The Toxic Substances Control Act requires that, before manufacturing a new chemical in bulk, manufacturers must submit a pre-manufacturing report’ to the EPA in which the environmental and human health impacts of the substance are assessed (including those that may derive from the ultimate disposal of the chemical).
