As required under section 6(b)(4) of the Toxic Substances Control Act (TSCA), EPA is proposing to establish a process by which the Agency will determine whether a chemical substance presents unreasonable risk on injury to health or the environment. This is to be done without consideration of costs or other non-risk factors, including an unreasonable risk to a potentially exposed or susceptible subpopulation, under the conditions of use. The draft rule establishes the steps that must be completed for a risk evaluation of either those chemicals identified as high priority or in an approved request from a manufacturer. The rule enumerates the components of an evaluation including scope, hazard assessment, exposure assessment, risk characterization, and finally a risk determination. Additionally, the draft rule provides the form and manner for which manufacturers may submit a request for an Agency conducted risk evaluation and how those requests will be evaluated by the Agency.
