Appendix A Statement of Task and Committee Biosketches STATEMENT OF TASK A multidisciplinary committee will independently evaluate the Coeur dâAlene River basin Superfund site in northern Idaho as a case study to examine the U.S. Environmental Protection Agencyâs (EPAâs) scientific and technical practices in Superfund site area characterization, human and eco- logical risk assessment, remedial planning, and decision making. The com- mittee will assess the adequacy and application of EPAâs Superfund guid- anceâin this case, in terms of currently available scientific and technical knowledge and best practices. Recognizing that substantial actions have already been taken to assess and remedy some of the risks attributable to the Coeur dâAlene site, the committee will strive to provide guidance to facilitate scientifically based and timely decision making for this site in the future. The committee will discuss remedial options but will not recom- mend a specific remedial strategy for this site. The committee will assess the scientific and technical aspects of the following: â¢ Determining the geographical extent of areas contaminated by waste site sources. What types of data and analysis are necessary to assess the extent of contamination? In this case, did the approaches used to collect and analyze the data provide results that adequately support EPAâs conclu- sions? Were the sources, transport, and fate of identified contaminants properly considered? 431
432 APPENDIX A â¢ Assessing and apportioning risks to humans from multiple contami- nant exposures related to waste site sources as well as other sources (for example, lead exposure via soil and house-paint dust). What techniques should be used to identify contaminants of concern and estimate the human health risks attributable to waste site sources? In this case, were risks attrib- utable to sources other than mining and smelting activities adequately analyzed? â¢ Estimating blood lead levels in children with the integrated exposure uptake biokinetic model. Are the design, input data, and assumptions of this model consistent with current scientific understanding? In this case, was the model appropriately applied given the local and regional character- istics? Were alternative tools appropriately used to assess and interpret the model results? â¢ Assessing the ecological risk from waste site contaminants in the context of multiple stressors. What are the necessary data and appropriate analyses to estimate the ecological risks attributable to waste site contami- nants? In this case, how well were these analyses applied to estimate the risks, including the effects of lead on migratory fowl? Were risks attri- butable to sources other than mining and smelting activities adequately analyzed? â¢ Defining the remediation objectives. What factors should be consid- ered in selecting the remediation objectives? In this case, did EPA use an appropriate scientific rationale in selecting the remediation objectives, in- cluding the spatial extent and levels of remediation? Was this scientific rationale adequately explained? Were the limitations of the analyses appro- priately described? â¢ Evaluating the remediation approaches. In this case, were the feasi- bility and potential effectiveness of the remediation plans adequately char- acterized, given best engineering and risk practices and the site-specific characteristics? Was an adequate set of alternatives considered? â¢ Lessons from the Coeur dâAlene case that may be applicable to similar Superfund sites. Do new approaches need to be developed in the Superfund program to assess the extent of contamination, the resulting health and ecological risk, and possible remediation strategies where water and/or air have distributed contamination over extensive geographical areas?
