Mr. Peter Hays <br /> TR-28 - Ute Park Extraction Wellfield <br /> February 12, 2018 <br /> Henderson Response: The Hydrostatic Testing Memo has been reviewed and updated, <br /> as requested. See Attachment 2. A memo from W.W. Wheeler explaining the <br /> discrepancies is also included. See Attachment 4. <br /> 4. The extraction well outlet pipe diameter in Details 1, A/3 and 2 on Sheet 3 of the <br /> Henderson 1 Dam Extraction Well Project Seepwater Collection Pipeline Phase III <br /> (Wells MLEX-4, MLEX-5) drawings by W.W. Wheeler and Associates, Inc., Revision <br /> Date 12/13/17, indicates the outlet diameter from the Extraction Well Vault as 4"DR 17 <br /> HDPE Pipe. As stated in Question #3 above, the Henderson Mill Seepwater Collection <br /> System Piping Hydrostatic test memo dated October 31, 2017 from Doug MacLaren, <br /> P.E. states the discharge line from MLEX-5 is a 3-inch HDPE line. Please explain this <br /> discrepancy and update the memo and/or the as-built sheet accordingly. <br /> Henderson Response: The As-Builts have been reviewed and updated, as requested. It <br /> was determined that the as-built discrepancies mentioned on Sheet 3 are accurate in the <br /> original version so they were not changed. However, during review an error was noticed <br /> on Sheet 2. The size of the 4"line coming from the vault was incorrect. This has been <br /> corrected. See Attachment 3. The aforementioned memo from W.W. Wheeler explains <br /> the correction. See attachment 4. <br /> If you have any other questions or need any additional information, please do not hesitate to <br /> contact me at aparmetfmi.com or (720) 942-3480. <br /> Regards, <br /> Amber Parmet <br /> Senior Environmental Engineer <br /> Climax Molybdenum Company <br /> Henderson Operations <br /> Attachments: <br /> 1.
