This document describes an investigation of potential public and occupational health impacts associated with operation of the small, low Btu gasifier at the University of Minnesota, Duluth (UMD). The purpose of this study is to identify and quantify, within the uncertainty limits imposed by the available data, major contributors to such impacts. Consequently, we have estimated potential occupational health impacts and the gasifier's potential for producing certain health endpoints in the general public. Endpoints are specifically noncancer acute and chronic effects (threshold effects), and cancer and SO/sub x/-related mortalities (linear, nonthreshold effects) associated with atmospheric releases (no direct releases to aquatic systems occur at the facility) and subsequent inhalation exposure to representatives of three classes of released materials - metals, organics, and criteria pollutants. Other potential pathways to public exposure (atmospherically-contaminated drinking water, ingestion of locally produced foods, etc.) should not be responsible for a significant fraction of estimated risk, given the high dilution potential of the city's drinking water source (Lake Superior), and the fact that a relatively small quantity of food is grown locally. The report is organized to provide the reader with: (1) discussion and estimation, as feasible, of gasifier worker health risks, (2) source term (release rate) data, environmental transport and population exposure information, and (3) an assessment of the general population health risk based on these exposure estimates. 82 references, 1 figure, 9 tables.
