7. Approval of this SWSP is for the purposes as stated herein. Any additional uses of this
water must first be approved by the State Engineer's Office.
8. The replacement water that is the subject of this SWSP cannot be sold or leased to any
other entity. As a condition of subsequent renewals of this SWSP, the 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 locations.
9. The name, address and phone number of the contact person who will be responsible
for the operation and accounting of this SWSP must be provided with the accounting
form to the division engineer and water commissioner.
10. Adequate accounting of depletions and replacements must be provided to the division
engineer in Greeley (Div1Accountinq state.co.us) and the water commissioner
(George Varra at Georqe.Varrastate.co.us) on a monthly basis. The accounting form
provided with your application is subject to modification and approval by the division
engineer. All volumes shall be in acre -feet.
In addition, it is the applicant's responsibility to verify that the entities making
replacements are identifying this use on their accounting submitted to our office. For the
period of this plan, that entity is City of Greeley (WDID 0303330 - GLIC Accounting).
11. All water pumped for dust control purposes shall be measured in a manner acceptable
to the division engineer.
12. The approval of this SWSP does not relieve the Applicant and /or 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 Tong -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 Division 1 Water Court at least three (3) years prior
to the completion of mining to include, but not be limited to, Tong -term evaporation
losses and lagged depletions. If a lined pond results after reclamation, replacement of
lagged depletions shall continue until there is no longer an effect on stream flow.
13. In accordance with the letter dated April 30, 2010 (copy attached) from DRMS, all
sand and gravel mining operators must comply with the requirements of the
Colorado Reclamation Act and the Mineral Rules and Regulations for the
protection of water resources. The April 30, 2010 letter from DRMS requires that
you provide information to DRMS to demonstrate you can replace long term
injurious stream depletions that result from mining related exposure of ground
water. The DRMS letter identifies four approaches to satisfy this requirement.
For the Derr Pit, it is our understanding that approach no. 1 or no. 3 will be
utilized as evidenced by the Applicant's proposal to obtain a bond in the amount
of $1,362,889 prior to the exposure of ground water at the Derr Pit. No
groundwater shall be exposed on the subject property until such time as the
applicant provides proof to this office (the Division of Water Resources) that
