Testing of Certain High Production Volume Chemicals

EPA is proposing a test rule under section 4(a)(1)(B) of the Toxic Substances Control Act (TSCA) to require manufacturers (including importers) and processors of certain high production volume (HPV) chemical substances to conduct testing for acute toxicity; repeat dose toxicity; developmental and reproductive toxicity; genetic toxicity (gene mutations and chromosomal aberrations); ecotoxicity (in fish, Daphnia, and algae) and environmental fate (including five tests for physical chemical properties and biodegradation). EPA has preliminarily determined that each of the 37 chemical substances included in this proposed rule is produced in substantial quantities and that there is substantial human exposure to each of them. Moreover, EPA believes that there are insufficient data to reasonably determine or predict the effects on health or the environment of the manufacture, distribution in commerce, processing, use, or disposal of the chemicals, or any combination of these activities. EPA has concluded that this proposed testing program is needed and appropriate for developing such data. Data developed under this proposed rule will provide critical information about the environmental fat
