W e have reviewed your letter of March 21, 2005, requesting renewal of the above referenced substitute
water supply plan to cover depletions caused by an epsting mining operation. The required fee of $217.00 for
the renewal of this substitute supply plan has been submitted. The original supply plan was approved on March
25, 1994 and it was most recently renewed on March 25, 2004.
The anticipated net depletion forthis plan is 120.2 acre-feet peryear, which includes evaporation from
up to 38.9 acres of ground water exposed after December 31,1980. According to the information submitted,
6 acres of ground water were exposed within the reclamation permit boundary prior to January 1,1981. No
dewatering is provided or sought under this plan.
You have provided a monthly breakdown of the annual depletions totaling 113.8 acre-feet of
evaporative loss, 2 acre-feet of water used and consumed for dust control, 4.4 acre-feet ofwater lostwith the
mined product. No phreatophyte credit has been applied to this plan. The Geisert PR is located less than 100
feetfrom the Cache La Poudre Riverand instantaneous depletions to the riversystem are assumed. Permit no.
5042rF was issued for the gravel pit pond (Geisert Pit) on August 19, 1998 and this permit remains valid.

effluent from the City of Greeley. Weld County has a perpetual lease with the Ciiy of Greeley for the right to
use up to 300 acre-feet per year of the Greele~s reusable effluent. A copy of the lease agreement with the
City of Greeley for 1202 acre-feet of fully consumable effluent from Greeley's wastewater treatment plant to
be used at the Geisert Pitwas submitted to this office wrth this renewal request The monthly depletions and
replacement requirements are found on the attached Table I.
