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)(268 K, 06-30-1999) 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 MB, 12-01-1999, 454_R-99-054)
