Due to advances in scientific knowledge, higher resolution raw data, stringent air quality standards, and constantly changing regulations, environmental modeling is demanding more and more from EHS professionals and their computers. All of these influences have resulted in significantly longer AERMOD model run times as compared to the predecessor regulatory model, ISCST. Instead of minutes, AERMOD runtimes for large projects can take days and terrain data file sizes routinely exceed 100 MB. To address the issue of increased runtimes, BREEZE Software offers a number of options to modelers to increase productivity while managing model complexity.

Receptors are specific locations, set up in air quality dispersion models, where ambient concentration estimates or deposition values are needed. If the model is being used to conduct an air quality analysis for regulatory purposes, it is important to identify the extent and frequency of the highest concentrations for the averaging time. Because the model run time increases with the number of receptors added, however, finding the highest concentrations can be a tricky process. If too many receptors are added, then the model could take a long time to run, but if too few receptors are added, then the highest concentrations may be missed altogether. To provide assistance, there are tools available within BREEZE AERMOD that ease the process of identifying the highest concentrations while also minimizing the model runtime.

Failure to identify and mitigate explosion hazards is a persistent cause of industrial accidents, impacting sites ranging from fertilizer storage facilities to refineries. While some explosion consequence assessments are performed to comply with regulatory requirements or industry-specific process safety standards, in many cases the potential for loss of life and property damage is overlooked until a tragedy occurs. Explosion Consequence Modeling (ECM) can provide detailed information about the possible effects of a blast, and can be used to identify and design mitigation measures. The two traditional ECM techniques have been: 1) basic phenomenological models that are very cost-effective but provide very simplistic results, and 2) computational fluid dynamics (CFD) techniques which provide great detail but are time consuming and can be prohibitively expensive. Many facilities are in need of a detailed ECM analysis to identify and mitigate explosion hazards, but require a moderate approach that can provide detailed damage and injury predictions without the high costs of CFD modeling.
For these facilities, the Explosive Damage Assessment Model (ExDAM) can provide many of the benefits of CFD modeling with a much smaller commitment of time and money. Originally developed by Dr. Frank Tatom and marketed as part of Trinity Consultants' BREEZE® Software, ExDAM expands on the basic phenomenological model concept by adding the ability to model damage and injury while accounting for the structural details of buildings as well as the shielding effect of structures and equipment on the area behind them. Thus, ExDAM provides the safety benefits of a detailed ECM study to a much wider range of facilities at risk from either conventional high explosive (HE) materials or vapor cloud explosions (VCE). Facilities around the world have used this approach to evaluate and prepare for both potential industrial explosions and potential terrorist attacks. ExDAM has been applied to a broad range of facilities, including chemical/petrochemical, military, chemical storage, oil and gas exploration, ammunition manufacturing, rocket assembly, and stadiums/public buildings.

Most AERMOD dispersion modeling is conducted using meteorological data from a nearby airport. As long as the airport is reasonably representative of your source location, there is nothing wrong with that: airports are often a source of high quality data and located near major population centers and thus, major air pollution sources.
But airport data isn't always the best option for dispersion modeling. A great example is the Los Angeles, California area. The Los Angeles airport is located right on the Pacific Ocean and to make room for its four runways, has more flat, open space than the rest of Los Angeles. If you are using AERMOD to model a facility that is only a few kilometers farther inland, and in the heart of urban Los Angeles, wind and temperature patterns at your site may be very different from those at the airport. In other parts of the world, a nearby airport simply may not exist, or it may not record an important meteorological parameter needed by AERMOD, such as cloud cover. Whatever the problem, “onsite” meteorological data can be the solution.

The potential for accidental release of toxic chemicals to the environment is a daily threat for many industrial facilities and plants. These releases can occur very suddenly and unexpectedly, putting employees and the public at risk of injury or death, and the surrounding environment at risk of damage or destruction. A consequence modeling analysis is a powerful tool (and sometimes a regulatory requirement) in order to understand the impact that a potential release could have on personnel, equipment, and the surrounding community. Modeling can be used to address a full spectrum of threats including toxic/flammable gas dispersion, explosions, and fires (thermal radiation).
Consequence modeling is used to predict the behavior of a hazardous release, and provides a better understanding of the potential impacts caused by the release. There are many benefits to performing this type of analysis, ranging from regulatory compliance to incident reconstruction.
