Speech Title: Regulations and Practices for Oil Decanting in Marine Oil Spill Response Operations – Canadian Experience and Challenges
Abstract: The marine oil spill response operations could generate a large volume of liquid oily wastes (e.g., emulsified oil, non-emulsified oil, and wastewater) that can be up to 10-40 times greater than the original volume of spilled oil. Oil decanting technologies are used globally for recovering spilled oil and handing liquid wastes. However, due to the regulatory barriers and existence of persistent and toxic contaminants in decanted seawater, the discharge of decanted seawater back to ocean is prohibited by Canada Fisheries Act. In Canada decanted seawater must be barged to shore for disposal, which significantly constrains the response capacity and efficiency of oil recovery by skimmers due to limited temporary storage space in barges and long time and high cost of transportation, and this has become one of the great challenges facing the Canadian governments and oil spill response industries in Canada. The identification of the appropriate treatment endpoints or levels of acceptance is thus a critical and urgent question to be answered in Canada to move forward the regulations for disposal of decanted seawater at sea. Through a comprehensive review of current Canadian regulations and practices for decanting during oil spill response operations, this study will be focused on the assessment of the history and evolution of Canadian oil spill response system and framework, roles and responsibilities of federal and provincial governments in marine oil spill responses, existing decanting capabilities and capacities of Canadian oil spill responders, concerns from different stakeholders on decanting practices, and more importantly, identification of the bottlenecks of decanting in Canada and regulatory and technological barriers and gaps for oil decanting. Marine oil decanting regulations and practices in US and a few European countries will also be reviewed to help address the challenges and improve Canadian experience. It is expected that this study could help the public and professionals better understand the oil decanting status quo in Canada, add more decanting best practice strategies to marine oil spill response toolbox, and facilitate Canadian governments and industries to better address the challenges in oil spill regulations and practices.
