$11,750 through the DRMS. According to DRMS, the bond amount will be reevaluated to fully
cover the exposed groundwater once the SWSP and well permit are issued for the operation.
Conditions of Approval
I hereby approve the proposed SWSP in accordance with § 37-90-137(11), C.R.S. subject to
the following conditions:

1. This SWSP is approved with the effective date of August 18, 2017 and shall be valid through
March 31, 2018 unless revoked or superseded by a decree. This plan will be extended until March
31, 2019 if the lease for replacement water is renewed through March, 2019 and a copy of the
renewed lease and a revised version of Table 2 that extends through March 2019 is provided to this
office, the Division Office, and the water commissioner by the end of March 2018. Additional
SWSPs are required until a court decreed plan for augmentation is obtained for the proposed uses.
If this plan is 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 February 15, 2018 (or
February 15, 2019 if extended).
2. Approval of this SWSP is for the purposes stated herein: evaporation, water removed with mined
product, and the first fill at BA’s operation. A well permit must be issued for the gravel pit in
accordance with Section § 37-90-137(2) and (11), C.R.S. prior to the exposure or use of
groundwater. A well permit application has been submitted to this office (receipt no. 3680272) and
this application is pending evaluation. Until a gravel pit well permit is approved, consumptive use
and exposure of groundwater on this site is prohibited. The provisions of § 37-90-137(2), C.R.S.
prohibits the issuance of a permit for a well to be located within 600 feet of any existing well,
unless the State Engineer finds that circumstances so warrant after a hearing held in accordance
with the procedural rules in 2CCR402-5. This hearing may be waived if you are able to obtain
statements from the owners of all wells within 600 feet, verifying that they have no objection to
your use of the proposed well. Should a new well permit be denied for reasons of 600 foot
spacing, or any other legitimate reason, approval of this SWSP will be cancelled.
3. The total surface area of the groundwater exposed at the BA site must not exceed 3.45 acres,
which results in gross evaporation depletions of 14.1 acre-feet per year. In future SWSP requests,
the Applicant may elect to replace only the net evaporation of groundwater in order to reduce the
stream obligation.
4. The total product mined at the BA site shall not exceed 3,000 cubic yards, which results in 1.34
acre-feet of depletions due to water lost with the mined product and the first fill.
5. Total consumption at the BA site must not exceed these aforementioned amounts unless an
amendment is made to this SWSP.
6. The replacement water that is the subject of this SWSP cannot be sold or leased to any other
entity. All replacement water must be concurrent with depletions in quantity, timing, and
locations.
7. All diversions shall be measured in a manner acceptable to the division engineer. The Applicant
shall install and maintain such measuring devices as required by the division engineer for
operation of this SWSP. In addition, the applicant shall maintain daily records of mined
product, ground water exposed to evaporation, replacements, and the amount of water used for
each particular purpose. The applicant shall provide a report of these records to the division
engineer ([e-mail]) and the water commissioner ([e-mail])
on a monthly basis. The accounting must be submitted within 30 calendar days of the end of the
