| Description | This guidance documents an interpretation from the Department of Ecology regarding different procedures that should be used to calculate site contaminant concentrations for three types of contaminants when conducting a Terrestrial Ecological Evaluation (TEE) under the Model Toxics Control Act (MTCA). The three contaminant types are 1) Chlorinated dibenzo-p-dioxins (PCDDs), 2) Chlorinated dibenzofurans (PCDFs), and 3) Polychlorinated biphenyls (PCBs). This memorandum specifically pertains to Ecological Risk Assessment and TEEs under MTCA (WAC 173-340-7490 through -7494). |
