<br />P14 N 205,855 <br />E 2,037,569 <br />, .~ A . <br />P15 N 206,066 <br />E 2,037,500 <br /> <br />The design is consistent with the 8590' embankment <br />piezometers installed in September 1993. As outlined in the <br />Division's November 2, 1993 letter, the piezometers were <br />constructed such that the bottom cap is at or near the <br />contact of the embankment fill material and the tailings <br />with a 10' screen interval in the fill material directly <br />above the cap. The embankment piezometers will be monitored <br />monthly. <br />Five in-tailings piezometers were also installed. These <br />piezometers are identified as P15-P20. The coordinates for <br />the in-tailings piezometers are: <br />P16 N 205,295 <br />E 2,037,825 <br />P17 N 205,480 <br />E 2,037,750 <br />P18 N 205,671 <br />E 2,037,706 <br />P19 N 205,762 <br />E 2,037,691 <br />P20 N 206,096 <br />E 2,037,580 <br />The Division provided BMRI with a schematic of in-tailings <br />piezometers which was prepared by Water, Waste, and Land. <br />BMRI followed the design provided by the Division for the <br />installation of the ~n-tai_]incTS piezometers <br />As outlined in the Division's January 6, 1994 memo to file, <br />the access to the in-tailings piezometers for the purpose of <br />bailing and monitoring will be dependent upon the <br />depositional sequencing. As stated by the Division, <br />quarterly readings - flexible in that monitoring should be <br />performed at least 4 times per annum on dates as equally <br />spaced as possible depending on accessibility - will be <br />collected and recorded. <br />BMRI continues to be concerned about the quality and <br />interpretation of data obtained from the in-tailings <br />piezometers. Obviously, as tailings are deposited around <br />the screened interval of the standpipe, water will be <br />collected in the piezometer. Once the screened interval is <br />buried by tailings, the piezometers will lxkeiy collect <br />
