3. Approval of this plan is for the purposes as stated herein. Total consumption at the pit must
not exceed the amounts identified above unless this office has first approved an amendment to
this plan.
4. The replacement water that is the subject of this plan cannot be sold or leased to any other
entity. As a condition of subsequent renewals of this substitute water supply plan, the
replacement water must be appurtenant to this site until a plan for augmentation is obtained, or
the pit has been lined. A copy of this approval letter should be recorded with the County Clerk
and Recorder. All replacement water must be concurrent with depletions in quantity, timing,
and locations.
5. The name, address, and phone number of a 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.
6. The Water Commissioner responsible for the administration of this plan is Mr. Robert Stahl,
9378 WCR 25, Fort Lupton, CO 80621, 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 commissioner on a monthly basis on a form approved by them. The
accounting must be submitted within 30 calendar days of the end of the month for which the
accounting is being made.
In addition, the applicant shall submit a report from each entity making replacements; for this
plan, those entities are SACWSD and the City of Aurora. The report shall include an
accounting of all wastewater plant water efFluent controlled by each entity, showing the total
volume of water under its control at the various wastewater treatment plants, and the amount
committed to each of the recipients of the water.
7. This substitute water supply plan may be revoked or modified at any time should it be
determined that injury to other vested water rights has or will occur as a result of this plan.
8. Should this substitute water supply plan expire without renewal or be revoked prior to
adjudication of a permanent plan for augmentation, all excavation of product from below the
water table and all other use of water at the pit must cease immediately.
9. Dewatering at this site wi{I 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. However, once dewatering at the site ceases the delayed depletions
must be addressed. At least three years prior to completion of dewatering, a plan must be
submitted that specifies how the post pumping dewatering depletions will be replaced, in time,
place and amount.
10. The approval of this substitute water supply plan does not relieve the Applicant and/or the
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
