The submission of the ESDM report is required to demonstrate compliance with Ontario Reg. 346 – General – Air Pollution, under the Environmental Protection Act (EPA). Section 5 of Ontario Reg. 346 requires that the aggregate emissions from a facility be in compliance with the air standards. In June 1998, the Ministry of the Environment released a document entitled Procedure for Preparing an Emission Summary and Dispersion Modelling Report (the Procedure Document). Since October 1998, the Ministry has required that a complete Emission Summary and Dispersion Modelling (ESDM) report be submitted in support of an application for approval under Section 9 of the EPA. The Procedure Document provides clear direction on the preparation of an ESDM report and was also developed to provide greater certainty to proponents applying for approval.
