Proposed Revisions to Odour-based Ambient Air Quality Criteria and Development of an Odour Policy Framework

Proposed Revisions to Odour-based Ambient Air Quality Criteria and Development of an Odour Policy Framework

In June 2004, the Ministry of the Environment posted on the Environmental Bill of Rights a number of postings, for a 120 day comment period, which dealt with improving Ontario’s Air Quality. These documents included a Position Paper, titled “Updating Ontario’s Regulatory Framework for Local Air Quality”,  “Air Dispersion Modelling Guideline for Ontario”, “Guideline for the Implementation of Air Standards in Ontario (GIASO)” and  Proposals for new/updated Air Standards.

The ministry proposed amendments to Ontario Regulation 346, made under the Environmental Protection Act, to introduce new air standards; update air dispersion models; provide a risk-based decision making process to address implementation issues and improve upon its clarity and enforceability.
