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 dispersion modelling is often employed to address these issues. Our dispersion modelling services have been used for automotive assembly and casting plants, automotive painting operations, chemical production industries, sand and gravel processing sites and stone quarries, scrap metal recycling facilities, metal production and metal refineries, food and grain processing plants, and municipal waste treatment facilities. By utilizing our expertise in air dispersion modelling, clients are achieving their business goals within the environmental performance expectations of our modern society.
Air dispersion modelling has been used to assist clients in determining ground-level concentrations from stack emission data as part of their process for meeting regulatory requirements for ambient air quality. If process modifications are being contemplated, we can determine if these changes will comply with regulatory requirements. As well, this information can be used to determine what type of plant modification and/or air emission abatement strategy is economically viable. Provincially approved dispersion models and the U.S. Environmental Protection Agency’s UNAMAP series of dispersion models, (particularly the Industrial Source Complex 3 [ISC3] model, ISC-PRIME and the ISCAERMOD models) are employed.
