State Engineer
This letter is in response to your application of November 6, 2002 requesting a substitute
water supply plan for a gravel pit to be operated. by the Hall-Irwin Corporation, Inc., in accordance
with §37-90-137(11) C.R.S. The Applicants shall be responsible for compliance with this plan, but
the State Engineer's Office may also pursue the landowner, for eventual compliance. The
required. fee of $1,343 for the substitute water supply plan has been paid.
The anticipated net depletion for this plan is 62.03 acre-feet per year for up to 4.2 acres of
water surface exposed. after December 31,.1980. According to the information submitted, no
water surface was exposed within the reclamation permit boundary prior to January 1, 1981.
You have provided a monthly. breakdown. of the. maximum annual depletions totaling
12.1 acre-feet of evaporative loss from a maximum of 4.2 acres of exposed groundwater, 3.31
acre-feet of water used and consumed for dust control,. 24.55 acre-feet of water used in
concrete batching due to 160,000 cubic yards of concrete production, and. 22.06 acre-feet of
water lost with the 750,000. tons. of mined product. .
The water. used in the batch plant and used for on-site dust suppression. will be
produced from a new alluvial well... Since the water consumed by dust suppression and
concrete batching is considered 100 percent consumptive fhe total. pumping from the well will
be limited. to 27.86 acre-feet annually.
This plan anticipates dry mining of the Bemhardt Pit. The anticipated 4,2 acres of
exposed groundwater consists of 0.2 acres of dewatering trenches and. a 4-acre silt pond located
more than f 00 feet from the. Big Thompson River... To provide the security of a permanent,
renewable source of replacement water,. 3.5 shares of Big Thompson & Platte River Ditch are
hereby dedicated. to this plan and made appurtenant to the tract of land. where the gravel pit will
be located,. until. a permanent augmentation plan for the gravel. pit has been adjudicated. These
shares were found to be adequate to cover the depletions from evaporation. that would occur if
the dewatering. process was stopped and. the 20-acre pond was allowed to fill. A copy of this
approval letter and a copy of the stock certificate shalt be recorded with. the Weid County Clerk
and Recorder's. Office.. During the term of this substitute water supply plan the 3.5 shares of
Big. Thompson & Platte River Ditch may continue to be used for irrigation as long. as the
depletions caused. by the pit are covered by other approved sources.
