The handing and storage of aircraft fuels, rocket propellants and solvents at Air Force installations creates the potential for accidental release of airborne pollutants. Currently available dispersion models for planning and response actions do not effectively address building effects. The objectives of this study, therefore, are twofold: (1) to assess for a range of release scenarios the significance of building effects relative to overall modeling uncertainty, and (2) to assess the feasibility of producing a practical model to account for building effects for non-dense and dense gas releases. The major steps of this study include: (1) prioritize release scenarios, (2) assess building effects relative to overall modeling uncertainty, (3) select an available dispersion model to adapt for the building terms, (4) assess the feasibility of adapting the selected model to account for building effects for non-dense and dense gases, and (5) assess the feasibility of field testing the revised model.
