Public advocacy groups say the Trump administration failed to adequately assess the environmental and public health risks posed by asbestos in a required chemical risk evaluation. SAN FRANCISCO (CN) — On the heels of recent court victories over how toxic chemicals must be evaluated, advocacy groups asked the Ninth Circuit on Tuesday to invalidate a recent Trump administration risk assessment for asbestos that critics say is legally flawed. Joined by a coalition of public health and environmental advocates, Asbestos Disease Awareness Organization is asking the San Francisco-based appeals court to review the U.S. Environmental Protection Agency’s final risk evaluation for asbestos.
