On June 7, 2016, the Senate passed a revised version of the “Frank R. Lautenberg Chemical Safety for the 21st Century Act” (S. 697), which the House of Representatives had already approved, to enact sweeping amendments to the Toxic Substances Control Act, 15 U.S.C. § 2601, et seq. (TSCA). The new amendments significantly strengthen and streamline EPA’s authority to take action to ban or restrict the manufacturing, processing, or use of chemicals that may pose an unreasonable risk of injury to human health or the environment. By doing so, the amendments remove a longstanding perception that TSCA presents a considerable obstacle to EPA’s ability to effectively regulate or phase out potentially harmful chemicals.
