Tougher dioxin, furan limits set for Récupère Sol facility
SAINT-AMBROISE, QUE-Over the next 18 months, the Récupère Sol contaminated soil treatment facility in Saint-Ambroise will be required to meet a new, more stringent limit for dioxin and furan emissions. The average annual concentration must not exceed 60 fg (10-15 kg) TEQ (femtograms, a unit slightly larger than a virus) per cubic metre. The company must also implement a rigorous monitoring program for control of these emissions, Quebec Minister of Sustainable Development, Environment and Parks Thomas Mulcair said recently. The requirements are in accordance with a ministry order issued in the fall of 2004. The monitoring program proposed by Récupère Sol for its facility was carefully analyzed by ministry specialists, who concluded that it will fulfill the requirements of the order. In addition to monitoring ambient air quality, the program will provide annual reports of polychlorinated biphenyl (PCB), dioxin and furan levels in area soils and mosses, pine needles and small mammals. Since receiving the ministry's notice of intent to issue an order, the company has made a number of modifications to its operations, notably to its system for cooling treated soils and its emergency valves. Mulcair noted that the new conditions have been included in the facility's certificate of approval.
