Paul Weiss, P.E. Page 4 <br />Journey Ventures Pit Amendment November 17, 2015 <br />All amounts shall be in acre-feet. All submitted accounting must conform to the Administration <br />Protocol "Augmentation Plan Accounting - Division One, South Platte River" (attached). <br />In addition, the Applicant shall verify that the entity making replacements has included the <br />Applicant on their accounting and submitted their accounting to the division office and the water <br />commissioner; for this SWSP, that entity is the City of Greeley. <br />6. 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 operators <br />must comply with the requirements of the Colorado Reclamation Act and the Mineral Rules <br />and Regulations for the protection of water resources. The April 30, 2010 letter from DRMS <br />requires that you provide information to DRMS to demonstrate you can replace long term <br />injurious stream depletions that result from mining related exposure of ground water. The <br />DRMS letter identifies four approaches to satisfy this requirement. <br />In accordance with approach nos. 1 and 3, you have indicated that a bond has been obtained <br />for $349,524 through the DRMS to assure that depletions from groundwater evaporation do <br />not occur in the unforeseen event, or events, that would lead to the abandonment of the Pit. <br />7. Dewatering operations must be measured by totalizing flow meters that can accurately show the <br />monthly volume of water dewatered into the silt pond and the recharge. Any dewatering water <br />placed into silt pond and recharge pond cannot be used for any purpose by the operator, and <br />must be allowed to accrete to the stream. The provision in the SWSP allowing the silt pond <br />and the recharge pond may not be continued in SWSP renewals should it be determined by <br />the water commissioner or division engineer that water within the silt pond and the recharge <br />pond is being diverted for use and accounting is not adequate to show the recharge of <br />dewatering is occurring. <br />If you have any questions concerning this approval, please contact loana Comaniciu in Denver at <br />(303) 866-3581 or Michael Hein in Greeley at (970) 352-8712. <br />Sincerely, <br />Jeff <br />Chief o <br />Attachment: Figure 1 <br />Tables 1, 2 and 3 <br />rage, P.E., <br />ater Supply <br />cc: Michael Hein, Assistant Division Engineer, Mike.Hein@state.co.us <br />Evan Snyder, Water Commissioner, District 1, Evan.Snyder@state.co.us <br />Brent Schantz, River Operations a Compact Coordinator, Brent.Schantz@state.co.us <br />Division of Reclamation Mining and Safety <br />
