## II. Background

                    The U.S. Environmental Protection Agency is convening two workshops to train stakeholders on how to report for the 2006 Partial Updating of the TSCA Chemical Substance Inventory.  The EPA is required by section 8(b) of the Toxic Substances Control Act (TSCA) to compile and update an inventory of chemical substances manufactured or imported into the United States.  Every four years, manufacturers (including importers) of certain chemical substances on the Chemical Substance Inventory have been required to report data specified in the TSCA section 8(a) Inventory Update Rule (IUR), 40 CFR part 710.  Past updates included information on the chemical's production volume, site-limited status, and plant site information.  Amendments to the IUR promulgated in the                     **Federal Register**                     on January 7, 2003 (68 FR 848) (FRL-6767-4) expanded the data reported on certain chemicals to assist EPA and others in screening potential exposures and risks resulting from manufacturing, processing, and use of TSCA chemical substances. At the same time, EPA amended the IUR regulations to increase the production volume threshold which triggers reporting requirements from 10,000 pounds per year to 25,000 pounds per year and established a new higher threshold of 300,000 pounds per year above which manufacturers must report additional information on downstream processing and use of their chemical substances.  The 2003 amendments to the IUR also revoked the exemption from reporting for inorganic chemical substances, provided a partial exemption from reporting of processing and use information for chemical substances of low current interest, and continued the current exemption from reporting for polymers, microorganisms, and naturally occurring chemical substances.  These changes modify requirements for information collected in calendar year 2005 and submitted in 2006 and thereafter.  These workshops may be of interest to persons currently reporting under the IUR and to manufacturers of inorganic chemical substances.                

The workshops will include a series of presentations by representatives of EPA on the Instructions for Reporting for the 2006 Partial Updating of the TSCA Chemical Substance Inventory.  Subjects discussed will include reporting requirements, instructions for completing the reporting form, how to assert confidentiality claims, how to submit completed reports to EPA, and case studies illustrating different aspects of reporting. During the workshops, persons in attendance will be able to ask questions regarding the material being presented.  The purpose of these meetings is to provide training to persons who must report in 2006 under the Inventory Update Rule.
