Supplementary Documentation for an Environmental Impact Statement Regarding the Pantex Plant: Estimated Releases and Downwind Concentrations of Air Pollutants from Waste Organic Solvent Evaporation, Waste High-Explosive Burning, a

摘要

This report documents work performed in support of preparation of an Environmental Impact Statement (EIS) regarding the Department of Energy's (DOE) Pantex Plant near Amarillo, Texas. Specifically, this report discusses the following operations at the Pantex Plant that routinely emit air pollutants: evaporation of waste organic solvents contaminated with high explosives, burning of waste high explosives, and high-explosive test shots. Available experimental data and published emission factors were used to estimate the amounts of pollutants released into the atmosphere from each source. Pollutant concentrations were calculated at the main plant area and at the site boundary under both typical and unfavorable meteorological dispersion assumptions using Gaussian plume and puff models. These concentration estimates were then compared to existing air quality standards, occupational exposure limits, and, where no standards exist, to toxicological data. (ERA citation 09:038389)
