Conference
Status
Based
on public comments from the 7th Conference, the Guideline on Air Quality
Models (Appendix W to 40CFR Part 51) was substantially revised and may
be seen HERE. The public comments clearly supported many proposed
changes, notably: Regarding AERMOD, nearly every commenter urged EPA to integrate aerodynamic downwash into AERMOD (i.e., not to require ISC-PRIME for some analyses and AERMOD for others). The only cautions were associated with the need for documentations, evaluation and review of the downwash enhancement to AERMOD. As a result of AERMIC's (the American Meteorological Society (AMS)/ EPA Regulatory Model Improvement Committee) efforts to revise AERMOD, incorporating the PRIME algorithm and making a few other incidental modifications and to respond to the public's cautions, we believe that AERMOD, as modified for downwash, merits further examination of performance results. Also, since the April 2000 proposal, the Federal Aviation Administration decided to configure EDMS3.1 to incorporate the AERMOD dispersion model, and results of its performance with AERMOD only recently became available. Consequently, AERMOD and EDMS4.0, as well as other conforming changes for the Guideline, will be the subject of a separate, later regulatory action. |

Description PRIME (Plume RIse Model Enhancements)is a set of algorithms being evaluated as the next generation building downwash model. This set of algorithms has been incorporated into the latest version of the Industrial Source Complex Short Term Model (ISCST3) and the revised test bed model has been named ISC-PRIME. Various documents, source code, executable and testcase files are available below for download and evaluation. These documents, code, etc. have been placed here for historical and comparison purposes since it is expected to be replaced with AERMOD (w/PRIME). |

Description A committee, the AERMIC(American
Meteorological Society/Environmental
Protection Agency
Regulatory
Model
Improvement
Committee),
was formed to introduce state-of-the-art modeling concepts into the
EPA's air quality models. The AERMIC's focus is on a new platform
for regulatory steady-state plume modeling. This platform
includes: 1) air turbulence structure, scaling and concepts; 2)
treatment of both surface and elevated sources; and, 3)
simple and complex terrain, and 4) AERMOD with the PRIME downwash
algorithm. The modeling system has 3 components: AERMOD
- the air dispersion model; AERMET - the meteorological data
preprocessor; and AERMAP - the terrain data preprocessor. |

Description Additional information is being provided in the form of two documents relevant to the revisions of the Guideline on Air Quality Models. The revisions would enhance the Guideline by incorporating a new, general purpose dispersion model called AMS/EPA Regulatory MODel (AERMOD) to replace the existing Industrial Source Complex (ISC3) model in many air quality assessments and incorporate a new downwash algorithm - PRIME. The two documents offered below, including the Federal Register Notice, provide information on the performance of AERMOD when the model is modified in a manner suggested by public comment. |
