Basic Information

Announcement

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.

The purpose of Chemical Data Reporting (CDR), formerly known as Inventory Update Reporting (IUR), 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, to the public. The IUR/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.

EPA uses the data to support many health, safety, and environmental protection activities. Processing and use information reported in 2012 will help EPA, other agencies, and the general public to readily screen and prioritize chemicals for the purpose of identifying potential human health and environmental effects. Returning the reporting period from every 5 years to every 4 years will assure that the public has timely access to current and improved data. This information will also provide the American people with greater access to a wide range of information on those chemicals to which their children and families are exposed every day. The requirement for improved data will enhance the Agency’s ability to more effectively identify and address potential chemical risks.

The next CDR submission period for reporting for the 2012 CDR is February 1, 2012, to June 30, 2012. The CDR regulation requires all companies to report data electronically using e-CDRweb, the CDR web-based reporting tool (formerly the e-IURweb), and EPA’s Data Exchange (CDX) system. These tools are being developed by EPA. Manufacturers (including importers) are required to report full manufacturing data for calendar year 2011 and production volume only for calendar year 2010 for all reportable chemical substances when 2011 site-specific production volume equals or exceeds 25,000 lb. Manufacturers, (including importers) are required to report processing and use data for calendar year 2011, for all reportable chemical substances when 2011 site-specific production volume equals or exceeds 100,000 lb.

Certain non-confidential data submitted previously under the IUR regulation are available for public use; see CDR/IUR Data. Some information submitted under the 2012 CDR may be claimed as confidential; however, such claims must be made at the time of submission and substantiated in accordance with the CDR rule.

Beginning with the reporting for the 2012 CDR, inorganic chemical substances are no longer exempt from the reporting of processing and use information. Read more about CDR.

IUR/CDR Reporting

Businesses required to comply with the CDR regulation should have a thorough understanding of the TSCA Inventory and the criteria used to determine the listing of a substance on the TSCA Inventory.

History

In 1977, the EPA promulgated a rule under the Toxic Substances Control Act (TSCA) section 8(a), 15 U.S.C. 2607(a), to compile and keep current an inventory of chemical substances in commerce in the U.S. This inventory is called the TSCA Chemical Substance Inventory (TSCA Inventory).

The 1986 regulation required chemical manufacturers (including importers) to report to EPA every 4 years the identity of and basic manufacturing information for organic chemical substances manufactured (including imported) in quantities of 10,000 pounds or greater annually at each plant site they own or control.

In 2003 and again in 2005, EPA amended the IUR, expanding the range of chemicals and plant sites reporting, expanding the type of data reported, raising the production volume threshold that triggers reporting, and making certain further adjustments. Beginning with the 2006 IUR requirements, every five years beginning in 2006, manufacturers and importers producing 25,000 pounds or more of a reportable chemical substance reported the identity of the chemical substance and basic manufacturing information. Additionally, manufacturers and importers producing 300,000 pounds or more had to report basic domestic processing and use information.

On August 2, 2011, EPA issued a final Chemical Data Reporting (CDR) Rule which was proposed as the Inventory Update Reporting (IUR) Modifications Rule. The final CDR rule returns the frequency of reporting to once every four years and also:

Beginning with the 2012 CDR submission period, manufacturers (including importers) are subject to the revised reporting requirements based on manufacturing (including importing) activities conducted during the principal reporting year (calendar year 2011).
