Industry representatives have asked lawmakers to consider further changes to the Democrat-sponsored bill to overhaul the Toxic Substances Control Act (TSCA), saying it would stifle innovation and create a safety standard that is nearly impossible to meet. Members of the House Energy and Commerce Committee heard testimony on changes to the bill made since the release last April of a discussion draft. Since then, the negotiation process appears to have deepened the divide between industry and NGOs, which had initially said they would prefer to present a united front when working on revisions to the law. Environmentalists say industry’s position of being an advocate of reform has not been borne out during the negotiations.
