China D4 Evaluation
In December 2017, the China Ministry of Environmental Protection (the “MEP”) drafted a Catalogue on Prioritized Chemicals (First Batch) which included D4. The silicones industry believes that a D4 risk assessment in China should be completed before any regulatory decisions for D4 are made and requested that D4 be removed from the current draft of China’s priority chemical list. The MEP agreed to the request. The silicones industry provided a proposal to conduct a D4 environmental risk assessment to understand potential risks, if any, associated with release of D4.
