Ultimate passage of amendments to the Toxic Substances Control Act continues to gain momentum, as the House of Representatives agreed to Senate amendments to H.R. 2576 on May 24, 2016. The House approval followed months of negotiations among lawmakers to reconcile H.R. 2576, which the House passed in June 2015, with S. 697, passed by the Senate in December 2015. Expected to be sent back to the Senate this week, H.R. 2576 likely will be considered by the Senate after June 6, 2016, after a request for unanimous consent to vote on the measure was blocked by Senator Rand (R-Kentucky).
