The design for the temporary fresh water line was <br /> developed by AMEC Foster Wheeler (Figures 1 and 2) in response to a fresh water release <br /> identified by Newmont on May 23, 2016 and is described below. A verbal notification was made <br /> to DRMS on May 24, 2016 and a written Update was provided on June 9, 2016. <br /> Background <br /> • Monday, May 23, 2016 a loss of approximately 300 gallons per minute of fresh water <br /> was noticed at the mill. A pipeline inspection found a water leak at the toe of the East <br /> Cresson Overburden Stockpile Area (ECOSA) near where the fresh water line is buried <br /> under the facility. The fresh water was captured in the existing stormwater collection <br /> system; specifically in the ECOSA Toe Road BMP 20 Sump, which flows into the Rip <br /> Rap Ditch, and ends in the larger EMP 020 sediment pond. <br /> • Tuesday, May 24, 2016 a ditch was dug to ensure all freshwater flows directly into EMP <br /> 020 bypassing the other stormwater structures. An internal geotechnical inspection was <br /> completed on the entire face of the ECOSA dump determining the stability of the <br /> ECOSA is not compromised. <br /> • Daily inspections and weekly scans have been conducted by the geotechnical, <br /> environmental, projects, and operations departments. No change in conditions has been <br /> observed. <br />
