We have received your letter of March 2, 2005, requesting renewal and amendment of the
above referenced substitute water supply plan to cover depletions caused by an existing gravel
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 May 27, 1992 and was last renewed
on January 10, 2001.
The Distel pit is comprised of four parcels know as the Peschel Parcel (owned by the City
of Boulder and the City of Longmont), the Sherwood Parcel (owned by the City of Longmont and
Donald Sherwood), the Distel Parcel (owned by Aggregate Industries) and the Landfill Parcel
(owned by the City of Longmont).
The total exposed pond area is 67.2 acres. Consumptive use of water at the property
consists of 172.7 acre-feet of evaporation from the 67.2 acres of exposed pond area, 15.83 acre-
feet of water lost in product (4% moisture of 537,826 tons of raw material), and 1.98 acre-feet for
dust control (Total 190.35 acre-feet).
The sources of replacement water area 100% interest in the Coffin & Davis Ditch, 19.6
shares in the Leggett-Owens Reservoir and fully consumable water leased from the City of
Westminster. Replacements during the historic irrigation season will be provided by the 100%
interest in the Coffin & Davis Ditch, which yields 328.5 acre-feet of consumptive use credits,
based on a ditch loss of 10%, farm efficiency of 55% and return flows of 50% surtace and 50%
subsurface. The conditional lease with the City of Westminster will provide 2.0 cfs of water every
day from November 10 to March 20. The remaining winter depletions will be replaced using the
19.6 shares in the Leggett-Owens Reservoir, which have an annual consumptive use credit of 33
acre-feet, based on a 55% efficiency.

To provide the security of a permanent, renewable source of replacement water which
could be used for replacement should the applicant cease mining, abandon the gravel mining
operation, and allow the pit to fill, a 52.5% interest in the Coffin & Davis is hereby dedicated to
