15. This substitute water supply plan may be revoked or modified at any time should it be
determined that injury to other vested water rights has or will occur as a result of this plan.
Should this substitute water supply plan expire without renewal or be revoked prior to
adjudication of a permanent plan for augmentation, all excavation of product from below the
ground water table and all other use of water at the pit must cease immediately.
16. In accordance with amendments to §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 whether the
substitute supply is of a quality to meet requirements of use to senior appropriators. As
such, water quality data or analysis may be requested at any time to determine if the water
quality is appropriate for downstream water users.
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 pending
water court case or any other legal action that may be initiated concerning this 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.
