The report, an Environmental Assessment Report (EAR) for Wellman-Galusha low-Btu gasification systems, is part of an overall environmental assessment program for low-medium-Btu gasification technology. This EAR provides EPA administrators and program offices with a document representing the Office of Research and Development's (ORD's) research input to standards support for Wellman-Galusha gasification facilities. This EAR is a detailed evaluation and presentation of process, control, and waste stream data collected from field tests, open literature, vendors, process licensors, and computer modeling. It gives an overview of Wellman-Galusha gasification systems, including estimates of the systems' energy conversion efficiencies and capital and operating costs. It provides data characterizing the systems' input materials, process streams, products, byproducts, and multimedia discharges. It identifies pollution control alternatives for the multimedia discharges and toxic substances in the systems' products and byproducts, and estimates their costs and energy impacts. It assesses regulatory requirements for the environmental impacts of the systems. It gives data needs and recommendations for obtaining those data, and discusses the EPA program office issues and areas of concern for the Wellman-Galusha low-Btu gasification technology.
