-3- <br />Piezometers <br />The inspection report recommends continued observations at the 360-level <br />piezometer and, if there is no decline in water level replacement of the <br />piezometer. Observations have continued and no substantial decline has been <br />measured. Thus the peizometer may be plugged or the casing disturbed. It <br />appears that HMC may have to replace this piezometer in 1985. We will continue <br />to analyze the water level data to confirm the need for replacement. <br />Dumb Records <br />The inspection report recommends weekly reports to be kept to record the <br />daily inspections of dump status. These reports are being maintained. <br />Pit Access Road Slide <br />No recommendations for near-term implementations were made in the <br />inspection report. <br />The majority of the recommendations involve regrading of the rock dumps in <br />access where erosion along the working dump faces has occurred. Though the <br />sediment contro]s in place at the sedimentation pond have kept any effects of <br />this erosion within acceptable limits, Homestake has maintained its maintenance <br />program to minimize erosion of the dumps. At the current stage of operations, <br />the maintenance is often combined with the revegetation activities. <br />If our report elicits questions, please tali. You and Dr. Pendleton may <br />wish to meet with me to ensure we have adequately explained our activities. <br />Best wishes for the Holidays and thanks for your time and effort. <br />Sin~er~ely, ~ <br />n E.
