As this short summary of Table 12 shows, the maximum evaporation will occur in 2013 and
2014. Table 12 also shows that drainage where each pond is located so replacements can be
made to that drainage. There are not any water rights in Coal Canyon that will be affected by the
mining operations.
For the irrigation season of April through October, evaporative depletions can either be
augmented by storage releases out of the ponds or from CU credits. There are excess CU credits
for May through September. During the non - irrigation months of November through March, the
ponds would operate in priority or evaporation depletions would be replaced from pond releases.
Since the average temperature is less than 32 degrees in December, January and February, the
evaporation is calculated to be zero.
Ponds 9, 14 and possibly 15 are only used during storm events to capture runoff water before it
leaves the mine permit area. Any water stored is only kept for few days before being released.
Consequently, the evaporation is zero for these dry ponds. Because Pond 15 is just being built, it
is not know if it will be dry or not, so it was included in the evaporation tables with a small 0.5
surface acres.
The exact location and size of the ponds in the Cyprus area are not know and are not included in
the evaporation calculations. Some of the current storage rights may be transferred to the Cyprus
area if needed.
NOTE: The next three areas of Domestic Use, Well to Well Injury and Impacts to Surface
Water Rights from Mine Pumping were completed and explained in a letter report completed by
Chris Sanchez of Bishop Brogden Associates, Inc on August 25, 2010 ("BBA Report").
