RECOMMENDED MONITORING PROGRAM <br />Due to the marginal stability conditions present on the site, and <br />the potential for intermittent periods of instability, it is <br />recommended that the monitoring system installed during the site <br />investigations be maintained during the life of the mine and for <br />a period of one year after reclamation, to establish that stable <br />conditions prevail. The elements of this monitoring system <br />consists of: <br />o Water level measurements in the four piezometers <br />installed within site borings. <br />o Periodic surveying of slope monuments for determining <br />slope movements. <br />It is recommended that monitoring during the operational phase <br />~ begin on a weekly basis, with extension of the monitoring <br />interval as may be appropriate after sufficient baseline data has <br />been collected. Monitoring during reclamation and post- <br />reclamation phases should be quarterly unless results of <br />monitoring show signs of instability. If this occurs, then <br />~ monitoring frequency should be increased. <br />we hope this report has provided you with all of the information <br />~ you required and that it has been presented in an understandable <br />way. Should any of the points be unclear, or should you require <br />additional information, please do not hesitate to contact our <br />1 office. It should also be pointed out that because of the nature <br />of the data obtained by random sampling of such variable and non- <br />1 homogeneous materials as soil and rock, it is important that we <br />be informed of any differences observed between the surface and <br />• subsurface conditions encountered during reclamation, and those <br />13 <br />t <br />
