Section D• Summary of Findings/Comments:
1. According to the DMR data reviewed for the period December 1995 through October 1996,
the plant's effluent was in compliance with the NPDES permit's limits.
2. Aqua -Tech Laboratory performs the "outside" permit required analytical work for the
facility.
3. All logs, calibrations, and records were being adequately maintained.
4. Fischer and Porter last checked/calibrated the effluent flow meter in October 1996.
5. On the day of inspection, a grab sample of the effluent revealed a settleable solids level of
a trace/ltr of settleable solids with a relatively clear supernatant in the test vessel (Imhoff

6. DMR and laboratory data agree for discharge pipe .001 for June 1996 (spot check).
7. Sludge is (was) routed from the bottom of the clarifier to the "DAF" unit and from there to
the sludge holding tank. The screw press then dewaters the sludge to about 12-14%. Dryers
then dewater the sludge to about 45-50%. It is then put in bins and delivered to `BFI" site
