Chemical Data Reporting

Chemical Data Reporting - Previously Collected Data

You can find information collected by EPA during reporting periods prior to 2016 under the Chemical Data Reporting (CDR) Rule on this page.

Note: Before August 2011 the Chemical Data Reporting (CDR) Rule was called the Inventory Update Reporting (IUR) Rule. The change was effective with the publication of the Inventory Update Reporting Modifications; Chemical Data Reporting Final Rule in August 2011.

Also note that 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.
