Inventory Update Reporting

More on Managing Existing Chemicals

The aim of the Inventory Update Reporting (IUR) program is to collect the highest quality screening-level, exposure-related information and to make that information available to EPA and the public.

Chemical manufacturing, processing and use information is reported to EPA under the IUR rule, amended in 2003 and issued under the Toxic Substance Control Act (TSCA).

Manufacturers and importers of -- at current estimates -- 7,500 organic and inorganic chemicals report basic manufacturing information for chemicals produced in volumes of 25,000 pounds or more at a site. To put this in perspective, that is out of the more than 83,000 chemicals listed on the TSCA Chemical Substances Inventory. For chemicals produced or imported in volumes of 300,000 pounds or more at a site, manufacturers also report processing and use information.

The most comprehensive source of basic screening-level, exposure-related information, the IUR data are used to support risk screening, assessment, priority setting and management activities.
