Computerised mathematical modelling is ideal for assessing likely impacts of air-borne pollutants and for assessing effects of reduced emissions. Using AERMOD or ISCST3 nesa can: model a variety of parameters and situations to ensure compliance with licence requirements or as part of an IPC/IPPC licence application. Define appropriate stack ...

based in USA
Success in air permitting requires the ability to perform air dispersion modeling. Spirit Environmental's staff is extremely familiar with the mechanisms of air dispersion models, and how changes in stack and modeling parameters affect off-site concentrations. We are up-to-date with the latest models, including ...

Air emissions from stacks, bag filters and other air emission points can cause health and nuisance problems not only in the locality but sometimes 10's of km away. Air Dispersion Modelling can predict whether there will be problems with emissions from your site and help explore the effect of various solutions. Environmental ...

based in USA
Air dispersion modeling may be required in some instances to demonstrate with National Ambient Air Quality Standards (NAAQS) and/or local ambient air regulations. Typically, ACES' documentation begins with descriptions of the source(s), existing air quality at the site, and the source characteristics, including ...

based in CANADA
Our airsheds are becoming increasingly stressed due to urbanization and economic growth. One consequence is that industrial clients are constantly challenged to address the impacts of their operations. This often means achieving the delicate balance between operational economics and regulatory requirements. Dillon's expertise in air ...

based in USA
Air dispersion modeling, also known as atmospheric dispersion modeling, atmospheric diffusion modeling, air quality modeling, and air pollution dispersion modeling, is the mathematical simulation of how air pollutants (plum) disperse in the ambient atmosphere. ...
-
based in USA
Air dispersion models are tools to assess impacts from air pollution sources. Why are these tools important? Air permit applicants must show that potential air quality impacts will not exceed specific health thresholds. If used before pollution sources are actually built, air ...

North Shore’s qualified and experienced modellers complete air quality plume dispersion modelling for our upstream and midstream Oil & Gas, Oil Sands and Power Generation clientele in western Canada. In addition to dispersion modelling services, North Shore designs and implements ambient air quality monitoring programs, ...
-
by All4 Inc.based in USA
There was a time when air dispersion modeling was a minor subset of the services that ALL4 provided to our clients. Modeling was typically conducted to support PSD permitting or state-specific air toxics requirements, for visibility analyses for assessing impacts on Class I areas, or to support the development of multi-pathway or ...

based in TURKEY
Air quality models are calculate the dispersion of the pollutants on the reseptor points in an impact area according to different atmospheric and topographic conditions. These models are used to determine likely air pollution effects of planned facilities in order to identify protecting measures. Ennotes Engineering carries out ...
