Therefore, all recorded monitoring events are considered Operational. Alluvial Welts AW-7 through AW-9 are boated south of Old Stale Highway 133, near the entrance to the mine. They were installed in 1999 as the result of PR-03. There is no Baseline Collection possible for points initiated after the influence of mining. Monitoring Point Table 110 Revised 03/04
