Through Significant New Use Rules, EPA is taking action to protect the public from certain chemicals that can cause health effects ranging from cancer to reproductive and developmental harm to people and aquatic organisms. Final action enables EPA to restrict or limit any new uses of these chemicals, including imported goods with these chemicals. Action addresses most uses of certain benzidine-based dyes; DnPP, a phthalate; and Alkanes C 12-13, chloro, a short-chain chlorinated paraffin.
