We have reviewed your letter of November 30, 2004 requesting renewal of the above
referenced substitute watersupply plan foran existing sand and gravel 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 August 8, 2000 and it was most recently approved in a letter dated June 19, 2002.
The anticipated net depletion for this plan is 45.5 acre-feet peryear. The total surface area of
the groundwater exposed at the site equals 35.8 acres. According to the information submitted, 29.7
acres of ground water was exposed after December 31, .1980 and 6.1 acres of surface was exposed
within the reclamation permit boundary prior to January 1, 1981. The Feit Pit is being dewatered
from April though October to allow dry mining thus reducing the exposed surface area to 9.6 acres.
The location of the dewatering pumps is within 100 feet from the Cache La Poudre River.
Accordingly, the evaporative depletions from April through October were calculated to an exposed
surface area of 9.6 acres and were determined to be 23.1 acre-feet. The pit is allowed to fill from
November through March. The evaporative depletions from November through March were
determined to be 15.4 acre-feet.
You have provided a monthly breakdown of the annual depletions totaling 38.5 acre-feet of
evaporative loss, 0.8 acre-feet of water used and consumed for dust control, 2.9 acre-feet of water
lost with 100,000 tons of mined product, 3.1 acre-feet of water used in concrete production, and
0.11 acre-feet of water used for drinking and sanitary purposes. The water used for drinking and
sanitary purposes is to be withdrawn from, well permit no. 57724-F. No phreatophyte credit has
been applied to this plan.
The sources of replacement water to be used for this plan are 21.4 acre-feet of historic net
stream depletions from the dry-up of lands historically irrigated with applicant's 2.8125 shares of
Greeley Canal #3, and 25.4 acre-feet of reusable municipal return flows leased from the City of
Greeley at its wastewater treatment plant. A lease agreement with the City of Greeley was
submitted to the State Engineer's Office on December 15, 2004. The lease provides 25.4 acre-feet
of replacement water from November 2004 through October 2005.
