letter and a copy of the stock certificate shall be recorded with the Weld County Clerk and
Recorder's Office. During the term of this substitute water supply plan the 2 shares of Kern
Reservoir may continue to be used for irrigation as long as the depletions caused by the pit are
covered by other approved sources.
A monthly breakdown of depletions and replacements is shown in the attached Table No.
4 that was submitted with your report.
Conditions of Approval
I approve the proposed substitute water supply plan in accordance with Section 37-90-
137(11), C.R.S., subject to the following conditions:
This SWSP shall be valid for the period of January 1, 2007 through December 31, 2007,
unless otherwise revoked, modified, or superceded by decree. If this plan will not be
made absolute by a water court action by the plan's expiration date, a renewal request
must be submitted to this office with the statutory fee (currently $257) by November 1,
2007.
2. Anew well permit must be obtained for the gravel pit in accordance with §37-90-137(2)
and (11), C.R.S. Any application will be evaluated subsequent to approval of this plan.
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 losses associated with this mining operation must not exceed a total of 57.48 acre-
feet for the duration of this permit approval. These losses include 30.89 acre-feet of
evaporation from the proposed exposure of 10.72 acres of groundwater after December
31, 1980, 11.77 acre-feet of water lost in product (4% moisture of 400,000 tons of raw
material), 3.31 acre-feet for on-site dust control and 11.51 acre-feet used in the
production of 75,000 tons of concrete. Should the consumptive use at the site exceed
57.48 acre- prior to the expiration date of this plan, an amendment will need to be filed
with this office.
4. Approval of this plan is for the purposes as stated herein. Any additional uses of this
water must first be approved by this office.
The Water Commissioners responsible for the administration of this plan are Mr. Robert
Stahl, 9378 WCR 25, Fort Lupton, CO 80621, phone no. [phone] and Mr. Fred
Renner, 418 West 12`" Street, Loveland, CO 80537, 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 commissioners 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.
