1. Laboratory results were reviewed for the months October and November, 1998. All records were
neat and in order.
2. Aqua -Tech Environmental Laboratories, Inc. is the commercial lab that analyzes all parameters
other than pH and temperature which are done in house. Calibration logs were on site for pH.
3. NPDES permit was available upon request.
4. The effluent flow meter was calibrated October 7, 1998 by Fisher & Porter. It is advisable that the
flow meter calibration document contain the % error before and after calibration in the future by the
technician.
5. This facility no longer receives wastewater from the BCH Energy company because it no longer
exists.
6. The Predigester tank was out of service due to pipe replacement.
7. The Equalization Basin was operational.
8. Clarifier #1 appeared to have light floc passing over the weirs. The sludge depth was measured in
the clarifier at <(less than) 1 foot of solids.
9. Clarifier #2 appeared to have light floc passing over the weirs also. The sludge depth was measured
in the clarifier at >(greater than) 1 foot of solids.
10. Sludge is removed from the clarifiers to the "DAF" unit and from there to the sludge holding tank.
The sludge is then pressed, dewatered and dried and placed in bins to be delivered to "BFI" site in
Roseboro where it is disposed.
11. Maintenance records and schedules are on computer.
12. The effluent appeared to be visably clear.
13. The effluent outfall was easily accessible.
