Ready Mix Concrete Substitute Water Supply Plan Page 9 of 9
October 26, 2022
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.
21. 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, all excavation of the
product from below the water table, and all other use of water at the pit, must cease
immediately.
22. 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 the
substitute supply 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.
23. 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 SWSP. This decision shall not
bind the state engineer to act in a similar manner in any other applications involving other SWSPs
or in any proposed renewal of this SWSP, 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.
