4. Approval of this plan is for the purposes as stated herein. Any additional uses of this water
must first be approved by this office.
5. The Water Commissioner responsible for the administration of this plan is Mr. Bob
Carlson, Post Office Box 380, Erie, Colorado 80516, 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 thirty (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 the City of Louisville. The report shall
include an accounting of all replacement water controlled by the City of Louisville, showing the
total volume of water under its control and the amount committed to each of the recipients of
the water.
6. 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.
7. 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 wilt 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 from
mining and dewatering shall continue until there is no longer an effect on stream flow.
8. 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.
9. Conveyance loss for delivery of augmentation water is subject to assessment and
modification as determined by the division engineer.
10. The applicant plans to discharge the water obtained from the dewatering process to
recharge trenches. If at any time it is determined that consumption is occurring due
to evaporation (in excess of the evaporation currently covered under this plan) or
irrigation of phreatophytes, the applicant must discharge the water directly back to
the stream or show that the depletions are being replaced.
71. The recharge operation should be operated in such a manner as to not cause property
damage. Any property damage that results from the recharge project is solely the
applicant's responsibility.
12. If the water obtained from dewatering is discharged directly back to the river, delayed
depletions to the stream system will result. 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.
