| Description |
A Class II Inspection was conducted in May 1992 at the Spokane Industrial Park Sewage Treatment Plant. The Spokane Industrial Park facility treats wastewater from a varieteria included in the NPDES permit. Influent flow exceeded 85% of design criteria. All effluent organic compound concentrations were within EPA water quality criteria. Effluent concentrations of copper, lead, and silver exceeded EPA chronic water quality criteria for receiving waters. Effluent bioassays provided evidence of toxic effects. The toxicity may have been related to chlorine residual. Sodium adsorption ratio, pH, and coliform concentrations in industrial wastewater were of concern for sprayfield application. The inspection identified high fecal coliform counts and small to moderate organic/metal concentrations in the industrial influent. |
