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.
- During 2007, EPA completed the first IUR collection (called the 2006 IUR) since major amendments to the IUR were published in 2003 (PDF) (60 pp, 364 K, about PDF). To provide additional time for industry reporting, EPA extended the 2006 IUR submission period to March 2007.
EPA received updated information for approximately, at current estimates, 7,500 organic and inorganic chemicals for the 2006 IUR. For the first time, this information included:
- Manufacturing information for inorganic chemicals,
- Enhanced manufacturing information for organic chemicals (e.g., the physical form of the chemical and the number of potentially exposed workers), and
- Additional screening-level exposure-related processing and use information for organic chemicals produced at 300,000 pounds or greater at a single site.
- The Agency is using 2006 IUR exposure data in conjunction with hazard and fate data received under the High Production Volume Challenge Program to develop screening-level documents summarizing basic hazard and exposure information on HPV chemicals.
This effort, through the Chemical Assessment and Management Program (ChAMP), is helping to fulfill EPA’s commitments made in August 2007 under the Security and Prosperity Partnership. The screening-level documents will include evaluations identifying potential risks, noting scientific issues and uncertainties, and indicating the initial priority being assigned by the Agency for action, where appropriate. For more information on this effort, see the HPV, HPV Information System, and ChAMP sections of this report.
- EPA launched a new IUR information management system in 2007, consolidating information submitted to EPA online using EPA’s Central Data Exchange (CDX), on CDs and in hard copy. The new information system provides improved access to IUR information for Agency data users to make regulatory and risk management decisions. Currently, the system is only accessible to Agency users because it contains Confidential Business Information (CBI). A sub-set of the non-CBI data will be made available to the public in the future.
In an effort to ensure the data entered into the IUR information management system are as complete and correct as possible, EPA used rigorous quality control methods when populating this system, including contacting submitters with questions concerning their IUR reports, checking chemical names and identifying information, etc.
