at least 48 hours prior to making replacement deliveries at a location other than the Hite
Treatment Facility.

The Hite Treatment Facility is located approximately 10.62 miles upstream of the Spear Mining Pit.
The delivery schedule includes a transit loss of 0.5% per mile (5.31 % for 10.62 miles) during the
months of April through October and 0.25% per mile (2.655% for 10.62 miles) during the months of
November through March. Conveyance loss for delivery of augmentation water to the South Platte
River is subject to assessment and modification as determined by the division engineer. Any
changes to the assessed conveyance loss will be communicated to the Division One Call List via
email.

Conditions of Approval
I hereby approve this substitute water supply plan, in accordance with Section 37-90-137(11),
C.R.S., subject to the following conditions:
1. This plan shall be valid for the period of June 28, 2017 through December 31, 2018, unless
otherwise revoked or superseded by a decree. If this plan will not be made absolute by a
water court action by the plan’s expiration date, a renewal request must be submitted to this
office with the statutory fee of $257 no later than November 15, 2018.
2. Well permit no. 75688-F was obtained for the current use and exposed pond surface area of
the gravel pit in accordance with §37-90-137(2) and (11), C.R.S.
3. The total surface area of the groundwater exposed at the Speer Pit must not exceed the
values shown on Table AI.1 on a monthly basis. Should backfilling occur at a rate less than
projected this SWSP will become invalid and an amendment to this plan will be required.
4. The annual amount of water used for dust control at the Speer Pit shall not exceed 0.33
acre-feet. All pumping for dust control shall be measured in a manner acceptable to the
division engineer.
5. Total consumption at the Speer Pit must not exceed these aforementioned amounts unless
an amendment is made to this plan.
6. Approval of this plan is for the purposes as stated herein. This office must first approve any
additional uses for which the water may be used.
7. All releases of replacement water must be sufficient to cover all out-of-priority depletions
in time, place, and amount and must be made under the direction and/or the approval of
the water commissioner. The release of replacement water may be aggregated to maximize
beneficial use. The water commissioner and/or the division engineer shall determine the
rate and timing of an aggregated release.
8. The replacement water that is the subject of this plan cannot be sold or leased to any other
entity. As a condition of subsequent renewals of this substitute water supply plan, the
replacement water must be appurtenant to this site until a plan for augmentation is
obtained. A copy of this approval letter should be recorded with the County Clerk and
Recorder. All replacement water must be concurrent with depletions in quantity, timing,
and locations.
9. Adequate accounting of depletions and replacement must be provided to the division
engineer in Greeley ([e-mail]) and the water commissioner (Jorge Vidal
at [e-mail] and [e-mail]) on a monthly basis. All
