Description A Class II inspection was conducted at the City of Sumner Wastewater Treatment Plant (WWTP) on April 22-24, 1996. The plant was performing marginally during the inspection. The conventional parameters of BOD5 and TSS indicate effective biological and physical treatment. However, effluent BOD5 loading exceeded the permitted monthly average, and percent BOD5 removal was slightly less than the monthly average requirement. Fecal coliform counts were high, exceeding the permitted monthly average, and the effluent chlorine concentration exceeded the daily maximum permit limit. Improvements in regulating chlorine and sulfur dioxide concentrations are recommended.
