Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) All records and log books were very well organized and maintained. A copy of the NPDES permit and the most recent annual report were available for review. The ORC visitation log appeared to be complete and current. Calibration records for equipment appeared to be properly documented. Laboratory data was reviewed and all data that was reviewed appeared to be correct, as reported on the DMR's. At the time of this inspection, one of the aerator brushes in one of the oxidation ditches was out of service due to a bad bearing and the gearbox for one of the clarifiers had gone bad. Both pieces of equipment were in the process of being repaired. Also, there are trees and vegetation growing in the bottom of the unused digester. This material needs to be removed and any damages caused by the growth of the vegetation needs to be repaired. At the time of this inspection, the effluent appeared to be very clear with no visible solids present. As part of this inspection, effluent samples were collected and sent to the Division of Water Resources laboratry for analysis. The results of the samples are listed below.
