Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
All records and log books appeared to be complete and well maintained. A copy of the current NPDES
permit was available for review. The ORC visitation log appeared to be complete and current.
Calibration records for equipment was being properly documented. Laboratory data was reviewed and
all data appeared to be correct, as reported on the DMR's. The annual compliance report had not been
done for the previous year. Literature and instructions were given to Mr. Deese, ORC, explaining the
requirements for completing the annual report. The facility, overall, appeared to be neat and well
maintained and all treatment units appeared to be in proper working order. The effluent was very clear
and appeared to have no visible pin floc at the time of this inspection.
