3. The annual volume of ground water used for dust control shall not exceed 6.0 acre-feet,
and the annual amount of product mined shall not exceed 500,000 tons, which results in
14.71 acre-feet of ground water lost with the mined aggregate. No additional use of water
is allowed unless an amendment to this plan is obtained.
4. The lagged depletions associated with this mining operation must not exceed 132.92 acre-feet
during the period February 1, 2015 — January 31, 2016 and 148.39 acre-feet during the
period February 1, 2016 — January 31, 2017. Documentation of pond size may be required
by the Division Engineer in the form of an aerial photo evaluation or survey by a
Professional Land Surveyor during the term of this plan.
5. All diversions, including dust suppression, must be measured in a manner acceptable to the
division engineer and in accordance with the "Amendments to Rules Governing the
Measurement of Tributary Ground Water Diversions Located in the Arkansas River Basin".
6. Well permit no. 61403-F was previously issued for the exposure of up to 40 acres of ground
water; however, a new well permit must be obtained for the proposed exposure of up to
42.1 acres of ground water under this plan. A permit application (receipt no. 3667398) has
been submitted and is pending further action by this office. The provisions of § 37-90-
137(2), C.R.S., prohibit 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 in accordance with the procedural rules in 2CCR402-5. The hearing will 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 may be
cancelled.
7. Approval of this plan is for the purposes as stated herein. Any additional uses of this water
must first be approved by this office. Any future additional historic consumptive use credit
given (e.g., agricultural water transfer) for this site must consider all previous credits given.
8. Dewatering at this site will produce delayed depletions to the stream system. As long as
the pit is continuously dewatered, the water returned to the stream system should be
adequate to offset the depletions. However, once dewatering at the site ceases, the
delayed depletions must be addressed. Accordingly, dewatering is required to continue
during the term of this plan. At least three years prior to completion of mining, a plan must
be submitted that species how the post pumping dewatering depletions (including refilling
of the pit with ground water) will be replaced in time, place and amount. The Applicant is
hereby notified that if dewatering ceases, then depletions to the stream as a result of
refilling of the pit must be addressed as outlined by Guideline 14 of the April 1, 2011
General Guidelines for Substitute Water Supply Plans for Sand and Gravel Pits.
9. Adequate accounting of depletions and replacements (in acre-feet) must be provided to the
Water Commissioner (Joshua. Kasoe[@state.co.us) and the Division Engineer
(Augmentation. Coordinator. CaD-state. co. us) on forms and at times acceptable to both of
them. The accounting form(s) shall be sufficient to demonstrate that the net effective
replacement equaled or exceeded the total depletion on a monthly basis. All replacement
water must be concurrent with depletions in quantity, timing and location, except that
releases aggregated at the discretion of the Division Engineer may occur in a later month
than the depletions. Said accounting must be received by the 10th of the month following
