local hydrologic regime. Additionally, since there are no known
• water rights adjudicated for this aquifer, there is little chance
that water interests are being injured.
lIUNGER CANYON tlINE
To date there has been no water encountered by this mine;
therefore, it is assumed that there has been no effect on the
hydrologic regime of the area. A current mine workings map is
included as Figure 5 and Table 2 shows that there was no water
imported or used at the mine in 1986.
EFFECT OF TFIE !LINES ON T[~ EAST SALT CREEK REGIlIE
Surface Water
Due to the limited disturbance of the mines there is little chance
that any significant effect on the quantity or quality of the
surface waters near either mine sites has occured. As the
Division notes in its approval package for the Munger Canyon Mine,
the total area that will be disturbed by both mine sites amounts
to 0.12 percent of the area of the East Salt Creek drainage basin
above the mines. The approval packages also allowed Salt Creek to
reduce its monitoring program since any additional information
gathered while the mines are idle will be essentially baseline
sampling.
• Results of. 1986 quarterly sampling for monitoring sites SW-2
(McClane Creek) and SW-3 (Munger Creek) are shown on Table 3. The
results are highly variable as was the case with the baseline
data.
Groundwater
Under the reduced sampling program, Salt Creek is required to
monitor only well GW-6 at the proposed waste rock disposal area.
The well has been dry since installation. Another well installed
in the alluvium near the mouth of Munger Canyon, GW-5, has also
been dry since installation (November 1981). These results
confirm the absence of groundwater in Munger Canyon.
To respond to Stipulation 4 of the Central Facilities Revision to
the Munger Permit, Salt Creek collected an additional year of
baseline groundwater monitoring. The results of data collection
were submitted to CMLR quarterly and a minor modification to the
permit evaluating the data was submitted in March of 1987. The
modification was approved on April 7, 1987.
The stipulation response details groundwater levels and quality
from September of 1985 through September of 1986 when the proggam
was terminated. A discussion of the results is contained in
• Volume VI of the Munger Canyon Permit on pages 4-14a and 9-14b.
Table 9.2-2s of the same volume details data collected for all
monitoring wells but GW-1, whose results are shown on Figure 4 of
this report.
