Compliance with air standards is demonstrated through the preparation of a document called an Emission Summary and Dispersion Modelling (ESDM) Report.
An ESDM Report summarizes all air emissions from a facility and assesses their impacts against ministry standards and guidelines.
Over the regulation phase-in period, specific industry sectors are required to complete and update their ESDM Reports annually. These documents may be requested by ministry staff when they perform inspections or audits of these facilities.
This same type of document is required when a facility makes an application for a certificate of approval to install, operate, or modify any device that emits contaminants into the air. ESDM reports are also required for requests for altered standards.
