Abstract Long Description

Ecology conducted a Class II inspection at the Spokane wastewater treatment plant (WTP) on September 20-22, 1988. The 44 MGD design activated sludge facility serves the City of Spokane and portions of the greater Spokane area. This inspection coincided with a receiving water study conducted by the Ecology Surface Water Investigations Section (Carey, report in progress). The WTP was performing well during the inspection, meeting permit limits for BOD, TSS, NH3-N, and total phosphorus. However, fecal coliform bacteria in a treated effluent sample was above the weekly average permit limit. The effluent was not acutely toxic as measured by Rainbow trout, Daphnia pulex, and Microtox bioassays.
