| Short Description |
Ecology conducted a Class II Inspection at the Aluminum Company of America (ALCOA) operations near Vancouver, Washington, on January 28 31, 1990. All industrial effluent loadings were less than the daily maximum permit limits, except oil and grease and benzo(a)pyrene. Effluent biochemical oxygen demand and total suspended solids concentrations were less than the sanitary effluent permit limits. Residual chlorine was greater than the permit limit in one grab sample. (Also see abstract below) | |||

| Abstract | Long Description |
Ecology conducted a Class II Inspection at the Aluminum Company of America (ALCOA) operations near Vancouver, Washington, on January 28 31, 1990. All industrial effluent loadings were less than the daily maximum permit limits, except oil and grease and benzo(a)pyrene. Effluent biochemical oxygen demand and total suspended solids concentrations were less than the sanitary effluent permit limits. Residual chlorine was greater than the permit limit in one grab sample. No acute or chronic toxicity was indicated in the industrial effluent (001) by rainbow trout, Microtox®, Daphnia magna, or fathead minnow. Analysis results for the Near Outfall sample showed a relatively clean sediment. No acute toxicity was indicated by Hyalella azteca in the Near Outfall sediment sample. Lab results for permitted parameters compared well between ALCOA and Ecology although significant deficiencies were found in the laboratory review. |
