Tuesday night, the House passed legislation aimed at reforming the Toxic Substance Control Act (TSCA), the 1976 law that for almost 40 years has dictated how chemicals are managed in the United States. Passed with broad bipartisan support — with the only no vote coming from Rep. Tom McClintock (R-CA) — the bill is a first step toward reforming TSCA, largely considered one of the most ineffective environmental laws in the country.
