Jared Dains
South Platte Combined Replacement Plan
March 21, 2011
Page 5
In accordance with approach no. 4, you have provided an affidavit dated January 25,
2011, that dedicates the 12.5 shares of the Whitney Ditch Company and 96 shares of the
Fulton Irrigating Ditch Company as replacement water solely for this SWSP for as long as
there are depletions at these gravel pit sites or until such time as another replacement
source is obtained. A copy of the affidavit is attached to this letter. For the purposes of this
SWSP, this affidavit will be accepted for the dedication of the shares; however, if the State
Engineer determines that a different affidavit or dedication process is necessary to assure
proper dedication of the shares, additional information may be required prior to future
SWSP approvals.
Also, in accordance with approach nos. 1 and 3, you have indicated that a bond has
been obtained for $1,579,400 for the Brighton Pit, $3,617,200 for the Watenberg Pit, and
$1,483,800 for the Distel Pit that can cover the cost of lining or backfilling these sites to
prevent the exposure of ground water.
Currently Aggregate is dewatering at the Tull Pit, Hazeltine Pit, Brighton Pit, W.W. Farms
Pit, and Distel Pit. All of the dewatering water is returned to the river, either directly or via a
drainage channel. All dewatered water must be delivered to the river without consumption. Platte
Valley Pit, F-Street Pit, Tucson Pit and East 8t' Street Pit have ceased dewatering.
Depletions
The depletions resulting from evaporation, water lost in product, dust control and concrete
batching are shown in Table 4 below:
