China D4 Evaluation
In early 2018, GSC entered into a tri-party agreement with the China Association of Fluorine and Silicone Industry (CAFSI), and the Solid Waste and Chemical Management and Technology Center (SCC), to conduct an environmental risk evaluation on D4 in China. The evaluation will assess the potential risks to environmental organisms from exposure to D4 using appropriate input parameters in applicable models to predict local emissions and the environmental receptor concentrations associated with Chinese facilities that manufacture, process and/or use D4. The evaluation will include a hazard assessment, exposure assessment, risk characterization, and a risk determination for environmental exposure to D4 associated with Chinese facilities that manufacture, process and/or use D4.
The data and information resulting from this assessment should inform the need for prioritization of further assessment or any potential preventive risk management for D4.
The target timeframe for the completion of the risk evaluation is March 2019.
