EPA 10 Substances.pdf

On December 19, 2016 (81 FR 91927), as required by the Toxic Substances Control Act (TSCA), as amended by the Frank R. Lautenberg Chemical Safety for the 21st Century Act in June 2016, EPA published a notice of an initial list of ten (10) chemical substances that will be the subject of the Agency's chemical risk evaluations to determine whether the chemical substances present an unreasonable risk of injury to health or the environment. The law requires that EPA initiate risk evaluations on 10 chemical substances drawn from the 2014 update of the TSCA Work Plan for Chemical Assessments and that EPA publish this list within 180 days of enactment (i.e., by December 19, 2016). EPA's designation of the first ten chemical substances constitutes the initiation of the risk evaluation process for each of these chemical substances, pursuant to the requirements of TSCA section 6(b)(4). For each chemical substance, within six months from the date of publication of this notice, EPA will issue a scoping document. EPA has also established dockets for each of these chemical substances to document each risk evaluation and to facilitate receipt of information that will be useful to the Agency's risk evaluation.  The 10 chemical substances for which EPA is initiating risk evaluations are as follows:

• 1,4-Dioxane;
• 1-Bromopropane;
• Asbestos;
• Carbon Tetrachloride;
• Cyclic Aliphatic Bromide Cluster (HBCD);
• Methylene Chloride;
• N-Methylpyrrolidone (NMP);
• Pigment Violet 29 (Anthra[2,1,9-def:6,5,10-d'e'f']diisoquinoline-1,3,8,10(2H,9H)-tetrone);
• Trichloroethylene (TCE);
• Tetrachloroethylene (also known as perchloroethylene).
