The Senate Environment and Public Works Committee held a hearing July 31 on the Toxic Substances Control Act as well as S. 1009, the Chemical Safety Improvement Act (CSIA), which was introduced by Ranking Member David Vitter (R-LA) and the late Senator Frank Lautenberg (D-NJ). Chairman Barbara Boxer (D-CA) expressed concern that CSIA would preempt states’ regulatory actions against toxic chemicals. Panelists before the Committee were sharply divided on whether CSIA was an improvement over TSCA or not and raised a number of concerns. Ranking Member Vitter was confident that issues raised during the hearing could be fixed with clarifying language and indicated that he and Senator Tom Udall (D-NM) would work on a manager’s amendment to insert such language.
