In August 2011 EPA issued the final Toxic Substances Control Act (TSCA) Chemical Data Reporting (CDR) Rule) previously referred to as the Inventory Update Reporting (IUR) Modifications Rule. The purpose of this program is to collect quality screening-level, exposure-related information on chemical substances and to make that information available for use by EPA and, to the extent possible, due to data confidentiality claims, to the public. The CDR data are used to support risk screening, assessment, priority setting and management activities and constitute the most comprehensive source of basic screening-level, exposure-related information on chemicals available to EPA.
