| Short Description |
A Class II Inspection was conducted in April 1993 at the Kaiser Aluminum and Chemical Corporation, Tacoma Reduction Plant. The facility discharges industrial process noncontact cooling water and stormwater runoff. The inspection data found Kaiser discharging a good quality effluent for the parameters analyzed. Effluent concentrations were generally within the NPDES permit limitations. With the exception of copper, effluent priority pollutant concentrations were below the marine acute and chronic EPA Water Quality Criteria. Bioassay testing documented no effluent toxicity. High levels of oil and grease were detected in the 004 storm sewer. Kaiser lacks a flow totalizer. An improved method for measuring flow should be investigated. | |||
