Last week, the House of Representatives passed the TSCA Modernization Act of 2015 (H.R. 2576), its bill to reform the Toxic Substances Control Act (TSCA). The Senate is poised to consider its own bill, the Frank R. Lautenberg Chemical Safety for the 21st Century Act (S. 697), within the next few weeks.
How would these bills address the key flaws in current TSCA? The chart below provides a 35,000-foot-level comparison of the two bills. It's also available as a PDF here.
