On April 6, 2015, the EPA announced a proposed rule to require reporting and recordkeeping information on certain chemical substances manufactured or processed as nanoscale materials. The proposed rule applies to materials designated as chemical substances under the Toxic Substance s Control Act (“TSCA”).
According to the EPA, the rule is necessary to ensure that nanoscale materials are manufactured and used in a way to prevent unreasonable risks to human health and the environment. The rule would require manufacturers of new chemical substances to provide a pre-manufacturing notice to the agency before introducing them into commerce. Also, the rule would require information gathering on new and existing nanoscale materials.
Nanoscale materials are chemical substances which have dimensions at the nanoscale, or which are approximately 100 nanometers or less in width. By comparison, a human hair is approximately 80,000 to 100,000 nanometers wide. Nanoscale materials may have properties which are different than the same chemical substances in a larger form.
The proposed rule can be found at FR 2015-07497. The public comment period ends on July 6, 2015.
