Regulation of existing chemicals under TSCA: information disclosure as the route to reducing risk and increasing available data.
The Toxic Substances Control Act (TSCA) empowers the Environmental Protection Agency (EPA) to regulate risk associated with the use of existing chemicals and the introduction of new chemicals into commerce. Due to a number of concerns, however, the authority to regulate existing chemicals under TSCA has enjoyed limited success. A more generic and flexible approach is needed to achieve significant risk reduction for existing chemicals. This paper presents a frame-work for a generic approach to the regulation of existing chemicals. Under this framework, EPA would officially recognize that the distribution of chemical substances without evaluating and communicating to the user how to avoid operationally undesirable exposures represents an unreasonable risk to health or the environment. Acting under the authority of TSCA, EPA would then generically require suppliers to communicate acceptable exposure levels and information regarding safe use. This framework is consistent with the express policy of TSCA, which states that development of data with respect to the effects of chemical substances and mixtures on health and the environment should be the responsibility of manufacturers and processors of chemicals. The approach outlined here is consistent with and complements initiatives of the Office of Toxic Substances (OTS) and would enable OTS to accomplish some of the fundamental goals of TSCA.
