| Short Description |
A Class II Inspection was conducted at the Pendleton Woolen Mills Washougal Facility (Pendleton) on April 19-21, 1993. The facility treats process wastewater using an activated sludge process and discharges treated effluent to the Columbia River. Waste activated sludge is spray irrigated on site. Inspection results were within the daily maximum NPDES permit limits and were also less than the daily average limits. (Also see abstract below) | |||

| Abstract | Long Description |
A Class II Inspection was conducted at the Pendleton Woolen Mills Washougal Facility (Pendleton) on April 19-21, 1993. The facility treats process wastewater using an activated sludge process and discharges treated effluent to the Columbia River. Waste activated sludge is spray irrigated on site. Inspection results were within the daily maximum NPDES permit limits and were also less than the daily average limits. Concentrations of the four priority pollutant organic scan compounds detected in the effluent were less than applicable water quality criteria. Effluent copper, zinc, lead, and mercury concentrations exceeded acute and/or chronic water quality criteria. Bioassays found no toxicity due to the effluent. Sludge metals concentrations were less than the guidelines above which land application of municipal sludge is restricted. Sediment composition and chemistry near the Pendleton outfall indicated minimal impact due to the discharge. |
