Alan McCammon,

BC Framework

Alan McCammon

Alan McCammon is a member of the management team for the Land Remediation (Contaminated Sites) Section of British Columbia’s Ministry of Environment. His primary responsibilities focus on the areas of brownfield remediation and redevelopment, high-risk contaminated site management, compliance/enforcement, and environmental assessments involving remediation. Alan is currently leading the Province’s review of BC’s Brownfield Strategy which focuses on increasing certainty in economic and environmental outcomes, development of partnerships across the stakeholder spectrum, and delivery of a range of educational and capacity building initiatives.

BC Framework

Results-based approach to selection of remediation options under BC’s Environmental Management Act British Columbia’s regulatory framework for contaminated site remediation is a flexible regime supported by a wealth of technical and administrative guidance. Some of the flexibility of the Province’s Environmental Management Act comes from provisions related to selection of remediation options. This session, presented by one of BC’s statutory decision makers, will provide a brief overview of the opportunities for contaminated sites professionals in developing and implementing remediation plans.

Making Out the Environmental Due Diligence Defence at Trial

Environmental prosecutions in jurisdictions across Canada can result where the Crown alleges a violation of an environmental statute or regulation. Upon conviction, charges can lead to fines and/or jail terms. These are known as quasi-criminal offences. The federal government, provincial and territorial governments and municipalities lay charges under a host of environmental laws. On March 15, 2016, the Court released its decision in R v ControlChem Canada Ltd. The company was charged with five environmental offences under two provincial statutes. The charges arose from the independent actions of the company’s employee. Contrary to the company’s environmental management system, the employee drained the liquid contents of totes to an outdoor storm sewer catch basin at the company’s facility. The Court found that the discharge of liquid caused the nearby creek to turn milky white and acidic, thereby impairing the creek. Did the Court find that the company met the environmental due diligence defence and should be exonerated, or did the Court convict? Environmental due diligence cases highlight the need for corporations, their directors and officers, senior management and employees to implement an integral environmental systems approach to ensure that foreseeable and preventable environmental events and harm do not occur. Many corporations rely on their environmental advisors to provide incisive and practical advice to keep the company, its management and employees out of environmental trouble.

Parisa has applied models to soil vapor simulations for a variety of contaminated sites applications in support of remediation and risk assessment.

Soil Gas Mitigation Systems – An Emerging Practice

The field of soil gas mitigation is an emerging practice in Canada. There is increasing public awareness of the potential risks from inhalation and/or explosion of volatile chemical compounds and naturally occurring gases such as radon and methane gas. Consequently, mitigation of soil gas intrusion into buildings or enclosed spaces is increasingly required or considered as a pre-emptive strategy at many sites. For new building construction there is a range of possible mitigation solutions, which often involve sub-slab measures where passive or active venting and/or barrier systems are installed. New materials such as aerated floors provide for more efficient venting and options for using wind turbine or low-powered fans. For existing buildings there is also a range of possible mitigation solutions, with one common approach of using the existing granular layer beneath the sub-slab as a venting layer as part of a sub-slab depressurization system. Less common are measures such as building pressurization or ventilation, which may offer advantages for some sites. This presentation focus on six key points to consider for sub-slab venting systems in new and existing buildings. Key points presented include: 1) Establishing Project Objectives and Performance Goals, 2) Selected the Venting System Type, 3) System Design and Optimization, 4) Construction Testing and Inspection, 5) System Commissioning and 6) Ongoing Operation and Maintenance. A discussion on each key point along with practical examples is provided. The presentation concludes with a case study which highlights combined new build and retrofit sub-slab venting system from start to finish.

Remediation Design: Use of Bench-Scale Testing

Kevin French

Mr. French is Vice President of Vertex and has over 30 years of experience and expertise in environmental engineering, specializing in site assessment and remediation. Kevin has been involved in the design and implementation of remediation programs across Canada involving PRBs, carbon adsorption, in-situ chemical oxidation and reduction, aerobic and anaerobic biodegradation, etc. in soil, groundwater and bedrock for a variety of contaminants, including petroleum hydrocarbons, chlorinated solvents and other compounds. He holds a Bachelor’s degree in Engineering from the University of Waterloo, is a Professional Engineer and a Qualified Person in Ontario, and frequently presents on environmental site assessment and remediation at conferences and seminars across Canada.

Remediation Design: Use of Bench-Scale Testing

The success of full-scale remediation is based upon many factors, some of which may be unknown prior to commencement of clean-up efforts. Bench-scale testing can be used to define many variables, including the type and concentration of remediation amendment, the duration of remediation amendment contact with the contaminated soils and groundwater, observation or measurement of any by-products, etc. Experimenting on soils and/or groundwater collected from the site can lead to many key observations that ultimately reduces uncertainty for full-scale remediation efforts. The purpose of this talk is present various bench-scale experiments that have been completed to demonstrate the results and to present how those bench results were incorporated into the full-scale design.

Permeable Reactive Barriers for Petroleum Hydrocarbons Compounds (PHCs)

Managing dissolved contamination along property boundaries or adjacent to sensitive receptors such as residential properties or streams has long been an area of focus for the environmental industry. Risk Control Measures are often required in conjunction with risk assessment or remediation. In the 1990s the permeable reactive barrier (PRB) was pioneered – an underground permeable “wall” which is a barrier to contaminants but allows the natural flow of groundwater to continue through the subsurface wall. The initial PRB used zero valent iron (ZVI), was termed the “Iron Wall”, and was very effective and widely applied for the treatment of chlorinated volatile organic compounds (cVOCs). Unfortunately the Iron Wall is ineffective for petroleum hydrocarbons (PHCs). For more than 20 years many attempts have been made at creating a PRB for the treatment of PHCs, but until recently each technique has had serious limitations. The purpose of this talk is to showcase a new in-situ Granular Activated Carbon (GAC) based technology which has been successfully used to treat PHCs (and cVOCs) along property boundaries. The technology is referred to as a “Trap and Treat” concept. Previously the use of GAC in the subsurface has been limited due to the limited adsorptive capacity of the GAC. However, a new technology (to Canada) allows for both the adsorption and the treatment of the dissolved PHCs. Thus passive PRBs can be installed to allow for PHC plume capture and treatment over a long period of time. This talk will present the “Trap and Treat” technology and describe how the technology can be applied along property boundaries, adjacent to streams, or along other sensitive receptors. A case study will also be provided. Additionally, other emerging PHC PRB approaches will be showcased, compared and contrasted to the use of the Trap and Treat approach. The talk will conclude with general recommendations on installation techniques for PRBs for PHC treatment.
