Summary of Standards and Guidelines to support
Ontario Regulation 419: Air Pollution — Local Air Quality
(Includes Schedule 6 of Reg. 419 on Upper Risk Thresholds) (April 2012)
Description:
This document provides a list of air standards, guidelines and upper risk thresholds (URTs) that are used to assess the contribution of a contaminant to air quality from a single industrial or commercial facility in Ontario.
This document is intended for use primarily by an emitter who is required to develop an Emission Summary and Dispersion Modelling (ESDM) report under Ontario’s Regulation 419/05 Air Pollution – Local Air Quality (“the Local Air Quality Regulation” or “the Regulation”) under the Environmental Protection Act.
The ESDM report provides a predicted maximum point of impingement (POI) concentration of a contaminant in the vicinity of a facility and may be developed when obtaining an Environmental Compliance Approval (ECA) or in the context of various other requirements of the Local Air Quality Regulation.
