December 3, 2019
Page 3 of 5
1. This SWSP shall be valid for the period of January 1, 2020 through December 31, 2020, unless
otherwise revoked or superseded by decree.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 by November 1, 2020. If a renewal request is received after the
expiration date of this plan, it will be considered a request for a new SWSP and the $1,593
filing fee will apply.
2. Well Permit 74792-F has been issued for this pit, and this permit remains valid. The permit
covers up to 111.14 acres of exposed surface area, dewatering activities, and annual water uses
of 6.2 acre-feet for dust control, 22.1 acre-feet of water lost in mined product (750,000
tons/yr), 7.4 acre-feet for concrete production, and 0.4 acre-feet of asphalt production. Actual
depletions cannot exceed these amounts and are limited to those uses specifically approved
through this SWSP.
3. The total exposed ground water surface area at the NCCI Pit #1 must not exceed 5.96 acres (in
the dewatering trenches and ponds) during the approval period of this SWSP resulting in an annual
evaporative loss of 17.5 acre-feet.
4. Total consumption at the NCCI Pit #1 Pit must not exceed the aforementioned amounts unless
an amendment is made to this plan.
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. 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 at DivlAccountingCstate.co.us, to District 2 Water Commissioner at
Jorge.Vida L state.co.us, and to the River Operations Et Compact Coordinator at
Brent.SchantzCstate.co.us on a monthly basis. Submitted accounting shall conform to the
Administration Protocol "Augmentation Plan Accounting, Division One - South Platter River"
(attached).
In addition, the applicant shall verify that entities making replacement for this SWSP are
including that use on their monthly accounting submitted to this office. For the purposes of this
SWSP that entity is the City of Thornton (WDID 0202611).
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.
8. Conveyance loss for delivery of augmentation water is subject to assessment and modification
as determined by the division engineer. Currently 0.5% per mile conveyance loss is being
accounted for in the SWSP; this is subject to change depending upon current conditions.
9. All releases of replacement water must be sufficient to cover all out of priority depletions and
be made under the direction and/or approval of the water commissioner. The replacement may
be aggregated to maximize beneficial use. The water commissioner and/or division engineer
shall determine the rate and timing of an aggregated release.
10. The Division Engineer, or his designated representative, will administer all such water
transported in the South Platte River or its tributaries under this SWSP, including water for
replacement of depletions, past intervening headgates to ensure that such water is not
intercepted or otherwise diminished in quantity by diversion, use or other interference by
intervening water rights and to assure that such water remains available and suitable for
