Bucklen Pit SWSP Page 7 of 9
October 28, 2014
11. The water attributable to the six (6) shares of the Greeley Irrigation Company must continue
to be diverted in priority at the ditch and then measured back to the Cache La Poudre River in
the vicinity of the Bucklen Pit. Adequate measuring devices acceptable to the water
commissioner must be installed.
12. Conveyance loss for delivery of augmentation water is subject to assessment and modification
as determined by the water commissioner or division engineer.
13. Adequate accounting of depletions and replacements must be provided to the division
engineer in Greeley ([e-mail]) and the water commissioner (Mark Simpson
at [e-mail]) on a monthly basis or other interval acceptable to both of
them. Submitted accounting shall conform to the attached Division One Administration
Protocol "Augmentation Plan Accounting, Division One - South Platte Basin".
In addition, it is the applicant's responsibility to verify that the entities making replacements
are identifying this use on their accounting submitted to our office. For the period of this
plan, that entity is City of Aurora.
14. The name, address and phone number of the 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.
15. The approval of this SWSP does not relieve the Applicant and/or 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 lagged depletions. if a lined pond results after reclamation,
replacement of lagged depletions shall continue until there is no longer an effect on stream
flow.
16. Dewatering at this site will produce delayed depletions to the stream system. As long as the
pit is continuously dewatered, the water returned to the stream system should be adequate to
offset the depletions attributable to the dewatering operation. The operator shall equip the
dewatering operations with a totalizing flow meter and report monthly meter readings which
will be used to determine the post-pumping depletions when dewatering ceases. Once
dewatering at the site ceases, the delayed depletions must be addressed. Accordingly,
dewatering is required to continue during the term of this approval. At least three years prior
to completion of dewatering, a plan must be submitted that specifies how the post pumping
dewatering depletions (including refilling of the pit) will be replaced, in time, place and
amount.
17. If dewatering of the site is discontinued, the pit would fill creating additional depletions to
the stream system due to increased evaporation. To assure that depletions from ground water
evaporation do not occur in the unforeseen event, or events, that would lead to the
abandonment of the pit, the Applicant has dedicated five (5) Greeley Irrigation Company
shares as replacement water solely to this SWSP for as long as there are depletions at this
gravel pit site or until such time as another replacement source is obtained. A copy of the
