Ready Mix Concrete Substitute Water Supply Plan <br /> February 13, 2020 <br /> Page 9 of 10 <br /> 13. The name, mailing address, and phone number of the contact person who will be <br /> responsible for operation and accounting of this plan must be provided on the <br /> accounting forms to the division engineer and water commissioner. <br /> 14. Dewatering at Morton-Holton Lakes sites will produce delayed depletions to the stream <br /> system. As long as the pits are continuously dewatered at a relatively constant rate, <br /> the water returned to the stream system should be adequate to offset the depletions <br /> attributable to the dewatering operation. Dewatering, operations must be measured <br /> by totalizing flow meters that can accurately show the monthly volume of <br /> dewatered water that is pumped and returns to the stream. If dewatering at the <br /> site ceases, or is significantly reduced, the monthly meter readings will be used to <br /> determine post pumping depletions that must be replaced. At least three years prior <br /> to completion of dewatering, a plan must be submitted that specifies how the post <br /> pumping dewatering depletions (including refilling of the pit) will be replaced, in <br /> time, place and amount. <br /> 15. In accordance with the letter dated April 30, 2010 (copy attached) from the Colorado <br /> Division of Reclamation, Mining, and Safety ("DRMS"), all sand and gravel mining <br /> operators must comply with the requirements of the Colorado Reclamation Act and the <br /> Mineral Rules and Regulations for the protection of water resources. The April 30, <br /> 2010 letter from DRMS requires that you provide information to DRMS to demonstrate <br /> you can replace long term injurious stream depletions that result from mining related <br /> exposure of groundwater The DRMS letter identifies four approaches to satisfy this <br /> requirement. <br /> In accordance with approach nos. 1 and 3, you have indicated that a bond has been <br /> obtained for $4,150,000 for the Morton-Holton Lakes site through the DRMS to assure <br /> that depletions from groundwater evaporation do not occur in the unforeseen event or <br /> events that would lead to the abandonment of the Pit. <br /> 16. All releases of replacement water must be sufficient to cover all out of priority <br /> depletions and be made under the direction and/or approval of the water <br /> commissioner (including the proposed aggregated replacement for winter depletions). <br /> 17. The approval of this SWSP does not relieve the Applicant and/or landowner of the <br /> requirement to obtain a Water Court decree approving a permanent plan for <br /> augmentation or mitigation to ensure the permanent replacement of all depletions, <br /> including long-term evaporation losses and lagged depletions after gravel mining <br /> operations have ceased. If reclamation of the mine site will produce a permanent <br /> water surface exposing groundwater to evaporation, an application for a plan for <br /> augmentation must be filed with the Division 1 Water Court at least three (3) years <br /> prior to the completion of mining to include, but not be limited to, long-term <br /> evaporation losses and lagged depletions. If a lined pond results after reclamation, <br /> replacement of lagged depletions shall continue until there is no longer an effect on <br /> stream flow. <br /> 18. The State Engineer may revoke this SWSP or add additional restrictions to its operation <br /> if at any time the State Engineer determines that injury to other vested water rights <br />
