CONDITIONS FOR APPROVAL
® The proposed operation will consume ground water by: ® evaporation, ® dust control,
reclamation, ® water removed in the mined product, ? processing, ? other:
Prior to initiation of these uses of ground water, the applicant will need to obtain either a gravel pit
or other type of well permit, as applicable. However, prior to obtaining a permit, an approved
substitute water supply plan or decreed plan for augmentation is required.
® Prior to approving a well permit, the applicant must conduct a field inspection of the site and
document the locations of all wells within 600 feet of the permit area. The applicant must then
obtain a waiver of objection from all well owners with wells within 600 feet of the permit area or
request a hearing before the State Engineer.
® If stormwater is contained on-site, it must infiltrate into the ground or be released to the natural
stream system within 72 hours, or all work must cease until a substitute water supply plan, or
augmentation plan approved by water court, is obtained.
COMMENTS: The applicant has estimated annual water consumption at the site to be 7 acre-feet for
evaporative losses, 22.1 acre-feet for water retained in the mined product, and 24.1 acre-feet for dust
control. The total estimated consumptive use for the site is 28.5 acre-feet per year during mining
operations. After mining, the site will be reclaimed with 8 unlined ponds totaling 60 acres. The
consumptive use associated with these ponds is estimated to be 177.2 acre-feet per year.
The applicant has indicated plans to obtain a substitute water supply plan prior to the start of mining, and a
plan for augmentation three years prior to the completion of mining. No ground water shall be exposed by
this operation until such a substitute water supply plan has been approved by the State Engineer or plan
for augmentation has been approved by the water court.
Please note that the creation of wetlands causes depletions to the stream system through evaporation
from the water surface and the consumptive use of water by plant life. If wetlands mitigation exceeds a
ratio of 1:1, the stream system must be compensated for these depletions in time, place and amount
through a court approved augmentation plan or a State Engineer approved substitute supply plan.
The applicant may contact the State Engineer's Office with any questions.
