The area oI concern for monitoring point D34-12 has not been affected by the mining operation. There/ore, all recorded
monitoring events are considered Baseline.
The D34-12 Monitoring point is at the discharge of Imn Point Gulch. The field parameters and flow values are taken at the
discharge end o/a 36" CMP that passes under Hubbard Creek Trail.
Baseline Information Collection initialed on 10/31/97 and not yet wnsitlered complete.
Point D3412 has not been in6uencetl by mining.
