| Abstract | Long Description |
A Class II Inspection was conducted at the Weyerhaeuser Company Wood Products Division - Snoqualmie Facility (Weyco) on February 16, 1993. Sediment samples were collected from the inactive log pond on February 9, 1993. Due to an extended period of dry weather, the inspection objective to sample during run-off conditions could not be met. The discharge from the silvacel production facility into the log pond carried a heavy load of solids and oxygen demand parameters. The discharge from the log pond (001) met the limitations in the stayed NPDES permit, however, the silvacel facility discharge (002) exceeded the daily average but not the daily maximum limitations for TSS and BOD5. Bioassay test results demonstrated only limited toxicity of the effluent to one test organism. The sediments contained a number of organic compounds and high levels of oil and grease. Bioassay test organisms were sensitive to the sediments. Recommendations to improve self-monitoring are made. |
