If the SCREEN 3 ambient impacts are higher than the above referenced standards for the emitted pollutants, then additional modeling analyses will be required. Although EPA has replaced by AERSCREEN), CALPUFF, or CALSCREEN. Exceptions must be approved by the Air Quality Division (‘Division’) on a case-by-case basis. 3. Seasonal restrictions. These refined dispersion models are listed in Appendix W (PDF) (45 pp, K, About PDF) and are required to be used for State Implementation Plan (SIP) revisions for existing sources and for New Source Review (NSR) and Prevention of Significant Deterioration (PSD) programs. The models in this section include the following: AERMOD Modeling System - A steady-state plume model that . Apr 24,  · BREEZE AERSCREEN also includes conversion factors to estimate “worst-case” 3-hour, 8-hour, hour, and annual concentrations. These concentration estimates are intended to be equal to or greater than the estimates produced by AERMOD with a fully developed set of meteorological and terrain data, however the degree of conservatism will vary.

AERSCREEN is the recommended screening model based on AERMOD. The model will produce estimates of "worst-case" 1-hour concentrations for a single source, without the need for hourly meteorological data, and also includes conversion factors to estimate "worst-case" 3-hour, 8-hour, hour, and annual.
