In March 2015 Udall sponsored Senate bill 697, the Frank R. Lautenberg Chemical Safety for the 21st Century Act, a bill to amend and reauthorize the Toxic Substances Control Act. The legislation, as amended, was signed into law by President Barack Obama on June 22, 2016. It updated the nation's safety system for thousands of chemicals in products like cleaners, paints, carpets and furniture. The bill initially faced criticism over the balance between federal and state authority to regulate chemicals, but after changes to the legislation, it earned broader support, including from liberal members of the Senate and the President. It passed by a vote of 403-12 in the House and voice vote in the Senate.
