[Yesterday I posted](https://blogs.edf.org/health/2015/06/29/comparing-the-senate-and-house-tsca-reform-legislation-a-side-by-side/) a side-by-side providing a 35,000-foot-level comparison of how the House’s TSCA Modernization Act of 2015 ([H.R. 2576](https://www.congress.gov/bill/114th-congress/house-bill/2576)) and the Senate’s Frank R. Lautenberg Chemical Safety for the 21st Century Act ([S. 697](https://www.congress.gov/bill/114th-congress/senate-bill/697)), address the key limitations of the Toxic Substances Control Act (TSCA).

For those left wanting more, \[*UPDATED 2-15-16* [available here](https://blogs.edf.org/health/wp-content/blogs.dir/11/files/2016/02/Side-by-side-TSCA-S.-697-H.R.2576-2-14-16c.pdf)\] is a more detailed comparison of the bills relative to TSCA that lines them up on 12 major aspects of reform.

Enjoy!
