WyCoalGas, Inc., proposes to construct and operate a coal gasification plant designed to produce a nominal 300 million standard cubic feet per stream day (MMSCF/SD) of synthetic pipeline gas. The gasification project would be located near Douglas in Converse County, Wyoming. The project region is an attainment area; the National Ambient Air Quality Standards are not violated for any of the criteria pollutants. The major sources of emissions from the project would be the following: gasification process units, coal handling and ash handling, tank storage, and stream generation. Emissions from these sources will be such as to require air quality permit review, including Prevention of Significant Deterioration (PSD) for all criteria pollutants. Beryllium, mercury, and total reduced sulfur compounds would also be emitted in amounts greater than significance levels specified by the State of Wyoming Department of Environmental Quality (DEQ) and the US Environmental Protection Agency (EPA). Dispersion modeling was employed to assess the project's impact on air quality. To determine compliance with the PSD Class II increment limits for sulfur dioxide (SO/sub 2/) and total suspended particulate matter (TSP), it was necessary to calculate the amount of increment limit currently consumed in the project area. An analysis of best available control technology (BACT) was conducted for the proposed facilities within the gasification complex. Technologies selected as BACT for these facilities are described. Selections of BACT were made on the basis of economic, energy, and environmental considerations, in conjunction with state-of-the-art technology and existing emission limitations. Construction of the proposed gasification complex will not cause any emission limitations, ambient air quality standards, or any of the increment limits to be exceeded. Also, no significant adverse impacts with respect to soils, vegetation, or visibility are expected.
