On November 29, the US Environmental Protection Agency (US EPA) announced the first 10 chemicals it will evaluate for potential risks to human health and the environment under the recently amended Toxic Substances Control Act (TSCA). US EPA will evaluate the 10 chemicals to determine whether they “present an unreasonable risk of injury” to health or the environment “under the conditions of use.” Within six months, US EPA must release a scoping document for each of these 10 chemicals, which includes the hazards, exposures, conditions of use and the potentially exposed or susceptible subpopulations that US EPA plans to consider in the risk evaluation. US EPA must complete the risk evaluations within three years (although the Agency may extend the deadline for up to six months if additional data or testing is needed).
