groundwater
or surface water. All discharges from the site will be regulated by the Colorado Department
of Public Health and Environment through an NPDES permit. The terms and conditions of
the permit are anticipated to be those normally used in the Nationwide Permit system. A copy
of the discharge permit will be supplied to the DMG when it is issued. ~-~~~~~
M'~ C1r'ILY~`n`G'
The proposed mining operation and aggregate plant do not use any chemicals or flocculants ~`°~ ~~
in the process. There is no reason for water quality monitoring to be required of the Np~E
groundwater in the area. The proposed monitoring program for the water table is adequate ~/ ,Q.~3_,
to protect the groundwater resources in the area.
