NCCI Pit #1 Substitute Water Supply Plan - Amendment Page 4 of 4
May 9, 2024
permanent replacement of all depletions, including long-term evaporation losses and lagged depletions
after gravel mining operations have ceased. If reclamation of the mine site will produce a permanent
water surface exposing groundwater to evaporation, an application for a plan for augmentation must
be filed with the Division 1 Water Court at least three (3) years prior to the completion of mining to
include, but not be limited to, long-term evaporation losses and lagged depletions. If a lined pond
results after reclamation, replacement of lagged depletions shall continue until there is no longer an
effect on stream flow.
14. The State Engineer may revoke this SWSP or add additional restrictions to its operation if at any time the
State Engineer determines that injury to other vested water rights has occurred or will occur as a result
of the operation of this SWSP. Should this SWSP expire without renewal or be revoked prior to
adjudication of a permanent plan for augmentation, the Applicant must continue to provide
replacement water for all out-of-priority depletions resulting from the operation of this SWSP, including
those lagged depletions that occur to the stream after the expiration date of this SWSP.
15. To assure that depletions from groundwater evaporation do not occur in the unforeseen event, or
events, that would lead to the abandonment of the pit, a bond through DRMS for $486,745 for lining of
the pit has been obtained. Therefore, in case of abandonment the bond can finance the completion of
the lining of the pit or the backfilling, thus preventing depletions to the stream system.
16. In accordance with amendments to section 25-8-202-(7), C.R.S. and "Senate Bill 89-181 Rules and
Regulations" adopted on February 4, 1992, the State Engineer shall determine if this substitute water
supply plan is of a quality to meet requirements of use to which the senior appropriation receiving the
substitute supply has normally been put. As such, water quality data or analyses may be requested at
any time to determine if the requirement of use of the senior appropriator is met.
17. The decision of the State Engineer shall have no precedential or evidentiary force, shall not create any
presumptions, shift the burden of proof, or serve as a defense in any water court case or any other legal
action that may be initiated concerning the substitute water supply plan. This decision shall not bind
the State Engineer to act in a similar manner in any other applications involving other plans or in any
proposed renewal of this plan, and shall not imply concurrence with any findings of fact or conclusions
of law contained herein, or with the engineering methodologies used by the Applicant.
