GSL Sand Et Gravel Substitute Water Supply Plan Page 5 of 5
October 19, 2021
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 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 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.
Should you have any questions, please contact Wenli Dickinson of this office or Dean Santistevan of
our Division office in Greeley at [phone].
Sincerely,
