On December 17, 2015, the full Senate passed the *Frank R. Lautenberg Chemical Safety for the 21st Century Act* ([S. 697](https://www.congress.gov/bill/114th-congress/senate-bill/697), the *Lautenberg Act*), which would amend the nearly 40-year-old Toxic Substances Control Act (TSCA).

The House of Representatives already passed its TSCA reform bill in June, the *TSCA Modernization Act of 2015*, [H.R. 2576](https://www.congress.gov/bill/114th-congress/house-bill/2576).

Next up in the New Year will be efforts to reconcile these two bills. In anticipation of this, I am posting here updated analyses of the two bills that examine how and to what extent they would address key flaws in TSCA. These analyses include:

- brief and detailed side-by-sides of TSCA and the two bills,
- a comparison of how the bills deal with the contentious issue of preemption of state authority,
- a comparison of how well the bills meet the Administration’s principles for TSCA reform, and
- an earlier blog post on the importance of understanding which chemicals are in use today.

All of these materials (including this post) are available at [blogs.edf.org/health](https://blogs.edf.org/health/).
