Therefore, all recorded <br />monitoring events are considered Baseline. <br />Shallow monitoring wells SM-1 through SM-11 were constructed in 1985 in order to gather additional information <br />on alluvial/colluvial deposits within the permit boundary. They are depicted on Map 4-1. <br />Baseline Information Collection initiated on 8/3/85 and not ye[ considered complete. <br />Point SMOG has not been intluencetl by mining. <br />Monitoring Point Table 15 <br />(Revisetl 03/04) <br />
