IUR Changes to CDR - Chemical Data Reporting Rule

EPA issued the final TSCA Chemical Data Reporting (CDR) Rule previously referred to as the Inventory Update Reporting (IUR) Modifications Rule. The final CDR Rule, issued under the Toxic Substance Control Act, requires new and updated exposure information and increases public access to a wide range of information on every day chemicals and limits confidentiality claims by chemical manufacturers. EPA provided a fact sheet outlining details.

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.

Who Is Required To Report?
You may be affected by this action if you manufacture (including manufacture as a byproduct or import) for commercial purposes chemical substances listed on the TSCA Inventory and produced in volumes of 25,000 lb or more during the principal reporting year (i.e., calendar year 2011). Potentially affected entities may include, but are not limited to:

• Chemical substance manufacturers and importers (North American Industry Classification System (NAICS) code 325 and 324110; e.g., chemical substance manufacturing and processing and petroleum refineries).
• Chemical substance users and processors who may manufacture a byproduct chemical substance (NAICS codes 22, 322, 331, and 3344; e.g., utilities, paper manufacturing, primary metal manufacturing, and semiconductor and other electronic component manufacturing).

When Is Reporting Required?
The 2012 submission period, during which 2011 manufacturing, processing and use and 2010 production volume information would be reported, is scheduled to occur February 1, 2012 to June 30, 2012. Subsequent recurring submission periods are from June 1 to September 30 at 4–year intervals, beginning in 2016.
