The commonly used advanced air dispersion models are AERMOD and CALPUFF. Advanced air dispersion modelling exercises using these models are typically required to demonstrate compliance when applying for an Environmental Compliance Approval (ECA) for facilities with NAICS codes under Schedules 4 and 5 of Ontario Regulation 419/05 (Reg.419) and for facilities that wish to use Schedule 3 standards as specified in Reg. 419; and to support air quality impact assessments.
BCX's modelling team provides expertise in the application of the following air dispersion models in support of ECA applications, air impact assessments and other special source studies such as road and odour:
- O.Reg.346 Model
- Screen 3
- ASHRAE (Self-Contamination)
- ISCST3, ISC-Prime
