period of this plan, that entity is the City of Aurora (WDID 0802593 - Aurora Reuse).
9. 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.
10. Conveyance loss for delivery of augmentation water to the South Platte River is subject to
assessment and modification as determined by the division engineer.
11. The Division Engineer, or his designated representative, will administer all such water
transported in the South Platte River or its tributaries under this SWSP, including water for
replacement of depletions, past intervening headgate to ensure that such water is not
intercepted or otherwise diminished in quantity by diversion, use or other interference by
intervening water rights and to assure that such water remains available and suitable for
Applicant's uses under this SWSP, except when any intervening headgate is diverting the
entire flow of ("sweeping") the river. In the event that delivery past headgate which sweep
the river requires the installation of a bypass structure or the use of an existing bypass
structure by agreement with a third-party, Applicant is responsible for either installation a
new bypass structure with a continuous recording measuring device(s) as approved by the
Water Commissioner or securing an agreement with a third-party to use an existing bypass
structure and providing such information and agreement to the Division Engineer.
12. 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, or lagged depletions only if a lined pond results after
reclamation, until there is no longer an effect on stream flow.
13. DRMS Permit No. M-2001-085 no longer requires a lined reservoir in the final reclamation
plan. The Applicant's proposed amendment to DRMS, changing the final reclamation plan
from water storage to an inert backfill operation, was approved. With the next SWSP renewal
request, the Applicant is required to continue to demonstrate they are in compliance with
their DRMS permit reclamation plan and the April 30, 2010 DRMS letter (attached).
14. The Applicant is required to maintain their DRMS permit and an adequate bond to cover their
reclamation plan until (1) there are no longer lagged depletions hitting the river, (2) a
suitable augmentation plan is obtained, or (3) another party assumes full augmentation
responsibilities. The Applicant has a current bond of $368,590 to account for backfilling the
pit. With all future SWSP renewal requests, the Applicant will be required to demonstrate
continuing compliance, or diligent pursuit of compliance, with the April 30, 2010 DRMS letter,
specifically in regard to the required financial warranty for the site.
15. 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.
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. In addition, lack
of timely accounting may prevent proper administration, which may lead to revocation or
modification of this plan.
16. In accordance with amendments to §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 whether the
