Table 3. Weekly velocity and discharge from Stinky Pond culvert.

The Global Flow FP101 portable flow meter requires very little maintenance and calibration. The calibration factors are both preset and provided in the manufacturers manual. These are verified regularly to ensure accurate data is being collected. Ore Milled Due to the suspension of all mining and milling activities, there has been no ore milled in 2017 to date. Waste Rock Lithology Due to the suspension of all underground activities, there are no recent waste rock samples to report. Weekly Waste Rock ARD Due to the suspension of all underground activities, there are no recent waste rock samples to report. Mill Tails ARD Due to the suspension of all milling activities, there are no mill tailings assay results to report. Tailings Management Water elevations in TP4 and TP5 are visually monitored daily during TSF inspections. Table 4. 2019 weekly waste discharged to TSF.

A Sparling Model 8712 C/U/H (4) flow meter was installed in 2005 to measure total effluent discharged from the sewage treatment plant. The flow meter was installed and is operated as per the manufacturers instructions. Calibration of the flow meter is completed prior to leaving the manufacturer and does not require field calibration. WWTF The WWTF was de-commissioned and winterized on November 12th, 2015, as per the care and maintenance plan. No discharge has occurred to date. Flat River Hydrology Table 5.

Care and calibration of leveloggers is minimal. The water quality in the Flat River is of good quality and exhibits little impact on the loggers. When water levels are low (spring and fall) leveloggers and casings are inspected for buildup of solids or calcium deposits that may inhibit the leveloggers ability to record reliable data. These are cleaned as per the manufacturers recommendations. The Swoffer velocity meter and sensor are maintained regularly in order to maintain accurate outputs. Equipment is inspected prior to each use to ensure that it is in an acceptable operating state and to limit the potential for erroneous data. Equipment is also cleaned and stored in their carrying cases after each use. Calibration activities are conducted often as per the manufactures recommendations, and readings are verified by methods outlined in the care and calibration manual prior to each use. Unauthorized Discharges There were no unauthorized discharges in January. Table 7. Fuel tank inspections.
