Morton Lakes Substitute Water Supply Plan Renewal <br /> January 10, 2025 <br /> Page 12 of 14 <br /> 17.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 /> 18. Dewatering at this site will produce delayed depletions to the stream system. <br /> Dewatering operations must be measured by totalizing flow meters that can <br /> accurately show the monthly volume of dewatered water that is pumped and returns <br /> to the stream. At least three years prior to completion of dewatering, a plan must be <br /> submitted that specifies how the post pumping dewatering depletions (including <br /> refilling of the pit) will be replaced, in time, place and amount. <br /> 19.The Applicant must replace all depletions resulting from operations under this SWSP, <br /> including those depletions that are owed to the stream after the expiration date of <br /> this SWSP. The Applicant must maintain a valid SWSP approved under section 37-90- <br /> 137(11 ), C.R.S. until all lagged replacement obligations resulting from the gravel pit <br /> operation have been fully replaced in time, location, and amount. <br /> 20. 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 <br /> the 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 <br /> or events that would lead to the abandonment of the Pit. <br />
