Description This memorandum is an interpretation from the Washington State Department of Ecology for: 1) Evaluating detection limits and non-detects for the purposes of summing congeners for site evaluations; and 2) Establishing a PQL for dioxin-like congeners, specifically for a) Chlorinated dibenzo-p-dioxins (PCDDs), b) Chlorinated dibenzofurans (PCDFs), and c) Dioxin-like polychlorinated biphenyls (PCBs). This memorandum addresses Ecological Risk Assessment and the Terrestrial Ecological Evaluation under MTCA WAC 173-340-7490 through -7494.
