Chemical Data Reporting (CDR)

Previously Collected Data

EPA now refers to the Inventory Update Reporting (IUR) rule as the Chemical Data Reporting (CDR) Rule. This change was effective with the publication of the Inventory Update Reporting Modifications; Chemical Data Reporting Final Rule in August 2011. Information collected by EPA during past reporting periods is also available to the public. IUR data prior to 2006 covered organic chemicals manufactured, including imported, in volumes of 10,000 pounds or more at an individual site. Information was limited to basic manufacturing data, such as a chemical's production volume.
