The <br /> Colorado Division of Reclamation, Mining and Safety (The Division), has reviewed the above referenced reports, <br /> received by The Division on 13 July 2021. Sediment pond inspections were conducted by Miranda Kawcak as follows: <br /> Year Quarter Date <br /> 4 18-Nov <br /> 2019 3 26-Sep <br /> 2 18-Jun <br /> 1 26-March <br /> 2018 4 30-Oct <br /> This report appears to be in compliance with the applicable sections of Rule 4.05.9. No maintenance items were noted <br /> during the inspection with the exception of the weir at outfall 022. This weir is showing signs of rust,allowing water to seep <br /> around or below it while flowing. This should be replaced. Rodent burrows were noted at ponds SHPIand SHP2,outfalls 11 <br /> and 12;as well as at outfalls 24 and 14,the 9P series of ponds. The burrows are being monitored. <br /> None of the ponds held measureable water at the times of inspection,although a small pool in pond 9A-P1 is occasionally <br /> noted in Q2 inspections. The ponds are generally dry and have never discharged. Sediment storage was adequate for all <br /> ponds at time of inspection. The spoil spring(outfall 022),pools on occasion and generally only discharges in spring. The <br /> spoil spring(Outfall 22)showed approximately 2"of water in the weir with a discharge of approximately 0.025 cfs and 0.02 cfs <br /> as per the 18 June and 26 March inspection reports respectively.Ponds reclaimed in 2018 comprise ponds 5P-5,5P-6 and 5P-7 <br /> and the wastewater treatment pond was reclaimed in spring of 2019. Ponds P2,P3 and P4 have been designated as permanent <br /> features as stock ponds. <br /> With the exception of the weir at outfall 022 requiring replacement or repair,the Division has no concerns. <br /> Best Regards, <br /> Robin Reilley,M.S.
