Workshop on Toolkits for Sustainable Remediation of Petroleum Hydrocarbons
Date: May 12, 2022 ◊ Time: 8:30 am to 12:15 pm ◊ No registration required
Shell and Contaminated Sites Approved Professional Society (CSAP) of BC
This free half-day workshop is on the Toolkits for Sustainable Remediation of Petroleum Hydrocarbons, a four-volume set of tools designed to integrate the latest science into a decision- framework to identify, evaluate and optimize remedial options for petroleum hydrocarbon-contaminated sites. These toolkits include an approach for remedial decision-making that considers the role of natural attenuation processes, and guidance and tools on conducting sustainability evaluations.
The first two toolkits, Conceptual Site Model (CSM) and Case Studies (Toolkit 1) and Methods for Monitoring and Prediction of Natural Source Zone Depletion (NSZD) and MNA (Toolkit 2), were published in 2016 to help document the latest science on NSZD and natural attenuation. In 2021, Evaluation of Remediation Technologies for Petroleum Hydrocarbon Sites (Toolkit 3) and Methods for Sustainable Remediation (Toolkit 4) were published (https://csapsociety.bc.ca/csap-toolkits/). The workshop will largely focus on Toolkits 3 and 4, leading participants through an end-to-end process for site management and closure that includes:
- developing and building upon an effective CSM;
- identifying concerns/risks and remedial objectives;
- evaluation of natural attenuation;
- selecting remedial measures and performance / transition metrics in context of sustainable approaches; and
- optimizing remedial approaches, including transition to other remedies or natural attenuation / NSZD and site closure.
The workshop will describe how to incorporate NSZD and MNA into the site remediation process, presenting the benefits of both natural and enhanced attenuation. The principles and basis for sustainable approaches will also be addressed together with a roadmap for conducting sustainability evaluations, including emerging considerations for resilient sustainable remediation and climate change. Toolkit implementation will be discussed from both a technical and regulatory (BC and other jurisdictions) perspective. Opening and closing panel sessions will be used to help frame the workshop and identify current status, possible barriers, and desired future outcomes and needs.
As a workshop participant, you will be introduced to new approaches for site remediation, including integrating quantitative evaluations of natural attenuation into the site remediation process. In addition, you will learn how to implement a step-wise, optimized approach where MNA and NSZD are often selected following active remediation. Tools will be provided on a range of technologies and use of the new Sustainability Dashboard will be demonstrated. While case examples will be on petroleum hydrocarbon-contaminated sites, many of the principles embodied in the toolkits apply broadly to contaminated sites management.
This workshop will broadly benefit individuals active in different environmental sectors, including consultants, regulatory agencies, industry, and academia. The workshop facilitators include the authors of the toolkits, who are recognized experts in their fields.
