EPA Posts TSCA 8(e) Submission for Carbon Nano Tubes
Last week, the U.S. Environmental Protection Agency posted a submission made by BASF Chemical Company under Section 8(e) of the Toxic Substances Control Act (TSCA), which requires U.S. chemical manufacturers, importers, processors and distributors to notify EPA within 30 calendar days of new, unpublished information on their chemicals that may lead to a conclusion of substantial risk to human health or to the environment. In its July 8, 2008, submission, BASF submitted the results of a subchronic inhalation study in rats, reporting that the no observed effect concentration is below 0.1 mg/m3. In a September 9, 2008, letter, EPA’s Office of Pollution Prevention and Toxics (OPPT) states that it conducts preliminary screens of all Section 8(e) submissions and routinely requests additional information from submitters to complete these preliminary screens or to evaluate submissions further. OPPT requested the complete report from BASF.
