Overland Ponds Site, M-02-081, and the North Taft Hill Expansion Site, M-O1-051
Deaz Ms. Comaniciu:
On behalf of Lafazge West, Inc.; Applegate Group, Inc. requests a renewal of the combined substitute
water supply plan (SWSP) for the Home Office Pit, M-77-439, Overland Ponds Site, M-02-081, and
the North Taft Hill Expansion Site; M-O1-051. These three sites are located adjacent to one another
and. are being submitted as a combined substitute water supply plan. The State Engineer's Office
(SEO) most recently granted an approval in a letter dated December 2, 2004. Enclosed please fmd e
check (No. 27788) for $771.00 made out to the Division of Water Resources for the renewal of this
plan.
The only water use at the Overland Ponds and North Taft Hill Expansion Sites will be evaporation
from exposed groundwater. The North Taft Hill Expansion Site is currently inactive. Lafarge will
convey the mined material from the Overland Ponds Site to the existing facilities at the Home Office
Pit for processing throughout the yeaz. Water use at the Home Office Pit will continue to include
evaporation, water retained in mined product and dust control.
The combined plan will continue to use the recharge of the historic consumptive use credit from 5.75
Taylor and Gill Ditch shares to make replacements and a lease from the Tri-Districts wiil also make
replacements. This combination of sources will replace all depletions in the combined SWSP during
Water Year 2007.
UPDATED CONSUMPTIVE USE
A summary showing the calculated consumptive use for each of the three mining sites is included in
Appendix A. Each summary reflects information from previous submittals.
