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.

In addition to the basic manufacturing information collected in previous reporting cycles, the 2006 cycle is the first time EPA collected information to characterize exposure during manufacturing, processing and use of organic chemicals. The 2006 cycle also is the first time manufacturers of inorganic chemicals were required to report basic manufacturing information.
