Gypsum Ranch Pit SWSP Page 4 of 6
April 10, 2013
According to the decree in Case No. 2002CW211, The Gypsum Ranch Pit will be
reclaimed as a re- vegetated area when Lafarge has completed mining. The C M Stremme and
Gates Ditch water will be used on the re- vegetated area. Lafarge or its successors will be
responsible for reclaiming the site in coordination with the landowner, according to the
information from the Division of Reclamation Mining and Safety ( "DRMS ") permit. Lafarge has a
bond with the DRMS for $446,143 in the unlikely event of abandonment of the mine. The
attached Table 2 shows the projected delivery schedule for the increased lease and indicates
that the amended contract combined with the other replacement sources, are sufficient to
replace all depletions from the Gypsum Ranch Pit.
Note: According to Table 1 on page 19 of the decree entered in Case No. 2002CW211,
the historical consumptive use credit from 15 acres of dry-up under the C M Stremme and
Gates Ditch is 30.6 acre -feet per year. The 15 acres of dry-up produces a consumptive use
credit that exceeds the estimated depletions for the months of May through September. The
excess credits total 6.96 acre -feet for this period. According to the water balance table provided
for this SWSP (attached Table 2), these excess consumptive use credits will now be utilized to
replace the additional depletions approved under this SWSP. Approval by this SWSP to use
these excess consumptive use credits is limited to replacing depletions resulting from the gravel
pit mining operation at the Gypsum Ranch Pit. Any request to utilize these excess credits at a
different location, or for a different purpose may require a subsequent change of water right for
the C M Stremme and Gates Ditch and may require a re- quantification of the historical
consumptive use credits.
