Redevelopment Framework for Former Service Stations
Every community has former gas station sites that occupy prime real estate locations.
Remediation is perceived as relatively straightforward yet many sites remain undeveloped
due to the challenges of value creation and regulatory delays. The Ontario Centre for
Environmental Technology Advancement (OCETA) has been working with the Canadian Petroleum
Products Institute, the Province of Ontario and other stakeholders to ensure that those
problems become a thing of the past. The Redevelopment Framework for Former Service Stations
in Ontario provides a streamlined approach for redeveloping corner gas stations. The Framework
is an on-line decision support tool that guides municipalities, property owners, developers,
and other stakeholders through the re-development of under-utilized and abandoned service station sites.
The presentation will include an overview of the framework, and the potential for application
of similar approaches in other jurisdictions.

Brownfield Redevelopment Discussion
A short discussion on industry issues and ideas for the redevelopment of former gas station brownfields that
informs policy makers to develop guidance that enables flexible, technically defensible and cost
effective approaches to return sites to productive use.

Human Health Risks from petroleum hydrocarbon (PHC) Impacts in Urban Communities - Lessons Learned Through Observations
The decision to remediate or manage risks at a site is largely based on measured impact levels exceeding soil and/or groundwater
criteria. In Alberta, these criteria are largely based on risk assessment principles developed by Health Canada and methods
based on CCME protocols. The vapour inhalation pathway remains one of the most limiting factors to development or is
predicted to present the highest health risk to humans. Key aspects of vapour intrusion modelling include phase partitioning,
dilution factors and predicted vapour concentrations. The differences in predicted health risks based on realistic verses
conservative assumptions for these aspects can be very dramatic. This presentation will discuss the uncertainties and the
conservative nature of methods used to evaluate PHC impacts to human health with the aid of examples.

Developing an Interim Land-use Strategy: A Tool for Activating Brownfields
Introduction
Brownfield sites that are undergoing longer term remediation or on-going exposure control
often remain vacant until which time the property owner is able to sell or pre-determined
remediation end-points are met (usually generic levels appropriate for the most sensitive
land-use in the current zoning). Also, there are situations where brownfields have undergone
significant remediation, but remain undeveloped because the business case does not show there to
be an acceptable return on investment for fully developing the site. These properties can be
community blights and stifle community revitalization efforts. One potential tool to address
brownfields of this nature is to promote desirable interim land-uses while waiting for improved
economic conditions that are more conducive to permanent redevelopment.
Essentially, an interim land-use strategy proposes temporary, economically viable, community
supported uses of brownfield properties whose redevelopment is not going to occur in the near term.
In exchange for an agreement to allow for these temporary uses, owners of the properties are provided
with a portion of the revenue associated with the interim land-use (e.g. percentage of a mobile
market's revenue) or some other incentive in the case of non-revenue generating interim land-uses
(e.g. public art). This type of strategy can allow for lower remediation/management costs to the
land owner while at the same time stimulating economic activity and/or meeting community social objectives.
Once the remedial endpoints are reached at the site and a viable, permanent development opportunity is
identified by the property owner, the interim land-use would be discontinued.
