Paul Cheung,
Terrapex

6PPD and 6PPD-Q, Environmental Fate and Transport and Current regulatory Environment

Paul Cheung

Paul Cheung is an environmental risk assessor at Terrapex with over 10 years of environmental consulting experience. Specialising in risk assessment, vapour intrusion assessment, and risk management, Paul uses his technical skills to assist clients navigate the regulatory, municipal conveyance, and transactional due diligence processes. He has a keen interest in brownfield management and development strategy and regularly consults for a broad range of public, residential and commercial real estate, and industrial clients.

 

6PPD and 6PPD-Q, Environmental Fate and Transport and Current regulatory Environment

Terrapex’s presentation will build on the overview of N‑(1,3‑dimethylbutyl)-N’-phenyl-p-phenylenediamine (6PPD) and its oxidation product, 6PPD-quinone (6PPD-q) proposed to be presented by SGS “6-PPD Quinone: Occurrence and Best Practices in Measurement”.

These compounds, which have been determined to be severely toxic to Coho salmon and other species, are known to be entering waterways from runoff containing tire wear particles.  Research is in the very early stages but is progressing rapidly.  The presentation will focus on what will be of most interest to practitioners in site assessment and remediation and will present some of the challenges associated with these emerging contaminants.

The first segment of the presentation will review what is currently known about the physical and chemical properties of 6PPD and 6PPD-q and how these influence the environmental fate and transport of the compounds through water, soil, and air, as well as their potential for bioaccumulation and toxic effects.  The second segment will review the current regulatory landscape surrounding 6PPD and 6PPD-q.  We will look at actions that have been taken or are being considered in various jurisdictions, including Canada, the USA and Europe, to monitor and/or control the use and release of these compounds. Additionally, the presentation will discuss the concerns, responses and initiatives of rubber product manufacturers and industry associations.

Samuel Lingwood,
Pinchin

Hazardous is the New Clean – Contaminate Management Supported Redevelopment

Samuel Lingwood

Samuel Lingwood has a background in mining, mechanical and environmental engineering and is a Team Leader & Senior Technical Manager within the Pinchin Remediation Team, located in the GTA. His primary focus is on soil and groundwater remedial design, evaluation/costing, and implementation – predominantly within the real estate and development sector. As a project engineer and project manager, Mr. Lingwood has widespread experience with challenging projects across Canada, including in northern and remote environments, for a variety of land use and contaminant scenarios.

Hazardous is the New Clean – Contaminate Management Supported Redevelopment

Pinchin will present a case study on a Contaminant Management Strategy that is currently being implemented on a brownfield in the GTA. Chlorinated solvents, petroleum hydrocarbons, potential off-Site migration and free product – the Site has a varied and storied past, complete with several ultimately unsuccessful remedial efforts and the well intentioned but unfortunately mismanaged handling of hazardous levels of PCBs. However, through the implementation of a robust property boundary control, hotspot remediation and isolation, and vapour intrusion mitigation and management, Pinchin is helping our Client take this diamond in the rough and polish it into a safe and economically viable asset.

Harris Switzman,
Calgary Airport Authority

PFAS Risk Management at Airports

Harris Switzman

Harris Switzman is the General Manager of Environment and Sustainability for the Calgary Airport Authority. He is a professional geoscientist, has a graduate degree in water resource engineering and a graduate diploma in water, environment and health. Harris has been with YYC coming up on 6 years and prior to that worked on watershed management in consulting and for several public sector organizations. Through his role with the Airport Authority, he is also co-chair of the Canadian Airports Council’s Environment Committee and sits on the national and North American airport PFAS working groups.

PFAS Risk Management at Airports

This presentation addresses the management of per- and polyfluoroalkyl substances (PFAS) within airport environments. It focuses on source control, contaminated site management, and risk management strategies, including the identification of PFAS sources such as spills, fire suppression activities, and tenant materials, and outlines practical approaches for minimizing environmental release and liability. The presentation discusses innovative techniques for foam transition, fire truck cleaning, and decontamination projects, along with the challenges of managing contaminated sites and the importance of regulatory compliance and adopting fluorine-free alternatives. Key lessons and questions for future research and regulatory consideration are also highlighted, emphasizing the need for comprehensive management strategies to mitigate PFAS risks at airports.

Nicholas Doucette,
QM

Soil Management Technology at the Toronto Portlands

Nicholas Doucette

Nicholas Doucette, P.Eng., QM’s National Manager for Special Projects, is an environmental contractor that is a passionate advocate for innovation in the pursuit of safer, more sustainable environmental remediation projects. He is responsible for the bidding and delivery of complex, large, and/or sensitive Environmental Remediation projects across Canada including marine, civil, and specialty construction. Mr. Doucette has worked on projects from coast to coast including the Sydney Tar Ponds, Port Lands, Port Hope, Rock Bay, and Esquimalt Harbour projects. He currently leads QM’s Toronto Port Lands Project portfolio, presently valued at over $180 million.

Soil Management Technology at the Toronto Portlands

The construction of the Toronto Port Lands Flood Protection and Enabling Infrastructure Project (Toronto Port Lands Project) is taking place in parallel with the introduction of environmental regulations that enforce the tracking of soil leaving the site.

At the Toronto Port Lands, not only are soils leaving the site tracked, but due to several reuse applications at thesite, all soils being reused require tracking, which has led to the creation of new technologies to reuse the majority of the 1 million cubic meters of soil being managed.

New technologies like 3-D digital models, GPS driven machine control and remote sensing, cloud-based truck tracking, environmental and geotechnical analytical data management and a QP approvals platform work together to form a sophisticated, integrated tracking system.

As we all know, new technologies go a long way in simplifying work and optimizing outputs, however they come with their own set of challenges.

This presentation describes the new-age soil management technologies QM now implements at sites across Canada, initiated by work at the Toronto Port Lands project.
