f GW-3 Conductivity -f-GW-3 Baseline - Mine Water Average
There is a field (designated AVF-1) to the south and west of East Salt Creek shown on
Figure 4.1-2, where the landowner is attempting to raise grass. As explained earlier in
this section, and according to the Division's 1987 Material Damage guidelines, mine
discharge does not add salinity to the already high values, rather, can only lower the
salinity in SW-1 and GW-3 during the irrigation season. By improving the salinity in
East Salt Creek surface waters and the alluvium groundwater, downstream farmers,
including those farming in AVF-1, will not suffer loss of production due to the addition of
mine discharge.
Recently, the local rancher developed a well in the alluvium of East Salt Creek. The
water from the well was so poor that it could not be used for any beneficial purpose.
There are about five domestic water users in the area. Each must truck water over 20
miles to the area for domestic use. This preponderance of evidence that the
groundwater is unusable would indicate that even if the groundwater from the mine did
mix with the groundwater of the East Salt Creek alluvium, no detrimental effect would
occur. East Salt Creek is an accurate name.
Approximately three acres of disturbance will occur on the alluvial valley floor of East
Salt Creek. Two acres of disturbance will occur from the proposed sediment pond and
topsoil stockpile that are part of the new surface facilities associated with the expanded
Coal Mine Waste Pile. One-half an acre of AVF disturbance occurred when a ranch
