EXECUTIVE SUMMARY
This document describes the status of health and environmental research
efforts (1976 to the present), supported by the U.S. Department of Energy (DOE),
to assist in the development of environmentally acceptable coal liquefaction
processes. Four major direct coal liquefaction processes are currently in (or
have been investigated at) the pilot plant stage of development. These in-
clude two solvent refined coal processes (SRC-I and -II), H-coal (a catalytic
liquefaction process) and Exxon donor solvent (EDS).
Several organizations were selected by DOE to study the health, environ-
mental and safety aspects of direct coal liquefaction processes. The Pacific
Northwest Laboratory (PNL) was assigned responsibility for evaluating SRC pro-
cess materials and prepared comprehensive health and environmental effects re-
search program plans for SRC-I and -II. A similar program plan was prepared
for H-coal process materials by the Oak Ridge National Laboratory (ORNL). A
program has also been developed for EDS process materials by Exxon Research
and Engineering Co. These programs were initiated in FY 1976 and 1981, re-
spectively.
Objectives of DOE's environmental research program are to:
â– identify and perform research on the long-term health and environ
mental issues associated with direct coal liquefaction
* evaluate control technology and ameliorative options to permit the
design of environmentally acceptable coal liquefaction processes
• assess and quantify potential risks to man and the environment from
large-scale deployment of direct coal liquefaction processes.
The program includes short-term screening of coal-derived materials for
potential health and ecological effects. Longer-term assays are used to eval
