Backup WWTP ORC Christopher Ladd was not available and so I did the inspection with Bill Bateman who is the WTP ORC. The pH levels in the clarifiers and outfall were all high, right at 9.0 su. This is within compliance but just barely. Mr. Bateman said that the clarifiers are planned to be pumped at 8-10 year intervals. Given that one of the clarifiers had an upset a couple years ago and released solids, it may be wise to pump solids out of the clarifiers more frequently. The effluent pipe was submerged. There were strange growths/deposits in the receiving channel. I assume that is due to fluctuating pH level of the effluent. The dechlorination system has not been needed to meet effluent permit limits for chlorine, according to Mr. Bateman. This system did not have the chemicals needed to operate it on site, but he said that he could have the necessary chemicals delivered on the same business day as needed. NC0069892 17 (Cont.)

Does the facility analyze process control parameters, for ex: MLSS, MCRT, Settleable Solids, pH, DO, Sludge Judge, and other that are applicable? Comment: Effluent Pipe Yes No NA NE Is right of way to the outfall properly maintained? Are the receiving water free of foam other than trace amounts and other debris? If effluent (diffuser pipes are required) are they operating properly? Effluent pipe was under water. Strange growths/deposits in the receiving waters.Comment: Secondary Clarifier Yes No NA NE Is the clarifier free of black and odorous wastewater? Is the site free of excessive buildup of solids in center well of circular clarifier? Are weirs level? Is the site free of weir blockage? Is the site free of evidence of short-circuiting? Is scum removal adequate? Is the site free of excessive floating sludge? Is the drive unit operational? Is the return rate acceptable (low turbulence)? Is the overflow clear of excessive solids/pin floc? Is the sludge blanket level acceptable? (Approximately ¼ of the sidewall depth) South clarifier has never had solids pumped out. North clarifier had solids pumped out about a year ago.
