to the alluvial sediments along the various drainages. Other than
water rights filed on very old flowing exploration hole (SIC-2), no
uses of bedrock ground water have been identified. Ninety percent
of all wells in the area are less than 100 feet deep. All ground
and surface water rights within a two mile radius of the permit
boundary are listed in Table 3.3-1. water rights for the permit
area and adjacent lands are located to the nearest quarter/quarter
section on Figure 3.3-5.
Present uses of ground water include domestic and public water
supplies, stock watering, and irrigation. A water use column and
symbol explanation are provided in Table 3.3-1.
The nearest established water source to the permit and disturbed
areas are the Riverbend Subdivision wells which are located along
the Colorado River upstream from the proposed operation.
Operations at the Coal Ridge No. 1 Mine will not have any impact on
these wells since the wells are upstream from the permit area and
also within a tributary drainage which will not contain any mining
activity. The nearest developed surface water source is the Vulcan
Ditch which is owned by the Operator. The dicth originates in
Canyon Creek which is a tributary on the north side of the Colorado
River. The mining operation will not impact this water source.
Other private water sources occur north of the Colorado River and
are, therefore, isolated hydrologically from the mining activity.
The Colorado River is protected from mining impacts by Pond A which
is designed to catch runoff from the entire facility.
3.3.4.9 Proposed Monitoring Plan
Bedrock
The formerly operating monitoring system did not include any
bedrock wells, since the baseline conditions had been established
and operational monitoring had indicated that no changes had
occurred. The Operator had committed, however, to the drilling of
two holes into the Rollins Sandstone from within the mine. The
Division had agreed to this approach becuase of the expense and
difficulty in drilling holes into the bedrock given the steep dips
and rugged terrain. The Operator had also committed to properly
abandoning the existing bedrock will, SK-3H, providing the Division
with the appropriate report upon sealing.
Since the mine development was not completed, the obligation to
drill the holes from within the mine, has lapsed and there are no
plans, nor possibilities to do so.
