Air Modeling - Guidance for Air Toxics Modeling
This section provides miscellaneous guidance documents other than permit modeling or State Implementation Plan (SIP) attainment demonstrations.
Dispersion Modeling of Toxic Pollutants in Urban Areas and Appendices (PDF)(288 pp, 10 M, 1999) - EPA-454/R-99-021
Example Application of Modeling Toxic Air Pollutants in Urban Areas (PDF)(111 pp, 5.6 M, 2002) - EPA-452/R-02-003
Also available from NTIS (PB# PB2002-108218). In preparing this document, it was necessary to revise and update the techniques described in Dispersion Modeling of Toxics Pollutants in Urban Areas (ZIP)(261 K) and incorporate techniques developed in A Simplified Approach for Estimating Secondary Production of Hazardous Air Pollutants (HAPS) Using the OZIPR Model (PDF).(78 pp, 3 M, 1999)
