ORTECH knows Emissions Summary and Dispersion Modelling (ESDM) Reports

Both Environmental Compliance Approval (ECA) and Air Assessed Environmental Activity Sector Registry (" EASR") require an Emissions Summary and Dispersion Modelling report.  An Emissions Summary and Dispersion Modelling ("ESDM") Report is a report that, as its name implies, covers an assessment of air pollution emissions from a facility, and how they disperse after they are released. An ESDM report must specifically include the content listed in, and use the methodologies described in, section 26 of O. Reg. 419/05. This regulation also lists when a facility is required to prepare an ESDM report. Click here for our Air Quality Compliance brochure.
