(QAlQC) Plan.
Vacuum on the tailing lysimeters was verified on October 31~`, no water was present for sampling
and subsequent analysis.
Depths to water were collected for the tailing impoundment main embankment piezometers and
the West Pit and tailings embankment monitoring welts on October 31u. October tailing
impoundment piezometer measurements identified these installations were either dry or contained
less than ]2 inches of water as illustrated in Table 2. Tables 1 and 2 below identify the depth to
water measurements collected for each of the site monitoring wells, piezometers and lysimeters as
required by the terms and conditions of the TR-32 QA/QC plan.
The tailing impoundment collection pond underdrain flow was pumped intermittently during the
month to minimize the collection pond level. The leak detection system was measured on October
30`". The October tailings pond underdrain flow average was 38.72 gem and a total of 860 gallons
of water was excavated from the leak detection system yielding a monthly average of 26.88 gpad.
During October the West Pit water treatment plant operated efficiently discharging a total of
8,962,900 gallons (27.51 acre-feet) of water to Rito Seco Creek and a total of 1,004,100 gallons
