The United States Environmental Protection Agency (U.S. EPA) recently issued the final Chemical Data Reporting (CDR) Rule under the Toxic Substances Control Act (TSCA). The CDR Rule, which revises the former Inventory Update Reporting (IUR) Rule, requires importers and manufacturers of certain chemical substances listed on the TSCA Chemical Substances Inventory to report information about the manufacturing, processing and use of those chemical substances. The U.S. EPA uses CDR data to support risk screening, assessment, priority setting and management activities.  

The CDR Rule revises provisions in the former IUR rule relating to the method used to determine whether a manufacturer or importer is subject to CDR reporting; the frequency with which CDR reports must be submitted; the method of reporting; and the type of information that must be reported. One particularly notable change is the introduction of new production volume thresholds to determine whether a manufacturer or importer is required to submit a CDR report. Under the CDR Rule, manufacturers and importers are required to file a report with the U.S. EPA if the production volume of a chemical substance meets or exceeds 25,000 pounds in any calendar year since the last principal reporting year. In addition, the CDR Rule decreases, from 25,000 pounds to 2,500 pounds, the reporting threshold for chemical substances that are the subject of certain TSCA rules and orders.  

The CDR Rule took effect on September 15, 2011. Reporting under the CDR Rule for the 2010 and 2011 calendar years will commence February 1, 2012 and conclude June 30, 2012.
