replacement water must be appurtenant to this site until a plan for augmentation is obtained. All
replacement water must be concurrent with depletions in quantity, timing, and location.
10. The Applicant has proposed to use for augmentation, water available from any other source
legally available for augmentation and which can be provided in the amount, at the time, and at
the location required to replace out of priority depletions from the gravel pit sites included in
this SWSP. Additional sources of replacement water in this SWSP may only be used if the
Applicant complies with the attached Division One Administration Protocol "Use of Replacement
Sources Not Specifically Identified in an SWSP or Augmentation Plan".
11. 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 submitted to the
division engineer and the water commissioner.
12. Conveyance loss for delivery of augmentation water to the South Platte River, Saint Vrain Creek
and the Cache La Poudre River is subject to assessment and modification as determined by the
division engineer.
13. 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.
14. All diversions shall be measured in a manner acceptable to the Division Engineer. The Applicant
shall install and maintain such measuring devices as required by the Division Engineer for
operation of this SWSP. In addition, 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 to the division
engineer in Greeley ([e-mail]) and the water commissioners (Brent Schantz at
[e-mail], Shera Sumerford at [e-mail] and Mark Simpson
at [e-mail]) within 30 calendar days of the end of the month for which the
accounting is being made. Submitted accounting shall conform to the Administration Protocol -
Augmentation Plan Accounting.
15. If reclamation of the mines at the gravel pit sites included in this SWSP 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 years prior to the completion of
mining to include, but not be limited to, long-term evaporation losses. 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 the Carbon Valley Pit, and Firestone Pit will produce delayed depletions to the
stream system. As long as the pits are continuously dewatered, the water returned to the stream
system should be adequate to offset the depletions. However, once dewatering at the sites
cease, the delayed depletions must be addressed. A plan that specifies how the post pumping
