Greeley Pit SWSP April 6, 2020
Plan ID 2965 Page 7 of 10
shares are expected to provide approximately 87.64 acre-feet of consumptive use credit per year
(10.31 acre-feet per share x 8.5 shares). Although this amount exceeds the depletions associated
with the current 71.8 acres of exposed groundwater at the site, additional replacement water will
need to be obtained to replace depletions from the 95 acres of exposed groundwater proposed
to remain at the site after final reclamation. According to information in the DRMS files, if the
Applicant is not able to purchase the required water shares, the DRMS will calculate the required
financial warranty to backfill the exposed groundwater areas not covered by the dedicated shares.
SWSP Conditions of Approval
I hereby approve the proposed 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 April 1, 2020 through March 31, 2021 (or March 31,
20221 if extended) unless otherwise revoked or superseded by decree. This SWSP will only be
extended for the period of April 1, 2021 through March 31, 2022 if a copy of the executed
lease for replacement water described herein is provided to this office on or before March
311 2021. 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 prior to the expiration date but no later than February 1, 2021 (February 1, 2022, if
extended). If a renewal request is received after the expiration date of this plan, it may be
considered a request for a new SWSP in which case the $1,593 filing fee will apply.
2. Well permit no. 74638-F has been obtained for the current use and exposed pond surface area
of the gravel pit in accordance with sections 37-90-137(2) and (11), C.R.S.
3. The total surface area of the groundwater exposed at the Greeley Pit after December 31,
1980 must not exceed 31.6 acres, which results in a maximum annual evaporative loss of
92.64 acre-feet (87.19 acre-feet assuming ice cover during the months of December and
January).
4. The annual amount of water used at the Greeley Pit for dust control shall not exceed 1.00
acre-feet.
5. Total consumption at the Greeley 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. Any additional uses of the water
will be allowed only if a new SWSP is approved for those additional uses.
7. The Applicant shall replace the net evaporative depletions from the exposed groundwater
surface area that may occur during the assumed ice covered period (December and January)
for any time that the exposed groundwater in the pit is not completely covered by ice.
8. The replacement water that is the subject of this plan cannot be sold or leased to any other
entity, unless prior written approval is granted by the water commissioner and/or the division
engineer. 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.
9. The Applicant has proposed to use for augmentation, water available from any other source
legally available for augmentation and which can be provided in the amount, at the time, and
at the location required to replace out of priority depletions from the Greeley Pit. Additional
