China D4 Evaluation
In early 2018, GSC entered into a tri-partite 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 of D4 in China. The intent of the evaluation is to address Chinese facilities that manufacture, process, and/or use D4. Environmental concentration monitoring of D4, D5, and D6 in China is planned for 2021. The results of this monitoring will help to inform the D4 environmental exposure and risk assessment, which is expected to be completed in 2022.
