User-friendly screening model for point-source impact assessment

Technical Report ·
OSTI ID:5813759
A user-friendly air-quality-simulation screening model coded in FORTRAN is described and sample use is shown for point-source impact assessment. The model was developed and tested on a personal computer and can be run interactively on a mainframe. Any of five dispersion techniques: (1) wind fluctuations, (2) Briggs urban, (3) Briggs rural, (4) Pasquill-Gifford, or (5) Brookhaven can be used. Plume rise can be calculated either by Briggs 1975 techniques, currently included in models used for regulatory purposes, or by techniques which calculate plume rise layer-by-layer and consider partial penetration. Maximum ground-level concentration downwind or concentrations at specific locations can be estimated. Receptor locations can be specified in four ways: (1) specific downwind distance, (2) downwind and crosswind location, (3) distance and azimuth from the source, or (4) Cartesian coordinates of both source and receptor. The model provides ground-level estimates for a single stack or ground-level source.
