IO employs a systematic approach for determining the potential environmental impacts of a proposed project including the natural, cultural, social, economic and built environments.


Public Work Class Environmental Assessments
For the majority of projects (or “undertakings” as per Environmental Assessment Act), IO follows the Ministry of Infrastructure (MOI) Public Work Class Environmental Assessment (PW Class EA) process. A Class EA process permits a group or “class” of projects to proceed using a self-governing environmental planning tool to assess the potential environmental effects of a given project without the need to go through an Individual Environmental Assessment under Part II of the EAA. Typically a Class EA will consider all aspects of the undertaking which may impact on the environment. Using this method of assessment ensures that consideration has been given and public consultation was undertaken where appropriate before a project may proceed.

Environmental Site Assessments (Site Investigation)
A Phase 1 environmental site assessment is the identification of potentially contaminating activities and subsequent areas of potential environmental concern through the review of historical records and an inspection of the site including surrounding areas. A Phase 2 environmental site assessment is the investigation of previously identified areas of potential environmental concern for the presence/absence of contamination through intrusive methods. Generally this process is condcuted for either regulatory compliance (i.e. Record of Site Condition filing) or for due diligence purposes.

In the case where contamination is identified at a property there are a number of choices available about what to do next. One common practice is to undertake remediation of impacted media (soil, gorundwater or air) to meet the needs of the intended future use of the property. Remediation can include removal, mass reduction, washing, containment or immobilization techniques to reduce the risk to human health and environment.

Another common process is to conduct a risk assessment which will consider the site specific human and ecological receptors at the site and the pathways to which they may be exposed. A risk assessment is a quantitative evaluation of risks at the site and may result in the generation of risk management measures to reduce the risks. Risk management measures may include barriers or access restrictions to prevent the exposure of receptors to contamination left in place. The risk assessment process can be completed for both regulatory and due diligence purposes depending on the requirements of the project.

Environmental Compliance
We provide advice regarding environmental compliance on a number of different aspects as part of the ongoing management of IO’s portfolio of properties. Generally environmental compliance will mean the adherence to Provincial and any applicable Federal regulation with regard to development and ongoing operations of a property. Typical compliance issues include permits to discharge to the environment (waste waters, air emissions or solid waste products), ongoing assessment of activities in relation to surrounding environment including noise or dust generation and assessment of environmental conditions including indoor vapour assessment.

Project Management
Overall we provide our services with sound, practical advice that helps guide our internal and external clients through the environmental assessment process. We provide added value to projects by identifying potential issues and creating solutions early in the process to avoid costly delays and expenses. Sound project management is a fundamental to our business.
