Publication Summary

A Class II inspection was conducted at the Central Kitsap Wastewater Treatment Plant on January 26-28, 1998. The plant was performing well during the inspection. The effluent met National Pollutant Discharge Elimination System permit limits for all parameters: 5-day carbonaceous biochemical oxygen demand, total suspended solids, fecal coliform, and pH.

The effluent met National Pollutant Discharge Elimination System permit limits for all parameters: 5-day carbonaceous biochemical oxygen demand, total suspended solids, fecal coliform, and pH.

Modifications to the plant scheduled for 1999 should remedy some conditions found during the inspection. These conditions included unsteady flow in the Parshall flume, the lack of a continuously reading totalizer, the inability to include septage contributions in samples of plant influent, and the collection of rags on the influent sampler intake. Central Kitsap should also review its CBOD analysis procedures.

Organic compounds found in the effluent were in concentrations below applicable water quality criteria. Copper was found in the effluent in concentrations exceeding acute and chronic water quality criteria. TSDCALC7 indicates no reasonable potential to violate water quality standards for copper or any of the other metals found in the effluent.

The sludge sample exceeded the fecal coliform count for EPA Class A sewage sludge but met Class B requirements. All metals found in the sludge were in concentrations lower than EPA sludge application limits and ceiling concentrations for application of municipal sludge.
