GSL Sand & Gravel Substitute Water Supply Plan  Page 3 of 5
April 5, 2021

The current financial warranty posted for the site is $368,590, which was set by DRMS after
approving an amendment request to change the reclamation plan from water storage to an inert
backfill operation on the property (to two feet above the water table). This action satisfied the
requirement that the Applicant diligently pursue compliance with their DRMS permit and the
requirements described in the April 30, 2010 letter DRMS sent to all gravel pit operators
(attached), specifically in regard to the required financial warranty at the site. With each
successive SWSP renewal request, the Applicant shall demonstrate continued diligence in this
effort, including maintaining satisfactory status in obtaining proper bonds through DRMS .

not decreed in water court by the SWSP expiration date, a renewal request must be submitted
to this office with the statutory fee of $257 no later than September 15, 2021. If a renewal
request is received after the expiration date of this plan, it will be considered a request
for a new SWSP and a filing fee of $1,593 will be required.

site in accordance with sections 37-90-137(2) and (11), C.R.S.
3.The total surface area of the groundwater exposed at the site must not exceed 2.10 acres
during the approval period of this SWSP, resulting in annual evaporative losses of 6.00
acre-feet.
4.This SWSP does not permit any water use for dust control, aggregate production or any other
purpose, other than evaporation.
5.Total consumption at the site must not exceed the aforementioned amounts unless an

beneficial use. The Water Commissioner and/or the Division Engineer shall determine the rate
and timing of an aggregated release.

Applicant shall install and maintain such measuring devices as required by the Division
