reclamation, replacement of lagged depletions shall continue until there is no longer an effect
on stream flow. Granting of this plan does not imply approval by this office of any such court
application(s).
13. 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. 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.
14. This substitute water supply plan may be revoked or modified at any time should it be
determined that injury to other water rights has or will occur as a result of this plan.
15. 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.
16. In accordance with amendments to Section §25-8-202-(7), C.R.S. and Senate Bill 89-181
Rules and Regulations adopted on February 4, 1992, the State Engineer shall determine if this
substitute water supply plan is of a quality to meet requirements of use to which the senior
appropriation receiving the substitute supply has normally been put. As such, water quality
data or analyses may be requested at any time to determine if the requirement of use of the
senior appropriator is met.
17. The dry year analysis required by this office for a permanent plan for augmentation may vary
from the analysis approved in this substitute water supply plan. This substitute water supply
plan shall have no precedential or evidentiary force and does not constitute an admission or
statement of position in any other proceeding. This plan shall not be concurrent with any
findings of fact or conclusions of law contained herein, or with the engineering methodologies
used by the applicant.
