The report describes the simplest member of a sequence of Source Analysis Models (SAMs) of increasing complexity and thoroughness which can be used as tools to help with one or more of five tasks involved in the environmental assessment of energy and industrial processes. The tasks are: (1) ranking individual effluent streams by the expected toxicity of their discharges; (2) establishing sampling priorities; (3) determining problem pollutants; (4) recommending best multimedia control technology alternatives; and (5) recommending control/disposal technology development programs. This model, SAM/IA, is useful for rapidly screening each effluent stream from a specific source: it is based on comparing effluent concentrations with the set of Minimum Acute Toxicity Effluent (MATE) criteria established by the EPA. The report explains the purposes of SAM/IA, the format used, and the MATE criteria against which pollutants are gauged. Several examples are included to illustrate specific facets of the model and of the format.

The Environmental Protection Agency's Industrial Environmental Research Laboratory-RTP Energy Assessment and Control Division (IERL-RTP/AECD) conducts programs to develop control technology and perform environmental assessments for both energy and industrial processes. In conducting environmental assessments, it is necessary to do one or more of the following tasks: (1) rank individual effluent streams by the expected toxicity of their discharges, (2) establish sampling priorities, (3) determine problem pollutants, (4) recommend best multimedia control technology alternatives, and (5) recommend control/disposal technology development programs. This report describes the simplest member of a sequence of Souce Analysis Models (SAMs) of increasing complexity and thoroughness which can be used as a tool to help with these five tasks. This model, SAM/IA, is useful for rapid screening of each effluent strea from a specific source. It is based on a comparison of effluent concentrations with the set of Minimum Acute Toxicity Effluent (MATE) criteria established by the EPA. This report explains the purposes of SAM/IA and describes the model embodied in SAM/IA, the format used and the MATE criteria against which pollutants are gauged. Several examples have been included to illustrate specific facets of the use of the model and of the format.
