Mr. Roger Schmidt <br /> March 15, 2017 <br /> Page 2 <br /> December 14, 2016) and Wright Water Engineers, Inc. Letter to City of Greeley dated <br /> September 2, 2016." <br /> WWE's responses incorporate information from our initial investigation and also include <br /> information obtained in the past month, including: <br /> 1) Observations made by Ian Paton, P.E. during a field visit to the location of the pipeline <br /> breach, conducted on February 6, 2017. <br /> 2) Information gained from interviewing City of Greeley personnel who are tasked with <br /> operating and maintaining the pipeline that was breached. <br /> 3) Findings from interviewing the engineer responsible for the design of the subject pipeline <br /> as well as for construction observation. <br /> 4) Photographs of the area of interest taken on May 27, 2014 at the early stages of the flood <br /> event that damaged the pipeline and caused the erosion in the field west of the pipeline. <br /> The responses from WWE address the DRMS inspection report, the Al comment letter and the <br /> Tetra Tech comment letter, in that order. <br /> Comments on the DRMS Inspection Report, signed December 4, 2016 <br /> The DRMS Mineral Program Inspection Report documents the inspection of the 83`d Joint <br /> Venture Site that was conducted on July 12, 2016. Participants in the inspection were Mr. Peter <br /> Hays and Mr. Wally Erickson with the DRMS, Ms. Connie Davis and Mr. Mike Refer with Al, <br /> and Ms. Christie Coleman and Mr. Eric Reckentine with the City of Greeley. <br /> DRMS letter,p.2 , last paragraph: <br /> The DRMS letter text states, "The pipeline was not operational at the time of the inspection due <br /> to leaking joints in the pipeline. The joints were scheduled to be repaired soon. Groundwater <br /> was flowing from the manhole and vault located in the reconstructed portion of the pipeline. " <br /> WWE Comment: <br /> For clarification, it is important to note that the section of pipeline noted as being non- <br /> operational due to leaking joints is just the section of pipe (an inverted siphon) that was <br /> installed in 2016 to temporarily repair the portion of pipeline damaged in 2013 and 2014. <br /> The original portion of the pipeline that was not damaged in 2014 is still intact and has no <br /> evidence of leakage. <br />
