This addendum provides information regarding additional protection measures <br /> for potential avalanches in the vicinity of the Property Discharge Water Treatment Plant(PDWTP). <br /> The attached drawings show the design and location of a new avalanche deflection berm. The height of the <br /> berm as shown on the attached profile drawing will vary and is approximately 27 feet at the top,20 feet in the <br /> middle and 18 feet at the bottom,where avalanche debris will pile up. The berm will be constructed of fill <br /> material from local borrow sources and it will be capped with topsoil and seeded,as was done for the existing <br /> berm located uphill and across the west interceptor road from the new berm. <br /> The new berm is a continuation of the current avalanche protection measures for the PDWTP. We intend to <br /> construct the new berm in the next several weeks so that all work is completed prior to winter. <br /> Please accept this letter and attachments as an addendum to TR-19 for your files. Climax also will maintain <br /> this information with our copies of TR-19. <br /> Sincerely, <br /> Ray and Lazuk <br /> Environmental Manager <br /> attachments <br />
