We are proposing updates to the Technical Guidance for Soil Vapour Intrusion Assessment, which builds on a draft document previously posted for public consultation in September 2013 (011-2912). Before finalizing this document, we are once again seeking comments to ensure that the updated guidance reflects the need of stakeholders.
Why consultation isn't required
The Technical Guidance for Soil Vapour Intrusion Assessment document provides technical recommendations, including best practices and technical tools to assist stakeholders (e.g. Qualified Persons) who are involved in conducting and reviewing a soil vapour intrusion assessment. This document reflects a ten-year development period in which the ministry constantly sought comments and input from key experts and stakeholders.
The purpose of this proposal is to invite comments on the guidance document. The feedback will help improve the usability and quality of the document.
The Technical Guidance for Soil Vapour Intrusion Assessment document outlines the process for how to complete a proper vapour intrusion assessment.
Previous version of draft guidance was posted on the Environmental Registry for public consultation in 2013 (011-2912). While there were a number of constructive comments, this draft document requires revisions to reflect the current state of science on vapour intrusion assessment.
Following consideration of stakeholder’s comments and further revision of this document, we are posting this updated proposal for an additional 90-day public consultation. We will review and consider all comments received from this consultation period as part of the decision-making process by the ministry.
Updates to the Technical Guidance for Soil Vapour Intrusion Assessment
As committed to in our Made-in-Ontario Environment Plan, we are taking steps to put vacant lands back to good use through the redevelopment and revitalization of brownfields, while still protecting human health and the environment.
This document reflects the current state of knowledge on vapour intrusion given the developing field of science in this area and provides best practices and a plan of action that can be considered when assessing a site for the vapour intrusion pathway. The guidance will provide a better understanding of ministry expectations. Specifically, the document includes:
- technical recommendations on characterization of soil vapour and indoor air
- an assessment process to address the vapour intrusion pathway
Other Proposed Guidance Documents
We are also seeking feedback on two other proposed guidance documents related to the RSC program, including:
- Records of Site Condition: A Guide on Site Assessment, the Cleanup of Brownfield Sites and the Filing of Records of Site Condition. Refer to ERO Notice (019-2551) for more details on this proposal.
- Procedures for the Use of Risk Assessment under Part XV.1 of the Environmental Protection Act. Refer to ERO Notice (019-2546) for more details on this proposal.
