Title: Solvent Refined Coal-II (SRC-II) detailed environmental plan

This document describes environmental research which will: aid in the development of an environmentally acceptable SRC-II process; and provide data for environmental assessment of the process. The SRC-II process is described, criteria for selection of samples to undergo environmental analyses are given, and approximate timelines are presented for obtaining pertinent samples. At this time, the SRC-II process is at the pilot-plant stage of development and a demonstration facility is scheduled to begin operation in 1984. Since design criteria may change, the environmental research described in this document is organized in four phases which correlate with and will provide information early in process development. Phase I research (screening) evaluates samples from existing SRC-II facilities (pilot, process demonstration unit (PDU), bench) which may bracket potential demonstration/commercial practice in terms of physical and chemical criteria. The samples are being subjected to a battery of short-term biomedical and ecological assays. Chemical fractionation and analysis are being performed to determine compounds and compound classes of potential concern. Phase II (baseline) research will evaluate SRC-II materials which are considered most representative of potential demonstration/commercial practice. These materials will be subjected to longer-term, more-extensive biological and ecological analyses relative to effects and environmental fate. Phase III researchmore » will examine effects of process modification, control technologies and changing operational conditions on potential environmental properties of SRC-II materials. Phase IV research (onsite monitoring) will develop methods and initiate environmental monitoring for effects at the SRC-II demonstration facility and potential commercial sites. This document also describes industrial hygiene programs which must occur throughout SRC-II process development.« less
