obtained for the proposed uses by the SWSP expiration date, a renewal request must be
submitted to this office with the statutory fee of $257 no later than April 1, 2018.
2. Well permit no. 80245-F was obtained for the current use and exposed pond surface area of
the gravel pit in accordance with § 37-90-137(2) and (11), C.R.S.
3. The total surface area of the ground water exposed at the Parsons Mine site must not
exceed 14.02 acres, which results in an annual net evaporative loss of 34.87 acre-feet.
4. The annual amount of water used for dust control at the Parsons Mine site shall not exceed
23.71 acre-feet, and the total product mined at the Parsons Mine site shall not exceed
742,000 tons per year, of which not more than 329,450 tons shall be washed and the
remaining 412,550 tons shall not be washed, which results in 15.76 acre-feet of water lost
with the mined aggregate.
5. Total consumption at the Parsons Mine site must not exceed these aforementioned amounts
unless an amendment is made to this SWSP.
6. Approval of this SWSP is for the purposes as stated herein. This office must first approve
any additional uses for the water. Any future historical consumptive use credit given (e.g.,
agricultural water transfer) for this site must consider all previous credits given.
7. All releases of replacement water must be sufficient to cover all out-of-priority depletions
in time, place, and amount and must be made under the direction and/or the approval of
the water commissioner. The release of replacement water may be aggregated to maximize
beneficial use. The water commissioner and/or the division engineer shall determine the
rate and timing of an aggregated release.
8. The water attributable to the 12 shares of the Whitney Ditch that will be used for direct
replacements must continue to be diverted in-priority at the ditch then measured back to
the Cache la Poudre River in the vicinity of the Parsons Mine. Adequate measuring devices
acceptable to the water Commissioner must be installed.
9. All pumping for dust control shall be measured in a manner acceptable to the division
engineer.
10. Computation of evaporation under this plan was reduced during the ice covered period. You
have assumed the ice covered period to occur during the months of December and January.
However, for the purpose of this SWSP, the Applicant shall replace the net evaporation
depletions from the exposed ground water surface area that may occur during the assumed
ice covered period (the months of December and January) for any time that the exposed
water surfaces are not completely covered by ice.
11. The replacement water that is the subject of this SWSP cannot be sold or leased to any
other entity. As a condition of subsequent renewals of this SWSP, the replacement water
must be appurtenant to this site until a plan for augmentation is obtained.
12. 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.
13. The Applicant shall provide daily accounting (including, but not limited to diversions,
depletions, replacement sources, and river calls) on a monthly basis, or more frequent if
required by the water commissioner. The accounting must be emailed to the water
commissioner (Mark Simpson at [e-mail]) and
