Part IV 2005 – Federal Register Recent Federal Regulation Documents

The Toxic Substances Control Act (TSCA) Interagency Testing Committee (ITC) transmitted its Fifty-Fifth Report to the Administrator of EPA on December 8, 2004. In the 55\th\ ITC Report, which is included with this notice, the ITC is revising the Priority Testing List by adding a category of high production volume (HPV) orphan chemicals and requesting that EPA add these chemicals to the TSCA section 8(a) Preliminary Assessment Information Reporting (PAIR) rule and the TSCA section 8(d) Health and Safety Data Reporting (HaSDR) rule. The ITC is also removing the following chemicals from the Priority Testing List: 3-amino-5-mercapto-1,2,4-triazole; glycoluril; benzenamine, 3-chloro- 2,6-dinitro-N,N-dipropyl-4-(trifluoromethyl)-; stannane, dimethylbis[(1-oxoneodecyl)oxy]-; benzene, 1,3,5-tribromo-2-(2- propenyloxy)-; and1-triazene, 1,3-diphenyl-.]. Since the 55\th\ Report was ITC transmitted to the Administrator and made publicly available on https://www.epa.gov/opptintr/itc/, five HPV orphan chemicals have been removed from the Priority Testing List because chemical manufacturers committed to prepare robust summaries for these chemicals in response to the HPV Challenge Program. The ITC encourages other manufacturers to make similar commitments so their chemicals can be removed from the Priority Testing List and potentially avoid being added to PAIR and HaSDR rules.
