TABLE D — FINAL RECLAMATION SUMMARY
Conditions of Approval
I hereby approve the proposed substitute water supply plan in accordance with Section § 37 -90-
137(11), C.R.S. subject to the following conditions:
1. This plan is approved with an effective date of January 1, 2013 and shall be valid through March 31,
2013 unless otherwise revoked or modified. The expiration date will be extended to December 31,
2013 if the Applicant submits the signed LCRC lease by March 31, 2013. 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 per pit) for each gravel pit no later than
February 15, 2013 (or November 15, 2013 if plan is extended)..
2. A well permit is required for the current use and exposed ground water surface at each site in
accordance with § 37 -90- 137(2) and (11), C.R.S, and have been obtained as shown on Table A.
Should a site no longer have a valid well permit for any reason, that site will be automatically
dropped from this combined SWSP.
3. The total area of pond surface exposed for each of the pits shall not exceed those values listed in
Table A of this approval. Should the total surface area exposed exceed those amounts, an
amendment request shall be promptly filed with this office.
4. The total amount of ground water to be appropriated from each of the pits shall not exceed the
values listed in Table B of this approval.
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. Any future additional historical consumptive use credit given (e.g.,
agricultural water transfer) for this site must consider all previous credits given.
6. All pumping for dust control shall be measured in a manner acceptable to the division engineer.
7. 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.
8. Applicant shall replace the net evaporative depletions from the exposed ground water surface
area that may occur during the assumed ice covered period (December through February) for any
time that the exposed ground water in the pit is not completely covered by ice.
