20317R, 1408R, 2819F, 1657RR, 2820F, 20583R, 12800R and 19944RF in accordance
with §37-90-137(2). The provisions of §37-90-137(2) 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 the 600 foot spacing,
or any other legitimate reason, approval of this amendment will be canceled.
3. The total area of exposed pond surface shall not exceed 24 acres and total consumptive
use of the mining operation shall not exceed 146.3 acre-feet of which 70 acre-feet is due
to evaporative losses, 2 acre-feet is due to dust suppression, 58.9 acre-feet is due to
water remove in product (4% moisture of 2,000,000 tons of raw material) and 15.5 acre-
feet is due to concrete batching (150,000 cubic yards). Should the total consumption at
the pit exceed these amounts prior to the expiration date of this plan, an amendment
needs to be filed with this office.
4. Water discharged from the pit and utilized to offset depletions caused by the pit operation
cannot be banked or credited to offset lagged depletions in subsequent period of time. All
discharges will be available to offset depletions only during the time when depletions are
actually occurring.
5. Approval of this plan is for the purposes as stated herein. Any additional uses of this
water must first be approved by this office.
6. All pumping for product washing, concrete batching, dust control and dewatering shall be
measured in a manner acceptable to the Division Engineer and Water Commissioner.
7. The Water Commissioner responsible for the administration of this plan is Mr. Robert
Stahl, 9378 WCR 25, Fort Lupton, CO 80621, phone no. [phone]. The applicant
shall maintain daily records of all diversions, replacements, and the amount of water used
for each particular purpose. The applicant shall provide a report of these records to the'
division engineer and the water commissioner on a monthly basis on a form approved by
them. The accounting must be submitted within thirty (30) calendar days of the end of the
month for which the accounting is being made.
In addition, the applicant shall submit a report from the City of Aurora ("Aurora"). The report
shall include an accounting of all replacement water controlled by Aurora, showing the total
volume of water under its control and the amount committed to each of the recipients of the
water.
8. The name, address and phone number of a contact person who will be responsible for the
operation and accounting of this plan must be provided on the accounting forms to the
Division Engineer and Water Commissioner.
9. The approval of this substitute water supply plan does not relieve the Applicant and/or the
landowner of the requirement to obtain a Water Court decree approving a permanent plan
for augmentation or mitigation to ensure the permanent replacement of all depletions,
including long-term evaporation losses and lagged depletions after gravel mining
operations have ceased. If reclamation of the mine site will produce a permanent water
surface exposing groundwater to evaporation, an application for a plan for augmentation
must be filed with the Division 1 Water Court at least three (3) years prior to the
completion of mining, to include, but not be limited to, long-term evaporation losses and
