SCREEN2 model user's guide

Technical Report · Tue Sep 01 04:00:00 EDT 1992

OSTI ID:6123025

The document presents current EPA guidance on the use of the SCREEN2 screening model. The SCREEN2 model is supported by the SCREEN2 Model User's Guide, which previously was Appendix A of Screening Procedures for Estimating the Air Quality Impact of Stationary Sources - Draft for Public Comment (PB89-159396). SCREEN2 is a PC-driven, Gaussian atmospheric dispersion model which calculates maximum 1-hour, downwind concentrations of non-reactive pollutants. Major changes in this version of SCREEN2 are the finite line segment method for area sources, addition of wind speeds in the wind speed-stability matrix for calculating concentrations, and the inclusion of a single volume source option. The structure of the computer code was modified to aid in any future revisions to SCREEN2.
