II. Background

EPA is convening a public meeting to receive comments on the instructions for reporting to the 2006 partial updating of TSCA Chemical Substance Inventory Database. EPA is required by section 8(b) of TSCA to compile and update an inventory of chemical substances manufactured or imported in the United States. Every 4 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) 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 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 lbs per year to 25,000 lbs per year and established a new higher threshold of 300,000 lbs per year above which manufacturers must report additional information on down-stream 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. The public meeting may be of interest to persons currently reporting under the IUR and to manufacturers of inorganic chemical substances.

The public meeting will include a series of presentations by representatives of EPA on the instructions for reporting for the 2006 partial updating of the TSCA Chemical Inventory Database. Presentation topics will include reporting requirements, instructions for completing the reporting form, how to assert confidentiality claims, and how to submit completed reports to EPA. After each presentation, persons attending the public meeting will be invited to comment on the clarity, completeness, and usefulness of the instructions. Comments may also be submitted in writing following the public meeting. Comments should be submitted within 30 days after the meeting to receive timely attention. The purpose of the public meeting is to receive input for improving the instructions; subsequent meetings are planned for 2004, to provide training to persons who must report in 2006, under the IUR.

There is no charge for attending this public meeting
