On May 23, the late Sen. Frank Lautenberg (D-NJ) and Sen. David Vitter (R-LA) introduced the Chemical Safety Improvement Act of 2013. The bill would amend the 1976 Toxic Substances Control Act, the nation's primary and outdated chemical safety law. Despite being promoted as a significant reform, the proposed legislation fails to improve the health and safety protections missing from current law. As it stands, it represents a significant retreat from the Safe Chemicals Act of 2013 that Lautenberg introduced earlier this year. The earlier bill should be the senator’s legacy.
