EPA has posted Risk-Based Prioritizations and supporting documents for 28 additional chemicals that were sponsored under the High Production Volume (HPV) Challenge Program at: To date, Risk-Based Prioritizations have been posted for a total of 102 chemicals.

For a given chemical or chemical category, each Risk-Based Prioritization presents an initial recommended level of concern based on information in the supporting documents, which include a Hazard Characterization, Exposure Characterization, and Risk Characterization. EPA uses these screening-level documents to evaluate chemicals and assign initial priority for future potential action based on the risk concerns presented by these chemicals in comparison with other HPV chemicals and in light of any uncertainties presented by gaps in the available data.

The documents are primarily based on hazard, use, and exposure data available to the Agency through the HPV Challenge Program and on EPA's examination of chemical use and exposure information collected from the 2006 Inventory Update Rule (IUR) reporting as well as data from readily available sources of hazard and exposure information.
