. ~7CW373

Applicant shall dry up sufficient acreage to offset all depletions from the
development.

E. Wastewater treatment will b~ through a central collection system with treatment
at the New Castle wastewater treatment plant. In-house water use shall be
deemed to consume 5 percent of the water diverted for such use. Each irrigated
acre will consume 1.56 acre-feet of water. Based on 70 percent irrigation
efficiency, it is assumed that 2.26 acre-feet of water will be applied per acre.

F. The Applicant has currently dried up approximately 13 acres of land in order to
obtain credit to develop. After the development of 75 percent of the allowable
EQRs for this existing dry up of 13 acres, the Applicant shall check assumptions
in this Decree and readjust its accountirig to reflect actual water use by the
development. In so doing, Applicant, at a minimum, shall determine separately
the amount of water delivered in the most recent year to the Castle Valley P.U.D.
for in-house use and for outside use. It will be assumed that the total deliveries
to the Castle Valley P.U.D. during the months of November through February
represent in-house use. The average monthly deliveries for the months of
November through February will be subtracted from the total deliveries to the
P. U.D. for each of the remaining months to determine the amount of outside use.
A five percent (5 %) consumption ratio shall be applied to in-house use and a 70
percent consumption ratio applied to outside use to determine consumptive use on
a monthly basis. ' The monthly consumptive use so calculated will then be
compared to the monthly historic consumptive use credit available from the acres
dried up. The Applicant shall, using water use assumptions on the EQR table in
Exhibit D, recalculate the necesssary number of acres to be dried up to
correspond to actual water use. Should the Applicant discover that water use is
higher than originally assumed and, therefore, an insufficient numberof ~cres has
been dried up for the actual water use, adjustments to the number of acres dried
up shall be made. The ratio of EQRs-per acre dried up in Paragraph 7.D., as
well as ,to the table in Paragraph H.C., shall also be adjusted; Any such changes
shall control until the next periodic check is made pursuant to this paragraph.
The Applicant shall prepare a report reexamining such Calculations upon
development of 75 percent of the allowable EQRs under each 10+/- acre block
of dry up acreage. No change in water right application will be necessary, to
accomplish such change in accounting; however, the Applicant may not reduce
the pumber of acres to be dried up below that contained in the application. Each
, report prepared under this paragraph shall be fIled with the Division Engineer and
written notice of the fIling of such report given to the Objectors. A copy of the
report shall be provided to any Objector _ upon request. The Applicant's
requirements under this paragraph shall expire as contained in Paragraph 23, -
below.

G. Based upon the decreed rate of application and the actual historic use under the
water rights to be used for augmentatio~, 140 acres have been irrigated under the
Coryell Ditch water rights and 193 acres have been irrigated under the Red Rock
