Class II Inspection of Wyerhaeuser, Longview Pulp and Paper Mill, April 16-18, 1990

Sediment was sampled at three stations in April 1990 near the
Weyerhaeuser's pulp and paper mill waste treatment plant outfall.
Sediments were sampled for dioxins, furans, volatile and semivolatile
compounds, metals, organochlorine pesticides and PCBs. Sediment
samples were taken near the point of effluent discharge, at a point
300 ft downstream from the discharge, and at a point 4500 ft upstream
from the point of discharge. Conventional analyses included TOC and
grain size.

The objectives of the Weyerhaeuser, Longview Pulp and Paper Mill's
Class II Inspection were to verify effluent compliance with NPDES
permit (NPDES Permit No. WA-000012-4), characterize priority and
non-priority pollutants in industrial in-plant waters, treatment
effluent and in sediments near the 001/002 outfall, determine the
removal efficiency achieved with secondary treatment of industrial
streams, evaluate any toxicity in the 001/002 effluent and sediments
using several bioassays and to characterize any priority pollutants in
the Radakovitch landfill leachate or in the R-W Paper plant drainage
into Longview Ditch #3 (Andreasson 1991). The inspection also
reviewed lab procedures at the mill to determine adherence to accepted
protocols and advance state-of-the-art compliance inspections by
contributing to ongoing developmental efforts with centrifugation.

The area of study was Lower Columbia River, Longview. The sampling
locations were near the Weyerhaeuser's pulp and paper mill's waste
treatment plant outfall. Samples were collected next to the 54"
diffuser outfall pipe, approximately 300 ft downstream from the
diffuser and approx

Individual sample grabs were placed on ice and delivered to the
laboratory.

Target analytes included Dioxin/furans; volatile and semivolatile
compounds; metals (Sb, As, Be, Cd, Cr, Cu, Pb, Hg, Ni, Se, Ag, Ti, and
Zn); organochlorine pesticides and PCBs. Conventional analyses
included TOC and grain size.

Analytical techniques included Dioxin/furans (EPA 8290); VOAs (EPA
8240), BNAs (EPA 8270), metals (EPA 7041, 7060, 6010, 7131, 7421,
7740, 7841), pesticides/PCBs (EPA 8080). All results, except for
mercury, were reported on a dry weight basis. Mercury results were
converted to dry weight basis for entry into the database using the
reported percent solids content of the sediment. Total dioxin and
furan concentrations were determined by the laboratory as the sum of
the individual congeners that were detected.

The information for this metadata was taken from the Columbia River
Basin: Sediment Database Abstracts.
